CSci 430: Programming Project #3
Deadlock Detection
Spring 2019
Dates:
Assigned: Monday February 25, 2019
Due: Wednesday March 13, 2019 (before Midnight)
Objectives:
ˆ Learn more about Deadlock algorithms.
ˆ Better understand how we can algorithmically detect deadlocks on a
system.
ˆ Use C/C++ to implement vector and matrix data structures, get prac-
tice in creating and using such data structures in C/C++.
Description:
Our textbook gives the following algorithm (pg. 276) for algorithmically
detecting if a deadlock is present or not in a system. It requires that the
system keep an Allocation matrix A, listing which resources are currently
allocated to which processes, and the available vector V, which gives the
amount of each resource currently available in the system. In addition, the
deadlock detection algorithm requies a request matrix Q, which keeps track
of the amount of each resource each process is currently requesting from the
system. The algorithm is:
1. Mark each process that has a row in the Allocation matrix of all zeros.
2. Initialize a temporary vector W to equal the Available vector A.
1
3. Find an index i such that process i is currently unmarked and the i th
row of Q is less than or equal toW. That is, Qik ≤ Wk, for 1 ≤ k ≤ m.
If no such row is found, terminate the algorithm.
4. If such a row is found, mark process i and add the corresponding row of
the allocation matrix toW. That is, setWk = Wk+Aik, for 1 ≤ k ≤ m.
Return to step 3.
A deadlock exists if and only if there are unmarked processes at the end
of the algorithm. Each unmarked process is deadlocked.
In this assignment we will implement the deadlock detection algorithm.
Your program will be given a �le that describes the A allocation matrix
and the Q request matrix, representing the current state of all allocations
and requested allocations in the system. Your program will implement the
deadlock detection algorithm described above. The result of your program
will be one of 2 outputs:
1. If no deadlock exists, the program will display No Deadlock on stan-
dard output.
2. If a deadlock does exist, the program will display Deadlock: P0, P1,
P2 on standard output, where P0, P1, P2 are the processes that the
algorithm determined to be deadlocked in the system.
State simulation �le formats
I have provided a p3-start.cpp template that can open up and read in the
process/resource state simulation �les used for this assignment. Here we
discuss a bit more the format of these �le. I have provided 2 or 3 exam-
ple simulations, with expected correct answers, for you to use to test your
implementations with.
The input �les needed for this assignment need to contain the information
found in theV available vector and theA allocation andQ request matrices.
In the following I use r as the number of resources and p as the number of
processes. Thus the general format of the input �le is:
r p
V1 V2 V3 ... Vr
A11 A12 ... A1r

BestBank prides itself on having up-to-date information on the current account balance of its customers. To do this, BestBank relies on a company-wide information system. Customers are the heart of the BestBank information system. Customers are characterized by their customer number (unique), first name, last name, address, and date of birth. A customer can have multiple accounts into the BestBank information system. Accounts are characterized by their account number (unique), account type (i.e. everyday, savings, business) and amount and they must be assigned to a specific customer. To keep track of their spending habits BestBank customers can review all the transactions executed using their accounts. A transaction must be associated with a specific account, and each account can have multiple transactions. Finally, each transaction is characterized by a transaction id (unique), a transaction type (i.e. withdraw or deposit) and the transaction amount.
Question B: Create the Entity-Relationship Diagram and the Relational Schema for the following scenario
BestDelivery prides itself on having up-to-date information on the status of shipped item. To do this, BestDelivery relies on a company-wide information system. Items are the heart of the BestDelivery information system. Items are characterized by their item code (unique), delivery status, and destination address. Items are assigned to couriers who are in charge of their delivery. A courier delivers several items in a day. Couriers are characterized by their employee number (unique), first name, last name, and driving license.
Question C: Create the Entity-Relationship Diagram and the Relational Schema for the following scenario
BestFreelancer prides itself on having the most efficient platform through which is possible to find freelancers for any type of work. Freelancers can freely register on the platform and provide information about all the projects they have completed. To do this, BestFreelancer relies on a company-wide information system. Freelancers are the heart of the BestFreelancer information system. Freelancers are characterized by their profile code (unique), first name, last name, and email. Freelancers can list, within their profile, as many projects as they want. Projects are characterized by their project code (unique), start date, end date, project title, and project description.

Programming Assignment #2
CSci 430 Spring 2019
Dates:
Assigned: Monday February 4, 2019
Due: Wednesday February 20, 2019 (before Midnight)
Objectives:
ˆ Explore the Process state models from an implementation point of
view.
ˆ Practice using basic queue data types and implementing in C.
ˆ Use C/C++ data structures to implement a process control block and
round robin scheduling queues.
ˆ Learn about Process switching and multiprogramming concepts.
Description:
In this assignment you will simulate a Three-State process model (ready,
running and blocked) and a simple process control block structure as dis-
cussed in Chapter 3. Your program will read input and directives from a
�le. The input describes a time sequence of events that occur. These are the
full set of events you will simulate:
1
Event Description
cpu The processor executes for 1 time step the currently running process
new A new process is created and put at tail of the ready queue
done The currently running process has �nished
wait X The currently running process has done an I/O operation and
is waiting on event X
event X Event X has occurred, the process waiting on that event should
be made ready.
The input �le will simply be a list of events that occur in the system, in
the order they are to occur. For example:
----- simulation-01.sim --------
new
cpu
cpu
cpu
new
cpu
cpu
cpu
cpu
wait 1
cpu
cpu
event 1
cpu
cpu
done
cpu
cpu
cpu

exit
----------------------------------
Your task is to read in the events, and simulate the creation and execution
of processes in the system as they move through the various three-states of
their process life cycle. You need to:
2
ˆ De�ne a simple process control block (PCB) to hold information about
all processes currently running in your system. The PCB can be a
simple C struct or a C++ class. At a minimum you need to have a
�eld for the process identi�er and the process state (Ready, Running or
Blocked). You need to also keep track of the time step that the process
entered the system, and the number of steps the process has been
running. Minimal credit will be given to programs that at least handle
new events and create a process in a simulated PCB. You probably
need a list or an array to hold the current processes that have been
created and are being managed by your simulated system.
ˆ You will need a ready queue of some kind. You should use a C++
Standard Template Library (STL) container to manage your ready
queue.
ˆ You will need to implement a simple dispatcher function. Whenever
a cpu event occurs, and no process is currently running, you should
select the next Ready process from the head of your ready queue and
start it running on the processor.
ˆ You need to also implement a simple time slicing mechanism. The
time slice value to use will be passed into your program when it is
started. At the end of a cpu cycle, you should check if the currently
running process has executed for its full time quant ...

When a process makes a system call, the kernel looks up the appropriate system call function using a system call number, copies any parameters from the user stack to a kernel data area, and then executes the system call code in the kernel; if successful, it returns any values to registers, but if an error occurs, it sets a carry bit and error number to return instead. The system call handler then returns control back to the library routine that invoked the system call trap instruction initially.

This document discusses machine learning with Spark. It provides an overview of loading taxi trip and fare data from CSV files stored in S3 into a Spark DataFrame. It then performs data transformations on the DataFrame like filtering, adding new columns, and assembling feature vectors. Finally, it trains a linear regression model in a Spark ML pipeline using the transformed data, splitting it into training and test sets. It provides parameters for the linear regression and trains the model, making predictions on the test data. The document concludes by offering tips for getting started with Spark ML, including setting up a development environment and finding open datasets to experiment with.
The document contains summaries of code snippets and explanations of technical concepts. It discusses:
1) How a code snippet with post-increment operator i++ would output a garbage value.
2) Why a code snippet multiplying two ints and storing in a long int variable would not give the desired output.
3) Why a code snippet attempting to concatenate a character to a string would not work.
4) How to determine the maximum number of elements an array can hold based on its data type and memory model.
5) How to read data from specific memory locations using the peekb() function.

Assignment 02: Process State Simulation
CSci 430: Introduction to Operating Systems Fall 2020
In this assignment we will simulate a three-state process model (ready, running and blocked) and a simple process control block structure as introduced in Chapter 3 of our textbook. This simulation will utilize a ready queue and a list of blocked processes. We will simulate processes being created, deleted, timing out because they exceed their time quantum, and becoming blocked and unblocked because of (simulated) I/O events.
Questions
How does round robin scheduling work?
How does an operating system manage processes, move them between ready, running and blocked states, and
determine which process is scheduled next?
What is the purpose of the process control block? How does the PCB help an operating system manage and
keep track of processes?
Objectives

Introduction
In this assignment you will simulate a three-state process model (ready, running and blocked) and a simple list of processes, like the process control block structure as discussed in Chapter 3. Your program will read input and directives from a file. The input describes events that occur to the processes running in the simulation. These are the full set of events that can happen to and about processes in this simulation:
In addition to these events, there are 2 other implicit events that need to occur before and after every simulated event 1
listed above.
Action dispatch
timeout
Description
Before processing each event, if the CPU is currently idle, try and dispatch a process from the ready queue. If the ready queue is not empty, we will remove the process from the head of the ready queue and allocate it the CPU to run for 1 system time slice quantum.
After processing each event, we need to test if the running process has exceeded its time slice quantum yet. If a process is currently allocated to the CPU and running, check how long it has been run on its current dispatch. If it has exceeded its time slice quantum, the process should be timed out. It will be put back into a ready state, and will be pushed back to the end of the system ready queue.
The input file used for system tests and simulations will be a list of events that occur in the system, in the order they are to occur. For example, the first system test file looks like this:
----- process-events-01.sim -------- new
cpu
cpu
cpu
new

block 83

unblock 83

CSC2402 Assignment 3
This assignment is marked out of 100 marks. It is worth 10 % of your overall course mark.
Submit your assignment on‐line using the link to Assignment 3 on the course web page.
Assignment 3 consists of one task. For Assignment 3 you must submit all four files listed below in a single ZIP
file (not RAR). All four files must be in pure text format. No PDF, HTML, Word files, Open Office files, RTF
etc. and no compression or archiving such as zip, rar, tar etc. Please name your files to match the names
listed.
task_3.cpp – holds main() function,
exception.cpp – class file for exception handler functions,
exception.h – class definition file for exception handler functions, and
task_3.txt – copy of compilation messages and sample runs.
The steps to copy the compilation messages and sample runs for the task_3.txt file are software dependent:
If you are using Codelite, the compilation messages can be copied and pasted with the usual crtl‐c
and crtl‐v. For output of sample runs, right click the title bar of the command window, select
EDIT/MARK and then highlight the output. With the output selected, right click the title bar of the
command window, select EDIT/COPY. Position your cursor to a (new) text file opened in a text editor
such as Notepad, and crtl‐v will paste the copied output to the text file.
If you are using MinGW, right click the title bar of the command window; select EDIT/MARK and
then high light the output. With the output selected, right click the title bar of the command
window, select EDIT/COPY. Position your cursor to a (new) text .
The document discusses creating an optimized algorithm in R. It covers writing functions and algorithms in R, creating R packages, and optimizing code performance using parallel computing and high performance computing. Key steps include reviewing existing algorithms, identifying gaps, testing and iterating a new algorithm, publishing the work, and making the algorithm available to others through an R package.
Apache HTTP Server project continues to develop, and so does PVS-Studio analyzer, growing even more powerful with every new version. Let's see what we've got this time.
This document discusses the evolution of systems performance analysis tools from closed source to open source environments.
In the early 2000s with Solaris 9, performance analysis was limited due to closed source tools that provided only high-level metrics. Opening the Solaris kernel code with OpenSolaris in 2005 allowed deeper insight through understanding undocumented metrics and dynamic tracing tools like DTrace. This filled observability gaps across the entire software stack.
Modern performance analysis leverages both traditional Unix tools and new dynamic tracing tools. With many high-resolution metrics available, the focus is on visualization and collecting metrics across cloud environments. Overall open source improved systems analysis by providing full source code access.
This document summarizes the analysis of pump failure data from three different datasets - Kirlosker, KSB, and a turbine/compressor dataset. The data is extracted from multiple excel files into R and combined. Dates are standardized and the number of days between installation and first failure is calculated for each pump. The failure notification dates are arranged in descending order for each pump and the number of days between failures is found. The analysis aims to understand pump reliability and failure patterns over time.
This is a brief introduction to how R can be useful in the manufacturing sector to calculate the frequency of faults and then developing the model so that preventive maintenance can be done
The document discusses using JDBC (Java Database Connectivity) for object-relational mapping in Java. It covers connecting to databases, executing SQL statements and queries, working with ResultSets, and best practices for managing database connections. Key points include using the DriverManager class to obtain database connections, preparing statements for parameterized queries, and implementing a DAO (Data Access Object) layer to encapsulate data access logic.
The document discusses Java user input using the Scanner class and various control flow statements in Java including if, if-else, and switch-case statements. It provides examples of how to take user input using the Scanner class and its nextLine() method. It then explains the logic and syntax of if, if-else and switch-case statements, including the use of boolean expressions and logical operators. It also discusses nested if statements and the purpose of the break statement in switch-case blocks.
SQL Performance Tuning and New Features in Oracle 19cRachelBarker26
What's new in Oracle 19c (and CMiC R12) and the reporting software Jaspersoft Studios. If you are not interested in Jasper go ahead and skip to page 26. Explains how to read an execution plan and what to look for in an optimized execution plan.
The document discusses procedures and recursion in machine level programming. It describes how procedures use stack frames to pass arguments, save registers, and allocate local variables. Stack frames contain saved registers, arguments, local variables, and return addresses. Calling a procedure involves pushing this information onto the stack. Returning involves popping this information off the stack. Recursive procedures work because each call has its own private stack frame that does not interfere with other calls.
The document outlines the schedule and objectives for an operating systems lab course over 10 weeks. The first few weeks focus on writing programs using Unix system calls like fork, exec, wait. Later weeks involve implementing I/O system calls, simulating commands like ls and grep, and scheduling algorithms like FCFS, SJF, priority and round robin. Students are asked to display Gantt charts, compute waiting times and turnaround times for each algorithm. The final weeks cover inter-process communication, the producer-consumer problem, and memory management techniques.
This document contains instructions for several Java programming exercises involving classes, packages, inheritance, overriding, exceptions, and threads. It outlines code for programs that demonstrate concepts like classes and objects, command line arguments, bitwise operators, method overriding, and packages. For each exercise, it provides the aim, algorithm, sample code, input/output, and result to verify the output. The exercises are intended to help students learn and practice core Java programming concepts.

The company offers workshops, training, consulting and custom development services. The talk will cover reading and writing lambdas, capturing vs non-capturing lambdas, transforming imperative code to streams, mixing imperative and functional code, and taking Q&A.
This document provides an overview of machine learning concepts and code examples in Python. It discusses the typical 5 steps of machine learning projects: collaboration, data collection, clustering, classification, and conclusion. Code snippets demonstrate each step, including collecting data with Scrapy, clustering with k-means, classification with support vector machines, and evaluating results with a confusion matrix. Dimensionality reduction techniques like principal component analysis are also covered.

Assignment 02: Process State Simulation
CSci 430: Introduction to Operating Systems Fall 2020
In this assignment we will simulate a three-state process model (ready, running and blocked) and a simple process control block structure as introduced in Chapter 3 of our textbook. This simulation will utilize a ready queue and a list of blocked processes. We will simulate processes being created, deleted, timing out because they exceed their time quantum, and becoming blocked and unblocked because of (simulated) I/O events.
Questions
How does round robin scheduling work?
How does an operating system manage processes, move them between ready, running and blocked states, and
determine which process is scheduled next?
What is the purpose of the process control block? How does the PCB help an operating system manage and
keep track of processes?
Objectives
• Explore the Process state models from an implementation point of view.
• Practice using basic queue data types and implementing in C.
• Use C/C++ data structures to implement a process control block and round robin scheduling queues. • Learn about Process switching and multiprogramming concepts.
• Practice using STL queues and list data structures.

1. The key elements of supplier measurement are quality, delivery, and price. On the surface this appears to be a simple matter, but what are the complicating factors?
2. David Atkinson, the founder and Managing Director of Four Pillars, a management consulting and training company, states that “supplier relationship management is . . . process-focused. It’s a lot more about how the organization systematically plans, than it is about an ’interpersonal’ skill set of the procurement person or relationship manager.” Do you agree or disagree with this statement?
3. Supplier performance measurement is an essential lever for successful supplier management that encompasses both pre- and post-contract management. From this vantage point, how would you distinguish the focuses of supplier performance measurement undertaken pre-contract stage versus post-contract stage?

1. Text mining – Text mining or text data mining is a process to extract high-quality information from the text. It is done through patterns and trends devised using statistical pattern learning. Firstly, the input data is structured. After structuring, patterns are derived from this structured data and finally, the output is evaluated and interpreted. The main applications of text mining include competitive intelligence, E-Discovery, National Security, and social media monitoring. It is a trending topic for the thesis in data mining.
Some research needs
Problem definition – In the first phase problem definition is listed i.e. business aims and objectives are determined taking into consideration certain factors like the current background and future prospective.
Data exploration – Required data is collected and explored using various statistical methods along with identification of underlying problems.
Data preparation – The data is prepared for modeling by cleansing and formatting the raw data in the desired way. The meaning of data is not changed while preparing.
Modeling – In this phase the data model is created by applying certain mathematical functions and modeling techniques. After the model is created it goes through validation and verification.
Evaluation – After the model is created, it is evaluated by a team of experts to check whether it satisfies business objectives or not.
Deployment – After evaluation, the model is deployed and further plans are made for its maintenance. A properly organized report is prepared with the summary of the work done.

CSci 430: Programming Project #3
Deadlock Detection
Spring 2019
Dates:
Assigned: Monday February 25, 2019
Due: Wednesday March 13, 2019 (before Midnight)
Objectives:
ˆ Learn more about Deadlock algorithms.
ˆ Better understand how we can algorithmically detect
deadlocks on a
system.
ˆ Use C/C++ to implement vector and matrix data structures, get
prac-
tice in creating and using such data structures in C/C++.
Description:
Our textbook gives the following algorithm (pg. 276) for
algorithmically
detecting if a deadlock is present or not in a system. It requires
that the
system keep an Allocation matrix A, listing which resources are
2. currently
allocated to which processes, and the available vector V, which
gives the
amount of each resource currently available in the system. In
addition, the
deadlock detection algorithm requies a request matrix Q, which
keeps track
of the amount of each resource each process is currently
requesting from the
system. The algorithm is:
1. Mark each process that has a row in the Allocation matrix of
all zeros.
2. Initialize a temporary vector W to equal the Available vector
A.
1
3. Find an index i such that process i is currently unmarked and
the i th
row of Q is less than or equal toW. That is, Qik ≤ Wk, for 1 ≤ k
≤ m.
If no such row is found, terminate the algorithm.
4. If such a row is found, mark process i and add the
corresponding row of
the allocation matrix toW. That is, setWk = Wk+Aik, for 1 ≤ k ≤
m.
Return to step 3.
A deadlock exists if and only if there are unmarked processes at
the end
of the algorithm. Each unmarked process is deadlocked.
3. In this assignment we will implement the deadlock detection
algorithm.
Your program will be given a �le that describes the A
allocation matrix
and the Q request matrix, representing the current state of all
allocations
and requested allocations in the system. Your program will
implement the
deadlock detection algorithm described above. The result of
your program
will be one of 2 outputs:
1. If no deadlock exists, the program will display No Deadlock
on stan-
dard output.
2. If a deadlock does exist, the program will display Deadlock:
P0, P1,
P2 on standard output, where P0, P1, P2 are the processes that
the
algorithm determined to be deadlocked in the system.
State simulation �le formats
I have provided a p3-start.cpp template that can open up and
read in the
process/resource state simulation �les used for this assignment.
Here we
discuss a bit more the format of these �le. I have provided 2 or
3 exam-
ple simulations, with expected correct answers, for you to use to
test your
implementations with.
The input �les needed for this assignment need to contain the
4. information
found in theV available vector and theA allocation andQ request
matrices.
In the following I use r as the number of resources and p as the
number of
processes. Thus the general format of the input �le is:
r p
V1 V2 V3 ... Vr
A11 A12 ... A1r
...
Ap1 Ap2 ... Apr
2
Q11 Q12 ... Q1r
...
Qp1 Qp2 ... Qpr
For example, the example of the deadlock detection algorithm
given on
page 277 has a system with r=5 resources and p=4 processes.
The V, A and
Q vector/matrices are shown on that page. The input �le for the
current
state of the system shown on page 277 would be
5 4
5. 0 0 0 0 1
1 0 1 1 0
1 1 0 0 0
0 0 0 1 0
0 0 0 0 0
0 1 0 0 1
0 0 1 0 1
0 0 0 0 1
1 0 1 0 1
The function named readSystemState() in your template p2-
start.cpp
code expects a �le of this format, and reads it into a State
structure for you.
Running Simulations
The following is a discussion of the expected output of your
program. Your
program must work from the command line, and expect a single
parameter,
the name of the state simulation input �le, as its input. Your
program
should display only a single line to standard output as a result
of running it.
If the system, described in the state input �le is not deadlocked,
the program
6. should simply state there was no deadlock to standard output:
$ p3.exe state-02.sim
No Deadlock
On the other hand, if your program is deadlocked, it should say
that it
detected a deadlock, and it should print out the processes that
are deadloked
to standard output:
$ p3.exe state-01.sim
Deadlock: P0, P1,
3
I have provided 2 or 3 example input state �les, named state-
01.sim,
state-02.sim, etc. I have also provided the correct and expected
output for
these simulations, named state-01.res, state-02.out, etc.

Deadlock Detection
Spring 2019
16. Dates:
Assigned: Monday February 25, 2019
Due: Wednesday March 13, 2019 (before Midnight)
Objectives:
ˆ Learn more about Deadlock algorithms.
ˆ Better understand how we can algorithmically detect
deadlocks on a
system.
ˆ Use C/C++ to implement vector and matrix data structures, get
prac-
tice in creating and using such data structures in C/C++.
Description:
Our textbook gives the following algorithm (pg. 276) for
algorithmically
detecting if a deadlock is present or not in a system. It requires
that the
system keep an Allocation matrix A, listing which resources are
currently
allocated to which processes, and the available vector V, which
gives the
amount of each resource currently available in the system. In
addition, the
deadlock detection algorithm requies a request matrix Q, which
keeps track
of the amount of each resource each process is currently
requesting from the
system. The algorithm is:
1. Mark each process that has a row in the Allocation matrix of
17. all zeros.
2. Initialize a temporary vector W to equal the Available vector
A.
1
3. Find an index i such that process i is currently unmarked and
the i th
row of Q is less than or equal toW. That is, Qik ≤ Wk, for 1 ≤ k
≤ m.
If no such row is found, terminate the algorithm.
4. If such a row is found, mark process i and add the
corresponding row of
the allocation matrix toW. That is, setWk = Wk+Aik, for 1 ≤ k ≤
m.
Return to step 3.
A deadlock exists if and only if there are unmarked processes at
the end
of the algorithm. Each unmarked process is deadlocked.
In this assignment we will implement the deadlock detection
algorithm.
Your program will be given a �le that describes the A
allocation matrix
and the Q request matrix, representing the current state of all
allocations
and requested allocations in the system. Your program will
implement the
deadlock detection algorithm described above. The result of
your program
will be one of 2 outputs:
18. 1. If no deadlock exists, the program will display No Deadlock
on stan-
dard output.
2. If a deadlock does exist, the program will display Deadlock:
P0, P1,
P2 on standard output, where P0, P1, P2 are the processes that
the
algorithm determined to be deadlocked in the system.
State simulation �le formats
I have provided a p3-start.cpp template that can open up and
read in the
process/resource state simulation �les used for this assignment.
Here we
discuss a bit more the format of these �le. I have provided 2 or
3 exam-
ple simulations, with expected correct answers, for you to use to
test your
implementations with.
The input �les needed for this assignment need to contain the
information
found in theV available vector and theA allocation andQ request
matrices.
In the following I use r as the number of resources and p as the
number of
processes. Thus the general format of the input �le is:
r p
V1 V2 V3 ... Vr
A11 A12 ... A1r
19. ...
Ap1 Ap2 ... Apr
2
Q11 Q12 ... Q1r
...
Qp1 Qp2 ... Qpr
For example, the example of the deadlock detection algorithm
given on
page 277 has a system with r=5 resources and p=4 processes.
The V, A and
Q vector/matrices are shown on that page. The input �le for the
current
state of the system shown on page 277 would be
5 4
0 0 0 0 1
1 0 1 1 0
1 1 0 0 0
0 0 0 1 0
0 0 0 0 0
0 1 0 0 1
20. 0 0 1 0 1
0 0 0 0 1
1 0 1 0 1
The function named readSystemState() in your template p2-
start.cpp
code expects a �le of this format, and reads it into a State
structure for you.
Running Simulations
The following is a discussion of the expected output of your
program. Your
program must work from the command line, and expect a single
parameter,
the name of the state simulation input �le, as its input. Your
program
should display only a single line to standard output as a result
of running it.
If the system, described in the state input �le is not deadlocked,
the program
should simply state there was no deadlock to standard output:
$ p3.exe state-02.sim
No Deadlock
On the other hand, if your program is deadlocked, it should say
that it
detected a deadlock, and it should print out the processes that
are deadloked
to standard output:
21. $ p3.exe state-01.sim
Deadlock: P0, P1,
3
I have provided 2 or 3 example input state �les, named state-
01.sim,
state-02.sim, etc. I have also provided the correct and expected
output for
these simulations, named state-01.res, state-02.out, etc.
