Modes of transfer - Computer Organization & Architecture - Nithiyapriya Pasav...priya Nithya
The document discusses three modes of data transfer between the central processing unit (CPU) and input/output (I/O) devices: programmed I/O, interrupt-initiated I/O, and direct memory access (DMA). Programmed I/O requires the CPU to continuously monitor the I/O device for data readiness, slowing performance. Interrupt-initiated I/O allows the I/O device to generate interrupts when ready, pausing the CPU to service transfers. DMA bypasses the CPU by allowing direct memory access between I/O devices and memory, speeding large data transfers.
This document provides an introduction to multiprocessor systems. It describes how multiprocessor systems use multiple processors together to improve performance and speed over uniprocessor systems. Multiprocessor systems can be tightly or loosely coupled. Tightly coupled systems share memory and communication while loosely coupled systems use separate processors connected via a network. The document discusses different interconnection techniques for multiprocessors like bus-oriented, crossbar, and multistage switching systems. It also covers multiprocessor operating systems and their functions in supporting parallel processing across CPUs.

Deadlocks-An Unconditional Waiting Situation in Operating System. We must make sure of This concept well before understanding deep in to Operating System. This PPT will understands you to get how the deadlocks Occur and how can we Detect, avoid and Prevent the deadlocks in Operating Systems.
CPU scheduling allows processes to share the CPU by pausing execution of some processes to allow others to run. The scheduler selects which process in memory runs on the CPU. There are four types of scheduling decisions: when a process pauses for I/O, switches from running to ready, finishes I/O, or terminates. Scheduling can be preemptive, where a higher priority process interrupts a running one, or non-preemptive. Common algorithms are first come first serve, shortest job first, priority, and round robin. Real-time scheduling aims to process data without delays and ensures the highest priority tasks run first.
Process scheduling involves assigning system resources like CPU time to processes. There are three levels of scheduling - long, medium, and short term. The goals of scheduling are to minimize turnaround time, waiting time, and response time for users while maximizing throughput, CPU utilization, and fairness for the system. Common scheduling algorithms include first come first served, priority scheduling, shortest job first, round robin, and multilevel queue scheduling. Newer algorithms like fair share scheduling and lottery scheduling aim to prevent starvation.
Direct memory access (DMA) allows certain hardware subsystems to access computer memory independently of the central processing unit (CPU). During DMA transfer, the CPU is idle while an I/O device reads from or writes directly to memory using a DMA controller. This improves data transfer speeds as the CPU does not need to manage each memory access and can perform other tasks. DMA is useful when CPU cannot keep up with data transfer speeds or needs to work while waiting for a slow I/O operation to complete.
Direct Memory Access (DMA) allows for the direct transfer of data between memory and I/O devices without intervention from the CPU. A DMA controller handles the transfer, freeing up the CPU to perform other tasks. The DMA controller connects the I/O device, memory, and system buses, initiating transfers when instructed by the CPU and notifying the CPU upon completion through interrupts. This improves system performance by bypassing the CPU for large data transfers between memory and I/O.
Round Robin is a preemptive scheduling algorithm where each process is allocated an equal time slot or time quantum to execute before being preempted. It is designed for time-sharing to ensure all processes are given a fair share of CPU time without starvation. The process is added to the back of the ready queue when its time slice expires. It provides low response time on average but increased context switching overhead compared to non-preemptive algorithms. The time quantum value impacts both processor utilization and response time.
1) A semaphore consists of a counter, a waiting list, and wait() and signal() methods. Wait() decrements the counter and blocks if it becomes negative, while signal() increments the counter and resumes a blocked process if the counter becomes positive.
2) The dining philosophers problem is solved using semaphores to lock access to shared chopsticks, with one philosopher designated as a "weirdo" to avoid deadlock by acquiring locks in a different order.
3) The producer-consumer problem uses three semaphores - one to limit buffer size, one for empty slots, and one for locks - to coordinate producers adding to a bounded buffer

Spooling and buffering are techniques used in operating systems to improve performance. Spooling overlaps the input of one job with the computation of other jobs using a disk as a buffer between programs and input/output devices. Buffering stores data temporarily in memory during input and output to allow the CPU and I/O devices to work more efficiently by overlapping their activities. This increases overall system performance.
The document discusses the history and generations of operating systems. It begins by defining an operating system and its basic functions. It then outlines the four generations of operating systems: 1) First generation (1945-1955) used vacuum tubes and mechanical relays with no programming languages or operating systems; 2) Second generation (1955-1965) introduced transistors, batch processing, and magnetic tapes; 3) Third generation (1965-1980) used integrated circuits, introduced timesharing through multiprogramming, and combined commercial and scientific systems; 4) Fourth generation (1980-present) saw the rise of personal computers powered by microchips leading to networks and distributed systems.
Each process in an operating system is represented by a Process Control Block (PCB). The PCB is a data structure that contains information needed to manage a particular process, and serves as the manifestation of a process in the OS. A PCB consists of pointers, process state, program counter, CPU registers, CPU scheduling information, memory management information, accounting information, and I/O status information. This information allows the OS to control, schedule, and terminate processes.

This document discusses various techniques for process synchronization. It begins by defining process synchronization as coordinating access to shared resources between processes to maintain data consistency. It then discusses critical sections, where shared data is accessed, and solutions like Peterson's algorithm and semaphores to ensure only one process accesses the critical section at a time. Semaphores use wait and signal operations on a shared integer variable to synchronize processes. The document covers binary and counting semaphores and provides an example of their use.
1) Data transfer instructions move data between processor registers and memory without changing the data. Common instructions include load, store, move, exchange, input, and output.
2) Data manipulation instructions perform arithmetic, logical, and bitwise operations on data to provide computational capabilities. Examples include add, subtract, multiply, divide, and, or, xor.
3) Program control instructions alter the program flow by branching, jumping, calling subroutines, handling interrupts, and returning from subroutines. Status bits track results of operations.
Mobile databases allow data to be accessed from mobile devices connected over mobile networks. They replicate and synchronize data with centralized database servers. Key features include communicating with centralized servers wirelessly, managing data locally on mobile devices, and creating customized mobile apps. Popular mobile database management systems include SQLite, SQL Anywhere, and DB2 Everyplace. Choosing a suitable mobile DB requires considering factors like memory footprint, security, operating system support, and handling disconnections.
This document discusses deadlock prevention by invalidating one of the four conditions necessary for deadlock: mutual exclusion, hold and wait, no preemption, and circular wait. It describes strategies to prevent each condition, such as not requiring mutual exclusion for sharable resources, requesting all resources before execution or only when a process has none to prevent hold and wait, allowing preemption of held resources to prevent no preemption, and imposing a total ordering of resource requests to prevent circular wait. These techniques aim to ensure deadlock is excluded from the beginning.

Factors influencing the success of computer architectureMajane Padua
This document discusses factors that influence the success of computer architecture. It outlines architectural merit, open/closed architecture, system performance, and system cost as key factors. Architectural merit is measured by applicability, efficiency, malleability, expandability, and compatibility. Open architecture allows third parties to add components, while closed architecture does not. System performance depends on the processor, RAM, disk, video card, and benchmarks are used to measure performance.
Our new product (Clicktale Experience cloud) requires processing up to half a million messages per second, sessionizing each "users" journey throughout a web page. In this talk we'll discuss how we have achieved that using Spark's stateful streaming capabilities with only few servers in production, the challenges we've faced and how we've solved them. We'll also take a look at Spark 2.2 (the brand new version) and its new stateful aggregation and talk about how we've used it in order to improve performance significantly.
This presentation introduces how we design and implement a real-time processing platform using latest Spark Structured Streaming framework to intelligently transform the production lines in the manufacturing industry. In the traditional production line there are a variety of isolated structured, semi-structured and unstructured data, such as sensor data, machine screen output, log output, database records etc. There are two main data scenarios: 1) Picture and video data with low frequency but a large amount; 2) Continuous data with high frequency. They are not a large amount of data per unit. However the total amount of them is very large, such as vibration data used to detect the quality of the equipment. These data have the characteristics of streaming data: real-time, volatile, burst, disorder and infinity. Making effective real-time decisions to retrieve values from these data is critical to smart manufacturing. The latest Spark Structured Streaming framework greatly lowers the bar for building highly scalable and fault-tolerant streaming applications. Thanks to the Spark we are able to build a low-latency, high-throughput and reliable operation system involving data acquisition, transmission, analysis and storage. The actual user case proved that the system meets the needs of real-time decision-making. The system greatly enhance the production process of predictive fault repair and production line material tracking efficiency, and can reduce about half of the labor force for the production lines.
This document discusses monitoring servers with openSUSE Leap. It introduces server monitoring basics like why it is important and what aspects to monitor such as CPU, RAM, and hard disk usage.

Immutable infrastructure isn’t the answerSam Bashton
Immutable infrastructure wasn't suitable for the consultancy's needs as it led to long deployment times and a lack of visibility into instance configurations. Instead, they developed a hybrid approach using Packer, Puppet, S3, and AWS services that provides faster deployments, self-healing infrastructure, and a known, verifiable state for instances. This allows them to focus on application development rather than infrastructure management.
Data analytics in the cloud with Jupyter notebooks.Graham Dumpleton
Jupyter Notebooks provide an interactive computational environment, in which you can combine Python code, rich text, mathematics, plots and rich media. It provides a convenient way for data analysts to explore, capture and share their research.
Numerous options exist for working with Jupyter Notebooks, including running a Jupyter Notebook instance locally or by using a Jupyter Notebook hosting service.
This talk will provide a quick tour of some of the more well known options available for running Jupyter Notebooks. It will then look at custom options for hosting Jupyter Notebooks yourself using public or private cloud infrastructure.
An in-depth look at how you can run Jupyter Notebooks in OpenShift will be presented. This will cover how you can directly deploy a Jupyter Notebook server image, as well as how you can use Source-to-Image (S2I) to create a custom application for your requirements by combining an existing Jupyter Notebook server image with your own notebooks, additional code and research data.
Specific use cases around Jupyter Notebooks which will be explored will include individual use, team use within an organisation, and class room environments for teaching. Other issues which will be covered include importing of notebooks and data into an environment, storing data using persistent volumes and other forms of centralised storage.
As an example of the possibilities of using Jupyter Notebooks with a cloud, it will be shown how you can easily use OpenShift to set up a distributed parallel computing cluster using ‘ipyparallel’ and use it in conjunction with a Jupyter Notebook.

2. Spooling
• SPOOL - Simultaneous Peripheral Operation
On- Line.
• Spooling overlaps input of one job with the
computation of other job.
3. How Spooling Works
• It involves a secondary memory which is used to hold
data till the device is ready to operate on this data.
• When device get ready the data is loaded onto main
memory for required operations.

When Operating Systems were being built, CPUs executed instructions to give us output based on the input we provided, however, I/O operations took more time than CPU took to execute them. So, CPUs had to be put into an idle state till the instruction is processed by the I/O device and then the output is shown. After this another process will start . From this we can understand that the CPU was most of the time idle, which is the worst condition that we can have in Operating Systems. Here, the concept of Spooling comes into play.
so, This allow more I/O operation to be carried out simultaneously and enable us to experience faster applications of our peripheral devices.
Lets take and interesting example that we have all experienced. When your operating system hangs for any particular reason or your keyboard stops working while you are typing, have you noticed how all the alphabets that you pressed after the system hung suddenly get typed out very fast on their own even though you are not typing anymore. So, how this is working.
Lets see the inner working of it with the help of spooling in printer.
Read ppt.
The documents which are to be printed are stored in the secondary memory and then added to the queue for printing. During this time, many processes can perform their operations and use the CPU without waiting while the printer executes the printing process on the documents one-by-one.
After the CPU generates some output, this output is first saved in the main memory. This output is transferred to the secondary memory from the main memory, and from there, the output is sent to the printer.
The number of operations does not matter. Many I/O devices can work together simultaneously without any disruption to each other.
Less interaction is needed between the I/O devices and the CPU. That means there is no need for the CPU to wait for the I/O operations to take place because these operations take more time to finish executing, so the CPU will not wait for them to finish.
When there was no spooling process, CPU used to be in idle state at the time of input and output which is not considered very efficient. So spooling keep the CPU busy most of the time and only goes to the idle state when the queue is exhausted. So, all the tasks are added to the queue, and the CPU will finish all those tasks and then go into the idle state.
It allows applications to run at the speed of the CPU while operating the I/O devices at their respective full speeds.
Spooling requires a large amount of storage depending on the number of requests made by the input and the number of input devices connected.
If many input devices work simultaneously, they may take up a lot of space on the secondary memory and thus increase disk traffic. This results in the disk getting slower and slower as the traffic will increase.
Spooling is used for copying and executing data from a slower device to a faster device. This process in itself makes Spooling ineffective to use in real-time environments where we need real-time results from the CPU. This is because the input device is slower and thus produces its data at a slower pace while the CPU can operate faster, so it moves on to the next process in the queue. This is why the final result or output is produced at a later time instead of in real-time.
