Final report
This document discusses and compares different hardware data prefetching mechanisms and their impact on performance. It covers four main types of prefetching techniques: stream buffer, stride prefetchers based on program counter or cache block address, and locality-based prefetchers. For each technique, it describes the basic algorithm, hardware requirements, advantages and disadvantages. It provides detailed explanations of how stream buffers, stride prefetchers using a reference prediction table, and address-based stride prediction work. It also outlines the design of a locality-based stream prefetcher that dynamically adjusts prefetch degree and distance based on feedback.
Prescriptive Topology Daemon - ptmd
Operator error is one of the biggest causes for network failure. In the data center, topologies based on CLOS tree and its variants, right cabling is a skilled and time consuming endeavor. PTMD is designed to take the pain and skill out of this task. PTMD runs on all routers/switches in the network (and can run on hosts too). It takes a graphviz-DOT specified network cabling plan (something many operators already generate) and couples it with with runtime information derived from LLDP to verify that the cabling matches the specification. This is done on every link transition.

A Performance Comparison of TCP Protocols
The performance of wireless ad hoc networks is impacted significantly by the way TCP reacts to lost packets. TCP was designed specifically for wired, reliable networks; thus, any packet loss is attributed to congestion in the network. This assumption does not hold in wireless networks as most packet loss is due to link failure. In our research we analyzed several implementations of TCP, including TCP Vegas, TCP Feedback, and SACK TCP, by measuring throughput, retransmissions, and duplicate acknowledgements through simulation with ns-2. We discovered that TCP throughput is related to the number of hops in the path, and thus depends on the performance of the underlying routing protocol, which was DSR in our research.
An Offline Hybrid IGP/MPLS Traffic Engineering Approach under LSP Constraints
This document proposes a novel hybrid IGP/MPLS traffic engineering method based on genetic algorithms to handle long or medium-term traffic variations.

Results comparing this hybrid approach to pure IGP routing and full mesh MPLS with and without flow splitting on the German scientific network and other networks are presented.

This document discusses parallel programming languages, including Fortran 90 and Sequent C. It provides an overview of parallel programming concepts like multicomputers, multiprocessors, and uniform memory access. It also gives examples of calculating variance and integration in parallel and describes language features for parallel programming like process creation, communication, and synchronization using barriers and mutual exclusion.
Parallel computation
Parallel computing uses multiple processors simultaneously to solve computational problems faster. It allows solving larger problems or more problems in less time. Shared memory parallel programming with tools like OpenMP and pthreads is used for multicore processors that share memory. Distributed memory parallel programming with MPI is used for large clusters with separate processor memories. GPU programming with CUDA is also widely used to leverage graphics hardware for parallel tasks like SIMD. The key challenges in parallel programming are load balancing, communication overhead, and synchronization between processors.
Transport layer udp and tcp network
The document discusses transport layer protocols UDP and TCP. It provides details on their key differences:
- UDP is a connectionless protocol that does not guarantee delivery or order of packets. It has lower overhead and is faster than TCP.
- TCP is connection-oriented and provides reliable, ordered delivery of packets through acknowledgements and retransmissions. It has higher overhead due to these reliability features.
- Both protocols operate at the transport layer, providing process-to-process communication on top of IP's host-to-host delivery. TCP uses handshaking and flow control to establish and manage connections.
Sliding window protocol
A sliding window protocol allows for reliable packet transmission over data links by assigning each packet a sequence number, tracking acknowledged packets, and allowing a limited number of unacknowledged packets to be transmitted at a time. It provides reliability through mechanisms like resending lost packets, while avoiding issues like unlimited sequence numbers by capping the number of unacknowledged transmittable packets with a window size. This sliding window approach balances reliability with throughput.
Parallel Algorithms
The document discusses parallel algorithms and their analysis. It introduces a simple parallel algorithm for adding n numbers using log n steps. Parallel algorithms are analyzed based on their time complexity, processor complexity, and work complexity. For adding n numbers in parallel, the time complexity is O(log n), processor complexity is O(n), and work complexity is O(n log n). The document also discusses models of parallel computation like PRAM and designs of parallel architectures like meshes and hypercubes.
Parallel Algorithms
The document discusses parallel algorithms and parallel computing. It begins by defining parallelism in computers as performing more than one task at the same time.

Issues in parallel programming such as task decomposition and synchronization are outlined. Performance issues like scalability and load balancing are also discussed. Different types of parallel machines and their classification are described.

3rd 3DDRESD: Red Line Overview
The document provides an overview of the Red Line system architecture, which uses a distributed intelligence concept with microprocessor boards to achieve higher efficiency and throughput in larger automation plants. The new modular architecture allows each module to work independently and in parallel for increased speeds. A workcell computer acts as a dynamic task scheduler and data logger, while the graphic user interface is Java-based for multi-user access. The document also discusses the integration of Red Line with existing IOM systems and possibilities for a hardware simulator or vision system using FPGA boards instead of microprocessor boards.
3rd 3DDRESD: SysGen
The document discusses system generation for dynamic reconfiguration in embedded systems design. It proposes a standard flow for system generation that can correctly and completely solve reconfiguration problems by characterizing the system and using the appropriate reconfiguration flow (e.g. module-based or early access partial reconfiguration).

Concurrent Replication of Parallel and Distributed Simulations
Parallel and distributed simulations enable the analysis of complex systems by concurrently exploiting the aggregate computation power and memory of clusters of execution units. In this work we investigate a new direction for increasing both the speedup of a simulation process and the utilization of computation and communication resources. Many simulation-based investigations require to collect independent observations for a correct and significant statistical analysis of results. The execution of many independent parallel or distributed simulation runs may suffer the speedup reduction due to rollbacks under the optimistic approach, and due to idle CPU times originated by synchronization and communication bottlenecks under the conservative approach. We present a parallel and distributed simulation framework supporting concurrent replication of parallel and distributed simulations (CR-PADS), as an alternative to the execution of a linear sequence of multiple parallel or distributed simulation runs. Results obtained from tests executed under variable scenarios show that speedup and resource utilization gains could be obtained by adopting the proposed replication approach in addition to the pure parallel and distributed simulation.

1.prallelism
Unit-4 discusses parallelism and techniques to exploit concurrency in computers. The goals of parallelism are to increase computational speed and throughput. There are different types of parallelism like instruction level parallelism, processor level parallelism using multiple processors, and pipelining to overlap instruction execution. Amdahl's law predicts the maximum speedup from parallel processing based on the sequential fraction of a program.
1.prallelism
The document discusses parallelism and techniques to improve computer performance through parallel execution. It describes instruction level parallelism (ILP) where multiple instructions can be executed simultaneously through techniques like pipelining and superscalar processing. It also discusses processor level parallelism using multiple processors or processor cores to concurrently execute different tasks or threads.
Pipelining in Computer System Achitecture
Parallel processing involves performing multiple tasks simultaneously to increase computational speed. It can be achieved through pipelining, where instructions are overlapped in execution, or vector/array processors where the same operation is performed on multiple data elements at once. The main types are SIMD (single instruction multiple data) and MIMD (multiple instruction multiple data). Pipelining provides higher throughput by keeping the pipeline full but requires handling dependencies between instructions to avoid hazards slowing things down.

The document discusses parallel computing platforms and trends in microprocessor architectures that enable implicit parallelism. It covers topics like pipelining, superscalar execution, limitations of memory performance, and how caches can improve effective memory latency. The key points are:
1) Microprocessor clock speeds have increased dramatically but limitations remain regarding memory latency and bandwidth. Parallelism addresses performance bottlenecks in processors, memory, and communication.
2) Techniques like pipelining and superscalar execution exploit implicit parallelism by executing multiple instructions concurrently, but dependencies and branch prediction limit performance gains.
3) Memory latency is often the bottleneck, but caches can reduce effective latency through data reuse and temporal locality.
Conference Paper: Universal Node: Towards a high-performance NFV environment
Software-Defined Networking (SDN) and Network Function Virtualization (NFV) both promise the vision of more flexible and manageable networks, but they also require certain level of programmability in the data plane.
Current industry insight holds that programmable processors (both CPUs and NPUs) are of lower performance than their hard-coded counterparts, such as Ethernet chips.
In this paper we show that Open Flow (OF) can be used for implementing various network functions, such as routing, and the performance we can get can match the non-OF implementations of the given network function once some bottlenecks are removed. Our prototype can do 100 Gbps (gigabit per second) even with small packets on one Intel blade, reaching a noticeable 110 Mpps packet speed with 64 byte long packets.

Multiple Downlink Fair Packet Scheduling Scheme in Wi-Max
IEEE 802.16 is standardization for a broadband wireless access in network metropolitan area network (MAN). IEEE 802.16
standard (Wi-Max) defines the concrete quality of service (QoS) requirement, a scheduling scheme and efficient packet scheduling
scheme which is necessary to achieve the QoS requirement. In this paper, a novel waiting queue based on downlink bandwidth
allocation architecture from a number of rtps schedule has been proposed to improve the performance of nrtPS services without any
impaction to other services. This paper proposes an efficient QoS scheduling scheme that satisfies both throughput and delay guarantee
to various real and non-real applications corresponding to different scheduling schemes for k=1,2,3,4. Simulation results show that
proposed scheduling scheme can provide a tight QoS guarantee in terms of delay for all types of traffic as defined in WiMax standards.
This process results in maintaining the fairness of allocation and helps to eliminate starvation of lower priority class services. The
authors propose a new efficient and generalized scheduling schemes for IEEE 802.16 broadband wireless access system reflecting the
delay requirements.

Vlsi design process for low power design methodology using reconfigurable fpga
Abstract
Modern digital processing applications have an increasing demand for computational power while needing to preserve low power dissipation and high flexibility. For many applications, the growth of algorithmic complexity is already faster than the growth of computational power provided by discrete general-purpose processors. A typical approach to address this problem is the combination of a processor core with dedicated accelerators. Since changes in standards or algorithms can change the demands on the accelerators, an attractive alternative to highly customized VLSI macros is suggested with the usage of reconfigurable embedded FPGAs (eFPGAs). Keyword: embedded FPGA, Fast computing, Hybrid design.
Concurrent Matrix Multiplication on Multi-core Processors
With the advent of multi-cores every processor has built-in parallel computational power and that can only be fully utilized only if the program in execution is written accordingly. This study is a part of an on-going research for designing of a new parallel programming model for multi-core architectures. In this paper we have presented a simple, highly efficient and scalable implementation of a common matrix multiplication algorithm using a newly developed parallel programming model SPC3 PM for general purpose multi-core processors. From our study it is found that matrix multiplication done concurrently on multi-cores using SPC3 PM requires much less execution time than that required using the present standard parallel programming environments like OpenMP. Our approach also shows scalability, better and uniform speedup and better utilization of available cores than that the algorithm written using standard OpenMP or similar parallel programming tools. We have tested our approach for up to 24 cores with different matrices size varying from 100 x 100 to 10000 x 10000 elements. And for all these tests our proposed approach has shown much improved performance and scalability
HIGH-LEVEL LANGUAGE EXTENSIONS FOR FAST EXECUTION OF PIPELINE-PARALLELIZED CO...
The last few years have seen multicore architectures emerge as the defining technology shaping the future
of high-performance computing. Although multicore architectures present tremendous performance
potential, to realize the true potential of these systems, software needs to play a key role. In particular,
high-level language abstractions and the compiler and the operating system should be able to exploit the
on-chip parallelism and utilize underlying hardware resources on these emerging platforms. This paper
presents a set of high-level abstractions that allow the programmer to specify, at the source-code level, a
variety to of parameters related to parallelism and inter-thread data locality. These abstractions are
implemented as extensions to both C and Fortran. We present the syntax of these directives and also
discuss their implementation in the context of source-to-source transformation framework and autotuning
system. The abstractions are particularly applicable to pipeline parallelized code. We demonstrate the
effectiveness of these strategies of a set of pipeline parallel benchmarks on three different multicore
platforms.

TiReX: Tiled Regular eXpression matching architecture
Regular Expressions (RE) are widely used to find patterns among data, like in genomic markers research for DNA analysis, deep packet inspection or signature-based detection for network intrusion detection system. This paper proposes a novel and efficient RE matching architecture for FPGAs, based on the concept of matching core. RE can be software-compiled into sequences of basic matching instructions that a matching core runs on input data, and can be replaced to change the RE to be matched. This architecture can easily scale up with the available resources and is customizable to multiple usage scenarios. We ran several experiments and compared the obtained results with a software solution, reaching speedups over 100x, while running at 130MHz, over a Flex-based matching application running on an Intel i7 CPU at 2.8GHz.
Performance comparison of row per slave and rows set
This document compares two methods for parallel matrix multiplication using PVM (Parallel Virtual Machine): the row per slave method and the rows set per slave method. It finds that the row per slave method provides optimal computation time. The row per slave method assigns each slave a single row from the first matrix to compute, while the rows set per slave method assigns each slave a set of rows. Experimental results on matrices of varying sizes show the row per slave method takes less time, with an average 50% reduction in computation time compared to the rows set per slave method.
