Programming with POSIX threads

David R. Butenhof · 1993

With this practical book, you will attain a solid understanding of threads and will discover how to put this powerful mode of programming to work in real-world applications.The primary advantage of threaded programming is that it enables your applications to accomplish more than one task at the same time by using the number-crunching power of multiprocessor parallelism and by automatically exploiting I/O concurrency in your even on a single processor machine. The result: applications that are faster, more responsive to users, and often easier to maintain. Threaded programming is particularly well suited to network programming where it helps alleviate the bottleneck of slow network I/O.This book offers an in-depth description of the IEEE operating system interface standard, POSIXAE (Portable Operating System Interface) threads, commonly called Pthreads. Written for experienced C programmers, but assuming no previous knowledge of threads, the book explains basic concepts such as asynchronous programming, the lifecycle of a thread, and synchronization. You then move to more advanced topics such as attributes objects, thread-specific data, and realtime scheduling. An entire chapter is devoted to real code, with a look at barriers, read/write locks, the work queue manager, and how to utilize existing libraries. In addition, the book tackles one of the thorniest problems faced by thread programmers-debugging-with valuable suggestions on how to avoid code errors and performance problems from the outset.Numerous annotated examples are used to illustrate real-world concepts. A Pthreads mini-reference and a look at future standardization are also included.

A Crossing with Java Threads and POSIX Threads

Wim H. Hesselink · 2001

The primitives for Java threads and POSIX threads are compared by means of a simulation of cars at a crossing. These cars have to be synchronized in such a way that at every moment only cars in one direction proceed. The initial solution is based on compound await statements. This

Correctly Synchronised POSIX-threads Benchmark Applications

Christos Sakalis · KTH Publication Database DiVA (KTH Royal Institute of Technology) · 2015

With the future of high performance computing quickly moving towards a higher and higher count of CPU cores, the need for efficient memory coherence models is becoming more and more prevalent. Strict memory models, while convenient for the programmer, limit the scalability and overall performance of multi- and manycore systems. For this reason, relaxed memory models are looked into, both in academia and in the industry. Applications written for stronger memory models often contain data races, which cause unexpected behaviour in more relaxed models, many of which rely on data race free code to work. At the same time, some of the most widely used programming languages now require data race free code. For these reasons, the need for benchmarks based on properly synchronised code is bigger than ever. In this thesis, we will identify data races in major benchmark suites, remove them, and then quantify and compare the performance differences between the unmodified and the properly synchronised versions.

A Parallel LLL using POSIX Threads

Werner Backes, Susanne Wetzel · 2008

In this paper we introduce a new parallel variant of the LLL lattice basis reduction algorithm. Lattice theory and in particular lattice basis reduction continues to play an integral role in cryptography. Not only does it provide effective cryptanalysis tools but it is also believed to bring about new cryptographic primitives that exhibit strong security even in the presence of quantum computers. In theory, many aspects of lattices are already well-understood. Yet, many practical aspects, like the performance of lattice basis reduction algorithms, are still under investigation. In this paper, we introduce a new parallel lattice basis reduction algorithm that overcomes shortcomings of previously introduced algorithms. First and foremost, our new algorithm is based on the Schnorr-Euchner algorithm and as such is the first—to the best of our knowledge—to provide a parallel implementation for the Schnorr-Euchner algorithm. Second, using POSIX threads allows us to make effective use of today’s multi-processor, multi-core computer architecture. Developing in a shared memory setting allows us to replace time consuming inter-process communication with synchronization points (barriers) and locks (mutexes). Our implementation of the parallel LLL is optimized for reducing high dimensional lattice bases with big entries that would require a multiprecision

Wavefront parallel processing based on POSIX threads

Jian Wang, Xin Zhou · 2016

To cope with the significant computational complexity introduced by High Efficiency Video Coding (HEVC) standard, several parallelization schemes are introduced, such as Tiles, Wavefront parallel processing(WPP) and Dependent slice segments. These coding structures make multi-core processing possible. In this paper, we analyzed the degree of parallelism WPP can achieve and then proposed a multi-threaded encoder implementation based on WPP by using POSIX Threads. Experimental results show that the speedup of parallel encoding using WPP can reach about 3.4 times on quad core processor when encoding a 1080p video sequence.

Implementing POSIX Threads under UNIX: Description Of . . .

Frank Mueller · 1992

Recently, there has been an effort to specify an IEEE standard for portable operating systems for open systems, called POSIX. One part of it, the POSIX.4a threads extension [3], describes the interface for lightweight threads that rely on shared memory and have a smaller context frame than processes. This paper describes the design and implementation of a library of POSIX.4a calls that is solely based on UNIX. It shows that a library implementation is feasible. This work can also be used as as a prototyping, testing, and debugging system in the regular UNIX environment.

Murks - A POSIX Threads Based DSM System

Markus Pizka, C. Rehn · 2001

The shared memory paradigm provides an easy to use programming model for communicating processes. Its implementation in distributed environments has proofed to be harder than expected. Most distributed shared memory (DSM) systems suffer from either poor performance or they are very complicated to use. The DSM system Murks, presented in this paper, is the result of the sobering experiences we made by trying to integrate an existing DSM system into a distributed OS. Murks distinctive

OpenMP and POSIX threads implementation of Jerasure 2.0

Şuayb S. Arslan, Hoa Le, Joseph Landman et al. · 2017

In shared memory multiprocessor architectures, threads can be used to implement parallelism. POSIX threads (pthreads) is a low-level bare-bones programming interface for working with threads. Therefore, we have extremely fine-grained control over thread management (create/join/etc), mutexes, and so on. On the other hand, openMP, as a shared-memory standard, is much higher level and portable interface which makes it easier to use multi-threading capability and obtain satisfactory performance improvements. Since pthreads is more flexible, it helps programmers gain more control on performance optimizations. Jerasure 2.0 erasure coding library has encoding/decoding engines which comprise independent “for” loop iterations and hence possess huge potential for multi-threaded processing. In this short paper, we investigate multi-threaded implementations of encoder/decoder pair of Jerasure 2.0 using two different technologies: OpenMP and pthreads. We constrain our changes to a minimum possible and compare the pure encoding/decoding performance with respect to each other as well as against that of the original single-threaded version by running them on two different server systems.

A User-level Checkpointing Library for POSIX Threads Programs

William Dieter James, James E. Lumpp Jr · 1999

Several user-level checkpointing libraries that checkpoint Unix processes have been developed. However, they do not support multithreaded programs. This paper describes a user-level checkpointing library to checkpoint multithreaded programs that use the POSIX threads library provided by Solaris 2. Experiments with programs from the SPLASH-2 benchmark suite showed a 3% to 10% increase in execution time with checkpointing enabled, plus an additional overhead for saving the program's state. The checkpointing library described here is available at http://www.dcs.uky.edu/chkpt/. 1. Introduction A multithreaded program's state can be divided into private state and shared state. A thread's private state includes its program counter, stack pointer, and registers. Its shared state includes everything common to all threads in the process, such as the address space and open file state. A multithreaded checkpointing library must save and recover the program's shared state and each thread's priva...

Implementing Ada 9X features using POSIX Threads: Design Issues

E. W. Giering, Frank Mueller, Frank Mueller et al. · 1993

The draft standard POSIX Threads Extension provides an application program interface to operating system services supporting the creation and execution of multiple threads of control within a single process. Where Ada is implemented over an operating system that supports POSIX-like thread services, there are good reasons to implement the Ada tasks as POSIX threads. This paper explores some of the design issues involved in implementing Ada 9X tasking constructs on a system supporting POSIX threads. 1 Introduction We are developing a runtime system (RTS) library to support Ada 9X tasking. To enhance portability, this RTS is being designed to be able to use standard interfaces for operating system services. It will use a set of low-level primitives that can either be implemented directly on a bare machine, or mapped onto the services of an operating system that supports multiple threads of control within a single address space. The first such OS interface to be targeted is the POSIX 1003....

ACT++ 3.0: implementation of the actor model using POSIX threads

Arjun Khare · VTechWorks (Virginia Tech) · 1994

The actor model provides a framework for writing concurrent programs. ACT ++ is an implementation of the actor model in C++, allowing concurrent programs to be written in an object-oriented style. In ACT++, each actor is an object possessing one or more independent threads of control. Version 2.0 of ACT ++ uses the PRESTO threads package. As PRESTO threads are available only for certain architectures and operating systems, its use does not meet one of the goals of ACT ++, namely portability among a variety of architectures. To facilitate portability, ACT++ 3.0 is written using the IEEE POSIX 1003.4a standard for threads (Pthreads). This project deals with the implementation of ACT++ 3.0, the testing of the implementation, and its performance.
