Communication Bandwidth of Parallel Programming Models on Hybrid Architectures

Tying Memory Management to Parallel Programming Models

Stand-alone threading libraries lack sophisticated memory management techniques. In this paper, we present a methodology that allows threading libraries that implement non-preemptive parallel programming models to reduce their memory requirements, based on the properties of those models. We applied the methodology to NthLib, which is an implementation of the Nano-Threads programming model, and ...

Evaluating Parallel Logic Programming

Parallel logic programming systems are sophisticated examples of symbolic computing systems. They address problems such as dynamic memory allocation, scheduling irregular execution patterns, and managing diierent types of implicit parallelism. Most parallel logic programming systems have been developed for bus-based shared-memory architectures. The complexity of parallel logic programming syste...

A Comparison Of Shared Memory Parallel Programming Models

The dominant parallel programming models for shared memory computers, Pthreads and OpenMP, are both thread-centric in that they are based on explicit management of tasks and enforce data dependencies and output ordering through task management. By comparison, the Cray XMT programming model is data-centric where the primary concern of the programmer is managing data dependencies, allowing thread...

GPU-STREAM v2.0: Benchmarking the Achievable Memory Bandwidth of Many-Core Processors Across Diverse Parallel Programming Models

Many scientific codes consist of memory bandwidth bound kernels — the dominating factor of the runtime is the speed at which data can be loaded from memory into the Arithmetic Logic Units, before results are written back to memory. One major advantage of many-core devices such as General Purpose Graphics Processing Units (GPGPUs) and the Intel Xeon Phi is their focus on providing increased memo...
