OpenSHMEM是单程序、多数据(single program multiple data,SPMD)编程模型,特点是强调单边通信以及数据移动与同步解藕,是提供高性能、高可扩展性通信和同步程序的库。OpenSHMEM程序由松散同步的进程组成,这些进程也叫作处理单元(Processing Element,PE)。所有PE同时开始并执行相同的程序,通常在各自集合问题的子域上执行操作,...

O_APPEND 当读写文件时会从文件尾开始移动,也就是所写入的数据会以附加的方式加入到文件后面。 O_NONBLOCK 以不可阻断的方式打开文件,也就是无论有无数据读取或等待,都会立即返回进程之中。 O_NDELAY 同O_NONBLOCK。 O_SYNC 以同步的方式打开文件。 O_NOFOLLOW 如果参数pathname 所指的文件为一符号连接,则会...
For a wide acceptance of OpenSHMEM model on GPU systems, these limitations need to be handled at the level of the programming model and their associated run-times. We proposed a CUDA-Aware OpenSHMEM [6] runtime that hides the complexity of GPU programming. The envisioned model is illustrated ...
NVSHMEMimplements theOpenSHMEMparallel programming model for clusters of NVIDIA ® GPUs. The NVSHMEM Partitioned Global Address Space (PGAS) spans the memory across GPUs and includes an API for fine-grained GPU-GPU data movement from within a CUDA kernel, on CUDA streams, and from the CPU. ...

UPC and OpenSHMEM PGAS Models on GPU Clusters May 20, 2015 by Doug Black “Learn about extensions that enable efficient use of Partitioned Global Address Space (PGAS) Models like OpenSHMEM and UPC on supercomputing clusters with NVIDIA GPUs. PGAS models are gaining attention for providing shared...
This is a major release that heralds the beginning of a new production-ready series, full MPI-3.0 support, and a new OpenSHMEM implementation. Open MPI is developed in a tick-tock fashion: Odd-numbered series are focused on feature development and expansion Even-numbered series are focused on...
