Therefore, the Message Passing Interface (MPI), which is the most common parallel programming system for HPC applications, must enable these advanced approaches. Even if the existing MPI Profiling Interface, PMPI, provides comprehensive tool support, it is no longer sufficient to enable these ...

We present a simple library which equips MPI implementations with truly asynchronous non-blocking point-to-point operations, and which is independent of the underlying communication infrastructure. It utilizes the MPI profiling interface (PMPI) and the MPI_THREAD_MULTIPLE thread compatibility level, and...
This allows the simple use of libraries that make use of the MPI profiling interface and that are installed in the same directory as the MPI library. If name.conf is the name of a file in the sysconfdir directory, then this is read and may define the following variables: PROFILE_PRELIB ...
使用mpi4py 的 profiling 功能 mpi4py 的 profiling 功能需要有 PAPI (Performance Application Programming Interface) 的支持,前往http://icl.cs.utk.edu/papi/software/index.html下载并安装 PAPI。 较早的 mpi4py 软件由于一些编译选项设置不合理导致 mpi4py 程序在加上 profiling 语句后不生成日志文件(程序可...
This library provides a simplistic tracing of select MPI function calls via the MPI profiling interface. Linking it in to your application via (e.g., via -lompitrace) will automatically output to stderr when some MPI functions are invoked: shell$ cd examples/ shell$ mpicc hello_c.c -o ...
Other Tools To collect application traces and analyze the performance of MPI applications, well established and much more sophisticated tools likeScore-P,VampirorTAUexists. These tools use our profiling interface CUPTI to assess MPI+CUDA applications and also offer advanced support to detect MPI and ...
