Lightweight cross-language pseudo-profiling for C, C++, and Python reporting timing [wall, user, system, cpu, %cpu] and resident set size (RSS) memory [current page allocation and peak usage]. These interpreters are common installations on most flavors of Unix and macOS. Open MPI is not supported under windows, but you can use cygwin and install the openmpi packages. In keeping with the general deisgn goals of the multlib support in Open MPI, extending the wrapper compilers to be multi-lib aware should be done with the following points in mind: Any multi-lib implementation should be able to cope with not just 32/64 bit builds but different processor architectures and (one day) 128 bit builds. Intel MPI tends to the most optimized while Open-MPI delivered the best performance of the open-source implementations because they have a well-optimized PSM2-based back-end. For example, if the process wishes to send one integer to another, it would use a count of one and a datatype of MPI_INT. MPICH is a high performance and widely portable implementation of the Message Passing Interface (MPI) standard. Ejemplos basicos MPI john alexander sanabria ordonez. 10 (retired) v1.
