Intel MPI Library Troubleshooting Guide

Gergana_S_Intel — Mon, 27 Jul 2015 21:47:58 GMT

The latest versions of the Intel MPI Library User's Guides have added an expanded Troubleshooting section. It provides the following information:

General Intel MPI Library troubleshooting practices
Typical MPI failures with corresponding output messages and behavior when a failure occurs
Recommendations on potential root causes and solutions

Here are direct links to these new sections:

Intel MPI Library User's Guide: Troubleshooting on Linux*
Intel MPI Library User's Guide: Troubleshooting on Windows*

We recommend taking a look there first if you're experiencing issues with the library. PDF versions of the User's Guide are also shipped with the lntel MPI Library install package, under the documentation_2016/ directory.

I am trying to launch an old c program developed for the intel / 860 but I do not know if there could be the MPI equivalent of the following functions:
crecv
gxsum
gsendx
irec
isend
msgcancel
msgwait

Hi Juan,

Hi Juan,

I'm not familiar with all the functions you list here but I can infer, based on their names, that quite a few of them would have MPI equivalents. Some of the basic MPI functions are:

MPI_Send: send a message from one process to another
MPI_Recv: receive a message from another process
MPI_Wait: wait on a particular message to be received before continuing with the rest of execution
and many others

I would recommend checking out the Lawrence Livermore National Lab MPI tutorial, if you want to get more familiar with programming using MPI.

Regards,
