Intel MPI Library Troubleshooting Guide

[Gergana_S_Intel]

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,

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.
