How to use Intel MPI 5.0?

How to use Intel MPI 5.0?

Dear all,

I noticed that Intel has release Intel MPI 5.0 and I downloaded latest version to test it. The command I used is as follows (it works with latest Intel MPI 4.1.x):

mpiexec -wdir D:\Users\tang\Debug -mapall -hosts 1 n01 1 D:\Users\tang\Debug\fem

However, the following error messages displayed:

[mpiexec@tangDELL] ..\hydra\utils\args\args.c (255): unrecognized argument mapall
[mpiexec@tangDELL] ..\hydra\utils\args\args.c (270): argument matching returned error
[mpiexec@tangDELL] parse_args (..\hydra\ui\mpich\utils.c:3279): error parsing input array
[mpiexec@tangDELL] HYD_uii_mpx_get_parameters (..\hydra\ui\mpich\utils.c:3554): unable to parse user arguments
[mpiexec@tangDELL] ..\hydra\ui\mpich\mpiexec.c (438): error parsing parameters


Is there anything I missed to use latest MPI?

For more complete information about compiler optimizations, see our Optimization Notice.

The -mapall option is only used for SMPD managed jobs.  We do not have an equivalent option in Hydra, and mpiexec now defaults to using Hydra.  If you want to use SMPD, run mpiexec.smpd instead.
