What are the feature differences between MS mpiexec and Intel mpiexec?

[jimdempseyatthecove]

mpiexec exist in the Microsoft distribution and Intel distributes their version of mpiexec. Is there a writeup of the feature differences?

Hi,

Thank you for posting in Intel Communities.

Could you please let us know for what purpose(in which context) you need the comparisons?

And also can get the details of mpiexec in both Intel and MS as follows:

mpiexec -- help

Thanks and Regards,

I am not interested in the command line option differences, but rather in any performance differences provided by the different implementations. For example, Intel provided mpiexec uses Intel provided Hydra which has bla bla features as opposed to MS mpiexec that uses MS provide fabric which lacks ... capabilities.

Hello,

The last release note for MS-MPI is 2019, while Intel MPI is still being actively developed. It appears that Intel MPI has wider support for various network interfaces, as far as we know.

And currently we don't have any benchmarks available, and since Microsoft appears to have halted the development of MS-MPI, we won't be able to create any benchmarks.

Thanks And Regards,
