command not recognized when setting up Intel MPI Library

[zhzhu1218]

Hello,

I used to work with MPI codes using Intel Parallel Studio + VS 2019 + Fortran, and just updated to openAPI + VS 2022 + Fortran. When following the guide here (https://www.intel.com/content/www/us/en/docs/mpi-library/get-started-guide-windows/2021-6/overview.html) to set up the updated Intel MPI Library, I get through the first two steps (hydra_service -install; hydra_service -start). But when I key in mpiexec -register, the command prompt pops out '-register' is not recognized as an internal or external command, operable program, or batch file.

Am I making a silly mistake here?

Thanks!

In case helpful, here is what I'm seeing on my command prompt

Hi Zhengren, please share the below information with us:

- OS build on which you are installing the software

- Is the installer an online or an offline package?

- Version of Microsoft Visual Studio installed along with it's build version

- Other versions of Intel® Parallel Studio XE or Intel® oneAPI already installed on the system

- Screenshots of the error screen

- Installation Log files.

The default path for a log file for a oneAPI installation is: C:\Program Files (x86)\Intel\oneAPI\logs

The default path for a log file for a Parallel Studio XE installation is: %temp%\pset_tmp_PSXE<version>_<username>

We would like to know.

Thanks for the response Arpan! Here are the info:

- Microsoft Windows 10

- Online installer

- VS 2022, 17.6.2

- oneAPI base toolkit and oneAPI HPC. Both the latest version (installed this week). I used to use the MPI library from Intel Parallel Studio XE, but have uninstalled it before installing oneAPI

- The error is as shown in the second half of this image when I try to register mpiexec here:

- Attached the log files here

Hi,

Password-based authentication, as well as all the related options (-register in particular), are removed in the Intel MPI 2021.9 release.

The user authentication process has changed, hydra_service is only necessary for domain-based authentication, refer to the manual for details.

https://www.intel.com/content/www/us/en/developer/articles/release-notes/mpi-library-release-notes-windows.html

Also, you may find in our prerequisite steps that there is no need to install the service unless domain-based authentication is used

https://www.intel.com/content/www/us/en/docs/mpi-library/developer-guide-windows/2021-6/prerequisite-steps.html

Basically, we may recommend just installing and running IMPI without any extra prerequisite steps.

Thanks & Regards
