I moved from Intel MPI 2018 Update 4 to Intel MPI 2019 Update 3 and it seems that the new version ignores setting the user authorization method for mpirun via environment variable I_MPI_AUTH_METHOD=delegate . Setting it directly with mpiexec -delegate still works fine. Can anyone confirm that?
Thanks and kind regards,
Thank you for finding this issue. For some reason I_MPI_AUTH_METHOD variable was not migrated to Intel MPI 2019. This variable will be available in Intel MPI 2019 Update 4.
This variable works only on Windows.
But you will still see that warning message. I will turn off it in the next release.
You can disable this warning by setting I_MPI_VAR_CHECK_SPELLING=0 variable.
