Description Mathis Clayer 2021-04-29 08:45:35 MDT 
Hello,
Is it possible to provide the support for pmix v4 ? There are some minor changes to be done in order to build Slurm with this version of pmix:

Inside: auxdir/x_ac_pmix.m4:

   AM_CONDITIONAL(HAVE_PMIX, [test $_x_ac_pmix_v1_found = "1"] ||
                 [test $_x_ac_pmix_v2_found = "1"] ||
-                [test $_x_ac_pmix_v3_found = "1"] )
+                [test $_x_ac_pmix_v3_found = "1"] ||
+                [test $_x_ac_pmix_v4_found = "1"] )
   AM_CONDITIONAL(HAVE_PMIX_V1, [test $_x_ac_pmix_v1_found = "1"])
   AM_CONDITIONAL(HAVE_PMIX_V2, [test $_x_ac_pmix_v2_found = "1"])
   AM_CONDITIONAL(HAVE_PMIX_V3, [test $_x_ac_pmix_v3_found = "1"])


Inside src/plugins/pmi/pmix/mpi_mpix.c:

 const char plugin_type[] = "mpi/pmix_v2";
 #elif (HAVE_PMIX_VER == 3)
 const char plugin_type[] = "mpi/pmix_v3";
+#elif (HAVE_PMIX_VER == 4)
+const char plugin_type[] = "mpi/pmix_v4";
 #endif
 
I hope I didn't forget any change to support pmix_v4.

Best regards,
Mathis.

Hi Matis,

Thanks for your report. We are tracking this issue in bug 7263 but pmix/v4 is not supported yet. This bug is open so you can read through it if you are interested, but briefly there are some functions that need to be added to our api to support this.

I am marking this issue as a dup of 7263.
