[empty-sub-group]
ML topology configuration explicitly requested for this subgroup:
%s
Such configuration results in a creation of empty groups. As a result, ML
framework cannot configure requested collective operations. ML framework will be
disabled. One configuration that might enable ML component is --mca bcol_base_string basesmuma,ptpcoll
--mca sbgp_base_subgroups_string basesmuma,p2p
[allreduce-not-supported]
This BCOL is configured in one of the hierarchy :
%s
The BCOL does not support Allreduce for all
operations and datatype combination. In addition, you did not suggest
alternate topology building configurations.
[allreduce-alt-nosupport]
The hierarchy is configured with alternate BCOL:
%s
Both the original topology and alternate topology not support Allreduce for all
operations and datatype combination. In addition, you did not suggest
alternate topology building configurations.
[fragmentation-disabled]
ML could not be used because the mca param coll_ml_enable_fragmentation
was set to zero and there is a bcol that does not support
zero copy method.
[static-bcast-disabled]
ML could not be used because the mca param coll_ml_bcast_algorithm
was not set to static and other broadcast implementation was available.
