[gpfsug-discuss] verbsPortsOutOfOrder

[Simon Thompson]

Thanks Tomer.

That makes sense, also not something I think we need to worry about – I assume that relates to hypercube or dragonfly or some such though the Mellanox docs only say “some topologies”

Simon,

It looks like its setting the Out Of Order MLX5 environmental parameter:

Hi,

In mmdiag --config, we see “verbsPortsOutOfOrder” as an unset option. Could anyone comment on what that might do and if it relates to the ordering that “verbsPorts” are set?

Thanks
