[mvapich-discuss] cm_enable_qp_init_to_rtr error

[Sayantan Sur]

Hi Steve,

Thanks for your report. This may be related to the on-demand
connection manager in MVAPICH. It could also be some weird IB stack
issue where connection creation fails sometimes. It will be hard to
say which way without more details about the system and the workload
you are running:

1) Which version of OFED are you running? what is your platform?
2) At how many processes do you see this failure?
3) Can the application code be tried out by others to see if they
reproduce this error?
4) Do you see this failure with any other compilers, or is it specific to icc?

Hopefully, with this information we will better understand your problem.

Thanks.
