There are no errors visible in the error counters in any of the HCAs
or
switches or anywhere else.
I'm running OMPI 1.3.2 built with pathscale 3.2
If i add -mca btl 'ofud,self,sm' the same code works ok.
Interesting. I have only done very limited testing with ofud; are you
saying that you get these errors if you "--mca btl openib,sm,self"?
It usually only shows up on runs with nodes=16:ppn=8 or higher, i.e.
8x8
works ok.
This might very well be a pathscale problem since when running with
the
debug version of ompi 1.3.2 the problem goes away.
Complete error is:
error polling LP CQ with status RECEIVER NOT READY RETRY EXCEEDED
ERROR
status number 13 for wr_id 465284992 opcode -1 vendor error 135
qp_idx
0
Any ideas to where in the ompi code i should start reducing
optimization
levels to pinpoint this?
Do you have a simple reproducer test case, perchance?
