Subject: [OMPI users] Issue with : btl_openib.c (OMPI 1.4.3)
From: Gilbert Grosdidier (Gilbert.Grosdidier_at_[hidden])
Date: 2010-12-15 02:59:42


  Running with OpenMPI 1.4.3 on an SGI Altix cluster with 2048 cores, I got
this error message on all cores, right at startup :

btl_openib.c:211:adjust_cq] cannot resize completion queue, error: 12

  What could be the culprit please ?
Is there a workaround ?
What parameter is to be tuned ?

  Thanks in advance for any help, Best, G.
