Subject: [OMPI users] Use of -mca pml csum
From: Gilbert Grosdidier (Gilbert.Grosdidier_at_[hidden])
Date: 2010-12-14 04:55:24


  Since I'm very suspicious about the condition of the IB network on
my cluster,
I'm trying to use the csum pml feature of OMPI (1.4.3).

  But I have a question: what happens if the Checksum is different on
both ends ?
Is there a warning printed, a flag set by the MPI_(I)recv or equivalent,
and the application aborting ?

  Any help appreciated, Best, G.
