[mvapich-discuss] Abort: unable to register vbuf DMA buffer at line 211 in file vbuf.c

[Ben Held]

We have recently built our MPI application using MVAPICH1 under LINUX and
are seeing certain runs fail (success or failure seems to be a function of
the # of processes - 8 will work, 16 will fail, 32 will work, etc).  This
code has been thoroughly testing using the standard MPICH (Ethernet based)
and LAM and everything is fine.

 

Does this error:

 

Abort: unable to register vbuf DMA buffer at line 211 in file vbuf.c

 

Mean anything?  This is a new cluster (8 node, 8 cores per node) has been
tested under using stress tests provided by the cluster manufacturer
(Microway).  This is out of my area of expertise and this is the first IB
based system I have worked on.

 

Any thoughts?
