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

[Matthew Koop]

Ben,

Sorry to hear about this issue. Can you give me some more details on your
installation -- what distro are you using and is OFED being used?  Also,
what version of MVAPICH are you using?

Additionally, what is the output of 'ulimit -l' on your system (or
equivalent shell command). You may want to check all nodes. Memory
registration generally does not fail unless the amount of lockable memory
is too low.
