[ofa-general] ibv_ud_pingpong error

[Jeffrey Wong]

Thanks very much.  After setting the limits.conf file for the user with
the memlock setting as unlimited I can now do the ibv_ud_pingpong.  

Thanks again.

Jeff

Hey Jeff,

I think you need to up your locked memory  limits,
We have a faq entry on this here:
http://www.open-mpi.org/faq/?category=openfabrics#ib-locked-pages

Ignore the Open MPI specific parts, the rest I think applies.
