[mpich-discuss] Runing mpich over InfiniBand Open Fabrics

[Ramiro Alba]

Hi all,

I've compiled mpich-3.1.3 on centos 6.5 with the following options:

         --enable-fortran=yes \
         --with-device=ch3:nemesis:ib \
         --with-pm=hydra:gforker \

and the package 'libibverbs-devel' installed.

When I try to run a test hello program using two IB DDR  nodes, using 
the
command:

mpiexec.hydra -np 16 -bind-to core -launcher rsh -iface ib0 -hosts 
jff201,jff202 mpi_hello

I've got the errors bellow, even running using with root user.

If I compile with:

--with-device=ch3:nemesis

it works with no errors.

I am also using both openmpi and mvapich2 on Infiniband and they work 
fine

Am I doing something wrong when compiling and/or running?
Any sugestion is welcomed?

Thanks in advance
Regards
