Hi Ramiro, Our folks that contributed that netmod are looking into this issue. In the meantime, I'd suggest trying the MXM netmod. MXM is a netmod for IB networks using the MXM API instead of Verbs to interact with the HCA. Best, Antonio On 01/15/2015 05:52 AM, Ramiro Alba wrote:

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
