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
