Hi all,

I m facing problem while running Openfoam1.5  the executable is sonicTurbFoam with the help of openmpi it hang after some time, every time it hang at different place. The Mpi command is

 mpirun --mca btl_openib_if_include ib0 -mca btl_tcp_if_exclude lo,eth0,eth1 --mca btl_openib_ib_timeout 40 -n $NO_OF_PROCESS -machinefile $MYHOSTS $1 -parallel

We are using 64 processor on 8 nodes.

I m submitting it with the help of lsf scheduler and internally it usage SLURM as a resource manager.

Error :
[n112][0,1,41][btl_tcp_frag.c:202:mca_btl_tcp_frag_recv] mca_btl_tcp_frag_recv: readv failed with errno=110
