[mvapich-discuss] mvapich libraries error

[Ursula Winkler]

Dear Mailinglist-members,

I installed mvapich-1.8 (compiled with Intel Compiler) on a CentOS 6.1 
Cluster.  The infiniband software is MLNX_OFED_LINUX-1.5.3-3.0.0.
On the master-node everything is ok, but on the clusternodes I get the 
following error executing "osu_bw" (osu benchmark):

[root at f02 osu_benchmarks]# mpiexec -bootstrap rsh -n 2 ./osu_bw
mlx4: There is a mismatch between the kernel and the userspace 
libraries: Kernel does not support XRC. Exiting.
mlx4: There is a mismatch between the kernel and the userspace 
libraries: Kernel does not support XRC. Exiting.
CMA: unable to open RDMA device
CMA: unable to open RDMA device

Nevertheless the output of the benchmark is ok, but when testing another 
testprogramm (cpi.x) then mpiexec just is hanging
(without giving any output).

I don't understand the error because on the master-node the same 
MLNX_OFED is installed and there are no
problems. Any ideas?

Thanks,
Ursula
