Hello, I use openmpi. I have installed it in the directory : /usr/lib64/openmpi/1.2.5-gcc/
If I execute a test with openMPI (for exemple helloworld!!!) I have the next problem: /*[nmoulin@clusterdell ~/mpi-test]$ mpirun -np 4 mpi-test libibverbs: Fatal: couldn't read uverbs ABI version. -------------------------------------------------------------------------- [0,1,1]: OpenIB on host node01 was unable to find any HCAs. Another transport will be used instead, although this may result in lower performance. -------------------------------------------------------------------------- -------------------------------------------------------------------------- [0,1,1]: uDAPL on host node01 was unable to find any NICs. Another transport will be used instead, although this may result in lower performance. -------------------------------------------------------------------------- libibverbs: Fatal: couldn't read uverbs ABI version. -------------------------------------------------------------------------- [0,1,2]: OpenIB on host node02 was unable to find any HCAs.

Now, if I execute the same job with the mca parameters all is OK.....hum I think. /*[nmoulin@clusterdell ~/mpi-test]$ mpirun -mca btl tcp,self -np 4 mpi-test Hello world! from processor 0 out of 4 Hello world! from processor 1 out of 4 Hello world! from processor 3 out of 4 Hello world! from processor 2 out of 4 [nmoulin@clusterdell ~/mpi-test]$*/ I've try to get the mca parameters in the file /usr/lib64/openmpi/1.2.5-gcc/etc/openmpi-mca-params.conf but it seems not to take into account.... Can you help me do that? Kind regards,
