Sorry for this. This was an try and ERROR ERROR Problem. It was a mismatch of OFED versions and kernel updates.
Now I installed a fresh centOS 6.4 (with default kernel NO KENELUPDATE). Then installed the official MELLANOX OFED Driver and compiled openMPI (without options). And now it works fine. Before it was a mismatch of first installing centOS 6.3, then updating to 6.4 and maybe some files of the old OFED drivers survived.
