Re: [OMPI users] Trouble with MPI-IO

Rob, Thanks for the clarification. I had seen that point about non-decreasing offsets in the standard and it was just beginning to dawn on me that maybe it was my problem. I will rethink my mapping strategy to comply with the restriction. Thanks again. T. Rosmond On Tue, 2011-05-24 at 10:09

Re: [OMPI users] openmpi (1.2.8 or above) and Intel composer XE 2011 (aka 12.0)

OK! I catch the meaning of the "--mca btl_openib_cpc_include rdmacm" parameter. Howerver, as I just said, we are doing, in the meanwhile, several IMB tests on openmpi 1.2.8 and on this (our) version either the RDMA CM support is not implemented or has not been included in the compilation
