Hi list, It appears there is a problem with the OpenMPI I/O library on CentOS 6.2 & 6.3 (package openmpi-1.5.4-1.el6.x86_64). When I compile the attached program it ends up in the error path since MPI_File_open returns 16. The corresponding (unhelpful) message is: MPI_ERR_OTHER: known error not in list I couldn't find any pointers on the net and the same program works with OpenMPI

Dear ext3-users, I write scientific number-crunching codes which deal with large input and output files (Gb, tens of Gb, as much as hundreds of Gygabytes on occasions). Now there are these multi-core setups like Intel Core 2 Duo becoming available at a low cost. Disk I/O is one of the biggest bottlenecks. I would very much like to put to use the multiple processors to read or write in parallel
