Re: [CentOS] OpenMPI I/O not working

Hello again,

I dug a bit deeper and found that the default IO component (romio) is not built due to an autoconf issue I don't understand. It looks like some macros in ompi/mca/io/romio/romio/configure are not expanded/substituted.

Cheers, Cihan

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 1.4.5 on a debian system.

Any help would be greatly appreciated.

Cheers, Cihan
