MPI problem with shm fabric

Hi,

I get the error shown below when trying to run the "hello world" test programwith Intel MPI 4.0.1. It does not occur when running on the same node, only across nodes. If I set I_MPI_FABRICS=tcp, it works fine, but if I set I_MPI_FABRICS=shm:tcp, it also fails. Any ideas?

Fatal error in MPI_Init: Other MPI error, error stack:

MPIR_Init_thread(527).................: Initialization failed

MPID_Init(171)........................: channel initialization failed

MPIDI_CH3_Init(70)....................:

MPIU_SHMW_Seg_open(942)...............:

MPIU_SHMW_Seg_create_attach_templ(826): unable to allocate shared memory - OpenFileMapping The system cannot find the file specified.

job aborted:

Hi rs8421,

It seems to me that you are using Windows operating system, aren't you? What version?
We've never seen such error before. Probably that happens because of incorret synchronization, but we cannot tell you what's wrong with your system.

Regards!
Dmitry
