Re: [OMPI users] IMB-MPI broadcast test stalls for large core counts: debug ideas?

Std TCP/IP stack it hung with an unknown but large(ish) quantity of data.  when I ran just one Bcast it was fine but Bcasts in lots in separate MPI_WORLD's hung.   - All the details are in some recent posts. I could not figure it out and moved back to my PVM solution. --- On Wed, 25/8/10,

Ummmthe configure log terminates normally, indicating it configured fine. The make log ends, but with no error shown - everything was building just fine. Did you maybe stop it before it was complete? Run out of disk quota? Or...? On Aug 24, 2010, at 1:06 PM, Michael E. Thomadakis wrote: >

Hello OpenMPI developers, I am searching for a way to discover _all_ configure options of an OpenMPI installation. Background: in a existing installation, the ompi_info program helps to find out a lot of informations about the installation. So, "ompi_info -c" shows *some* configuration
