2016-05-20 Thread Siegmar Gross
Hi, I tried MPI.ERRORS_RETURN in a small Java program with Open MPI 1.10.2 and master. I get the expected behaviour, if I use a wrong value for the root process in "bcast". Unfortunately I get an MPI or Java error message if I try to broadcast more data than available. Is this intended or is it

[OMPI users] [slightly off topic] hardware solutions with monetary cost in mind

Hello, Say I don't have access to a actual cluster, yet I'm considering cloud compute solutions for my MPI program ultimately, but such a cost may be highly prohibitive at the moment. In terms of middle ground, if I am interesting in compute only, no storage, what are possible hardware solutions

If you look around on Ebay, you can find old 16-core Opteron servers for a few hundred dollars. It's not screaming performance, but 16 cores is enough to get you started on scaling and parallelism in MPI. It's a cheap cluster in a box. Damien On 5/20/2016 12:40 PM, MM wrote: Hello, Say I
