[O-MPI users] how do you select which network/trasport to use at run-time?

2005-08-23 Thread Peter Kjellström
Hello, First I'd like to say that I'm really happy and excited that public access to svn is now open :-) Here is what went fine: check-out, autogen, configure, make, ompi_info and simple mpi app (both build and run!!!) Now I'd like to control over which channels/transports/networks the data f

Hi Peter, I'm a little surprised that tcp was used -- OMPI should "prefer" the low latency interconnects (such as mvapi) to tcp and automatically use them. This is a small issue and should be fixed in the next day or two. In the meantime to run using mvapi only use: mpirun -np 2 -mca

[O-MPI users] MIPS64 question

2005-08-23 Thread Jonathan Day
Hi, I notice that MIPS is not listed amongst the "known" architectures in the README, and on trying to compile OpenMPI on a Linux/MIPS64 platform it blew up in the configuration code. Having said that, there does seem to be MIPS stuff in those directories listing assembly code, but I do NOT know
