[OMPI users] Related to project ideas in OpenMPI

I am final year grad student looking for my final year project in OpenMPI.We are group of 4 students. I wanted to know about the "Process Migration" process of MPI processes in OpenMPI. Can anyone suggest me any ideas for project related to process migration in OenMPI or other topics in Systems.

Be aware that process migration is a pretty complex issue. Josh is probably the best one to answer your question directly, but he's out today. On Aug 24, 2011, at 5:45 AM, srinivas kundaram wrote: > I am final year grad student looking for my final year project in OpenMPI.We > are group of 4

Re: [OMPI users] Documentation of MPI Implementation

Thanks Jeff, I know it depends and I want to know exactly what is the dependency and general complexity analysis. Is it really no documentation at all ? For example you said "to be replaced soon", then what is the algorithms that will be used to replace ? Is there any publication available ? In

[OMPI users] Compiling both 32-bit and 64-bit?

Hi, Quick question: is there an easy switch to compile and install both 32-bit and 64-bit OpenMPI libraries into a single tree? E.g. 64-bit in /prefix/lib64 and 32-bit in /prefix/lib. Thanks, - D.

Re: [OMPI users] Compiling both 32-bit and 64-bit?

Thanks, Brian, I'm trying to follow the guide for 1.5.4, not yet clear what's wrong: [marcusmae@zacate build32]$ ../configure --prefix=/opt/openmpi_kgen-1.5.4 --includedir=/opt/openmpi_kgen-1.5.4/include/32 --libdir=/opt/openmpi_kgen-1.5.4/lib32 --build=x86_64-unknown-linux

Re: [OMPI users] Compiling both 32-bit and 64-bit?

Can you try to build without specifying the --build, --host, and --target options and just specifying the various FLAGS options as either -m32 or -m64 as appropriate? If that doesn't clean things up, can you include all the information requested here: http://www.open-mpi.org/community/help/
