Dear OMPI users and builders: I recently installed the latest version of Open MPI (1.2.6) on my Mac Pro, which has 2 dual-core Intel cpu's. On the plus side, I can successfully compile and run MPI codes written both in fortran77 and in c on all 4 cores with the corresponding wrappers that the

[OMPI users] Allocating some amount of memory for a process

2008-04-17 Thread Cally K
Hi everyone Hi, am a beginner in openmpi, does openmpi provide a function for allocating memory to a process. For example, I have a rendering process from paraview named pvserver and I would like to allocate a certain amount of memory for that process across a few nodes specified in the hostfile..

OpenMPI does not do this. MPI codes are regular C and Fortran programs, so if they ALLOCATE or malloc() memory, and linux/mac can give it it will. I think what you need is a batch system (Torque Plug goes here). We use a batch system that will then place processes on nodes based on memo

Hi Graham, Have you tried running without the btl_tcp_if_include line in the .conf file? Open MPI is usually smart enough to auto detect and choose the correct interfaces. Hope this helps, Tim Graham Jenkins wrote: We're moving from using a single (eth0) interface on our execute nodes to u

Can you double check that you are using the wrapper compilers from the Open MPI installation that you think you're using? Tiger doesn't ship with Open MPI, so you shouldn't have problems conflicting with a system-installed OMPI, but could you possibly have another OMPI install hanging aroun

Hi. Anyone had performed Gromacs(v3.x - v3.3.3) with FFTW(v3.1) debugging using OpenMPI(v-1.2.5 or v-1.2.6). I had properly configured OpenMPI with debug option and also configured Gromacs alongwith FFTW succesfully. I can perform p2bdbx_mpi, editconf_mpi, genbox_mpi, grompp_mpi compilation and fi
