Re: [OMPI users] ifort and gfortran module

Why not generate an ifort version with a prefix of _intel And the gfortran version with a prefix of _gcc ? That's what I do and then use mpi-selector to switch between versions as required. Jim -Original Message- From: users-boun...@open-mpi.org [mailto:users-boun...@open-mpi.org] On Be

[OMPI users] ifort and gfortran module

2009-07-17 Thread Martin Siegert
Hi, I am wondering whether it is possible to support both the Intel compiler ifort and gfortran within a single compiled version of openmpi. E.g., 1. compile openmpi ifort as the Fortran compiler and install it in /usr/local/openmpi-1.3.3 2. compile openmpi using gfortran, but do not install it

Okay, just checking the obvious. :-) We regularly run with the exact same configuration here (i.e., slurm + 16cpus/node) without problem on jobs that are both short and long, so it seems doubtful that it would be an OMPI bug. However, it is possible as the difference could be due to configu

I think it unlikely that its a time limit thing. Firstly, slurm is set up with no time limit on jobs, and we get the same behaviour whether or not slurm is in the picture. In addition, we've run several other much larger jobs with a greater number of permutations and they complete fine. This jo

Hi, with a bit of experience I have with the Axis2/C, I think your second model with MPI_Comm_spawn might solve your problem. One of crude restriction with Axis2/C architecture is the run time service loading using static libs. This sometimes prevent many user needed handling where your logic has

I do not know anything about implementing webservices, but you should take a look at MPI-2 dynamic process management. This way, your webservice can MPI_Comm_spawn() a brand-new set of parallel processes doing the heavy work. This way, your webservice will act as a kind of proxy application between

From what I can see, it looks like your job is being terminated - something is killing mpirun. Is it possible that the job runs slowly enough on 14 or less cpus that it simply isn't completing within your specified time limit? The lifeline message simply indicates that a process self-aborte
