Re: [OMPI users] Can't start more than one process in a node as normal user

Hi Ralph and Brian, Thanks for the advice, I have checked the permission to /tmp drwxrwxrwt 19 root root 4096 Jan 18 11:38 tmp which I think there shouldn't be any problem to create files there, so option (a) still not work for me. I tried option (b) which set --tmpdir on command line and

You are absolutely correct. Today is just the day for Fortran issues. :-) I've filed bug #782 (https://svn.open-mpi.org/trac/ompi/ticket/782) about this and get it fixed up for v1.2. Thanks for reporting! On Jan 17, 2007, at 2:04 PM, Tim Campbell wrote: The interface definition for MP

[OMPI users] mpi_initialized interface

The interface definition for MPI_Initialized in ompi/mpi/f90/scripts/mpi-f90-interfaces.h.sh is incorrect. The script is generating the interface as subroutine MPI_Initialized(flag, ierr) integer, intent(out) :: flag integer, intent(out) :: ierr end

Re: [OMPI users] Can't start more than one process in a node as normal user

errno 13 on Linux is EACCESS. According to the man page, ftruncate() only retrns errno 13 if the file is owned by another user. I can't see exactly how this could occur, but you might want to look at /tmp/ and make sure everything in openmpi-sessions-eddie* is owned by user eddie. Bri

Re: [OMPI users] openmpi on altix

I would guess that for Open MPI v1.1, we will use more vmem than MPT. Our strategy early on was get a huge buffer and never run out of resources. Obviously, that's not a good long term plan ;). We've scaled this down considerably in v1.2 (now in beta), where we by default use about 16MB/

Hi Eddie Open MPI needs to create a temporary file system ­ what we call our ³session directory² - where it stores things like the shared memory file. From this output, it appears that your /tmp directory is ³locked² to root access only. You have three options for resolving this problem: (a) you

so this isn't really an OpenMPI questions (I don't think), but you guys will have hit the problem if anyone has... basically I'm seeing wildly different bandwidths over InfiniBand 4x DDR when I use different kernels. I'm testing with netpipe-3.6.2's NPmpi, but a home-grown pingpong sees the same

Dear all, I have recently installed OpenMPI 1.1.2 on a OpenSSI cluster running Fedora core 3. I tested a simple hello world mpi program (attached) and it runs ok as root. However, if I run the same program under normal user, it gives the following error: [eddie@oceanus:~/home2/mpi_tut]$ mpirun -

I found that MPT uses a *lot* of vmem for buffering/mem mapping. We schedule based on requested vmem, so this can be a problem. Do you know how vmem usage for buffering compares with OpenMPI? Cheers, Aaron -Original Message- From: users-boun...@open-mpi.org [mailto:users-boun...@open-mpi.
