Hello, I am trying to install openmpi-1.6 using the Intel compilers. Looks like everything went fine but there was no mpicc mpif90, mpic++, created during the installation process. I made links to opal-wrapper (and also orterun for mpirun) but then when trying to compile the

Try running: which mpirun ssh cl2n022 which mpirun ssh cl2n010 which mpirun and ldd your_mpi_executable ssh cl2n022 which mpirun ssh cl2n010 which mpirun Compare the results and ensure that you're finding the same mpirun on all nodes, and the same libmpi.so on all nodes. There may well be

You need to pass the following option to configure: --with-devel-headers --enable-binaries I don't know exactly why the default is not to build them anymore, this is a bit confusing. Aurelien Le 1 juin 2012 à 04:16, denis cohen a écrit : > Hello, > > I am trying to install openmpi-1.6

Re: [OMPI users] mpicc, mpif90, ... not created during installation

Jeff, I had the same issue happening to me. It is a pretty new thing, I think it goes back to about a month ago. I thought it was a freak event from stall configure files and didn't reported. Now that others are experiencing it too, there might be something to investigate there. Aurelien

[OMPI users] Intra-node communication

Dear MPI people,    Can someone tell me why MPI_Ssend takes more time when two MPI processes are on same node .. ?? the same two processes on different nodes take much less time for the same message exchange. I am using a supercomputing center and this happens.

This should not happen. Typically, Intra node communication latency are way way cheaper than inter node. Can you please tell us how u ran your application ? Thanks -- Sent from my iPhone On Jun 1, 2012, at 7:34 AM, Mudassar Majeed wrote: > Dear MPI people, >

Re: [OMPI users] Intra-node communication

...and exactly how you measured. You might want to run a well-known benchmark, like NetPIPE or the OSU pt2pt benchmarks. Note that the *first* send between any given peer pair is likely to be slow because OMPI does a lazy connection scheme (i.e., the connection is made behind the scenes).

Dear Jeff, Can you suggest me a quick guide that can help me testing specifically  the across and within node communication. I have some submission today so have no time for googling. If the benchmark tells me the right thing then I will do something accordingly. best

NetPIPE is a 2 process, pt2pt benchmark. Run it with 2 processes both on one node, and then 2 processes with each on different nodes. On Jun 1, 2012, at 12:10 PM, Mudassar Majeed wrote: > Dear Jeff, > Can you suggest me a quick guide that can help me testing > specifically

Hi Edmund The [Torque/PBS] syntax '-l procs=48' is somewhat troublesome, and may not be understood by the scheduler [It doesn't work correctly with Maui, which is what we have here. I read people saying it works with pbs_sched and with Moab, but that's hearsay.] This issue comes back very often

We would rather that OpenMPI use shared-mem (sm) module when running intra-node processes. Doesn't PSM use shared memory to communicate between peers on the same node? Possibly, yes (I'm not sure). Even if it does it appears to consume a 'hardware context' for each peer - this is what
