[OMPI users] Cluster : received unexpected process identifier

Hi, I am running a MPI program using cluster and tcp communication. To run I am using: *mpirun --prefix /usr/local/ --mca btl tcp,self --hostfile slaves -np 6 scatter* I am getting following output: Process 0 on host host1 has elements 0 1 2 3 Process 1 on host host1 has elements 4 5 6 7 Proc

Re: [OMPI users] [EXTERNAL] Using One-sided communication with lock/unlock

Thank you for the hint. I thought that "the same process" refers to the locked window, not to the calling process. Maybe I can work around this restriction with a dummy window for synchronization ... Thanks again, Sebastian > On 4/3/12 12:01 PM, "Sebastian Rettenberger" wrote: > >I posted th

Hello, I posted the bug report a week ago, but unfortunately I didn't get any response: https://svn.open-mpi.org/trac/ompi/ticket/3067 The example (see bug report) is very simple, however it still fails. Other MPI versions work fine (e.g. Intel MPI). This is a real show stopper for me. Any hel

[OMPI users] Problem in using Linpack with open MPI when specifying the host file

Hi, I tried to benchmark a condor HPC cluster I installed open MPI on all the nodes (3 nodes) when I run mpi program and specifying the host file it works on all the nodes but when I tried to run the Linpack it does not work as expected (it takes most of the processor power but the memory stil

Re: [OMPI users] sge tight intregration leads to bad allocation

Hi Ralph,   Thanks for your feedback. No, this is the other way around, the “reserved” slots on all nodes are ok but the “used” slots are different.   Basically, I’m using SGE to schedule and book resources for a distributed job. When the job is finally launched, it uses a different allocation

Re: [OMPI users] sge tight intregration leads to bad allocation

Hi Tom, I'm using orterun to launch the computation. Basically, I use the qsub from Sge to submit a run to our cluster. The booked resources will be read and used by orterun whe the job will be launched ( using tight-integration). I might be wrong, but this would mean that the issue ob

Re: [OMPI users] sge tight intregration leads to bad allocation

I'm afraid there isn't enough info here to help. Are you saying you only allocated one slot/node, so the two slots on charlie is in error? Sent from my iPad On Apr 3, 2012, at 6:23 AM, "Eloi Gaudry" wrote: > Hi, > > I’ve observed a strange behavior during rank allocation on a distributed run

Re: [OMPI users] sge tight intregration leads to bad allocation

How are you launching the application? I had an app that did an Spawn_multiple with tight SGE integration, and there was a difference in behavior depending on whether or not an app was launched via mpiexec. I¹m not sure whether it¹s the same issue as you¹re seeing, but Reuti describes the problem

[OMPI users] sge tight intregration leads to bad allocation

Hi, I've observed a strange behavior during rank allocation on a distributed run schedule and submitted using Sge (Son of Grid Egine 8.0.0d) and OpenMPI-1.4.4. Briefly, there is a one-slot difference between allocated rank/slot for Sge and OpenMPI. The issue here is that one node becomes over
