[OMPI users] mpicc Segmentation Fault with Intel Compiler

Hi, I've the same problem described by some other users, that I can't compile anything if I'm using the open-mpi compiled with the Intel- Compiler. > ompi_info --all Segmentation fault OpenSUSE 10.3 Kernel: 2.6.22.9-0.4-default Intel P4 Configure-Flags: CC=icc, CXX=icpc, F77=ifort, F90=ifort

[OMPI users] Re: [OMPI users] MPI_Probe succeeds, but subsequent MPI_Recv gets stuck

Just a thought, Behaviour can be unpredictable if you use MPI_Bsend or MPI_Ibsend ... on your sender side cause nothing is checked regard to allocated buffer. MPI_Send or MPI_Isend shall be used instead. Regards Herve ALICE C'EST ENCORE MIEUX AVEC CANAL+ LE BOUQUET

[OMPI users] OpenMPI - can you switch off threads?

I'm trying to build a udapl OpenMPI from last Friday's SVN and using Qlogic/QuickSilver/SilverStorm 4.1.0.0.1 software. I can get it made and it works in machine. With IB between 2 machines is fails near termination of a job. Qlogic says they don't have a threaded udapl (libpthread is in the trace

Re: [OMPI users] OpenMPI - can you switch off threads?

All thread support is disabled by default in Open MPI; the uDAPL BTL is neither thread safe nor makes use of a threaded uDAPL implementation. For completeness, the thread support is controlled by the --enable-mpi-threads and --enable-progress-threads options to the configure script. The refer

[OMPI users] Job does not quit even when the simulation dies

Hi, Just realize I have a job run for a long time, while some of the nodes already die. Is there any way to ask other nodes to quit ? [kyla-0-1.local:09741] mca_btl_tcp_frag_send: writev failed with errno=104 [kyla-0-1.local:09742] mca_btl_tcp_frag_send: writev failed with errno=104 T

Unfortunately, not yet. I believe that this kind of functionality is slated for the v1.3 series -- is that right Ralph/Voltaire? On Nov 5, 2007, at 11:22 AM, Karsten Bolding wrote: Hello I'm using a machinefile like: n03 n04 n03 n03 n03 n02 n01 .. .. .. the order of the entries is determi

Re: [OMPI users] Slightly OT: mpi job terminates

You might want to run your app through a memory-checking debugger to see if anything obvious shows up. Also, check to see if your corelimit size is greater than zero (i.e., make it "unlimited"). Then run again and see if you can get corefiles to see if your app is silently dumping core, an
