[OMPI users] Multi-threading with OpenMPI ?

Greetings all, Please refer to image at: http://i27.tinypic.com/mtqurp.jpg Here the process illustrated in the image: 1) C++ Webservice loads the "libParallel.so" when it starts up. (dlopen) 2) When a new request comes from a client,*new thread* is created, SOAP data is bound to C++ objects

[OMPI users] Timers

Hi all, I want to get the elapsed time from start to end of my parallel program (OPENMPI based). It should give same time for the same problem always; irrespective of whether the nodes are running some or programs or they are running only that program. How to do this? Regards.

Hi, how exactly do you run this to get this error? I tried and it worked for me. burl-ct-x2200-16 50 =>mpirun -mca btl_openib_warn_default_gid_prefix 0 -mca btl self,sm,openib -np 2 -host burl-ct-x2200-16,burl-ct-x2200-17 -mca btl_openib_ib_timeout 16 a.out I am 0 at 1252670691 I am 1 at

Re: [OMPI users] Bad MPI_Bcast behaviour when running over openib

Cisco is no longer an IB vendor, but I seem to recall that these kinds of errors typically indicated a fabric problem. Have you run layer 0 and 1 diagnostics to ensure that the fabric is clean? On Sep 11, 2009, at 8:09 AM, Rolf Vandevaart wrote: Hi, how exactly do you run this to get

[OMPI users] OpenMPI on OS X - file is not of required architecture

Andreas, Have you checked that ifort is creating 64 bit objects. If I remember correctly with 10.1 the default was to create 32 bit objects. Doug Reeder On Sep 11, 2009, at 3:25 PM, Andreas Haselbacher wrote: On Fri, Sep 11, 2009 at 5:10 PM, Jeff Squyres wrote: On
