Re: [OMPI users] MPI Spawn functionality and core allocation questions

You may want to look at the —oversubscribe mpirun option. If you want more control, you can consider making a rankfile where you place explicitly processes. Aurélien > Le 29 juin 2016 à 11:50, Jason Maldonis a écrit : > > Hi everyone, > > I am having trouble developing a complicated paral

Re: [OMPI users] Theoretical Differences: Cluster Computing, Distributed Computing, Grid Computing

I have quite different definitions than Jeff. Distributed computing is encompassing all the "parallel computing" models, including clusters, grids, master-slave, shared memory... Everything that basically implies using several collaborating processes to solve a problem (whatever collaborat

Adam. Your MPI program is incorrect. You need to replace the finalize on the process that found the error with MPIAbort On Nov 16, 2017 10:38, "Adam Sylvester" wrote: > I'm using Open MPI 2.1.0 for this but I'm not sure if this is more of an > Open MPI-specific implementation question or what th

Re: [OMPI users] How to enable vprotocol + pessimistic message logging?

Hey Kiril, Indeed, the pessimist message logging does not support threaded accesses. That test is however overly cautious if you are initializing as multiple but then do not perform concurrent accesses. Please verify that he NBP3.3 do MPI_INIT_THREADS(MPI_THREAD_SINGLE), as doing other initial

Re: [OMPI users] Are there any issues (performance or otherwise) building apps with different compiler from the one used to build openmpi?

You can set the environment variable OMPI_CC to change what compiler mpicc uses as the application compiler, irrespective of what compiler Open MPI was built with. That should work for C applications just fine. For Fortran programs the story is more complicated, as the MPI Fortran module woul
