Re: [OMPI users] Open-MPI 1.2 and GM

Justin, There is no GM MTL. Therefore, the first mpirun allow the use of every available BTL, while the second one don't allow intra-node communications or self. The correct mpirun command line should be: mpirun -np 4 --mca btl gm,self ... george. On Mar 27, 2007, at 12:18 PM, Justin

Re: [OMPI users] Issues with Get/Put and IRecv

Well, mpich2 and mvapich2 are working smoothly for my app. mpich2 under gige is also giving ~2X the performance of openmpi during the working cases for openmpi. After the paper deadline, I'll attempt to package up a simple test case and send it to the list. Thanks! -Mike Mike Houston

[OMPI users] Open-MPI 1.2 and GM

Having a user who requires some of the features of gfortran in 4.1.2, I recently began building a new image. The issue is that "-mca btl gm" fails while "-mca mtl gm" works. I have not yet done any benchmarking, as I was wondering if the move to mtl is part of the upgrade. Below are the

Re: [OMPI users] MPI processes swapping out

I tried the trunk version with "--mca btl tcp,self". Essentially system time changes to idle time, since empty polling is being replaced by blocking (right?). Page faults go to 0 though. It is interesting since you can see what is going on now, with distinct phases of user time and idle time

Re: [OMPI users] very long linking time with mixed-language libraries

I notice that you are using the "medium" sized F90 bindings. Do these FAQ entries help? http://www.open-mpi.org/faq/?category=mpi-apps#f90-mpi-slow-compiles http://www.open-mpi.org/faq/?category=building#f90-bindings-slow-compile On Mar 27, 2007, at 2:21 AM, de Almeida, Valmor F. wrote:

[OMPI users] very long linking time with mixed-language libraries

Hello, I am using mpic++ to create a program that combines c++ and f90 libraries. The libraries are created with mpic++ and mpif90. OpenMPI-1.2 was built using gcc-4.1.1. (below follows the output of ompi_info. The final linking stage takes quite a long time compared to the creation of the
