Re: [OMPI users] Undefined ompi_mpi_info_null issue

Hi Gilles, Thanks for the reply. I completely forgot that lived in the main library. ldd doesn't show that it read my LD_LIBRARY_PATH (I also push out an LPATH variable just for fun). I force modules to echoed when users initialize them. You can see OpenMPI was visible to H5py. Now I

Re: [OMPI users] Undefined ompi_mpi_info_null issue

Ray, one possibility is one of the loaded library was built with -rpath and this causes the mess an other option is you have to link _error.so with libmpi.so Cheers, Gilles On Friday, June 12, 2015, Ray Sheppard wrote: > Hi Gilles, > Thanks for the reply. I completely

Re: [OMPI users] Looking for LAM-MPI sources to create a mirror

Hi Dave, I use Debian/Ubuntu by default and my first approach (a number of years ago at this stage) was to install from apt. However, if memory serves, I had difficulty getting the packages LAM-MPI to work with the FDS5 software at the time. Obviously, this is specifc to the FDS5 software. My

Re: [OMPI users] Undefined ompi_mpi_info_null issue

Thanks again Gilles, You might be on to something. Dynamic libraries sound like something a Python developer might love (no offense intended to the stereotype). It would also explain why the build went smoothly but the test run crashed. I am going to try putting an RPATH variable in the

[OMPI users] OpenMPI (1.8.3) and environment variable export

Hey there, I know that variable export in general can be done with the -x option of mpirun, but I guess that won't help me. More precisely I have a heterogeneous cluster (number of cores per cpu) and one process for each node. The application I need to launch uses hybrid MPI+OpenMP

Is this a threaded code? If so, you should add —bind-to none to your 1.8 series command line > On Jun 12, 2015, at 7:58 AM, kishor sharma wrote: > > Hi There, > > > > I am facing slowness running numpy code using mpirun with openmpi 1.8.1 > version. > > > > With

Just a follow-up. RPATH was the trouble. All is well now in the land of the climatologists again. Thanks again for the help. Ray On 6/12/2015 8:00 AM, Ray Sheppard wrote: Thanks again Gilles, You might be on to something. Dynamic libraries sound like
