>From the look of it, this is not an OMPI problem, but a problem with your paths. You need to make sure that libGLU.so.1 can be found by the system at runtime. This is true for _all_ the systems that are in your machinefile. So make sure that on all systems the path to that library is in the LD_LIB

[OMPI users] OMPI error in MPI_Cart_create (in code that works with MPICH2)

2009-09-01 Thread Greg Fischer
I'm receiving the error posted at the bottom of this message with a code compiled with Intel Fortran/C Version 11.1 against OpenMPI version 1.3.2. The same code works correctly when compiled against MPICH2. (We have re-compiled with OpenMPI to take advantage of newly-installed Infiniband hardware

Hi, I am trying to install openmpi 1.3.3 under OSX 10.6 (Snow Leopard) using the 11.1.058 intel compilers. Configure and build seem to work fine. However trying to run ompi_info after install causes directly a segmentation fault without any additional information being printed. Did anyone h

Marcus, What version of openmpi ships with 10.6. Are you making sure that you are getting the includes and libraries for 1.3.3 and not the native apple version of openmpi. Doug Reeder On Sep 1, 2009, at 4:31 PM, Marcus Herrmann wrote: Hi, I am trying to install openmpi 1.3.3 under OSX 10.

2009-09-01 Thread Marcus Herrmann
just tried the gnu compilers that come with 10.6, and they seem to work (at least ompi_info doesn't crash). So it appears to be an intel compiler issue on 10.6. Just checked out the intel compiler pages, and apparently they don't yet support Snow Leopard. Thanks all for the input. Marcus

[OMPI users] [OT] : Programming on PS3 Cell BE chip ?

Are all the commercial PS3 games developed in "parallel way".(unlike sequential like XBox development) ? Do the developers have *think* in parallel way and use all the MPI_* like commands to communicate with SPEs ?

I am not a game developer, but I don't think any games are actually using MPI in general, let alone to communicate with the SPEs (if that isn't what you were implying, my mistake - I apologize). If you're interested in learning about programming on the Cell BE, take a look at IBM's "Redbook" on
