[OMPI users] unable to open osc pt2pt

Hello, I am getting these messages (below) when running mpi4py python codes. Always one message per mpi process. The codes seem to run correctly. Any ideas why this is happening and how to avoid it? Thanks, -- Valmor de Almeida >mpirun -np 2 python helloworld.py [xeon0:05998] mca: base:

Re: [OMPI users] Configure fails with icc 10.1.008

Eric, I see you are using a gentoo distro like me. My version uses the vanilla kernel 2.6.22.9 and gcc-4.1.2. I have the following intel compiler versions installed: 10.0.026 10.1.008 10.1.011 9.1.052 None of them are able to build a functional version of openmpi-1.2.4. I've been posting

uild on that platform (including Open MPI). The install script of the 10.1.008 suite lists the supported platform. That includes kernel 2.6 and glibc 2.6. I guess there are some loose ends. -- Valmor > > > > On Dec 5, 2007, at 9:59 AM, de Almeida, Valmor F. wrote: > > &g

[OMPI users] suggested intel compiler version for openmpi-1.2.4

Hello, What is the suggested intel compiler version to compile openmpi-1.2.4? I tried versions 10.1.008 and 9.1.052 and no luck in getting a working library. In both cases I get: ->mpic++ --showme Segmentation fault ->ompi_info Segmentation fault Thanks for your help. -- Valmor de Almeida

Hello, After compiling ompi-1.2.4 with the intel compiler suite 10.1.008, I get ->mpicxx --showme Segmentation fault ->ompi_info Segmentation fault The 10.1.008 is the only one I know that officially supports the linux kernel 2.6 and glibc-2.6 that I have on my system. config.log file

Hello, I am getting the warnings after an upgrade to mx-1.2.4 and openmpi-1.2.4. Either using the env variable setting MX_RCACHE=2, or linking the application with -lmyriexpress removes the warnings. Is either one of them the preferred way of doing it? Thanks, -- Valmor > -Original

[OMPI users] mpi python recommendation

Hello list, I would appreciate recommendations on what to use for developing mpi python codes. I've seen several packages on public domain: mympi, pypar, mpi python, mpi4py and it would be helpful to start in the right direction. Thanks, -- Valmor de Almeida ORNL PS. I apologize if this

[OMPI users] experiences with gfortran and ompi

Hello, I would be interested in hearing folk's experiences with gfortran and ompi-1.2. Is gfortran good enough for prime time? I have built ompi-1.2 with gfortran-4.1.1 but no luck in testing it because my application of interest (legacy fortran code) will not compile with gfortran. In

Hello, I am getting this error any time the number of processes requested per machine is greater than the number of cpus. I suspect it is something on the configuration of mx / ompi that I am missing since another machine I have without mx installed runs ompi correctly with oversubscription.
