It would be very strange for nanosleep to cause a problem for Open MPI -- it shouldn't interfere with any of Open MPI's mechanisms. Double check that your my_barrier() function is actually working properly -- removing the nanosleep() shouldn't affect the correctness of your barrier. If you'v

I am having trouble with trace-enabled comilation of CG.W.8 benchmark included in NAS Parallel Benchmark. As the makefile is dependent to other files in the common directory, so obviously independent compiling of the cg.f wouldn't work: mpif77 -o cg_log cg.f -llmpe -lmpe This is the makefile given

To compile fortran application with MPE, you need Fortran to C wrapper library, e.g. libmpe_f2cmpi.a or the one that comes with OpenMPI. Your link command should contain at least the following mpif77 -o cg_log cg.f -lmpe_f2cmpi -llmpe -lmpe. To simplify the process, the recommended way to enabl

2010-01-12 Thread Ralph Castain
Without progress threads, you can only recv messages when you call a function in the OMPI library - e.g., when you send something. In addition, you only recv -one- message for each time you call into the library. With progress threads, you recv messages when they arrive, even if you aren't in t

[OMPI users] Problems Using PVFS2 with OpenMPI

I am unable to use PVFS2 with OpenMPI in a simple test program. My configuration is given below. I'm running on RHEL5 with GigE (probably not important). OpenMPI 1.4 (had same issue with 1.3.3) is configured with ./configure --prefix=/work/rd/evan/archives/openmpi/openmpi/1.4/enable_pvfs \ --enab
