[OMPI users] MPI_THREAD_MULTIPLE causes deadlock in simple MPI_Barrier case (ompi 1.6.5 and 1.7.3)

Hi, I've compiled ompi1.6.5 with multi-thread support (using Intel compilers 12.0.4.191, but I get the same result with gcc) : ./configure --with-tm/opt/torque --with-openib --enable-mpi-thread-multiple CC=icc CXX=icpc F77=ifort FC=ifort And i've built a simple sample code that only does the Init

Re: [OMPI users] openmpi+torque: How run job in a subset of the allocation?

Hi, Here is what I do to execute 20 mpirun calls using LSF and one job but it is similar for your case I assume. I use $LSB_HOSTS to extract the hosts from the job. I know how many cores I want per job so I create machine files. For our application, each execution has its own nodes but the l
