Now we are facing that "mpirun -np 2 -ppn 1 ./mpi-program.out" does not work. It always run all processes on same node. LSF support said it is not related LSF. What does it caused by ? And how do we investigate this issue ? Translate0...
MPI_Comm_spawn on ofi/mlx does not work on non-IA platform. As a workaround ofi/verbs provider on small scale may be used. On hybrid processors with efficient E-cores and performance P-cores, such as 12th and 13th Gen Intel® Core™ processors, Intel MPI Library might pin processes ...
NOTE: OpenMPI has a limitation that does not support calls to MPI_Comm_spawn() from within a Slurm allocation. If you need to use the MPI_Comm_spawn() function you will need to use another MPI implementation combined with PMI-2 since PMIx doesn't support it either. NOTE: Some kernels...
(http://arxiv.org/abs/1602.03638), with thousands of processors on a Blue Gene supercomputer. Using pyfftw to do the serial FFT and then mpi4py to do the required MPI communications does not really require much work and if you are already working in Python, there's really no good ...

However, I do not understand why this command does not work when an Infiniband card is installed: mpirun -np 2 hello_c on Apr 5, 2019 vaderis used for intra node communications but only whenpml/ob1is used.pml/cmhas a higher priority and is selected because of libfabric. It seems libf...
