linux mpirun socket,Problem with MPIRUN run on multi-nodes Under LINUX
Thanks and right now it is OK. However, a new problem occurred again. The details are described as follows:bash-4.1$ lshostfile IMB-EXT IMB-IO IMB-MPI1 IMB-NBC IMB-RMAbash-4.1$ cat hostfileimex-snb2s.
Thanks and right now it is OK. However, a new problem occurred again. The details are described as follows:
bash-4.1$ ls
hostfile IMB-EXT IMB-IO IMB-MPI1 IMB-NBC IMB-RMA
bash-4.1$ cat hostfile
imex-snb2s-rh
imexsvr4-rh
imexsvr3-rh
(*Note: all above 3 computers are 2-socket 16-core SundyBridge DELL computers.)
The following 3 benchmarkings can be successful to run without any errors.
bash-4.1$ mpirun -genv I_MPI_FABRICS shm:tcp -n 32 -f hostfile IMB-MPI1
bash-4.1$ mpirun -genv I_MPI_FABRICS shm:tcp -n 32 -f hostfile IMB-NBC
bash-4.1$ mpirun -genv I_MPI_FABRICS shm:tcp -n 32 -f hostfile IMB-RMA
BUT, the following 2 benchmarking failed to run and errors occurred as follows:
bash-4.1$ mpirun -genv I_MPI_FABRICS shm:tcp -n 32 -f hostfile IMB-IO

Please tell me the reasons why such errors occurred for the benchmarking IMB-IO and IMB-EXT.
Thanks again and I look forward to hearing from you as soon as possible.
