Hi everyone,
I have installed openmpi-1.2.3. My system has two ethernet ports. Thus, I am
trying to make use of both ports to speed up the communication process by using
openmp to split into two threads. However, this implementation always cause
error. Then I realized that I need to build openmpi using --enable-mpi-threads
and use MPI_Init_thread to initialize. But, the initialization always return
MPI_THREAD_SINGLE no matter what value I set. Using ompi_info|grep Thread, it
shows that thread support has already been activated. Thus, I seek your help to
teach me what other configurations I need to set in order to use multi-threads
and what are the parameters to include in mpirun in order to use the two
ethernet ports.
Thank you very much.
Regards,
Tee
