Hi,

I tried to execute by MPI program using LAM and with GM driver.
My programming can finish without error on np equal to 1, 2, 4. However,
as i running the program with np equals greater than 8. The program hanged
in some where in MPI_Comm_dup for all ranks. The same program can be
executed using others rpi drivers, like tcp, usysv and so on. Any idea on
what is happening ?

Best Regards,
Wing-Seung Yuen
