I use 2 processor for parallel in shared memory.
When I run in one processor (no parallel) the time of
calculation is 5157 seconds.
when run in 2 processor,(one master, one slave) the
time is 5324 seconds.
So, the time communications is 167 seconds. As I know
there is nearly no communication in shared memory. So
what is the reason that contribute the time (167
seconds.) Thanks.
p/s.I just use mpi_send and mpi_recv.
