[MPICH] SO_REUSEADDR seems not work in programs with MPI

MPI will not do anything to a socket you create on your own.

Subject: [MPICH] SO_REUSEADDR seems not work in programs with MPI


Greetings. In my mpi programs, some socket interface(tcp) is needed. As the
system`s archetecture is designed, I have to close server side first. Then
the error message "Bind: Address Already in Use" is always meet.  I find
that using the function setsockopt() to set SO_REUSEADDR parameter is the
only way to avoid this problem.  But with some experiments I find this way
can't work in MPI programs while work good in socket raw examples.  Is that
because MPI reset the socket option when MPI_Finalize is called?

Any suggestions will be greatly appreciated.
