EXAMPLE

Example:
A dedicated process is being used to perform an optimization algorithm
on the strings.  Send a new string, s, to the process, while receiving an
optimized string, r, from it.

PGAContext *ctx;
MPI_Comm    comm;
MPI_Status  status;
int  s, r;
:
PGASendReceiveIndividual(ctx, s, PGA_NEWPOP, 1, PGA_SR_STRINGTOMODIFY,
r, PGA_NEWPOP, 1, PGA_SR_MODIFIEDSTRING,
comm, &status);
