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);
