  ## SYNOPSIS

```
#include "pgapack.h"
void  PGASendReceiveIndividual(ctx, send_p, send_pop, dest, send_tag, recv_p, recv_pop, source, recv_tag, comm, status)
PGAContext *ctx
int send_p
int send_pop
int dest
int send_tag
int recv_p
int recv_pop
int source
int recv_tag
MPI_Comm comm
MPI_Status *status
```

## LOCATION

## 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);
```
