Function PGASendReceiveIndividual

Function Documentation

void PGASendReceiveIndividual(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)

Send an individual to a process, while receiving a different individual from a different process.

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
  );

Parameters:

  • ctx – context variable

  • send_p – index of string to send

  • send_pop – symbolic constant of population to send from

  • dest – destination process

  • send_tag – tag to send with

  • recv_p – index of string to receive

  • recv_pop – symbolic constant of population to receive from

  • source – process to receive from

  • recv_tag – tag to receive with

  • comm – an MPI communicator

  • status – pointer to the MPI status structure

Returns:

status and string recv_p in population recv_pop are modified by side-effect
