Calling Sequence
res = MPI_Send(value,node)
Arguments
- value
The value to be sent to the specified node.
- node
The node to send the data
- res
The result of the operation (true if success, false if failed)
Description
Send a variable to a specified node. The value should be retrieved by the node with the function MPI_Recv.
Examples
MPI_Init(); rnk = MPI_Comm_rank(); sizeNodes = MPI_Comm_size(); SLV = rnk; // handy shortcuts, master is rank 0 Master = ~ SLV; // slaves are all other tag=0; if Master // The master node for slaveId = 1:sizeNodes-1 // Send data to the slaves value = rand(100,100) + rand(100,100) * %i; MPI_Send(value, slaveId); end for slaveId = 1:sizeNodes-1 valueBack=MPI_Recv(slaveId, tag); // Check that the slaves gaves us what we expected assert_checkequal(valueBack,value + 1); end else // The slaves rankSource=0; // Receive the information from the master value=MPI_Recv(rankSource); // Increment all the values by one value=value+1; // Send back to the master MPI_Send(value,0); end MPI_Finalize();
