You are creating an application that uses Microsoft Message Passing Interface (MPI). The library has the following communication primitives:
Blocking communication primitives like send and receive operations Non-blocking communication primitives like n_send and n_receive operations You write the following code segment for the processes named P0 and P1 in the application.
(Line numbers are included for reference only.)

01 P0:
02 for (i = 0; i < 1000; i++) {
03 produce_data(&data[i]);
04 send(&data[i], 1, P1);
05 }
06
07 P1:
08 for (i = 0; i < 1000; i++) {
09 receive(&a, 1, P0);
10 process_data(&a);
11 }

Users report that the application processes data slowly. You need to ensure that the application processes data quickly.
What should you do?

A.
Split the P0 process into 1,000 separate processes.

B.
Split the P1 process into 1,000 separate processes.

C.
Replace the send operation with the n_send operation in the P0 process.

D.
Replace the receive operation with the n_receive operation in the P1 process.
