MPI -如何将avalue发送到数组中的特定位置

#include <stdio.h>
#include <mpi.h>

int main(int argc, char** argv) {
    int rank, size;
    int array[10];

    MPI_Init(&argc, &argv);
    MPI_Comm_rank(MPI_COMM_WORLD, &rank);
    MPI_Comm_size(MPI_COMM_WORLD, &size);

    if (rank == 0) {
        int avalue = 42;
        int destination_rank = 1;
        int destination_index = 5;
        MPI_Send(&avalue, 1, MPI_INT, destination_rank, destination_index, MPI_COMM_WORLD);
    }
    else if (rank == 1) {
        int source_rank = 0;
        int source_index = 5;
        MPI_Recv(&array[source_index], 1, MPI_INT, source_rank, source_index, MPI_COMM_WORLD, MPI_STATUS_IGNORE);
        printf("Received value: %d\n", array[source_index]);
    }

    MPI_Finalize();
    return 0;
}
