[問題] mpi c改成分散式運算架構
我要做多台雲端一起合作執行code，好像俗稱跨節點加分散式運算
以下是我原code
#include <stdio.h>
#include <time.h>
main(){
int max = 10000;
int i;
time_t now;
time(&now);
for(i = 1; i <= max;i++){
printf("%d\n",i);
}
time_t now2;
time(&now2);
printf("It's %s\n", ctime(&now));
printf("It's %s", ctime(&now2));
}
後來我加了mpi
#include <stdio.h>
#include <mpi.h>
#include <time.h>
int main (argc, argv)
int argc;
char *argv[];
{
int rank, size;
MPI_Init (&argc, &argv); /* starts MPI */
MPI_Comm_rank (MPI_COMM_WORLD, &rank); /* get current process id */
MPI_Comm_size (MPI_COMM_WORLD, &size); /* get number of processes */
int max = 10000
int i;
time_t now;
time(&now);
for(i = 0; i <= max;i++){
printf("%d\n",i);
}
time_t now2;
time(&now2);
printf("It's %s\n", ctime(&now));
printf("It's %s", ctime(&now2));
printf( "Hello world from process %d of %d\n", rank, size );
MPI_Finalize();
return 0;
}
可是運算後好像不大對，變成每個節點都各算一遍，
而非我所要的各節點一起分工
請問有大大寫過mpi的嗎?
