我试图编译一个非常简单的 MPI hello_world:
#include <stdio.h>
#include <mpi.h>
int main(int argc, char *argv[]) {
int numprocs, rank, namelen;
char processor_name[MPI_MAX_PROCESSOR_NAME];
MPI_Init(&argc, &argv);
MPI_Comm_size(MPI_COMM_WORLD, &numprocs);
MPI_Comm_rank(MPI_COMM_WORLD, &rank);
MPI_Get_processor_name(processor_name, &namelen);
printf("Process %d on %s out of %d\n", rank, processor_name, numprocs);
MPI_Finalize();
}
并遇到以下问题:
Catastrophic error: could not set locale "" to allow processing of multibyte characters
我真的不知道如何弄清楚。
