c - MPI_Reduce 指针

Question

你能帮我处理 MPI_Reduce 吗？我收到这样的错误

In: PMI_Abort(1, Fatal error in PMPI_Reduce:
Internal MPI error!, error stack: 
PMPI_Reduce(1284)....................: MPI_Reduce(sbuf=0x7fffcd0d0ae0, rbuf=0x7fffcd0d0af0, count=400, MPI_LONG, MPI_SUM, root=0, MPI_COMM_WORLD) failed
MPIR_Reduce_impl(1090)...............: 
MPIR_Reduce_MV2(1173)................: 
MPIR_Reduce_two_level_helper_MV2(887):

MPIR_Localcopy(386)..................: memcpy arguments alias each other, dst=0x7fffcd0d0af0 src=0x7fffcd0d0ae0 len=3200
)

这些是所有进程的代码

#define binsperdegree 4
#define totaldegrees 64

long int TotalCountDD;
long int tDD;

int nr_of_bins = binsperdegree*totaldegrees;  
int hgram_size = nr_of_bins+1;

long int *histogramDD; 
long int *totalDD;

对于根进程

totalDD = (long int *)calloc( tDD, sizeof(long int));
MPI_Reduce(&histogramDD, &totalDD, tDD, MPI_LONG, MPI_SUM, 0, MPI_COMM_WORLD);

对于非根进程

totalDD = (long int *)calloc(tDD , sizeof(long int));
MPI_Reduce(&histogramDD, &totalDD, TotalCountDD, MPI_LONG, MPI_SUM, 0, MPI_COMM_WORLD);
