请问DMA模式中RANK_MODE行集合模式是什么呢？

如题。请问各位老师，如果想要使用，mask应该怎么写呢？ 如果能有相关代码示例是最好啦，万分感谢～
还有15年JCST上的文章《Cooperative Computing Techniques for a Deeply Fused and Heterogeneous Many-Core Processor Architecture》中提到的Array Pattern是指什么呢？ 应该怎么使用呢？就是文章Fig.4 (g)

大概应该是athread_get(RANK_MODE, src, dst, len, &reply, mask, stride, bsize)
比如athread_get(RANK_MODE, src, dst, 1024, &reply, 0xff, 0, 32)应该是: len=1024, mask=0xff, bsize=32
可以获取1024B数据，其中从核0获得0-32B, 256-288B, 512-544B, 768-800B, 从核1获得32-63B, 288-320B, 544-576B, 800-832B, 以此类推。

例子：

#ifdef MPE
#include <athread.h>
#include <stdio.h>
extern SLAVE_FUN(rank_mode)(double *);
int main(){
  double data[128];
  int i;
  for (i = 0; i < 128; i ++){
    data[i] = i;
  }
  athread_init();
  athread_spawn(rank_mode, data);
  athread_join();
  athread_halt();
}

#endif
#ifdef CPE
#include <slave.h>
void rank_mode(double *data){
  if (_ROW > 0) return;
  double d_local[16];
  volatile int reply;
  athread_syn(ROW_SCOPE, 0xff);
  if (_COL == 0){
    reply = 0;
    athread_get(RANK_MODE, data, d_local, 1024, &reply, 0xff, 0, 32);
    while (reply != 1);
  }
  athread_syn(ROW_SCOPE, 0xff);

  int i;
  for (i = 0; i < 8; i ++){
    athread_syn(ROW_SCOPE, 0xff);
    if (_COL == i){
      printf("%d:", _COL);
      int j;
      for (j = 0; j < 16; j ++){
        printf("%f ", d_local[j]);
      }
      puts("");
    }
  }
}
#endif
