This is here for future reference:
$ diff driver_rand.c driver_rand.c.orig 
61,68c61,64
<       ndim = 2;
<       if((fp=fopen("stdin", "r"))==NULL){
<          printf("Cannot open file. Setting to default nx=ny=nz=128, ndim=2, 
n=1.\n");
<          nx=ny=nz=128; n=1;
<       } else {
<          fscanf(fp,"%d %d %d %d %d\n",&nx,&ny,&nz,&ndim,&n);
<          fclose(fp);
