Use MPI to implement a threedimensional array communication

Use MPI to implement a three-dimensional array communication template

Solution

#include #include int main(int argc, char **argv) { int m = atoi(argv[1]); int n = atoi(argv[2]); int p = atoi(argv[3]); // if defined in stack... actually I\'m not sure it\'s defined in stack // in this way - shouldn\'t its size be known at compile time? // float a[m][n][p]; // in heap: float (*a)[n][p] = malloc(m*n*p*sizeof(float)); for (int i=0; i0) printf(\",\"); printf(\"%7.2f\", a[i][j][k]); } printf(\"\ \"); } printf(\"\ \"); } free(a); }
