MPI_Allreduce on structure of doubles. Portable?
|
| |
Hello,
Consider something like this:
---
typedef struct TS {
double a,b,c;
...
...
S x,y;
...
MPI_Allreduce(&x, &y, 3, MPI_DOUBLE, MPI_SUM, MPI_COMM_WORLD); ---
Is the above code completely portable (without using MPI_Type_struct and all)? Thanks!
JS

Basic question about MPI
|
| |
Hello,
I have a very basic question about MPI.
I have a computer with 8 processors (each with 8 cores). What is the difference between if I run a program simply by "./program" and "mpirun -np 6 /path/to/program" ? In the first case does the program just use one processor of the 8? If I want the program to use all the 8 processors at the same time, then I have to do with mpirun?... more »
