Hello, i have to do homework from MPI and i have no idea how to start, maybe some one can guide me how to make it work
Original problem is from Parallel Programming with MPI book (Peter S. Pacheco )
If you have an implementation of MPI that runs on a network of workstations and the workstations are not all using the same 
disk for their home directories, use the file I/O functions to write an rcp function. It should take as input the name of a file and
two process ranks. The first process has access to the file. The second process should create a copy of the file on it's local disk
under the same name
So can i basically use single computer, and with one process open file, and with other process copy to other disc location ? Or how that should be done ?

Hi
You could use omp, the OS should take care of dup file handles, each section gets a processor on the cpu




#include <omp.h>

#pragma omp sections
{
#pragma omp section
{
File open temp.txt
}

#pragma omp section
{
File open temp.txt
File open temp1.txt
}
}
