Detailed Description

Parallel SIMulator used by class mdp_communicator.

Attention: under MDP and/or FermiQCD this is already Instantiated inside class mdp_communicator.

Example:

    int main(int argc, char** argv) {
       mdp_psim node(argc,argv);
       int a=3, b=0;
       if(node.id()==0) node.send(1,a);
       if(node.id()==1) { node.recv(0,b); cout << b << endl;
       return 0;
    }
    

Compile with

       g++ [filename] -o a.out
    

and run with

       ./a.out -PSIM_NPROCS=2
    

Output should be 3.
