Question

I have a program that is been implemented in C++ which I now want to add MPI support. There is an MPI binding for C++, with namespace MPI and everything.

In my case I have a specific object that is suitable to be the parallelized process into the cluster.

My questions are:

• Has anyone done something like this before? Can I get some advices on how best to implement this?
• How do I initialize MPI inside the constructor? After initializing MPI inside the constructor of the Class, will all the intermediate calls be parallelized too?

For example:

MyClass obj;

x = x; //this will be parallelized ?
onj.calc();

y = x++; //this will be parallelized ?

z = obj.result();

I would really recommend picking up the Gropp MPI Book, it really helps for basic MPI!
