I am trying to build parallel computation system with Master Machine and Helper Machine.

Based on the literature review I get:

  1. Install mpich2 from sudo apt-get install mpich2

  2. Make a shared folder and install mpich-3.0.4 in this folder so that the Helper Machine can access it

Is there any different within this two approach? What will happen if I do both? Would it be any conflict between mpich2 and mpich 3.0.4 if I install both? Which one is more efficient?

Thanks in advance
