[mpich-discuss] MPICH2 not installed or unable to query the host

[Mis Nat]

I have a simple HelloWorld  program which I've tried to run for the
begining. I run cmd.exe as Administrator and run my program with "mpiexec
-n 10 HelloWorld.exe". The problem I have is that on A-Computer all
processes are on A-Computer and if I try to run it on B-Computer all
processes are on B-Computer. My final goal is to write QuickSort algorithm.
But first I have to be sure my program will run on both computers, because
I'm going to analyze the time. I assumed that I need A-Computer highlighted
green and that will solve my problem..
