mpirun and "test"

I had a great revelation today! I was unable to run my MPI program named "test.cpp" using mpirun (Open MPI) 1.3.2

I was stuck up for 3 days!

I couldnt find any problem with my code. I tried, tried, tired. It didnt work!

I changed the name of file to "client.cpp"

Alleluia! It worked. It seems that "test" is a reserved word/file in MPI. Dont mess with it, ever!
