Hi, everyone
I am a student and I am new to this LAM/MPI thing, but
I hope someone will help me with my questions.
I am currently building a beowulf cluster for my class
project. I have a lot of existing c and c++ programs
that only have EXE files but without the source code.
These programs are not MPI based, they are only
serial/single-process based. My question are: Can I
run these programs in a MPI environment? Will I see
performance gain from the output without re-compiling
the code?
Also, how about a JAVA program? How do I compile a
JAVA program with the MPI library? Do I have to do
this step or will the JAVA program automactically run
in the MPI environment without having re-compiled?
By the way, I am using MPICH2.
Thank you for your help.
Sincerely,
Yong
