[CIG-LONG] new install

[Matty Mookerjee]

Walter,

OK, I think I did what you wanted.  Here are the results:

matty at matty-ThinkPad-T530:~/Programs$ mpicc -c hello.c
matty at matty-ThinkPad-T530:~/Programs$ mpicc -o hello hello.o
matty at matty-ThinkPad-T530:~/Programs$ mpirun hello
Hello world from process 0 of 1
matty at matty-ThinkPad-T530:~/Programs$ mpirun -np 2 hello
Hello world from process 0 of 2
Hello world from process 1 of 2
matty at matty-ThinkPad-T530:~/Programs$

How does that look?

Matty

This all looks ok.  Lets try making sure that you can compile simple
MPI programss.  Try compiling and running the attached program with

mpicc -c hello.c
mpicc -o hello hello.o
mpirun hello
mpirun -np 2 hello

Cheers,
