Parallel Computing Workshop, Day 2

Today we put it together and wrote hybrid MPI / OpenMP programs in the morning - then had a tutorial on debugging parallel code in the afternoon. If you have never worked with a command-line debugger in UNIX, consider yourself lucky. Fortunately, Southern Man's code is naturally bug-free.

Here are three reasons why UNIX is not ready for general consumption:

nohup make FC=gff >& m_o.txt &
mpicc -g e-m-mpi.c -o e-m
tar zxvf GoBL2-1.13.tar.gz

If you understand any of this, welcome to the world of UNIX geekdom.
