# Note: "This setup requires the .NET Framwork version 1.1.4322..." 
# and they really mean 1.1, not 2.0 and not 1.0.
# Installed in c:/mpich2 to avoid spaces in paths.
# First get to the point where you can run cpi.exe example. May need to
# give yourself a login password.

# mpichs2-1.4 was added to my PATH
# note that the install step is needed to find the mpd and related executables
# in the mpich2/bin folder,
# since only the gforker version of mpiexec.exe appears in mpich2-1.4/bin
# folder after a make.
# The reason for making gforker the default is that mpd sometimes fails to
# operate correctly on user machines. gforker is limited to
# launching on a single node(multcore) but that is the most typical situation
# and makes it possible to use the bulletin board system on mulitcore desktops.
# If the parallel machine is a cluster environment then it will be
# necessary to use the mpd style for launching. i.e mpdboot on the master
# or mpd& on every node and then launch with mpiexe.mpd
# A test on a single node useing gforker is
# mpiexec -n 2 echo 'hello'
# A test on a single node using mpd is
# mpd&
# mpiexec.mpd -n 2 echo 'hello'
