Hrm.. I was wrong with what I said before (that's what I get for trying
to respond from my parents' house).   Check out the file
/etc/beowulf/config   There is a line that starts with
'kernelcommandline'  After that is the options that are passed to the
kernel.  Try adding the mem= to the end of that line.

swap partitions never show up with 'df'.  Use a command such as 'free'
to see see how much swap space the node has.  You should be able to use
that number to see if your swap partition is being recognized.

Also, make sure you edit /etc/beowulf/fstab to indicate where your swap
partition is as well as what your other partition is and where you want
it mounted.
