I think you have a misunderstanding of what Ganglia is -- it's a
monitoring tool for clusters. It reports various statistics for what
is happening on your cluster.
LAM is an implementation of the MPI standard, which allows
specifically-written applications to run in parallel, meaning that they
can be run on multiple nodes in a cluster (for example).
The services that you mention (postfix, procmail, spamassassin, myself,
apache) can be cluster-ized, but not typically using MPI (at least, I'm
not aware of any of them using MPI to be cluster-aware; MPI is probably
not quite the right technology for them to be parallelized). You'll
need to do some googling around to find other resources for
cluster-izing those kinds of services.
Hope this helps.
