You'll need to look at the individual tool documentation. In general, many
tools uses multiple cores, few use MPI for multi-node computing.

If you've set up Galaxy to use a job scheduler (e.g. SGE/PBS), multiple nodes
can be used. Multiple nodes will be used on the cloud:

Automation via the API is possible; unfortunately, most API documentation is in
the Py/Sphinx docs for now, so you'll have to dig and/or use the sample scripts

Roadmap at a very high level is in this presentation:

The framework is being separated from tools. The best place to look for tools
is in the toolshed, where there is an abyss wrapper:

There is active work on cancer tools for Galaxy. Keeping an eye on the toolshed
is a good idea here.
