Your home dept and research directories in /home/rai on mica. Note that this research directory will might be mounted different than your CS dept student home directory on all of these machines, so agate (if you should get a consistent environment. have one). Be sure to set up email forwarding if you need to.
The simplest way to run experiments across multiple machines is just to have a seperate terminal, emacs, and ocaml toplevel for each machine (or core, actually). If you find a better way, please post it!
Please leave at least one core unused on any CPU that you are running experiments on. Try the `top' command to check your CPU and memory usage. The load should be at most (cores-per-processor - 1) * num-processors.

agate is a general-use machine - don't do serious experiments on it.
The general-purpose research compute servers are:
c0.cs, c1.cs - dual quad-core Xeon E5320 1.86GHz, 16Gb RAM, 64-bit Fedora 8
c2 - c5.cs - dual-core PentiumD 3.2GHz, 4Gb RAM, 64-bit Fedora 8
ccluster@cs is the mailing list for coordinating their use. Send email before any long-running batches or periods of heavy use.
Let Wheeler know if you notice anything that works on cypress/katsura but not on the cluster machines.
"rup" is a convenient command for finding free machines.

lava.cs is the dept file server - don't run experiments on it! It's a 4-way 3GHz Xeon with 2Gb RAM.

You might want to subscribe to the CamlWeeklyNews to keep up with what's going on in the OCaml community.
Someone should look a this comparisonofparsergenerators and decide between menhir and elkhound.
For non-emacs users: top-level history and line editing can be achieved using rlwrap.

At CS dept, OCaml binaries are in ~ruml/bin/$HOSTTYPE/. ocamltop is a toplevel with many of the standard library modules (like Unix and Str) already compiled in.

A great place to start learning about OCaml is JasonHickey'sbook. Some people also like ocaml-tutorial.org.
There are lots of examples at the OCamlPLEAC page.
