This was my reaction too. What kind of university scoffs at someone using what started out as an academic operating system? Hell, my community college had a supercomputer node running some variety of Unix (I forget which), which we hacked on for a short while as part of our studies.

IT support shouldn't have to directly support Linux but the network should be platform agnostic at the least.

Your parallelized program took ten times as long? What were you doing?

Although I will say that when we were doing parallel programming, we did have access to Sharcnet nodes, so perhaps you were more limited.

Here's one at my workplace...

What takes hours on this system could take weeks on a "super-powerful single machine".

So if four universities can have a dencent computer in Canada, others probably do too

We Do! It's called Sharcnet:

The primary Beowulf clusters are deployed at the University of Guelph, McMaster University, and the University of Western Ontario. Smaller development clusters will also be deployed at the University of Windsor and Wilfrid Laurier University.

I believe they will use high speed networks of Linux based Beowulf clusters (actually clusters of clusters of clusters). Ontario has already established SHARCNET between a number of Universities with a total of over 500 COMPAQ Alphas (mostly four-processor, 833Mhz, Alpha SMPs) and some Pentiums, all running Linux. A press release from last year gives a good overview of the project, already first in Canada and the 11th most powerful academic computing system in North America. I believe the Canada wide project will essentially form a cluster of these cluster of clusters.

SHARCNET has been up and running for a while and last year accounted for about 27% of supercomputing power in Canada (half of all supercomputing power in Canadian universities), with three sites on the Top 500 list and total power exceeding institutions like Cambridge, Princeton, Cornell and Caltech. There's loads of information available about the hardware and software used at each facility, as well as CPU load and usage statistics at members sites like these status charts from the most powerful individual site, at the University of Western Ontario. As for applications, a number of researchers are already using the system for a variety of projects across science, engineering, and economics.
