10th problem board after constraints

As a point of interest... my solver was probably unusual in that it applied a "constraint engine" to force moves for which there was no alternative, and to detect impossible situations. This is performed immediately upon problem load and also during the problem search. The attached file (which I think only opens in Firefox and Chrome) shows the 10th contest problem after initial constraint processing -- it is about 70% solved based on the constraint rules alone.

Code and Reports

I have put my solver up on Git Hub. I am about to addd my report there plus a jar and the shell script that runs it on the MTL computers. You can find it here https://github.com/fmstephe/Masyu-Puzzle-Solver I would love to read the reports from other people for the first challenge. I wouldn't expect it, but if anyone actually wants to read the source I will happily go through and tidy it up with comments etc. :)

How many cores?

How many cores will be available on the competition hardware? Will it be 40 cores with hyper-threading? The MTL lab seems to have a random collection of machines, ranging from 64 (assuming 32 core with HT) processors on the login node to between 40 and 32 on the test nodes.
