Also, keep in mind that the actual testsuite used to score the entries is different than the sample testsuite provided on the File Exchange. Thus, the exact amount of work the code has to do might be a bit different.

Nick,
We do not open a MATLAB pool, so PARFOR will act the same as FOR wherever it's used. As always, only base MATLAB functions are available to be used in the contest. While the official time we measure won?t see any benefit from using PARFOR, it might help a user develop/test code more quickly if they have the Parallel Computing Toolbox available.
Good luck on the home stretch!
