ITK 10th Anniversary: 24 HOURS to DASHBOARD FEST 1.0 : Nov 5th 9pm EST : Parallel Builds

[Luis Ibanez]

Gaetan Lehmann pointed out that we can take advantage of the
DASHBOARD FEST 1.0 to track (and hopefully solve) an issue
with the parallel build of ITK.

In summary:

* ctest makes possible to use all the cores of your computer
   when building a project and when running its tests.

* you take advantage of this functionality by using the "-j" option
   in ctest. For example, if you have four cores, then you can
   use them all, by calling:      "ctest -j4  -D Experimental"

It will be great, if tomorrow and Friday, as you submit builds
to the ITK Dashboard, you use the "-j" option of ctest.

For more details, please see:

     Please let us know if you have any questions,


              Thanks


                   Luis
