    @lz77: There's also 2nd place prize ($1k).
    And you get to add the corresponding line to CV/resume and maybe find some job offers.

    Also for the competition itself its better if more people participate -
    depending on results it could be made permanent, like Hutter Prize.

    Can we use Huge pages for our submissions? I have created a submission the performance of which heavily depends on Huge pages, 8sec vs 13sec. Normally the kernel does it automatically using Transparent Huge Pages, but there is no guarantee. After a fresh reboot with a lot of free memory, Transparent Huge Pages work well, but after memory gets fragmented or filled up, the kernel cant use Transparent Huge Pages.

    Using Normal Huge pages can guarantee the use of 2MB pages but needs some simple extra commands (for Linux).

    echo 512 | sudo tee /sys/kernel/mm/hugepages/hugepages-2048kB/nr_hugepages # allocate 512 * 2MB
    time ./app options # run submission
    echo 0 | sudo tee /sys/kernel/mm/hugepages/hugepages-2048kB/nr_hugepages # release memory
    So i ask If we can ask for a certain amount of Huge pages for each submission, such that compression speed will be consistent.
