Intel's Superchilled Test Rig

Posted by timothy on from the now-that's-offsides dept.

Barence writes "Last week, PC Pro issued a challenge to see whose PC could render a 3D graphics benchmark in the shortest time. The competition was won by an entrant with a rather unfair advantage: Intel. The processor giant's superchilled rig is overclocked to nearly 5GHz. As PC Pro explains: 'The rig itself uses phase-change cooling: in other words it's attached to a chuffing great freezer, which I believe is the big box on the right of the photo. That yellow meter with the readout is showing the temperature of its output: yes, that's minus 40 degrees Celcius.'"

    -40C is also -40F ... so -40 it is

    I had a 30 minute look at the source code. It's clearly optimized for shortness, not for speed.
    There are some obvious performance no-gos, see lines 44-45, using a double variable as a loop counter.
    Performance depends to a good extent on the erand48 implementation and whether OpenMP knows that erand48 is MT-safe.
