GPU load testing on Linux

[j4cbo]

I've been struggling to find a way to do a maximal load test on my video card. The canonical program, RTHDRIBL, doesn't work on Linux; the only other option seems to be a high-end game of some sort.

But I found this yesterday: GPU Quaternion Ray Tracer

It's a massive GPU load (brings my 7800GT to a crawl, with practically no CPU usage whatsoever), and really tiny in size. Thought some people might find it useful...

Here's the Linux binary (also includes the Windows .exe), with permission from the author.
