Distributed computing stories in the tradition of volunteer grids (like SETI@home and World Community Grid) aren't terribly common, so I usually take notice of them. This week, an item in Digital Trends alerted me to the existence of a new cycle scavenging startup, CPUsage.

The company, based in Portland, Oregon, operates kind of like the volunteer grids, except it pays users for their "extra" compute power, then collects and reallocates the cycles. The loosely-coupled system is a good match for inherently-parallel workloads and the company is seeing demand for visualization-related jobs like video encoding.

"The idea is that there are so many computers around the world that sit idle most of the day," states co-founder Jeff Martens in the Digital Trends piece. "In the U.S. alone, there are 250 million PCs – and most of us let those computers sit idle most of the time. And even when we do use them, the average person is using about five percent or less of the CPU's capabilities."

"We harness that unused processing power and we repurpose it and sell it to companies with high through-put and high performance needs."

Martens and co-founder Matt Wallington, a 10-year veteran of Intel, explain that the concept of harnessing unused cycles over the Internet came out of NASA originally and was popularized by the SETI@home program – a Space Sciences Laboratory project that uses public computers to look for signs of intelligent life outside Earth. (SETI stands for the Search for Extraterrestrial Intelligence.) The impetus for CPUsage came when Martens, who was then working for an electronic design automation firm at the time, was listening to his friend, a Sun Microsystems employee, bemoan the amount of time required to run simulations.

Martens figured that if employees of a major HPC company were in this predicament, there had to be a better way. His thoughts soon turned to virtually-unlimited pools of idle compute cycles, and the idea for the company was born.

While the startup has already raised $1 million in seed funding thanks to Bay Area investors, the founders are managing the company's growth carefully. Nevertheless, the execs report that supply-side interest is already sky-high with a waiting list in the thousands. Louisiana State University is one high-profile partner and offers a good illustration of untapped computing power. Its computer labs are open and powered-on 20 hours a day, but only used for an average of three. CPusage will allow the university to recoup some of that wasted power and potential.

As with similar programs, the duo say the software is unobtrusive and all users have to do is download it, take care of a few settings, the rest happens automatically behind the scenes. The current release is limited to Windows clients, but Linux and OS X versions are being looked at.
