What is SpareCycles.org?

SpareCycles.org is an experiment.

SpareCycles.org is a market for spare computing cycles.

SpareCycles.org is an advertising board. Computers advertise their spare cycles. Taskers advertise their tasks. Escrows advertise their dispute resolution services.

SpareCycles.org is not a business. It holds no customer money. It charges no fees. It is done for the love of empowering people with computational cycles on-demand at a price near that of electricity.

What are the economics?

From oil exploration to media processing to scientific simulations, there is always need for more computing power. Even the top exascale supercomputers are not enough. Attending conferences at my employer Argonne National Laboratory, my office across the parking lot from the third largest supercomputer in the world, illustrated the monumental effort to meet this unending demand.

Supercomputers and cloud computing companies must cover infrastructure, operating costs, and salaries. Our infrastructure is personal computers which are already paid for. Our costs are electricity and optional escrow fees. Our salaries are zero. Furthermore, our market is worldwide and has zero barriers to entry -- perhaps a perfect market.

Fees are whatever the computer and tasker agree upon, along with the optional escrow. To promote market-depth, we ask market makers to deduct a 0.5% fee from market takers.

What should taskers consider?

What should computers consider?

What should escrows consider?

How are disputes handled?

How do I perform account administration?

Site administration is performed by signing a request. Similar for communicating with escrow agents. The format of these requests is being developed.

What about decentralization?

We are still centralized running on SpareCycles.org servers. We plan to build a concurrent decentralized version if we meet our funding goals.

What crypto-currencies do you support?

Whatever the tasker supports.

Why does the website look so outdated?

To minimize browser workload, and to minimize security risks from javascript.

What is your privacy policy?

Please do not send us your private information.

What are the licenses or restrictions of SpareCycles.org?

We will open-source everything if we meet our funding goals.
