BOINC (Berkeley Open Infrastructure for Network Computing) is a software system that makes it easy for scientists to create and operate public-resource computing projects. It supports diverse applications, including those with large storage or communication requirements. PC owners can participate in multiple BOINC projects, and can specify how their… (More)
Millions of computer owners worldwide contribute computer time to the search for extraterrestrial intelligence, performing the largest computation ever.
"Volunteer computing" uses Internet-connected computers, volunteered by their owners, as a source of computing power and storage. This paper studies the potential capacity of volunteer computing. We analyzed measurements of over 330,000 hosts participating in a volunteer computing project. These measurements include processing power, memory, disk space,… (More)
Volunteer computing projects use a task server to manage work. Clients periodically communicate with the server to report completed tasks and get new tasks. The rate at which the server can dispatch tasks may limit the computing power available to the project. This paper discusses the design of the task server in BOINC, a middleware system for volunteer… (More)
The Continuous Media File System, CMFS, supports real-time storage and retrieval of continuous media data (digital audio and video) on disk. CMFS clients read or write files in “sessions,” each with a guaranteed minimum data rate. Multiple sessions, perhaps with different rates, and non-real-time access can proceed concurrently. CMFS addresses… (More)
Cloud Computing has taken commercial computing by storm. However, adoption of cloud computing platforms and services by the scientific community is in its infancy as the performance and monetary cost-benefits for scientific applications are not perfectly clear. This is especially true for desktop grids (aka volunteer computing) applications. We compare and… (More)
The majority of the world's computing power is no longer in su-percomputer centers and institutional machine rooms. Instead, it is now distributed in the hundreds of millions of personal computers all over the world. In a few more years, other consumer devices like game consoles and television set-top boxes may comprise a large fraction of total computing… (More)
Computers continue to get faster exponentially, but the computational demands of science are growing even faster. Extreme requirements arise in at least three areas.
