Note: peerReview does its work when a network connection is present. Modem users will notice that the client is not active while they are offline. A work unit is completed in 15 minutes, so it is possible for modem users to contribute useful work. The client supports some firewalls; it does not support users behind proxy servers.

The latest version of the PEER client is available as of April 22, 2009 for Windows. The client allows you to configure how much work your system contributes. PEER users' clients will update automatically.

DIMES passed 100 million measurements on June 16, 2005.

The client uses very little CPU and data bandwidth. It supports users behind firewalls. It requires you to have Java 1.4 or later installed on your system.

The project currently runs the following applications: peer-to-peer (P2P) sharing of legal promotional content (see some examples); improvement of search engine performance. In the future it will include other applications: benchmarking and monitoring of websites; distributed computing; rendering graphics; weather-related computing.

To participate in the project, download and run PeerFactor.exe. The PeerFactor client is currently only available for Windows. A Linux version should be available soon. The client is not configurable, to make it easier to use. The client runs at idle priority. The client can be used behind a firewall, but the firewall should authorize PeerFactor to use the maimum possible number of ports. The client currently only uses about 5% of available CPU to crawl and index websites for commercial search engines.

1st: Build up a database containing the dependencies between individual web sites and groups of web sites.
2nd: Collect statistical data about the structure of the web.

All of the projects results will be made publically available.

As of June 22, 2008, no work units are available for phase-1. The project owners are developing phase-2 and will issue new work units when that phase is ready.

The project, which began independently in 2001, was bought and ended by LookSmart on October 11, 2005. In its first incarnation it was "an open-source distributed Internet crawler." The client "crawled" websites to see which sites had changed their content, and updated a master search index in real-time. grub.org hoped to create and maintain the most comprehensive and up-to-date search index of the Internet ever, and provided update feeds of crawled sites to the public for free and to commercial search engines. LookSmart gave the following reason for ending the project:

Effective October 11, Grub.org, a project of LookSmart, will be shutting down its servers. LookSmart is focused on dedicating our internal resources to meet objectives that are core to our business strategy. As a result, certain elements that are no longer central to the business are being phased out.
