New and Improved SETI@home will Form the Backbone of Distributed Computing Network

Amir Alexander • September 25, 2003

SETI@home and BOINC are gradually converging, and the benefits for both are substantial. While SETI@home enjoys the increased flexibility of the BOINC platform, it brings to BOINC something of inestimable value to a distributed computing project: millions of SETI@home users, willing to use their computers' processing power for the advancement of scientific research.

Analyzing the Reobservations
