Scientists are looking for narrow-bandwidth radio signals from space that are not known to exist in nature.
It requires huge amounts of computing power, so the program broke the data that into chunks that an ordinary PC could handle. Since it was a screen saver, it runs when volunteers are not actively using their machines.
It created a huge, virtual supercomputer, the group said.

Thanks to the many volunteers who have helped crunch data for SETI@home in the last two decades. On March 31, the project will stop sending out new work to users, but this is not the end of public engagement in SETI research. pic.twitter.com/P0t0v8w7n4

“We hope that other UC Berkeley astronomers will find uses for the huge computing capabilities of SETI@home for SETI or related areas like cosmology and pulsar research,” the post said.
The group thanked volunteers for their 20 years of help and said the SETI@home website and message boards would continue to operate.
The post did not say if they have found any alien life.
