The University of California at Berkeley (USA) announced the termination of the famous SETI @ Home project. Formally, it does not close, it only freezes, but in fact the organizers admit that it has exhausted itself. Starting from March 31, 2020, participants will no longer receive assignments, but will be able to continue communicating on the project forum. And, probably, they will receive offers to take part in similar programs in the field of cosmology or the study of pulsars.
The SETI @ Home project was launched on May 17, 1999 to combine the computing power of the PCs of many contributors from around the world to analyze data that would aid in the search for extraterrestrial intelligence. Radio telescopes annually collect huge amounts of data, for the processing of which no agency can obtain a supercomputer, and even for 21 years. Therefore, scientists from Berkeley in 1999 took the path of computing distribution, and by 2011 the BOINC computing network they created was recognized as the largest in the world, becoming the official record holder.
At the peak of the project's development, it had more than 5 million participants, the number of active hosts exceeded 527, 800 units, and the total computing power reached 5, 428 petaflops. Users could choose how much work to take on, allowing their computers to complete project tasks only when idle or at full capacity. All this led to the fact that after 21 years there was ... nothing to process.
According to the organizers, all the key volumes of data have already been processed, now we need to focus on analyzing what was found among them. This is a simpler task and the help of millions of enthusiasts from all over the world is no longer required. In addition, administering a network as large as BOINC is overwhelming. Therefore, the project was transferred to the freezing stage. And one more news without a positive color - for all this time we have not found aliens.
