i want to know how many of computers would seti have to have to make the signal in real time??? because it seems to me even if you got a signal today, it would be a year before we can process it to even know we got the signal. my wish is for seti in real time!!!

As far as I know they record the data from the dish at Arecibo and store it on hard disks before transporting to Berkley (they used to use tapes). They then split it from its 50Gb chunks into smaller work units for us to crunch.

They would need to have a direct link with really good bandwidth to just get the data from the dish direct to Berkley. The other issue is the dish does other things apart from SETI.

If you look on the Server Status page, under Splitter Status you can see which data they are splitting, the last time I looked they were splitting Feb 2008 data plus some older ones, so its not that far behind.

What's the difference if we work on todays work, or work from 10 years ago? The signal we find will be over 10,000 years old, even 100,000 years or more. It's not like we can answer it tomorrow. The civilization may now longer even be alive.

Before the Multi Beam antenna went on line, we were actually processing tasks faster than they were comming in (we were working through the backlog). I am not certain of the current rates. The last things that were crunched before the multi beam data became available were crunching tapes that were too noisy to do when we were not keeping up, and re-crunching some data that had originally been crunched with much less capable applications. When multi-beam came online, I believe that the backlog of any work to do at all was under a week.

Those 10K, 100K is at the speed of radio waves, meaning they will be light years away. We are not going to have the ability to even research much for many years later.
