Immediate nostalgia activated. I ran this on a Pentium machine (I think) at home, still living with my parents. Sometimes I yearn for the optimism and relative naïveté of those times.

Pentium 3 in a crusty Compaq with a 5.25" bigfoot hard drive.

Those were the days


This paper describes the front end of SETI@home and provides parameters for the primary data source, the Arecibo Observatory

Most of this data was recorded commensally at the Arecibo observatory over a 22 yr period

Interesting as Arecibo collapsed in December of 2020. It sounds like they have a lot of data to still churn through.


>Most radio SETI projects process data in near real-time using special purpose analyzers at the telescope. SETI@home takes a different approach. It records digital time-domain (also called baseband) data, and distributes it over the internet to large numbers of computers that process the data, using both CPUs and GPUs.

Definetly something going on here I'm not following.

>SETI@home is in hiberation. We are no longer distributing tasks. [0]

Is this paper really old or something? I would love to turn on my clients again :D

They went into hibernation, in terms of accepting new inputs, several years ago. They had more data than they could handle and switched to just analyzing existing data and final reports.

With the final analysis of this project complete, I do wonder if there's a way to bring it back with distributed agents doing the part that was so time-intensive for researchers that they had to kill it.
