20 years and counting!

SETI@Home News - Fri, 2019-05-17 17:39
Happy Anniversary! On this date in 1999, SETI@home came online. Since then millions of our volunteers have helped us sift through petabytes of data from multiple radio telescopes. ET still hasn't shown up to the party.

We're not discouraged. We're able to examine less than a tenth of a percent of the radio spectrum, over only 1/3 of the sky and a limited number of additional stars. But our capabilities are increasing every day. In 1999 it took up to a week to process a single workunit on a home PC. Now, on a machine with a GPU, it might only take a few minutes to do a far more detailed and more sensitive analysis. Who knows what the next 20 years will bring?

Long Outage Today

SETI@Home News - Wed, 2019-04-10 00:57
We had to recover the master database on oscar from a backup taken today on carolyn. Oscar is now back to being the master DB and carolyn is once again the replica DB. Things will be a bit slow as the database becomes resident in memory.

Another crash

SETI@Home News - Wed, 2019-04-03 00:14
This time the primary database machine crashed and hasn't automatically recovered. We've fallen back to the replica machine, and the only symptom should be a few extra hours of outage.

I'm glad we have the replica.

New SETI Perspectives article

SETI@Home News - Tue, 2019-03-12 21:18
Richard M Lawn has posted another interesting article to the SETI Perspectives forum. This one is about the mysteries of Fast Radio Burst (aka FRBs), possibly some of the most distant explosions ever seen.

We're back up.

SETI@Home News - Thu, 2019-03-07 00:51
Hopefully there won't be any further problem.

Our attempt to upgrade the memory on Oscar (the BOINC database machine) and Carolyn (the replica database) took a bit of DIMM swapping to find pairs of DIMMs that worked. Carolyn is still short two DIMMs (32 GB), but we didn't want to extend the outage any further to try to get it up to the full 192 GB.

We might try to max out Carolyn during the outage next week.

[edit]And as is usual after a long outage, we've got a large number of hosts out there starving for work. It'll take a little while before "no work" messages start to get less frequent.[/edit]
