Wat is Seti@Home ?
Wat is SETI@home?
SETI@home is de naam van een wetenschappelijk experiment dat computers die via het internet met elkaar verbonden zijn, inzet om buitenaardse intelligentie op te sporen. U kunt hieraan deelnemen middels een gratis computerprogramma dat radiotelescoop-data download en analyseert.
BELANGRIJK: wekelijks driedaagse server outage
Weekly Outage and Initial Catch Up
Every Tuesday morning (Pacific time) we begin a 3 day data distribution outage to focus on science processing and development plus any needed systems maintenance. The upload/download servers will be offline during this time. The web site (including the forums) will only be offline during the database maintenance and backup portion of the outage. On Friday, you may experience connectivity issues as the servers catch up with demand.21 Sep 2010 17:01:37 UTC

I'm starting a thread to let people know what's going on with the mork (our boinc DB server) issue.
As most of you know, mork will sometimes hang, requiring a power cycle to boot. There are no footprints as to what causes this. So we strongly suspect hardware.
Mork has a sister machine (mindy, of course) that never really worked (both are donated, used, HW). So mindy is mork's parts machine. This is a little dicey because we don't know why mindy did not work.
The RAM in these machines are arranged on 4 daughter boards. Last week we swapped all four of mindy's identically populated memory boards into mork. But at least one of the "new" sticks was bad because mork then showed differing amounts of memory across subsequent boots.
So we returned mork's original memory and ran the first three memtest tests. They showed no error. The final several tests are very time consuming and we may or may not do them, as mork's OS is down for these tests.
Today, we swapped mindy's two power supplies into mork. This is not because we strongly suspect the power supplies but because this is an easy exercise.
If mork hangs again, we are likely to replace the entire machine. Further component testing is becoming too cumbersome and time consuming. And after all, we now have the funds to do this because your very generous donations (thank you!!!).
