Slowness (Jul 08 2008)

Weekly outage day (to compress/backup BOINC database). It lasted a little longer than usual due to some confusion - unbeknownst to me a recent web code update was made that broke the "stop_web" mechanism which keeps the database quiescent during the outage. It's also taking a long time to recover. Not sure why but we'll see if the clog pushes through. I took advantage of the outage to move server anakin into the closet. We also upgraded the RAID card BIOS to see if that fixes our minor issues with ptolemy's current hardware RAID setup. Well, it's logical volume initialization is still way too slow, but maybe we'll live with that if all future resync's are fast.

Just wrapped up the scoring meeting I mentioned yesterday. The bottom line being our current scoring algorithms for individual signals (spike, guassians, pulses, triplets) are sound, the multiplet scores (interesting groups of signals of a single type) are 99.9% sound, and metacandidate scores (of single sky pixels containing "candidates" like indiviual signals, multiplets, or stuff observed from previous SETI project, as well as interesting celestial objects) are still way up for debate as this is where individual philosophies differ, but we'll probably just go with the easiest solution (multiply all the candidate probabilities together) and see what that list looks like. Jeff will write all this up. Maybe we'll even have a science newsletter.

Jeez... still having a hard time recovering...

Appart for Anandtech's stats, it shows how much more/less than Anandtech.
Also shows based on Average Work Done how many days for Anandtech to overtake the team, or be overtaken by a team behind...


There's currently some sort of server-problems, with among other things Transitioner being 10-hours backlogged, and it doesn't seem much work goes out...

With the server-backlogs, the user-stats wouldn't make much sence, so not included...
 
Seems the backlog is clearing up. I got a good dump of points today. I was unhappy that most of my machines had no work this morning though. All is running fine now for me.
 
I just rejoined SETI for some 80,000 creds to crunch. I'm pretty much behind on the SETI stuff, though. Now, how often does SETI have downtimes? I ask because I haven't been able to access my account for about 24 hours due to server maintenance. Is that a routine job or an exceptional one?
 
exceptional. Something funny is going on. Hopefully they do a blog update today so we're not totally in the dark.

Welcome back to the search 🙂, did you mean you are starting from 80k or are going to crunch 80k?

Re outages, 24hr ones are fairly rare, but every week they do server maintenance which means outages of 3-4hrs IIRC.

Thx RD 🙂
 
Cool 🙂 ,what are you crunching on these days?

Btw their are some good optimised clients about for anything that can run SSE3 on, their are some for SSE2 too but I don't know how much of a boost they give.
 
sse2 gives only ~ 10% boost, but the v8.0 science app on sse3 or greater machines is pretty close to 100% improvement 🙂 just be careful of your oc, I still need to go to my mom's house to back hers down a few notches to keep it stable...
 
lol your mum's got a quad?😎, is that so she can open her emails that little bit quicker?😉
My mums still got the Duron 1200 I built her about 7yrs ago! (she's still crunching SETI....slowly😉).
 
@Assimilator1: I got a Q6600 (stock) crunching SETI with an optimized client. Produces about 3500 creds a day! :evil: The boost from these clients is pretty big from what I can tell. 🙂
