Too Hot / Too Cold (Jan 24 2008)

I think I have the apache/tcp config in some kind of working order so that we won't suffer such wild dips like we had over the past couple of days. These pains were brought on by a confluence of three minor events: running out of work to send, waiting an extra precious day before enacting the database compression/backup, and reducing our backend to just one download server. You'd think the last item was the main culprit as we seemingly slashed our server capacity by 50%, but the real bottleneck is still the router (the new one still not config'ed yet - waiting on a new IOS image). The single download server (bane) can handle the traffic, but the apache config was such that when all the downloads started it the cpu load went up to 400. Basically, MaxClients was set way too high but this went unnoticed when only half the load was on vader and half on bane. Then I set MaxClients too low - we were dropping connections long before hitting other theoretical limits. Now MaxClients is set just right. Or right enough for now. We're still experiencing catch up "malaise" but it's a much smoother ride in general than yesterday.

I've actually been working on some scientific programming. With the new science indexes being built we're able to analyze some data to get an idea of the current RFI structure. Basically we're seeing the radar noise in the final data - the radar blanking signals are still being implemented so new data (once it finally starts coming in) should be far less noisy. I'm hoping this kind of work will inspire more scientific updates from the others (remember: I'm a math/computer geek, not an astronomer - everything I know about SETI/astronomy is from 10+ years of osmosis working here at the lab).

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...

Thanks for the SETI@home daily stats & tech news Rattledagger! :beer:

 

[Assimilator1]

Great output by us ,but Taiwan steam even further ahead!:Q

 

[Evadman]

Is there a thread somewhere that explains the new what that BOINC counts work? I just jumped on board 2 days ago with 4 machines, and I show 949 work done for Einstein and 1948 for SETI. I assume this equates to the 'Todays WD" column, and the AWD is the average work done?

Also, what does average work done actually count? My number is 176.89 for SETI, is that work done by hour or something like it? It can't be work done per day, I would be just under 1000.

<edit>
nevermind, found the wiki here.

Hi Evadman ,longtime no see!
(you're a senior mod now!:Q)

Last question 1st ,AFAIK AWD is RAC so that is an average over the past week as alluded to by that excellent BOINC wiki you found ,thanks for that btw.

I think the 'work done' you mentioned is your total credit which is not the same as 'todays Work Done' which is daily output (excluding the very 1st day you ran it).
And yes AWD is Average work done.

Welcome back to The search
What PCs are you running it on?

 

[bryanW1995]

I think that awd is actually more than just the past week, but the farther back you go the less weight it has.

Yeah, I think that explains it well enough. Although even after reading it i'm still confused, thats a long winded explanation.

Thanks for the stats!
