Promenade au Fond d'un Canal (Nov 19 2007)

As we warned, we had a major outage today to do some massive cleaning/organization in our server closet. It went well: with dozens of cable ties and power strips on hand we got rid of about 95% of the spaghetti dangling from the backs of the racks, spilling into several piles on the closet floor. But that wasn't the main reason for this outage. We also installed a new UPS to replace a broken one - so jocelyn and isaac are protected again, as well as put everything on some kind of power switch so that when we have our lab-wide outage it'll be easy to just flick things on/off (as opposed to reaching behind big, heavy things to yank plugs from the wall). With the power off we were able to move racks around to allow enough of a gap to finally get the old E3500 out of there (the late, great galileo) - it had been collecting dust in the corner for years. Speaking of dust, we also vacuumed.

But of course there were issues, which is to be expected when powering many massive servers off and on. We discovered jocelyn lost contact with its fibre-channel RAID (where the BOINC database resides). After some head scratching we realized this was due to fibre-channel support being lost in the recently upgraded kernel. We booted to an older kernel and it was fine. As I write this, both ewen (Eric's hydrogen database server) and thumper are doing forced checks of large disk volumes - that might take all night during which certain parts of our project will have to remain offline. We'll probably run out of work before too long. Apparently we need to turn off the forced checks. We also had some routing problems upon rebooting the Cisco but we quickly remembered that you have to do a "magic ping" to wake up the next hop and then traffic pushed through.

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

yikes, 155k looks good, but how much of that was leftover from gauntlet? if we can consistently maintain that then it's great!

 

[petrusbroder]

Thanks for the stats, Rattledagger. 😀
Yeah, it is a great drop from 200+ K to 155 K - and I fear that the drop in production will continue ... 🙁

 

[bryanW1995]

well, we were happy to get over 100k before gauntlet, so if we're even CLOSE to 150 then we'll be doing great. dajeepster is gonna do 10k all by himself, plus many of us are getting 20%+ more output just by using the optimized clients.

Thanks for the update, Rattledagger. :beer:🙂

 

[Assimilator1]

Thx RD

And yea we should still be quite a bit over our pre-race output 🙂

Btw I'm stress testing atm ,so no output from me until I find the right speed & stabilty for my Q6600 ,currently at 3.2GHz 🙂.After that I plan to run SETI on 2 cores.

 

[dajeepster]

I should be able to maintain 10k with no problem... I know I can get more, I just haven't figured it out yet.... I need to build two systems that are exactly alike and then just start messing with one to optimize the output.... I've been running the optimized clients too... but it doesn't feel like i'm taxing the systems enough.... for instance... on my c2s and my opteron systems... I can play games EQ2 and I just started with Crysis and it doesn't feel like my systems have slowed down... I can watch dvds with no problems also.... I just know I can get more out of my systems.

 

[bryanW1995]

boinc client is low priority, so if you're gaming etc it only uses the spare cpu power. I play games all the time with no probs at all on the e6750. some of my older systems sometimes have problems, however, depending on the game.

ok... thanks... i'll fix that right now... well.. try to anyways 😀

 

[bryanW1995]

RD or peter are your best bets to know how to do that. They're the boinc/seti masters 🙂

you're probably better off with it set to low priority, anyway. I got frustrated while running boinc on my cpu with f&h on my x1950xt b/c the system turned into a turtle. I prefer to keep boinc on all the time but I don't want it to keep me from actually USING the computer!

I wouldn't bother altering the priority level ,you'll gain virtually nothing except a sluggish OS & games😉 ,don't worry SETI will be using all spare cycles🙂
