It's the Little Things... (Sep 17 2007)

This was a rough weekend - but all due to the collision of a lot of minor things which, by themselves, would have been relatively harmless. Of course, I was sick with a cold all weekend and had rehearsals and shows with three different bands on three different days, so I couldn't do much anyway except check in and point things out to Jeff who dealt with most of it.

Anyway, early in the weekend there were some lost mounts on bruno (our main BOINC administrative server). Why does autofs lose mounts so readily? And why is it unable to get them back? This happens from time to time, with varying effects. In this case it caused various cronjobs to hang, then fill up the process queue, which ultimately brought the machine to a standstill. I discovered this in the evening and told the gang. Dan actually came up to the lab to power cycle the machine which cleared some pipes, but the fallout from this was extensive. Various queues were backlogged and certain backened processes were not restarting.

Upon the reboot of bruno, its RAID volume (which contains all the uploaded results) needed to be resync'ed. Not sure why, but it ate up some CPU/disk I/O for a while and then was fine.

Anyway.. the bruno mishaps caused gowron (workunit file server) to start filling up. I deleted some excess stuff to buy us some time, but there wasn't much we could do except keep a close eye on the volume usage until the whole backend was working again. Meanwhile splitters were stopping prematurely and not restarting (continuing mount problems). And the old mod polarity issue reared its head when we were low on work to send out (you can read more about that in some older threads).

Then, of course, we ran out of work to split. I believe several of our multibeam raw data files are being marked as "done" prematurely due to various issues over the past couple of months. Plus we haven't really had a solid couple of "normal" weeks to get a good feel of our current burn rate. In any case, Jeff got some more raw data on line earlier this morning.

Oh yeah.. we lost a disk on our internal NAS which contains several important volumes, including a subset of our download directories, so that slowed down production for a while as one of thirteen spare drives was pulled in and sync'ed up.

That's basically the gist of it. Back to work.

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

where do you go to find these stats? I tried to post some the other day but they just showed how everyone was doing, they didn't show overtake stats and whatnot.

You won't get the overtake-dates and so on directly, for this you'll need to do some "post-processing" of the data.

Basically, it's to grab the stats from one of the BOINC-stats-sites, personally I'm using Toby Murray's stats (KWSN) since don't need to "filter-out" so much garbage that is needed for some of the other stats-sites... Select top-50 on the stats-site, copy the data to Excel, re-copy but "paste special" and "paste only values", sort data after total credit, open-up yesterdays stats and paste-in neccessary data, check if any teams has switched places, move RAC and "todays stats" to another location, remove unnessesary columns, name 3 specific cells (Anandtechs RAC, total and today), and paste-in all the formulas doing the calculation and most of the formatting from yesterday.

After this, only one "extra" step is needed, copying to Notepad and removing all "tabs" that has been included.


From firing-up web-browser until verified the stats was posted ok takes 5-10 minutes, depending on how many News-pieces there are, and how slow the forums is and so on...
