[SETI@Home] hitparade van 25 juni

[Anoniem: 159695]

Goedemorgen,

Voor de meeste mensen geldt dat het weekeinde zo meteen weer begint, voor mij persoonlijk begint de werkweek nu pas..... dus even relaxed wakker worden en het echte dramaandag gevoel beleven.

Er zijn weer wat mooie mijlpalen weg te geven.

Van harte AmeComputers, Revel@tion, Dennis, Aplo en jurgen met de behaalde palen.

Onze FOTD is vandaag duidelijk Dr.Drax die met een enorme plaatsstijging de daily top 30 komt binnenstormen.

Zoals BP gisteren al zei kom het UK BOINC Team ons gelievde plekje overnemen.
Dat kunnen we natuurlijk niet veroorloven en verzoek dan ook iedereen om nog even wat extra te assimeleren of desnoods van andere projecten weg te halen .

Ik wens jullie een mooie dag verder en veel plezier met de stats.

Idd! Lekker vrij geweest?

naar TG (kom op luitjes, we kakken een beetje in )

Valt wel mee denk ik. Heb thuis nog een hele boel WU's klaarstaan voor verzending. Maar na dinsdag heb ik er geen tijd meer voor gehad om ze te verzenden. Dus mijn 2 koetjes gaan gewoon braaf door... Denk alleen dat vanochtend/middag 1 koe even zonder gaat raken....

Zal kijken of ik morgen even tijd heb om wat terug te sturen naar Berkeley.

Ik ben helemaal de quote-van-de-dag vergeten

This morning we turned off the scheduling server on ptolemy and started it up on anakin. This basically worked right out of the box. Pretty quickly we determined the lower traffic rates were due to DNS rollout. Despite having the TTL (time to live) on the download name (boinc2.ssl.berkeley.edu) set to 5 minutes, it sometimes takes weeks to fully convince the world the change has been made. This is due to various types of DNS caching I still don't fully understand (why don't they all obey the TTL?). Stopping/restarting the BOINC client sometimes resolves this.

However, after an hour or so I decided to play nice and turn ptolemy back on, set in a way using apache to forward all lagging scheduling requests over to anakin with a "permanently moved" warning. I guess I should have done this from the get-go, but better late than never. Immediately this seemed to help, but only the uploads. Download traffic still remained under some rather low ceiling.

So I checked the two redundant download servers (bane and vader). Turns out bane wasn't serving any download requests. Was it even getting any? That part is a total mystery - nothing changed in any configurations pertaining to these servers. I double checked the DNS updates. No smoking guns there, either. Well, bane had weird dns/mounting/apache problems before that a quick reboot cleared up, so after rebooting it seemed to be "better" but not by much. Instead of 0 requests per second before reboot, it started serving 2 or 3 - vader is serving around 10. What's the deal, then? Perhaps this has to do with our "pound" load balancing utility recognizing bane was having trouble (strangely coincident but unrelated to the anakin switch) and has been favorite vader until bane got better. I filed this under "unrelated and currently harmless problem."

Anyway.. I then noticed (in between doing other tasks, hence the lag) the upload traffic was increasing way beyond expectations. I assumed everything was okay as all the apache logs were reporting no errors, but indeed the requests forwarded from ptolemy to anakin were failing. Why? Because the http headers were missing variables, including the all-imporant "Conent-Length." Why?!! This I have no idea, but apparently between apache (and/or the boinc client) redirected traffic results in different and less informative http headers. And so the schedulers on anakin were saying, "I don't know what you want - try again in 10 seconds." This got worse and worse as more clients wrapped up their currently workunits and tried to connect.

The solution to all that was to *not* do apache redirects (both 301 and 302 redirects had the same effect) but to use good ol' pound to simple shovel ptolemy's packets towards anakin. This helped all our DNS-lagging clients to finally connect again, but won't help to inform them that the scheduling server has indeed changed. Hopefully the clients will learn on their own in the coming days. We plan to turn off ptolemy outright early next week.

Nitpicker progress has been slowed by database programming issues. Informix has undocumented limits on user-defined lists in certain contexts. We may have to work around all that using something other than lists. Jeff's been banging on this and other similar programming hurdles for a while, hence the lack of recent info. Plus we have yet to sit down and discuss candidate scoring algorithms which will only happen if we can manage to get the four parties involved (Dan, Eric, Jeff, and me) in the same room at the same time without greater problems hanging over our heads. This hasn't happened in, well, months. At least glacial speeds are non-zero speeds.
