Technical News, and SETI@home daily stats for 02.11.2007.

[Rattledagger]

Feliz Dia de los Muertos (Nov 01 2007)

So the new load balancing regime on the schedulers has been working great. That's good news. On the other hand, our science database replica still isn't quite perfect yet. At least we're finding it to be resilient (i.e. we don't have to reload it from scratch every time it barfs). It got into a funny state yesterday, and had to be ungracefully killed. We rebooted the system to clean the pipes and then it recovered just fine. However, the reboot tickled a disk controller problem we've seen before where a tiny random subset of disks were invisible after reboot. Luckily the RAID is robust enough that this wasn't a big issue. We fixed this problem the way we did before: a full power cycle. The disk controller must be hanging on to some broken bits that only a complete power down can remove. In any case, we really need to invest in those networkable power strips at some point.

Smaller items: Various web site issues arose yesterday afternoon. A partial update of web code was in conflict with older parts. Dave cleaned that up this morning. Meanwhile Jeff and I are getting ever closer to fully automating the multibeam data pipeline, from Arecibo, to UCB, to the splitters, to our clients, and to/from our archives down at HPSS. We are hoping that someday soon we break through whatever bureaucratic dam(s) to get gigabit out of the lab (still currently stuck at a 100 Mbit ceiling for the whole lab, including our own private ISP strictly for SETI data downloads/uploads). By the way.. we believe we'll start collecting fresh data again at Arecibo before the end of the month.

And oh yeah.. I'm closer to making this page ready for prime time (doing regular daily plots, making selectable archives depicting other signal types from other 24 hour periods, maybe even animating them):

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:

 

[panhead49]

thanks!! RD

 

[petrusbroder]

Thanks for the stats, Rattledagger!
It looks good: some 171 K the day before yesterday, 167 K yesterday! wOOt!
Lets do some more crunching - and try to keep Team China and Team Starfire World BOINC behind us!

 

[Assimilator1]

And so Team Anandtech starts cranking it up

I'm switching to SETI tonight to factor in the ~1day delay on credits ,just waiting for a F@H WU to finish ,which will be soon.

Incidently ,it seems that F@H GPU & SETI don't play togther as well as F@H & DPAD ,SETI hogs all the CPU power! ,DPAD shares 1 core with F@H.
And since you can't pause 1 SETI client as far as I can tell ,I'll start SETI after F@H's done.



Are we ready to rumble?:evil:
