Technical News, and SETI@home daily stats for 24.05.2007.

Lookin' Up (May 23 2007)

Some good news in general. With some extreme debugging by Jeff and the rare manual-reading by me we got fastCGI working for both the scheduler CGI and the file upload handler under linux/apache2. On hindsight not terribly difficult but it wasn't very easy to track down the issues given fastCGI's penchant for overloading FILE streams and whatnot. The servers were going up and down this afternoon as we were employing the new executables and working out the configuration kinks.

The results were vast and immediate, which then caused us to quickly hit our next (and possibly final) bottleneck: the rate at which we can create new work. As it stands now the splitters (which create the work) can only run on Solaris machines, three of which we recently retired (koloth, kryten, and galileo). We have every possible Solaris box we have working on this now including three not-so-hefty desktop systems (milkyway, glenn, and kang). We could put some effort into making a linux version of splitter, but I don't think we'll bother for several reasons including: 1. we are sending out workunits faster than we get raw data from the telescope (we always claimed that this would be our "ceiling" and wouldn't put any effort into making work beyond this rate if we don't have the resources), and 2. we are quite close to running out of classic work that is of any scientific use. Any programming effort should pour into the new multibeam splitter, and I sure hope we finish that real soon.

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 RD

Are we still not getting enough WUs through? ,our output seems low.

 

[BlackMountainCow]

Thx RD!

I really like the SETI news; the devs seem to have a lot of self-irony for their job :evil:

Due to a bug in server-code, anyone using optimized application, app_info.xml, didnt get any work at all, but instead has only been generating "ghost"-wu.

This bug was finally fixed by installation of new scheduling-server-code, as mentioned in Technical News for 23. May.

So, only now should finally everyone have started getting new work. Also, due to the bug with "ghost"-wu, many wu will need to wait until the deadline before they'll be re-issued, and enough results to validate can be sent-out for these wu's...

Thanks fo rthe info and stats, Rattledagger!
It still takes a few hours before some WUs are uploaded ("HTML-error in Server") but after some time it works OK.
