Technical news, and SETI@home daily stats for 27.04.2007.

Jeff is still fighting to compile a new splitter. Several roadblocks appeared when converting the old but working solaris code to linux (endian issues, for one). Meanwhile I was able to squeeze out a few more drops yesterday from our current set of solaris splitters. I niced them way down (giving them CPU priority), and even retrofitted kang to make it able to run a splitter as well. Kang is a rather useless (due to lack of memory/CPU) Sun Netra that we keep kickin' around for no good reason, really, except with some effort I was able to tease out a few cycles. All these efforts combined allowed us to finally get a work queue growing again, but just barely. We'll see if we stay above water over the weekend.

I appreciate people wondering what the heck "kang" was, being as it was never made public before. Honestly, it's fun to hide some of the facts at first to see what kind of speculation takes place first. And yes, there used to be a "kodos" but it died long ago.

A lot of my time today was spent putting some effort to tying users to the workunits they analyzed in the science database - a problem we've been putting off for too long. Seems simple but it isn't - one major obstacle being the BOINC backend having no clue about where the scientific results end up after assimilation. It doesn't have to know and it doesn't want to know. Likewise there is no user information in the science database because, well, there's no scientific reason for it. Anyway, it's up to the specific project to decide how they want to handle user acknowledgement as the result products are so varied. Another obstacle is that while this is a rather simple database, it is fully historic, meaning it's going to be big and requiring constant updates. Do we have the resources for such a thing?

So Jeff, Eric, and I decided on a third database which will be accessible by SETI@home web servers with ease and will be inserted with values during that brief moment during validation when one single process happens to have a user id and science database workunit id at hand at the same time. There's also a huge, growing stack of db_purge flat file archives (in XML format) on a RAID system which currently is the *only* copy of user-to-workunit information. I just wrote a script to parse those and plop them into the new database. The validator part is tricky - it requires I ramp myself up on validator code which will be a painful but ultimately good exercise. All told, when this is done there will be a button on your user page which will give you historic information about BOINC work you have processed for us. Maybe some fun graphics, too. One step at a time, though..

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

 

[Assimilator1]

when this is done there will be a button on your user page which will give you historic information about BOINC work you have processed for us

That sounds cool ,thx RD

 

[BlackMountainCow]

Yes, that sounds pretty cool!
