SETI@Home "struck" wu-problem hopefully fixed, and other news...

[Rattledagger]

Since the release of Seti_Enhanced, there's been many -9 result_overflow-wu that has either continued to crunch but %done has been stuck, given a runtime-error, and displaying a message "runtime-error, click ok". A very limited number has also crunched for many hours, before finally giving -9 result_overflow, but only 0.1 Cobblestones claimed credit. Hopefully all these problems have now been fixed:

Thanks to some clues from Josef Segur and Tetsuji Rai, I've located the cause of the "overflow results that hang" problem. It appears that it wasn't an application issue at all, but a problem with the splitter that resulted in thresholds that were set too low in such a way that the triplet finder attempted to do an infinite amount of work.

This is also the cause of some long running workunits asking for too little credit.

The problem has been fixed and I've started the new splitters. Once these results get cleared the problem should go away. I'm working on a script to fix the problem.

You can identify workunits made by the new splitter because they will have values in the <keyuniq> header field between -12288 and -13312. If you have problems with the new workunits, let me know.

If the beginnings of their names appear in this list then you should probably delete or abort them.

AFAIK these wu on the list has been cancelled, meaning will not be re-issued, but if you've already downloaded any of these they'll still try to run as normal...

Now, after re-starting the splitters there seems a bunch of bad wu was split, but the problem with these is they're missing the header, and will therefore immediately error-out when started to crunch. So, appart for someone with non-permanent connection, these shouldn't really be a big problem.


Anyway, in other news, some users from various teams is having a 1-week "strike", most common method to "strike" apparently to fill-up the cache and disable network for a week... :roll:
Also, the SETI@Home-forums has still not cooled-down, so appart for reading, wouldn't recommend anyone to try post anything there for now...

BTW, was thinking about having a 1-week "anti-strike" and run only SETI@Home, but decided against it, since CPDN is slow enough to crunch. 😛


In more positive and exciting news:

Dan and Jeff are at Arecibo setting up the new data recorder. There's also a box of new data in Arecibo that we're waiting on....(02.06.2006)

The new data that's waiting at Arecibo is on DLT IV tapes. The recorder that Dan and Jeff are installing uses an newer DLT (350GB?) format.

On a related note, SERENDIP IV and the original SETI@home data recorder were disconnected today. Everyone please raise your glass in a toast to their memory.

We've got a new graduate student (Josh von Korff) working on Astropulse. He found a number of bugs in the existing app, some of them serious in terms of the science. He's working on a new build. Most of the code is based upon the old version you were beta testing.

I can't give you a good ETA for the new version. Josh is at Arecibo right now helping Jeff and Dan with the data recorder and he needs my help for some problems he's having.

And now, last but not least, the stats: :beer:

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...

[BlackMountainCow]

Many thanks for the read RD! Made keeping up to date much easier for me! :thumbsup:

 

[Assimilator1]

Thanks for the info RD ,very handy🙂

I like the anti-strike idea 😉

I wonder if someone will pop in here & ask us to strike?😛
