Hello,
Sorry if my english is not as good as yours. I do my best to read the forum and trying to understand what's going on.
I am not able to download AP wu during the 3-4 last weeks.
I checked the serveur status and see the AP split is "done". I checked the technical staff forum. I checked my preferencesand everything is OK.

Can somebody explain me what is going on.
My BM is 6.6.38.

Thanks
Lionel, from France.

If you have set "If no work for selected applications is available, accept work from other applications" to "yes", you have done all you can.

There's just a 33 to 1 chance to get an AstroPulse task. So, you've just had tough luck, I think.

Gruß,
Gundolf
[edit]As Matt said in the technical news, there's difficulties in getting software blanked AP tasks. And the current "tapes" are (done).[/edit]

You need to ask for work that isn't available to get that switch to work,
and also you Don't want ask for work that Is available!,

so select SETI@home Enhanced to 'No' as well, leaving Astropulse and Astropulse_v5 to 'Yes'.

Thanks a lot. I'll try your receipe.

Server is like this for several days. No AP available for now.

Okay, so where are we... Over the weekend the raw data queue shrunk down pretty far, but don't fear. Astropulse ran out of work to do, and multibeam has maybe another day or two, tops. Meanwhile I'm working behind the scenes actually splitting a bunch of software-radar-blanked data from 2006. This is actually going out now to people, but just doesn't show up on the server status pages. I'd have to do some minor hacking to get these files to show up on that page, but that'll be moot fairly soon as all data will be software-radar-blanked and I'll just point the script to look in the new data directory (as opposed to having it look through two directories and figure out the combined status of everything).

Anyway, there's that. We might run a little dry over the next few days as I'm still scraping together disk/memory resources to get these old files pulled up from the archives, analysed, and embedded with the new blanking signal. Only then can these files be split into workunits. I'm working on it.

Meanwhile, we're still having sporadic problems with informix locking up on us. It's getting to be really frustrating, as you don't really notice anything is wrong until the workunit queue runs dry or something like that. The idea of migrating to another database engine is on the table again. Also, bruno was having some nagging mount issues so I just now rebooted it. You may have noticed the whole project disappearing for a half hour there. That was me.

Rumor has it Jeff is back in town. He was away for several weeks hiking in the Himalayas. I imagine he has jet lag and other kinds of recovery to deal with, and he'll appear maybe later this week.

So expect work even if the splitters say disabled.

As many of you already know, Tuesday is the regular outage day where we dry clean the mysql database and pack it down tight. We're recovering from it now. Today I also did some testing of the newly employed solid state RAID 1 on mork (the master mysql server). It seemed fine, so this device now holds the mysql/innodb logical logs, thus resulting in far less competing writes with the data RAID 10 (where the logs used to be kept). Will this help much? I dunno. A non-zero amount at least.

I'm still assembling the new data pipeline. Got a few files in the queue now for multibeam analysis, but I can't seem to get a new astropulse splitter to compile. I need to recompile so that it reads the software radar blanking bit instead of the hardware one, but I'm hitting some library/include issues. Sigh. One of those problem you know you'll get working eventually but right now the path isn't exactly clear, and everything will be annoying until you finally get a successful "make."

Expect no new Astropulse work right away, a few hours?, days?, a week?

Jeff is back in town and back in action here at the lab. He's now working on the NTPCkr/RFI stuff (which has been languishing due to lack of effort and the science database throughput woes which I've been alluding to lately).

As predicted, I did finally get the astropulse version of the splitter to compile (just some library/linking bugs that had to be hunted down and exterminated). So astropulse workunits using the software radar blanking system are going out! Meanwhile, I hit some more management snags with the multibeam stuff - I'm trying to blank/split really old files which we recorded before we had all the kinks worked out. Long story short, some files I spent a lot of time (days) pulling up from our archives and doing the first stages of radar analysis are unsplittable. Darn. I was hoping to just get beyond the dearth of data in the nick of time, but it looks like I got to pull more files up from the archives, and we'll run a bit dry before they are splittable.

Today is a particularly windy day, which means it's fairly clear. Here's a picture taken from my iPhone looking out from the lab patio onto the Bay. That the Lawrence Hall of science directly below me, then downtown Berkeley, then the Bay itself, then San Francisco, the Golden Gate Bridge, and the Marin Headlands in the distance. The detail isn't so great, so you can't see that the Bay Bridge is completely devoid of cars right now (it's shut down due to technically difficulties), which is quite rare and quite odd.

3 hours later, astropulse wu's are going out, maybe in a limited number through.

Well.. wait and crunch...
Thanks for your help.
