A "Work unit" (WU) is just a

A "Work unit" (WU) is just a "slice" of work that a project finds suitable to be crunched by a single machine. The "size" of this, i.e. the number of (usually floating-point) operations it requires, and thus the time it takes on a specific machine, may differ a lot between two projects, and even between two Workunits of the same project.

WUs of SETI and Predictor I found to be rather short (1-2h). Ours have been calculated to be roughly done one in a day on a modern machine that uses 50% of its time for processing Einstein@Home. CPDN has Workunits that take hundrets of hours, so actually months, to process.

I read about people needing so many hours per "Work Unit". I recall the "Work Unit" from my previous involvement with SETI. Where do I find the info about "Work Unit" involving Einstein?

If you changed from the terminal to BOINC Manager, all you need to do now is open the manager window to see what is happening with the work. You should have a BOINC icon in your menubar. Click on that and you will see "Open BOINC Manager". (If it is greyed out, just release and try again and it will work. It always seems to be greyed out after a restart).

The projects tab shows you what projects you are connected to. The work tab shows the work units in queue and their current progress. The Messages tab is like the terminal window, showing any ongoing messages from the client. (most of which can be ignored).

Hope that helps.

Well I upgraded to the latest

Well I upgraded to the latest .05 app and so far so good. I have resumed Predictor and work has downloaded, but it looks like it won't start switching between projects until I complete some of the Einstein work due to deadlines. Should know by the end of the weekend, if the issue of not switching smoothly between projects has been fixed.

Shaktai or Bernd,

Perhaps one of you could answer my question. Is this a Boinc 4.44 compatible version or should I continue to use the Boinc 4.43?

Thanks in advance!

MacStef. It is a beta client. I can't really say for sure. The whole idea is to try it and see. If your not willing try and provide feedback on your results, it is best to stay away from beta tests and beta clients. I still don't know why you had so many client errors. You are so far the only person I know of that had that many. You need to provide detail on your computer setup and other software running. If you want a stable client, stick with the stock ones. The whole purpose of this thread and the equivelent Windows thread is to test the beta apps, provide detailed information and help to find the bugs. Beta, means the app still isn't stable. Once it is, then it will become the standar app for all users.

Bernd, Looks like the Beta

Bernd,

Looks like the Beta App is still not playing nice with other projects. It doesn't show in BOINC Manager, but it does show in Activity Monitor. Below is a link to some screenshots that show what is happening. Scroll to the bottom of the page to read the captions. As they say, a picture is worth a thousand words.

Tomorrow I'll switch back over to the standard "unoptimized" BOINC client and let you know if there is a difference.

MacStef: Sorry about the

MacStef:

Sorry about the delay in answering - I was flying from Los Angeles to Washington, DC, today. So far, the Einstein 0.05 is running fine with BOINC 4.44 SuperBench from Team MacNN. I just reset my preferences an hour ago or so to give SETI and Einstein equal time (Einstein had been set 20:1 advantage. I should know by tomorrow sometime if the pausing problem is solved for me... Einstein finished a WU about an hour ago, but I didn't have my Airport card turned on, so it couldn't download another WU. Instead, it started running CPDN again. In another hour and a half, I should see it switch from CPDN to SETI... I've got OS X 10.3.9 running on a PowerBook G4 1 GHz, with BOINC as CLI in Terminal.

I forgot to mention...

I forgot to mention... Result 6687975 is the WU that was running at the time I installed 0.05. After installation, this WU resumed running, finished, and uploaded. It appears to me it was successful. Result 6727511 is the one that just uploaded an hour or so ago, and it hasn't shown up yet on my results page.

Okay, backed off to the

Okay, backed off to the unoptimized BOINC 4.43 client. Same problem, Einstein shows in BOINC Manager as being paused, but in the background the Einstein app is still running with the Predictor app.

By itself, the beta is working great. The problem is the app doesn't stop running, when another project starts, and einstein should be paused. I added a third screenshot showing the unoptimized 4.43 client. Looks like the problem is with the Einstein app that it just doesn't quit cleanly, when another project starts.

Thanks, C! Am I

Thanks, C! Am I understanding that you upgraded to Einstein .05 while you still had Einstein .02 WUs crunching and they didn't get fracked?!

Shaktai, I think I know what a Beta version is. I currently Beta test for Sony as well as a few other smaller software developers. I was only asking what other people were running because of all the problems I had with the last Beta Version.

As for what cpu I am running and other software, nobody has ever requested any info. from me. I am more then happy to help in any way I can. I have noticed that most of my problems went away after Dumping the MacNN Boinc 4.44 and going back to the Boinc 4.43. after doing that, the only problem I have seen is the same as all of you. The pausing bug.

Anyway, I appreciate the help and hope I can contribute in some small way.

MacStef
