Note: At least in the short term, I am not planning to extend the report deadlines. The size of the database grows directly in proportion to these deadlines, so keeping the deadlines shorter reduces the strain on the server and allows more people to participate.
A single E@H workunit should take 7 or 8 hours on a modern machine, and perhaps 24-36 CPU hours on an old machine. Provided that the machine is available for BOINC at least 10% of the time, most machines should be able to complete the workunit by the deadline.

Yes -- in fact I made some modifications to the scheduler to do this. But then David Anderson (chief BOINC architect) persuaded me that what I had done was not a good idea. So I backed it out. I'll probably come back to it in the future.

During 3.5 days after creation, the WU goes to the first machine which has the right data file, that needs work. During the next 3.5 days, it also has some probability of being picked up by a machine that has NO data files. Finally, after 7 days, it goes to the first machine that requests work, which has a broadband (>100 kB/sec) network connection.

This is because we increased the memory requirements to 70 MB, and your machine has 64 MB. It has nothing to do with the deadlines!
Dont' the messages in the BOINC GUI tell you that no work is arriving because you don't have enough memory?
The next app version should use less memory, so in a little while this machine should again be able to run E@H.

I'd appreciate feedback on this. I decided to leave completed WU in the database for 7 days, to let our participants go back and examine them. Reducing this storage time would indeed help to keep the database 'lean and mean'. Would less than 7 days be OK? What do you propose?
Cheers,

After reading the comments,
)
After reading the comments, I'm still undecided about what to do. So in the short term I'm not going to do anything. In the longer term, the option of having a shorter time before completed WU are purged from the database, and a longer deadline, seems reasonable. I'll mull this over.
[Oh, in response to one question: no, after the WU is purged from the database, it is only available in our archives, not to other projects, statistics servers, etc.]
Cheers,
Bruce

The scheduler thinks that the jobs will take 28928 CPU seconds to complete. It also estimates that the code runs 58% of the time on your machine and thus will complete in 49,239 wallclock seconds. Hence since the machine requested 529,800 seconds of work, it got 8 WU. The next request, a minute later, got the same response because you have a two CPU machine.
Note that according to this: rsf 1.000000 the E@H scheduler believes that this machine has 100% of its BOINC resources devoted to E@H. If you are also using it for SETI@Home, then you need to reduce the resource share fraction, I think.

Martin,
Deutsch war ein Angebot an Dich, nicht eine Verpflichtung. Feel free to write English or German.
If you run two boinc clients, one for Seti and the other for Einstein@Home it becomes clear that they don't know of the resource share. However you don't need to run them this way. I'd suggest to o the following:
- Let Seti run until the current Result has been finished.
- Stop the client by typing ctrl-c in the terminal window
- Start it again with the option "-update_prefs" followed by the Seti URL, e.g.
./boinc_4.19_powerpc-apple-darwin -update_prefs http://setiweb.ssl.berkeley.edu/
to report the finished results. Stop the client again.
- cd to the Einstein directory and start the client with the option -attach_project
./boinc_4.19_powerpc-apple-darwin -attach_project
It will prompt you for an URL and a key. Enter your Seti account here.
You will get a client that you only need to start once and that properly honors the resource share settings.
(this will also work the other way 'round, attaching Einstein to the client currently ruunning Seti, but Seti WUs are faster)

It will work exactly like the windows client, the interface is different, but the functionality isn't. You will attach the same client to two projects.

Actually I'm also suffering from the inconveniant and user-unfriendly way the Mac client works right now. I'm one of the people who are trying to make this better behind the scenes, but it will still need some work.

You told that you have attached a windows client to two projects. Does it get confused with the files? Trust me, and simply follow the instructions.
In the FAQ there is listed a thread with some descriptions how to follow the percentage done of command line clients. When attached to two projects, the client_state.xml will have two fraction_done lines, one for each project.
I've never used it myself, but I'm sure that people here can advise you how to install DeepThought without using your work. It is a GUI for the boinc client for the Mac and should make things as easy for you as you know from Windows.
