Is there any time frame for when more Window's WU's to be available than there is now ? I've suspended work call on most of my PC's for this Project because all I ever get anyway is the work committed to other platform's message & I get tired of seeing it fill up the Message box ...

My windows machine cannot get workunits for a long time too... What's wrong, Andre?

I did manage to snag a few WU's this morning on 1 PC but that was it over the last few days ...

I'm working on this right now. Apparently this is due to how boinc treats the infeasible_count of results in the shared memory and the people at World Community Grid had exactly the same problem. Here is their explanation:

------
The problem with the infeasible flag is that if a computer that is too weak comes in and requests work it sets everything to infeasible in the shared memory segment. This in turn means that the new computer that comes in looking for work sees that everything is infeasible and just grabs the first workunit they find. If you are using homogenous redundancy (AK: which is what we do) this means that instead of work that has already been designated to a particular os/processor being sent to that computer - any result will be sent to that computer. This causes more workunits to be quickly assigned to a particular HR category and although you eventually work through the shared memory segment results that are marked infeasible, you still have to deal with the issue of most or all of your workunits in the shared memory segment being marked with a HR. This usually results in one or more types of computers not being able to receive work and the 'work is available for other platforms' message being sent out.
------

They also have supplied us with a possible fix for this that I will be implementing and testing today. If it works, this problem should mostly go away.

OK. Fix implemented and increased shared memory segment from 500 to 1000. This should get a lot of work to a lot of machines (incl. windows). Let me know if you still see the 'no work' message a lot (occasionally is possible).

That did the trick big time Andre, I woke from my nap & had to shut of WU Requests again for fear of getting to many & not being able to finish them in time before the Dead Line, I have enough now on my Computers assigned to this Project to run about 4 days straight ... :))))

There is still something I don't quite understand in boinc: when a client asks for let's say 18000 secs of work, the server sometimes assigns much more work than that (in some cases 4 days like you). This doesn't seem right to me, but I have to investigate further.

It could be because I had my Preferences set to 10 days Andre in an attempt to get work & while I was sleeping you made the change so I got almost to much. I'll back my Preferences off to 1 day now like I normally run it so I shouldn't get as many once I run these down & the Client asks for more work ... Also the PC's I have attached here are Conroe's & they do ask for a lot of work anyway ...
