How could I set up BOINC/SETIatHome to download only one work-unit a time, and that no new work-unit should be fetched before the completed unit is uploaded successfully?

I think...

Goto Computing Preferences in you're account and change - Maintain enough work for xx days, to 1 day, thats what someone once told me.

might be wrong though...
otherwise i have no idea.

I would recommend something smaller such as 0.01 days.

Even if BOINC is only downloading one task at a time, that happens shortly before the previous one finishes—assuming work is available. The only way to prevent that AFAICT is to set the project to No New Tasks.

In an ideal world, every time the science application needs a new work unit, BOINC would have exactly one ready.

To do that, it needs to lead the next work unit slightly.

So, I'd set the connect interval to something like 0.01, and the extra days to 0, and that should download a new WU a few minutes before it runs out.

If work is available, of course.

I have mine set to 10 days, but it still downloads 1 WU at a time, but im fine with that.

BOINC calculates how many seconds of work to request to the server based on the work buffer settings, project allocations, and stats tracking the percentage of time that BOINC is crunching daily. If you're only getting 1 WU for a 10 day cache, then something is telling BOINC that it will only manage to finish that much in that period of time.

If it doesn't seem correct, it could be for a number of reasons. I would check for a high RDCF (indicated by a est. time to completion that is way higher than it should be) or the computer on/BOINC running percentage.

I dont know, but my est completion of a WU when it starts is about 24hrs, but it finishes at 6hrs, i dont know why, is this ok or is something wrong?

You are running a somewhat older version of BOINC, and the current science application is 5.27, while you're running 5.17.

I'd update to the latest BOINC, get rid of your app_info.xml file temporarily, and see if that helps.

If BOINC goes a long time without running, it will think it's can't do much work. As each WU is finished and uploaded, it should increase how much work it gets.

Set No New Tasks, let any WU you have finish, upload, and report. Then, reset the project. That should help.

It will update automatically if you "reset" then "update" the project.

To get the equivalent new version of the 2.2B build you now have, go to Crunch3r's site and download the "2.4V Windows x32 SSE2 Intel+GFX" version. Unzip it and read the "instructions.txt" file it contains.
