BOINC pisses me off. I added a new project, and only added Default and Work to the new project, because those were the only machines I was putting over there.
Damn it if BOINC didn't force my Home and School to Default since I didn't make them over on the new project, so my machines went crazy downloading a ton of extra work, using processors I had idle, etc.
I know how to fix this next time, but it's rare that I add a project. I need create the project on the website. Update an old project on all 4 Computing Preferences (since these update with the last projected that made the change) and the add computers to the new project.
STUPID. I only added 2 systems to the new project on Default and Work, but yet Home and School got totally messed up because the new project had them set as default.
I wish you could set a project at the PRIMARY project and all projects, even new ones follow those settings.
I also need more than 4 preferences but that's besides the point.
I just trashed over 200 WUs because it downloaded days worth when it was only set to .25 days. Why did it download like 10 or more days worth?!?! Ugh.
[edit]Edited for correctness of trashed units from about 50 to over 200 _________________ Watch the movie about me The 4-1-4s: The Original Teenage Hackers (It is only about 12 minutes long.)

By contrast, F@H allows only one WU to be downloaded at a time (per folding 'slot').
When an active WU reaches >= 99% complete, another WU is downloaded (or queued for that slot).
I don't understand why BOINC is designed to have its donors pre-load a bunch of WUs (kinda like "batch-mode").
What happens to those unprocessed (or completed but unsent) WUs in case a donor has an unfortunate, significant crash (major hardware malfunction, natural disaster, etc)?
I can see a small-ish benefit to that approach, however, in that your system doesn't need to have consistent, on-demand online connectivity in order to continue crunching despite intermittent comm errors.
But the reality is that most people now have broadband, high-speed WiFi, or even DSL connectivity - which, in most cases, tends to be much more reliable and robust than dial-up modem access.
The downside to this approach, is that it allows for WU hoarding.
I have seen quite a number of ping-pongs about "plenty of work" notices, shortly followed by "lack of work" notices for various projects.
Could this be symptomatic of hoarding?
And maybe that is the prevailing strategy - an early-bird-gets-the-worm attitude.
That reminds me of a coarse but clever table prayer: "Father, Son, and Holy Ghost; he who's quickest gets the most!"
I'm not trying to be critical of BOINC - I am merely curious.
I am just asking if anyone can explain the rationale or benefit(s) behind this WU batch-queuing approach (vs a one-at-a-time, serialized approach).
