Why my last WUs were cancelled with no point?
If you don't need them, firts just write news on homepage to cancel them.
I waste many hours of computing for nothing :(

Most of the time Albert@Home will have no work to run at all, and when it has, the applications are experimental, might be unstable, unreliable and may even damage your computer. Validation might be unreliable and we may cancel workunits without prior notice. If you care about credit, this project is certainly not the right one for you.

They say most of your brain shuts down in cryo-sleep. All but the primitive side, the animal side. No wonder I'm still awake.

OK, but they might at least set the quorum at 1, like QMC@home and Test4Theory@home, also a Beta project.

Like it says on the home page "Don't expect ANYTHING to work here".

At least you only lost a few WUs worth of time. I've lost about 20 WUs (so far), and one user lost 700 in one go last time this happened. It goes with the territory.

It's not a project for the credit collector. Best to assume zero credit for everything and treat anything you get as a bonus :) Plenty of work at Einstein if you want a more reliable project.

Think about what that would do. Are we really trying to see just that a task can finish or do we want to be sure that all versions of the app on a range of platforms can get compatible answers?

Once the app runs reliably, increasing the quorum significantly would probably speed up the process by identifying incompatible answers more quickly. Take a look at this quorum. There were three successful completions but one was deemed to be wrong. And notice the three different platforms. More work for the Devs :-).

Cheers,
Gary.

OK, I understand this. I have 2 BRP3SSE units running, one in Albert@home and one in Einstein@home. Both are at 47% but the first took 22 hours, the second 15 hours. Why this difference?
