I'm late to the party, and the survey was closed! The topic "Embracing Diversity: The Design of Citizen Science as an Online Inclusive Environment" was still visible however and sounds very interesting, hope they got plenty of responses!
2) Forums : General Topics : 450 Credits for 15.5 hours? (Message 21627)

It's hard to compare apples and pears, as BOINC tries its best to do with the credit system. I've just started with C@H and my laptop which is my trial machine for projects completes a camb_boinc2docker job in about 9 minutes with all four virtual cores (i7-7500U). That's ~30 cpu minutes for ~30 credits or 60 credits per hour. Double what you describe but I don't know what hardware you're running on nor which application it was.

Anyway - try focusing on what's important. What those 15.5 CPU hours does to progress our understanding of the cosmos! If it's 450 or 45000 "credits" is of less relevance.:) (But I know - big integers ARE fun, no matter what people tell us!)

Many project applications fail once in a while. Understanding why one specific task fails requires intimate knowledge of that application. If the application developer of camb_legacy is nearby I'm sure he or she would reply.

Looking at this work unit another computer completed the task and was validated as correct. Usually when that is the case I'd point at a computer fault (memory error for example) or a compiler error (you're running on windows, the other computer that finished the work unit ran gnu/linux).

Quitting a project over a single task is a bit drastic in my world but you're of course free to allocate your resources wherever you want to!

EDIT: spelling.

I do not have the answer, but it was an Interesting article! From my understanding of C@H the data we produce could help (and maybe already has helped) with answering questions as these but it would be interesting to hear from someone more knowledgeable in the field.
