hi guys.

i'm new here. want to help everywhere i can. but some strange thing occurs, please explain this:

statistic of one of my host:
http://boincstats.com/en/stats/-1/host/detail/254114457/projectList
intel xeon 3.0 GHz, 4 real cores, works on 8 threads 24 hours per day
3174 credits/day

statistic of some another host (not mine):
http://boincstats.com/en/stats/-1/host/detail/113094149/projectList
intel core 2 2.13 GHz, 2 real cores
568227 credits/day

where is magic? is credits calculation or performance issue?

thanks

The second host is running an AMD Radeon HD 7870/7950/7970/R9 280X series (Tahiti) GPU, you are only running CPUs.

GPUs output work much much faster than just plain CPUs do.
And with the hyper-inflated credit amount that Collatz gives out for work, it's easy to gain large amounts in a short time span.
If you put one or two good GPUs in your system, you'd be having the same credits in no time.

Projects are allowed by themselves how many credits they give out for work done there. There is a 'default' credit system in place, but a) it's broken and very difficult to work with when you do get it to work, and b) BOINC doesn't dictate that projects should use it or else. It's open source software so anyone is able to add their own credit system to their own project.

Most of the credits in your second example come from two projects - Collatz and Milkyway. Both of those projects make extensive use of GPUs - 'Graphical Processing Units', or high-powered video cards. They can do much more work than the CPU by itself, but they don't show up in the statistics kept by BOINCstats.

thanks. makes sense.
