@7.62: Ok, I got the Tesla thing now ^^.
I can't because I'm just renting them for a few months in a hosting env.

If I spent a lot of money for Crunching-Equipment to crunch for science: Can I set it off against tax liability?

@Alexpc1:
Hosting, gotcha! (Thinking extreme workstation) Still impressive output for a hex core with HT. 5-6K per CP

Computing for "science" on an AMD GPU lacking double-precision. Do any projects exist that involve this "science?" No maths.

@7.62 science without math "omg, it's full of stars"

@scareg:
Wasn't too sure about running BOINC 7.x just for POEM. That's why I figure I never got GPU tasks.

@7.62: I'd still like to know if a 24 thread X5680@3.33GHz is better for crunching than a 4 thread Core2Quad@2.66Ghz.

@7.62: Because stats say the Core2Quad is about 3 times better, so I'd like to understand why/what's the main diff ^^

@NATE1: PrimeGrid doesn't need Double Precision, Moo! runs perfectly on my Llano system, as does Collatz

@Dirk Broer: He said he didn't want to run a math-only project and even explicitely cited PrimeGrid as counter-example

PrimeGrid requires OpenCL support, but does not need Double Precision

In fact, only MilkyWay does need Double Precision at the moment.

nVidia GTX 680 is good in Single Precision, runs at a reasonable wattage

But it is no better at Double Precision than a HD 4830

You'd need 10 GTX 680s to equal the power of one HD 6990, Double Precision-wise
