One Question about the certificate. Is that Quintillion short oder long scale? ^^

Short scale, so:
10^6 Million
10^9 Billion
10^12 Trillion
10^15 Quadrillion
10^18 Quintillion

Not long scale, since Quintillion would be 10^30 on the long scale. That would not be conform BOINC credit:
http://boinc.berkeley.edu/wiki/Computation_credit
1 Cobblestone = 1/200 day of CPU time on a reference computer that does 1,000 MFLOPS = 1000 MFLOPS *60*60*24/200 = 432000 MFLOPS or 432 billion FLOPS

In my case: 748,494 Cobblestones of computation (646.70 quadrillion floating-point operations) to GPUGRID.
748,494 x 432 billion FLOPS = 323,349,408 billion FLOPS = 323,349 trillion FLOPS = 323 quadrillion FLOPS
Possibly GPUGRID doubles that amount due to the use of GPUs. But more importantly it is in the order of magnitude. So I think it is save to assume that they use the short scale.
