Hi,

I just found out that "Average floating point operations per second" is calculated by RAC here which seems wrong to me cause the more a project grants the more Flops there are - which cant be realistic.

If I follow this calculation, my AMD X2 5200+ does 7 GigaFLOPS @ WCG - but @ Milkyway, it does 30 GigaFLOPS.

I just remember the news from January 31st, which said that according to BOINCStats more than 1 PetaFLOP has been calculated per second...

Well, what would be a more realisitic number then?

Cheers, Shai

Shai:

The problem isn't with the stats here, it starts with the projects:

A Cobblestone of computation is supposedly 0.86 trillion floating-point operations. . .

. . . BUT with optimized aps, different processors, different projects, different operating systems [esp. 64-bit] the reality bears only casual resemblance to the theory.

The programming gurus have a acronym for it: GIGO [Garbage In, Garbage Out]
