I believe it is a case of division by zero. :)

Indeed. Then the question is, did chalsall program the infinity, or did it appear on it's own? If the latter, that's awesome.

Indeed. But as RichD pointed out, for the particular ranges and bit-levels in question, one or more test was run but no factor was found. With additional samples, the values should converge on the theoretically expected value. That table is based entirely on samples we've seen -- it does not draw from the PrimeNet data set.

And to answer your follow up question, no, the infinity symbols had to be hand coded, or else Perl would have thrown a divide by zero exception.

They should, but they don't. The quantity is so small I don't think it's worth bothering.

Well there's 100+ assigned, and that's not insignificant as far as 'exponents been fully factored', where that's one possible interpretation of 'returned to PrimeNet'. And really, they were returned, because they're no longer assigned to "GPU Factoring".

I think that when something breaks it's usually the work of the trolls, usually the fish get blamed.

These GPU thingies are just amazing. We are averaging a GHz-day every 53 seconds. How insane is that?

firejuggler · 2011-12-15, 00:15

so, about 1272 GHz/day by 24H? this is scary

Ever heard of the "glass ceiling"?

Tinkle, tinkle, tinkle....

How can we be sure your percentages are only 6 digits?
