Title: Re: The network just hit 40 PetaFLOPS! Post by: jarly on May 22, 2011, 11:01:59 PM Why are you measuring hashes/s in FLOPS?
Title: Re: The network just hit 40 PetaFLOPS! Post by: Convery on May 22, 2011, 11:12:33 PM Why are you measuring hashes/s in FLOPS? What else would you measure it in?Title: Re: The network just hit 40 PetaFLOPS! Post by: Quantumplation on May 22, 2011, 11:17:12 PM What else would you measure it in? ... Hashes per second? 1 FLOP is Float Operation, and there are many float operations per hash, so it's kind of a misleading unit of measurement when talking about network performance.

I assume it's because bitcoinwatch (http://bitcoinwatch.com/) shows TeraFLOP/s (as well as Gigahashs/s).Title: Re: The network just hit 40 PetaFLOPS!

Post by: 1bitc0inplz on May 23, 2011, 01:09:05 AM Why are you measuring hashes/s in FLOPS? because hashes/sec is meaning outside of Bitcoin. If we want to know how big the network is versus a super computer, what else would you measure it in? Title: Re: The network just hit 40 PetaFLOPS!

If we want to know how big the network is versus a super computer, what else would you measure it in? Integer Operations and Floating Point Operations are not comparable. Title: Re: The network just hit 40 PetaFLOPS! Post by: 1bitc0inplz on May 23, 2011, 01:20:08 AM Integer Operations and Floating Point Operations are not comparable. Of course... but then the whole hash/sec on Bitcoin Watch is an estimate anyway... So, when you get down to it, all these numbers are meaningless. However, knowing a rough ballpark of a FLOPs rate *is* interesting, because it does help you think in scale of the TOP 500. Title: Re: The network just hit 40 PetaFLOPS!

So, when you get down to it, all these numbers are meaningless. However, knowing a rough ballpark of a FLOPs rate *is* interesting, because it does help you think in scale of the TOP 500. But you can't actually assume any kind of estimate of how many FLOPs our network is. If I can do 2 Integer operations in one clock but only Floating Point operation per clock, you can't just say my 8 million integer operations per second are the equivalent of 8MFLOPS. Some hardware can even do 4 Integer operations in the same time it takes to do one single Floating Point operation. Edit: For hashing, the proper network computational power unit is MIPS instead of FLOPS. Title: Re: The network just hit 40 PetaFLOPS! Post by: ArtForz on May 23, 2011, 01:35:10 AM I get about half that assuming vast majority of hashrate is ATI 5xxx GPUs.
3Thps = about 8300 5870s = about 22.5PFLOPS peak single precision, 4.5PFLOPS peak double precision. Title: Re: The network just hit 40 PetaFLOPS!
