Well I suspect that somebody has a GPU miner active . one user has 40 MH/s on suprnova . Which to be honest 16 core = 650 kh/sec so lets see it needs around 80 cpu's with 16 cores. Makes sense ? Neah ... I am 80% sure that it's using GPU...

Ok fine with Xeon Phi would make it around 1.2 MH'ses so still it needs 40 of them .

I am using 2xXeon E5-2670 = 16 cores and gets me 650 kh/sec. So I guess Xeon Phi after some quick google research could do double .

I got it somebody working @ CERN | Accelerating science is throwing all the hashrate Cheesy

. The fact is with a C++ and CUDA or OpenCL coding knowledge could easily overwite the code from let's say spreadcoin ccminer witch is based on X11 and cpuminer similar to this coin. But those two miners were obviously so excited that they brag about rewriting the miner and now they call themselfs a "liars". Lesson learned, next time if u have an advantage be quitet, don't brag about it and enjoy it while it lasts Wink

For sure they can be easly rewrited . And kept somehow secret by why didnt use private pools ? Oh I forgot bragging . Meh I knew it will last a little....well few more days and the show it's over. A mega dump will follow for sure. And when people wonder who is dumping 1BTC of Ziftr per day you can look into pools it's easy to guess.

For what it's worth, we're aware of the miners with such large amounts of hashing power on the pools. It's likely that they're using GPUs, but we aren't fully convinced of that yet. We saw some users (who we know were just using CPUs) throw 140 MH/s at the network for a short time period last week. I also know my Intel i5 4670k (which is over a year old at this point) can get about 400kH/s. It's not out of line to think that there are users with 100 of those under their control. For example an IT guy at any local community college (where network security would be lax) with CAD and other engineering programs can probably muster that.

What it really comes down to for us is a balance of the total hashrate of the network and its distribution. There are ALWAYS going to be "whales" on a network. Now it's because they either have their own custom mining software or unrestricted access to many CPUs. When we "open the gates" it will be those with large GPU farms or cheap electricity. We don't like that there is a single user with so much power, but other than that the network is fairly well distributed and CPU mining is still very viable. We're already getting many new people into crypto (more than we expected at this point), which is good for all coins. That will go away when the coin becomes GPU only.

~500 MH/s network from CPU's only???
Come on!
