Re: Vertcoin - 1 | ASIC - 0 | Lyra2RE | Decentralised | GPU Mineable

What do you think, are there private kernels with improved rates?
If yes, how much faster do you think they are?

As for the botnets, all GPU coins are susceptible to botnet mining, however the good coins give GPUs enough advantage over CPUs so that the combined mining power of all GPUs is not less than or equal to one single botnet.

Now look what we have here, just a couple of posts above.

I don't know of any faster private kernel, even though I've heard of them at times.
There are arguments for making gpu mining slower compared to cpu. For example making mining unprofitable for gpu farms.
Then there is that old romantic idea of everybody mining on their laptop, too :-)

Well the algo is being modified at the moment so that it favours GPUs over CPUs. Most likely the easiest way to do this would be to swap out one of the X* algos for another one that is better with GPUs

Almost all the kernel time is spent on the lyra part (which is essentially Blake on a bigger internal structure). It is slow because it doesn't fit in the registers nor in local ram; and the access is random, not sequential.
So if you want to make it GPU friendly, the only way is removing the "lyra" from "lyra2re". What remains is something similar to a subset of x11.
