[ANN][RIC] Riecoin: constellations POW *CPU* HARD FORK successful, world record

Congratulations, I see that you've released your YPOOL miner and I believe that the RIC network difficulty will be at its highest this week.

Last weekend, I fully implemented my miner using x86-64 assembly code in order to have a fair comparison with my GPU implementation. On the same hardware, with 20 Intel E5-2697 v2 CPUs total, I can now solve 24-32 blocks per day (@1300-bit difficulty) when taking the orphaned blocks into account. I currently do not have any server hardware that can support the AVX2 instructions which would have resulted in a 30 percent increase in performance.

Congratulations again - I will be back to this hobby late April or early May.

Sorry for the typos, I am on my smart phone as usual.

I did - privately for now, and I'll open source it in a few weeks - and with the help of a brave soul on ypool, diff has reached a new peak. 1368 and probably rising. I don't have a great comparison with the 2697, but it sounds like you've still got a 20-25% edge on my miner. I still haven't -- and don't want to -- touch the gmp internals, but it's getting closer to that point. Currently sieving out the first 200m-1b primes (depending on memory), and it's diminishing returns.

So it is time for me too stop mining Rie with my 4 puny cpu's now?

No - diff should drop again. This was a bit of an accident - it sounds like someone forgot to tear down some aws instances. Amazon made a lot of money. The miner, not so much. *wince*

I'm going to start trying to clean up the horribly ugly hacks I did when trying to make my miner faster in a hurry and put them into an open source version. I don't want to start my own, because I've proved incompetent about supporting windows and things like that.

Is there a preferred miner into which to do it? Gatra, I know you're working on stratum support. Which miner would be right to work on in order to be compatible with the stratum pools that will hopefully be showing up soon?

Let S be the sha256 of the first part of the block header (the nonce is not needed).

In binary, let basep be an 1 concatenated with eight 0's, concatenated with S, concatenated with as many 0's as needed to reach the required difficulty. Let Z be that quantity of 0's.

Find X such that basep + X is the first prime of a prime constellation of size n, where n is hardcoded at 6. The value of X should not be larger than 2^Z
