Re: rieMiner - Solo + pooled Riecoin mining

I see, I was always using a PN of 40 and got really awful results with that, as there is an insane CPU Underuse. Ah, yes I see that too. The problem is simply that there aren't enough candidates left after sieving to keep the prime testing threads busy, which is the same problem I hit when going fo...

Re: rieMiner - Solo + pooled Riecoin mining

Why do you say mining directly with a (0, 2, 6, 8, 12, 18, 20) configuration is very inefficient? The sieving for non 6-tuples is very slightly worse because it doesn't use the AVX code, but the difference is very small. I get what I believe to be reasonable results mining for a 7-tuple of difficult...

Re: rieMiner - Solo + pooled Riecoin mining

Up to 10000 RIC bounty for anyone that writes elegant code for a fourth mode (with Solo/Pool/Benchmark) that can be used to beat new records for different tuple lengths and makes rieMiner a reference software for prime constellation finding. Read this issue . Other issues were also open if anyone i...

Re: Mining on testnet

Cool, I'll leave it running for the moment then.

Mining on testnet

I've got the light version of rieMiner up and running on a Raspberry Pi and have been successfully mining blocks on testnet. Would it be preferable for me to leave mining on testnet running (ensuring difficulty stays near the minimum), or is it better to keep the testnet blockchain short and just mi...

Re: rieMiner - Solo + pooled Riecoin mining

There is something weird with 32 bits builds though... The performance is much worse, like 4x slower, even on a same Windows computer (that can run both), not sure why. I do not really care as not much people will mine with 32 bits computers, but still. I was unable to find the issue, even replacin...

Re: rieMiner - Solo + pooled Riecoin mining

Rockhawk, how did you find the 128 MiB + 650 MiB*SieveWorkers terms for the memory estimation? It seems to work good enough for big Sieves, but the estimation is imprecise for very low Prime Table Limits as it estimates ~800 MiB, while I am able to run rieMiner (from the Light Branch) without swapp...

Re: rieMiner - Solo + pooled Riecoin mining

I was just curious and ran the Benchmark without the precomputed data nor AVX, and surprisingly, there was no noticeable performance loss at all for the 2700X (after 100000 2-tuples)! In another hand, the lack of AVX did impact the performance in the 6700K, and the precomputed data too (but the cha...

Re: rieMiner - Solo + pooled Riecoin mining

Awesome. I think we can both be pretty happy with where we've got to over the last couple of months. The performance is up by over 20% on 0.9-beta2.3, which was already a well regarded implementation from dga. For the release it would be great if you could do a direct comparison of the block rate an...

Re: rieMiner - Solo + pooled Riecoin mining

I've disabled the ISPC prime test on AMD, merged up with your branch and submitted the pull request.

I still haven't seen any unexplained seg faults/asserts in my testing. I'll continue to run in gdb and hopefully I'll be able to debug it if I hit it!
