rieMiner 0.92 Revision c is out and binaries are available on Github.

- New assembly optimizations by Rockhawk, improving performance by 10-15% on AVX2 machines - if you like this be sure to donate some RIC to him (his address can be found on his profile)!;
- For Solo Mining, it is now possible to set Donate to 0 without workarounds and donations now go to the Riecoin Funding address ric1qr3yxckxtl7lacvtuzhrdrtrlzvlydane2h37ja rather than my personal address;
- New advanced option RestartDifficultyFactor option to customize when the miner restarts. Notably useful to optimize the Primorial Number a bit by reducing the restart margin, in this case it is a good idea to use GeneratePrimeTableFileUpTo to precompute the Prime Table and make restarts much shorter;
- Now that we have rieMiner-Qt, it makes the configuration assistant basically pointless, so it was removed;
- Some other minor changes.

With the new assembly code, it is no longer possible to compile generic binaries with AVX2 (I am using -march=core2), so one must now compile rieMiner to enjoy the AVX2 benefits with the EnableAVX2 option. This also means that the Enable AVX2 check on rieMiner-Qt will also no longer work.

I would gladly build 0.92d and later using -march=haswell or so, but apparently some still mine on old Ivy/Sandy Bridge or even Nehalem CPUs, even recent Pentiums/Celerons do not have AVX2, and only a minority would bother building rieMiner...

Darn, I realized that one of the modifications causes an issue when running multiple instances of rieMiner. So I fixed it and am already releasing the Revision d. It also adds Primorial Offsets for 7, 8 and 9-tuples, allowing up to 64 Sieve Workers.

Improvement ?

Hello, why do not sieve the program 10 condotions and prove the first 7 and than 8,9,10,... so the ratio is not ~60 , it is maybe just 30. So 8,9,10-tuplets are earlier ?!

BTW, I'm the successor from Tony Forbes' prime k-tuplet page.

Welcome here Norman, and glad to see that you are regularly updating the list with new 9-tuples and large 8-tuples from Riecoin.

I am moving this discussion to the rieMiner's topic as it is more about the its default settings than the Riecoin Protocol itself.

The Riecoin Protocol only requires 7-tuples for its PoW, so the goal for a miner is to find as many 7-tuples as possible. It is up to them to choose whether to sieve for longer tuples.

With the current Difficulties, doing so will decrease the 7-tuples rate a lot. I ran some simulations at Difficulty 1024 and if sieving for 8-tuples with good settings, it is ~2x slower to find 7-tuples while ~1.6x faster to find 8-tuples and longer for my computer. If sieving for 9-tuples, it is ~4.5x slower to find 7-tuples while ~2x faster to find 9-tuples and longer. The calculations assume a ratio of 64 if not sieving (about equal to the number of 7-tuples divided by the number of 8-tuples found so far). I did not ran for 10-tuples, but we would find even less 7-tuples, and maybe about 2x more 10-tuples as well.
The results would be worse for current Difficulties around 920.
So if we sieved for 9-tuples, we might get more 9 or 10-tuples, but not much more. And they will be smaller because the Difficulty would adjust to the lower 7-tuple rate, so less interesting.

Things would be much more interesting if the Difficulty increased a lot. Around 1536, we could start considering sieving 8-tuples by default on rieMiner as it would be only ~1.3x slower to find 7-tuples while ~2.6x faster to find 8-tuples and longer. If sieving for 9-tuples, it would be ~2.2x slower to find 7-tuples while ~4.6x faster to find 9-tuples and longer. The calculations assume a ratio of 1.5*64 = 96 if not sieving, maybe it would be a bit lower due to the use of larger Primorials.

At 2048, the performance loss of sieving 8-tuples would be negligible (a few %) while 3.2x faster to find 8-tuples and longer so we could definitively do it by default. Sieving for 9-tuples would be only about 1.3x slower, while increasing the rates of 9-tuples and longer by about 10x. Calculations assuming a ratio of 128 if not sieving.
11-tuples (if we changed the default Primorial Offsets) might still always require decades to be found regardless of the Difficulty and sieving...

In these situations, we could find so much more interesting constellations, but there is a really long way before reaching 2000 levels, it would require about 1700x more mining power compared to now, unless one finds significant improvements for the Sieving phase...
Everyone, keep mining and spreading the word!

A new stable release is out: rieMiner 0.93. Updates since 0.92 Vanilla:

- Improvement of assembly optimizations (+10-15% with AVX2), removal of the EnableAVX2 option (now always enabled in AVX2 builds);
- Now possible to configure rieMiner via Command Line;
- Bug fixes, especially for Windows;
- Remove the configuration assistant as we now have rieMiner-Qt;
- Add pauses to reduce confusion (notably, giving most Windows users a chance to read messages about wrong configuration);
- Support of the Stratum Client.Show_Message method;
- Many more Primorial Offsets are now hard coded (useful for people having a lot of Cores);
- Replacement of the Test Mode by a separate testing server for easier and much more realistic and complete testing;
- Networking code rewritten and much improved, Jansson replaced by NLohmann Json;
- There are no longer separated Light and Android branches, everything was reunited in Master. Easier build procedures;
- Other minor and aesthetic changes.

The rieMiner binaries are now hosted on Find the links to the latest version here.

Happy Mining!

Time for a small revision 0.93a.
As always, download the newest binaries here.

Changes from 0.93:

- Fixed a bug;
- Total Physical Memory is now a factor used to determine the default PrimeTableLimit, which should no longer have to be set manually if having less than 8 GiB of Ram;
- No more donation;
- Added a basic rieMiner Api, initially to help HiveOs integration;
- Build system significantly changed, now using Cross Compilation not just for Android, this makes the creation of official binaries much easier. Msys is no longer used/supported;
- Some other code improvements.
