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

[chrysophylax]

After vidarn, I just beat the world record of prime 8-tuplets using rieMiner ! The octuplet was submitted to Tony Forbes, who confirmed its validity and listed it on his website showing the largest known prime constellations.

The processor was an AMD Ryzen 3700X @ 4 GHz and it was estimated to take about 17 days to find such octuplet. However the run took about 24 days.

Hopefully breaking new records regularly with rieMiner will eventually attract some interest in Riecoin software and skilled developers having experience in other prime number related software!

A #competition channel was opened in Discord in order to discuss about tuning or improving rieMiner to make it even more competitive for beating world records (and efficient for mining). If you are interested in taking part of this fun competition, or a developer interested in improving rieMiner, you are more than welcome to post there! Anyone with a very good CPU can participate.

How do you set the miner to do this? ...

I am quite interested.

#crysx

If you wish to enter the competition, below is what I wrote in #competition in Discord.

If you want to take part of this competition, the important parameters in the Config file are

- Threads, BenchmarkDifficulty, ConstellationType (set how many threads you want to use to find a new record and your goal: which type of constellation and the length of the prime numbers)
- PrimeTableLimit: higher is better until a given point; the more the Difficulty, the higher the PTL should be. But with over 16 Threads or very low Difficulties, you may need to reduce this value a lot to avoid CPU Underuse
- PrimorialNumber: higher is better but the primorial must be smaller than the prime numbers you are looking for by some margin (~65 binary digits), otherwise the search will not work or loop
- PrimorialOffsets: pick numbers compatible with your Constellation Type (normally, you can simply use the first constellations' base primes)
- SieveWorkers: increase if you are affected by the CPU Underuse, lower is better
- SieveBits: higher is better; 2^SieveBits times SieveWorkers should be a number of bits that fits your L3 cache

Developers are welcomed in order to simplify the tuning by improving rieMiner (especially by definitively fixing the CPU Underuse Bug).

Currently, the easiest record to beat is still the 8-tuples. One can beat my record in about 25 days with a 3700X using a Difficulty of 1075 (my record is 1025).
The 7-tuples record can be beaten in about 50 days at Difficulty 1800 (current record is at ~1750)
For 6-tuples, it is much harder and it would take 1.5 year to find a one at Difficulty 3500 (current record is at ~3445)
For 5-tuples, it would take ~250 days to find one at Difficulty 5400 (current record is at ~5335)
Starting from 9-tuples, the CPU Underuse Bug strikes back, forcing you to use very low PTLs. It could still find a 9-tuple at Diffitculty in about 30 days at Difficulty 700 (current record is at ~675)
For 10-tuples, it would take ~40 days to find one at Difficulty 480 (current record is at ~455)
For 11-tuples, it would take ~150 days to find one at Difficulty 380 (current record is at ~360)
rieMiner is not really viable for 4-tuples and shorter and 12-tuples and longer as it would take about a decade or more to find anything...

There is a small room if you want to beat more easily records, though records by small margin will be less interesting. And of course if you have ThreadRippers or other computer beasts, you could beat records in much less time. But there is also a lot of variance so it might take much more time than estimated, or in contrary you might be lucky and find a tuple much faster than expected.

Good luck!

I will add that it would be better to try to beat records that are not already owned by someone that used rieMiner, I suggest to try to beat the 9-tuples. Vidarn told me that he is trying to beat the 6-tuples record (good luck!).
If many records were broken with rieMiner, it would surely attract more interest in it and Riecoin.
Example of rieMiner.conf for 9-tuples that works well for me (3700X), adapt it to your system

Code:

Mode = Benchmark
Threads = 16
PrimeTableLimit = 25165824
BenchmarkDifficulty = 700
Benchmark2tupleCountLimit = 0
TupleLengthMin = 8
PrimorialNumber = 89
ConstellationType = 0, 2, 4, 2, 4, 6, 2, 6, 4
PrimorialOffsets = 182403491, 226449521, 910935911, 1042090781, 1459270271, 2843348351, 6394117181, 6765896981, 8247812381, 8750853101, 11076719651, 12850665671, 17140322651, 22784826131, 24816950771, 33081664151
SieveWorkers = 10
SieveBits = 24

For example if you had a 3900X, you would use 24 Threads and probably have to lower the PrimeTableLimit (or increase the SieveWorkers)
The tuning is really Trial and Error in order to get the best efficiency.
The PrimorialOffsets can be filled with the numbers found here (for other tuples, just search for things like "septuplet", "octuplet",... in the website, be sure to pick the right ones)
Don't discard the 8-tuples (or (k - 1)-tuples) as you can submit them as well and get easy 5th place.

Another exchange Riecoin might be listed on for free:

https://qtrade.io/listing_guidelines

They listed Bitmark which was also delisted from Polo.  Riecoin has a good chance of being listed there as well because it's no longer listed on a big exchange, just like Bitmark.

Quote that can be found in the guidelines I linked above:

'Not listed on top exchanges – qTrade is growing and assets listed on exchanges with more volume don't benefit much from listing with us.'

I remember reading somewhere in this thread that there is a closed source miner that achieves around 20% better performance.

It's porbably because of a "continue" statement instead of a "break" when verifying primes in verify_thread in riecoinMiner.cpp: https://github.com/gatra/fastrie/blob/stratum/xptMiner/xptMiner/riecoinMiner.cpp#L451

This causes the miner to check the primeness of every number in the tuple, even when the tuple cannot be a valid share anymore.

Since the mpz_powm operation is where most of the time is spent, this can have a significant performance impact.

You are right, it should indeed be a break statement, I just fixed it in rieMiner. Good catch! This improves the performance by about 5% without having to change anything at the pool's end. However, you should no longer use the outdated Xptminer...
With this, the other pooled mining issue is less affecting performance, but my suggestion of requiring that the first 2 numbers must be prime would still help making pooled mining more efficient (both issues overlap while still being distinct).
None of the changes will affect Solo Mining, though.

The only person that proposed a closed source miner and claimed a 20-25% improvement was someone that was hostile to the Riecoin community, and that is no longer around (Simba84/RiePool). There were no actual way to prove that the miner was actually more efficient, and this person pretended that it was rather due to some advanced Assembly optimizations...

Now, rieMiner was involved in a third prime constellation record, as I beat the world record of prime 9-tuplets ! The nonuplet was submitted to Tony Forbes, who confirmed its validity and listed it on his website showing the largest known prime constellations. It has 214 digits (Difficulty 709), while the previous one had 203 digits.

The processor was again an AMD Ryzen 3700X @ 4 GHz and it was estimated to take about 30 days to find such nonuplet. I was this time luckier as it took instead about 15 days.

If there are people interested in beating these records, they are more than welcome!

Great news, thanks for your work ...

There is another good news coin riecoin rose to 3rd place on the list to be added to the exchange https://www.southxchange.com/Home/Vote#new-coins I ask everyone who can vote for our coin to take part in the promotion. in case of adding to a given exchange, the price of a coin will rise very much!!!

P.S. I want to clarify - taking into account the cost of the SXCC coin of 100 Satoshi, to add to this exchange you need only $ 200 (250,000 SXCC) - if everyone pays 10 dollars, then 20 people are enough to reach this amount ...

sorry for my english - google translator

Unfortunately, your math is off, 250000 Sxcc is actually 10 times more than $200...

Hey guys! Now I checked my wallet on cryptap.us there is empty. Did i miss something? Although https://chainz.cryptoid.info/ric/address.dws shows a normal balance. How to regain access to me riecoins? Thanks in advance.

You will have to import your private keys into riecoin-core with importprivkey.

Hello, there is great news for the Riecoin community, two days ago a large sum of 71,000 SCC was made for listing on the https://www.southxchange.com/Home/Vote#new-coins

I want to thank the unknown virtue for such support !!! At the moment, riecoin is in first place in the list to add.

I recommend that all Riecoin holders remove sell orders at low prices, and wait a little longer and do not restrain a possible price increase (I removed all my sell orders in anticipation of a strong pump) When the coin is added to the new exchange, the price can rise very much !!!

[megaminer2017]

Hello everyone, great news for all riecoin coin holders !!! our coin will be added to the exchange https://www.southxchange.com/Home/Vote#new-coins yesterday someone contributed the missing 150,000 coins for placement on this exchange and today the exchange will begin the placement process !!! I advise everyone to buy some riecoin coins until the price has risen very much !!!

p.s. Thanks a lot to the unknown virtue who contributed the missing sum !!!

You can now trade RIC in SouthXchange!

• RIC/BTC market https://www.southxchange.com/Market/Book/RIC/BTC
• RIC/LTC market https://www.southxchange.com/Market/Book/RIC/LTC

Thanks to everyone who contributed to the listing fee!

In comparison to previous exchanges where Riecoin is listed, SouthXchange is a major one, providing more liquidity, which will likely help to stabilize the markets and increase the RIC value.

But it is only a first step, and we still have a lot to do: getting listed to more exchanges, improve our software, spread our project, and more! We are as always looking for new developers!

[megaminer2017]

You can now trade RIC in SouthXchange!

Great NEWS !!!

[megaminer2017]

there is one more good news resumed work of twitter account https://twitter.com/riecoin

p.s. great news, if the main site is still revived ... I ask administrators to post such news on all project sites - not everyone is discordant, I used to learn information only from the forum  https://bitcointalk.org/index.php?topic=446703.6100 ...

Coingecko is now tracking southXchange pairs for RIC
This should also reflect on miningpoolstats.
As soon as we get a bit more volume, we should be able to request the pair added back to coinmarketcap

Hello everyone!

If i do regular mining can i run for the record or must be only in the benchmark mode, and if i find the block in benchmark mode is it seen in the wallet?

It must be the Benchmark Mode. We would need much more miners to hope to break the 6-tuples record by mining RIC.
No block is mined in Benchmark Mode, it is independent from the Riecoin blockchain.

And yes as Pon13 said, if you wish to beat a world record using rieMiner, the best is to join Discord to discuss about it.
