Topic: [ANN][RIC] Riecoin: constellations POW *CPU* HARD FORK successful, world record - page 6. (Read 685265 times)

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.

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 ...

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.

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.

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

I am quite interested.

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!

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.

Interesting, now that you say this, FreiExchange (and Zapple) are surprisingly listed in CoinMarketCap...
Looks like they do not really enforce the "at least $1000 USD equivalent of daily trading volume" requirement after all.
Though, for the long term, it is much better to get listed in much bigger exchanges than the current ones, for example in SouthXchange, rather than risk to be delisted again from CoinMarketCap...
