Hello, here is the sextuplet record holder.

Hello!

Four years is a lot of dedication, 12-18 core was a sizable amount of silicium back then... and an even more sizeable amount of juice to run them, were they dedicated or just churning on spare time?

(and FWIW Phenom II is still the core of my main work PC, fine CPU, if a bit hot under stress)

Any idea of the hardware he used and for how long? He has some margin!


I got in touch with Norman Luhn, and he gave me this brief:

The titanic-6-tuplet-project was a "dream" of me in year 2000.
I have started the project on Aug. 2011. After 4 years I found it after 153 quintuplets. The hardware is normal, 12-18 Phenom II cores at 2.8 GHz. I wrote a presieve for APSIEVE. It was a hard job :-) to sieve in 10,000 4-billion-blocks before I found it. I looked for k's in an interval 0 up to 10^14.

Since he just signed up for this forum, you can probably discuss other details with him directly.

The number above corresponds to a Riecoin difficulty of 3444.
Wow!

That's about 50% higher than current super-blocks, which might be stretching the monetary purpose of RIC a bit, but would still be feasible I guess. Too bad it would take a hard fork...

I wonder if there could be a way to "vote" for super block difficulty? When bitcoin miners are considering voting for block size, RIC miners could vote for the superblock difficulty multiplier.

This could allow some super-super-block to be voted by miner consensus, to claim a world record, and then miners could resume "normal" difficulty.

congratulations to all

Congratulations for what this new record was not found by the ric network.

Hi all,
The 6-tuplet world record has been broken again, thoroughly:

The previous record was 751 digits, Norman Luhn's new record has 1037 digits.

The first titanic (more than 1000 digits) 6-tuplet record is
28993093368077 * 2400# + 19417
http://anthony.d.forbes.googlepages.com/ktuplets.htm

Norman is a veteran prime record breaker and held a lot of the previous 6-tuplet records.

The number above corresponds to a Riecoin difficulty of 3444.
Wow!


Sounds like a challenge too me!

Well, as it is common in the world around, the success comes with a price.
I have a stratum pool open here :
https://bitcointalksearch.org/topic/m.14014382
No problem with DDOS, but no miners as well.
Maybe over the weekend Smiley

it's still ongoing? that's insane.

I guess from the silence everything is running smoothly now and the ddos are over?

Also my pool is often under attack! I don't understand why someone wants to sabotage this great project...

Please stop and look elsewhere, or mine Riecoin like everyone else!

Thank you

DDoS attacks never stopped since i started the pool. Day by day, hour by hour. Im 24/7 monitoring the pool.

What the hell is this guy wining with this?

RieCoin is getting back on track in the world record race: the top 3 largest prime constellations were found in februrary with a nice trend.
IIRC world record is at 751 digits, so well within reach!

checking my mailbox - nobody is interested in private test.

I am happy another mining portal is alive,
 my humble miner is here to help Smiley

Hello.

I am newbie to the RIC.

I am wondering that How can i optimize my miner for using all of my CPU resources??


When I start mining using the xptminer, the miner only use 5 thread...
But my CPU is E5-2667 V3(32core)...
So, I should use -t 32 option, but my cpu utilization(load average) is only 20.

Does anyone know that how to set cpu threads for mining properly and the sieve value?

For mining on machines with multi cpu for best performance, u should launch one miner for each physical cpu and tie the process to each physical core using either numactl for linux or start affinity for windows.

Hello, welcome to the Forum.

For the use of cores try to start more xptMiner (4 or 5) without "-t" parameter, while for the Sieve Size value if you have a RAM of at least 16GB you can set a value as "-s 3500000000" or "-s 4000000000" (3.5 / 4 billions)

Good mining!

Hello Simba.

I downloaded the xptminer from "https://github.com/gatra/fastrie". And i have already used the xptminer without "-t" options for using all cores.
But the xptminer did NOT use my all resoures of cores.

Moreover, I have big amount of RAM about 192GB ~ 512GB in each machines.
So, How much do i set amount of RAM to my machine??
Do you have any idea??
For best performance do this:

For Linux 64bit OS:
Download xptMiner2 binary: http://riepool.ovh/downloads/New_Linux64_xptminer.zip

For Windows 64bit OS:
Download xptMiner2 binary: http://riepool.ovh/downloads/New_Windows64_xptminer.zip

Script: xptminer2 -u username.worker -p password (-t CPU threads number) (-s sieve size)

For Linux, give permissions to downloaded file with the command: "chmod +x xptminer2"

It's currently the highest performing miner for Riecoin.

The miner has been extensively tested by many users and works very well.

For the CPU if you use a Cloud or VPS system, check the available vCore and even threads per core via the Linux command "lscpu".
If you get one Thread/Core this could be the problem...
