Topic: [ANN][GAP] Gapcoin - Prime Gap Search - New Math Algo - CPU / GPU - Zero Premine - page 5. (Read 286844 times)

The problem with releasing a coin without an optimized miner is the person who develops and optimizes a GPU or FPGA miner will not release it publicly lol.  They will just eat everyone else's lunch.  This is what is currently happening with RandomX, but good luck nonetheless.

AWOL, but glad to see good progress and that everyone is getting along so swimmingly!  


@gjhiggins - Can we all now safely assume (as per https://gapcoin-project.github.io/), that;

1. This repository: https://github.com/gapcoin-project/gapcoin-core.git is now the main Gapcoin Core v0.16.3 source / release?

2. This repository: https://github.com/gjhiggins/gapcoin-core is very much a 'work in progress'.

3. This repository: https://github.com/gapcoin-project/gapcoin is for v0.9.2-3 and that the experimental v0.9.4 source should generally be avoided.

4. The v0.16.3 source / binary releases would generally now be advisable over running v0.9.2-3 for anyone starting afresh with Gapcoin / Core / Solo  / Pool Mining ?


Cheers!

P.S. I'd also like to know the odds on @UsernameNumber7 being an alt. or crony? of @Vlad2Vald ? (which would explain a lot ...)  

Hey,

thanks for your intervention.
Indeed, tests/sec increment instead of displaying correctly, but we can get used to it with some patience.
The CRT miner is far from its full potential, but J0nn9 couldn't improve it further, from what I read.
But anyway, we can now largely confirm that it's "efficient", with the right parameters.

Thanks for the tip, I'll adjust that.

If "Supercomputing's claims are perfectly legit", then I hate him. What a waste..  
Anyway.

I know this is a bad comparison, but seeing what other researchers manage to produce by focusing on record improvements.
I see (potentially) bigger things for Gapcoin.
By being on the right point in space-time, and if a few stars can align, who knows.


I'm hopeful for Gapcoin in 2021.
Who knows what can happen.

Hey Wizz,

Thank you for your efforts and for posting your CRT@Ryzen stats! Please notice that tests/sec metric reported by the original CRT miner is plain wrong, so please add "n_test = 0;" after "cur_tests = (cur_tests + 3 * n_test) / 4;" in ChineseSieve.cpp and recompile.

Please also be advised that both CRT-miner and GPU-miner have been provided by j0nn9 as a proof of concept and were not intended for production runs! CRT-sieve may need to be rewritten, otherwise running the original CRT-miner makes little practical sense. In the meanwhile, it may turn out to be more efficient to concentrate on improving CRT offsets for higher shifts. CRT offset generator is also a proof of concept to some extent, but it may produce useful results nevertheless.



I have reasons to believe without doubt that Supercomputing's claims are perfectly legit. It is extremely unfortunate that other commitments prevented him from contributing to the GapCoin project openly.

Stop google translate. Dumbass. No one r*ped no one, that was a joke.
I tried to be constructive, to help you. To help Gapcoin.
We are all making an effort, wasting time with you. You must take a step towards us.
I leave it here for others.



The long lines are the blocks that I produce (for the pool) now @shift 1024.
As you can see, the rate (compared to the whole network) is good for 2 cpus using CRT.
I would be happy to have a "challenger", it would be fun. But we need to cooperate.
So we'll see records in a while. As you say. Let's wait together.

I renew my offer to reward the improved records in higher shifts. (Except Username7, unless he apologizes.)

Edit:
I just noticed that.  
What a sense of observation.

Two fresh ones for me.
24334,C??,27.442008,Gapcoin,27-04-2021,386,128071..
23290,C??,26.280766,Gapcoin,28-04-2021,385,743900..
And a fresh one for you, nice.
8418,C??,29.083531,Gapcoin,28-04-2021,126,5048105.. Block 1419552

 
It's Wizz.
It's almost guaranteed (at some point) when used in the right way.
But it's true that Gapcoin needs A LOT more computing power, and it's not an individual effort.

--shift 160 --crt crt/crt-22m-160s.txt --threads 12 --fermat-threads 11 --sieve-primes 5000  
This above gives me "16500 gaps/s 4M tests/s 0.09%", with my i9-9900kf with only -t 12, using CRT. (Shifts 128-256 are the minimum shifts to use CRT, for me)
 
How is it possible to have only 1M PPS ?! Without CRT ? Using standard miner ?
Sounds like a Joke, if Yes. Kind of inefficient/at the limit, I mean...you can improve your performances with this cpu. We could help IF YOU EVER JOIN DISCORD !
First Performance drop @shift 64 (I think there is another one around shift 128, not sure)
Anyway, PPS isn't a good value to look at, regarding the miner or the settings. (I can get more than 200M PPS, at some point, using CRT and the pool...?!)
To compare properly :
Tests/s is the universal/real performance value, as I saw, for every version. (even gpu)
Gaps/s is good to look at, with rev5.1, with or/and without using CRT. (Different ouput between rev5.0 and rev5.1, without CRT)

"I have lots of Prime Gap Records using Yitang Zhang mining algo using high RAM."
 
Not sure what that means(and what RAM has to do with gapminers...I asked myself and tested it but I don't get it), but do you know that we see it all, right?
(in live, even some of the stale/orphan/bad blocks)


Here is what we can see for the shift 160-162   :

"Prime Obsession owns the overall record!"
 
Hum maybe, but I doubt that PrimeObsession is Andrey Balyakin. If yes okay, good to know.
I know Prime Obsession's Gapcoin main address.

https://gapcoin.org/primegaps-length.php
 
is deprecated and shouldn't be used anymore. But the PrimeGap List :
https://raw.githubusercontent.com/primegap-list-project/prime-gap-list/master/allgaps.sql

"Most all the records other than shift 25 are either mine or Prime Obsession's!"
 
Nop Sorry. At least, not anymore. M. Loizides r*ped us  
https://primegaps.cloudygo.com/graphs?max=32000

"I don't think the CRT miner produces any good records!"
 
Shares, Blocks, Records. It does.
FYI
Shift 768 without CRT :


Shift 928 using CRT :


Seems pretty obvious.


Getting back to the records:
We'll keep getting r*ped. (Yes I'm abusing a bit, it's true.)

As M. Higgins said :
"They're oriented on finding new records, Gapcoin merely uses prime gap search as a Proof-of-Work. The size of the record known first occurrence prime gap list has expanded dramatically since 2014."

And it's true. We are just raising the minimum threshold (minimum numerical limits) for records. This is not the most motivating aspect of Gapcoin, for me.
It's like cleaning up after the others have had fun at the party.  

Gapcoin NeEd PoWeR !! WaY, wAaYy MoRe pOwEr !!
1000M PPS or so... not 30 or 48 ... (nor 100 or 300, btw) to find/improve records, now.
(300M PPS would correspond to a difficulty of ~24.5, "only".)
Blocks with merit of 27 or 28 should be much more frequent. I'm hungry, I want more.


(PS:
Settings for gpu miners should appear soon. -w and -n seems to be useful.
A little 'surprise'(I hope lol) could also(I hope too lol) happen soon. Shh)

Nice Job Whizz, I don't ever test Shift 25............3 Million for 12 core is nice!  But Hash rate does not guarantee a winning block.  


16 Core AMD 3950X mines Shift 162 around 1 Milltion PPS.  Using 20 GB Ram.

I have lots of Prime Gap Records using Yitang Zhang mining algo using high RAM.


Prime Obsession owns the overall record!  Looks like Jonn9 might be late listing the new records from 2020 year

https://gapcoin.org/primegaps-length.php



Most all the records other than shift 25 are either mine or Prime Obsession's!  I don't think the CRT miner produces any good records!

Okay, not bad. Running with a random 250w power supply, it does the job.
The motherboard is fine and allows to tune, but I propably won't.

Buit-in miner :
3.3M PPS & ~1M tests/sec  @67°c



CRT @shift 1024 :

Yes is a mess, its copy of xpmminer code.

The code is faulty. there are 100 lines of coide that should be reducet to around 20. It picks up that text in that mess but it seems not to have any impact at all. .

Latest Gpu miner is rev4.1.
Where you get "Error AMD accelerated parallel processing found" ?
If you trying for NVIDIA you must use --platform

I have looked a little more at the gpu miner code.

It seams to be a mess.

I looked at the following code and could not understand why the miner prints out "Error AMD accelerated parallel processing found". I saw that he did not care if it was a AMD or Nvidia but how could it drop down to the last else and get the error.


if (strcmp(platformId, "amd") == 0)
    platformName = "AMD Accelerated Parallel Processing";
  else if (strcmp(platformId, "nvidia") == 0)
    platformName = "NVIDIA CUDA";
  else {
    pthread_mutex_lock(&io_mutex);                            
    cout << get_time() << "ERROR: platform " << platformId << " not supported ";
    cout << " use amd or nvidia" << endl;
    pthread_mutex_unlock(&io_mutex);                      
    exit(EXIT_FAILURE);

Also he don't use the exit somewere else. He don't check for the cards before this code executes. So this piece of code is not useful for the program.

Then I started to read more. There are over 100 lines of code that are repeating itself. Checking the cards again and again. Also the fact that some old code in pthread also could course problems.  I'm not a c or c++ programmer so I maybe can't fix all of that. It's probably a cut and paste problem that left so much faulty code there.  

I was only trying to fix faulty math against graphic cards and compile it. If it don't make harm I leave it in there for now.

  
I could not find any later gpu miner than 4.1 to work on. So if I'm wrong about that then point me in the right direction. This one I'm looking at. https://github.com/gapcoin/GapMiner

I said that I probably will fail.   All that faulty code don't make it easier.

That binaries that are on github are diffrent in execution than that Graham are using. Maybe they have updated the phread so it works better. I'm cconfused.

It's got some life in it yet. Wizz has generously funded the chainz block explorer until 2022-07-09. I'll continue making technical contributions where I consider it necessary to maintain the codebase. Freiexchange has been seeing some recent interest.

Cheers

Graham

I have looked into how to change some code for the miner and compile it. Windows can't be used. I probably can use one of the latest Linux distros but maybe it's safest to use the same as the wallet are compiled with. I know were the problem are but I don't know how to fix it. I have been searching for a similare problem but most info are about DAG and ETH. 

I'm not a  c or c++ coder. I have never done any work with wallets or miners. So I probable will fail. That teases me is that I see what the problem is. There could be other problems that show up if I solve the first one. Both my nvidia cards are reported as  Error AMD accelerated parallel processing found. So the miner could have  much more problems. The fermat code seems to be OK. I'm going to set up a linux distro in a virtual box and go "shopping " for a IDE. I'm looking at  Apache NetBeans 12.3,   Code::Blocks , Eclipse CDT, Microsoft’s Visual Studio Code Editor. Have no idea which is the best.

First a polite question: Are you an Russian and are using google translate. ? Because that could explain some things that you got wrong.

First off all you can't see inside a wallet, you just see what it reports. You can have it in a box. Check firewalls, tracing it with assembler. decompile it. The source code you can look at and compile. setting breakpoints and more.

You posted some code and said there was a script. There was none.

What I can see is that he was busy with other things like the static website and life. You are not paying him so he can't work full time with this. One wrong line of code and you have a bug. This bug caused a user to send coins to a burn address. That bug happens in the worst place.

That wallet is a experimental wallet which means that you mostly use it on testnet and if you use your wallet  with sending coins to exchanges or other wallets youi should use the last stable wallet. Otherwise just send the minimum amount of gapcoins to test it.

Graham are still working on it and now you are writing that is a bug that did it. Before you accused Graham to steal coins.

First off all you need to know how you can do it right befiore you accuse them off doing wrong. I have seen to many msg from you that are so wrong and sadly very abusive.
So if want to find facts about this projekt then I have to plow through a lot of garbage.

If nobody are developing it and nobody are paying for the explorer then it will be gone.

I am not going to study Mr. Higgins Code?  He has been shilling it for 3 years now??

I SAW from inside the Wallet the code execute to do this the wallet was compiled from Mr. Higgins source code of which?  I don't know any idea where the code would be???  If you got the time you do it!!!!!!

Mr. Higgins did not even change the malicious code until after some weeks until I pointed it out??  That is the only way I knew where the code was?  

5900x 12 core would produce probably 1.5M!


1: Mr. HIggins threatened to delete this 16.3 Repository after the "Bug".  

2: Mr. Higgins had declared a Hard-Fork 16.3 even while the "BUG" was still in his source code?  Until I reported it?  

it is possible for someone to integrate this currency on https://bscscan.com ..like all coins from https://pancakeswap.finance , good volum for all coins here 

I have just put in two hours of thinking on this but I'm sure the problem lays in that the chunk of data is to big to fit into the device memory and should be halved. Your approach can possible in same cases fit the end into the memory and create something like a valid test.

Grahams solution seams to be the best because if my solution works then it maybe just valid for the graphic chip I have and also depends on which opencl version on the computer.
..

I tried GTX970, GTX660, GTX750ti... I think I saw every CL error between -1000 to 1000.  
But I'm skill-less for this.

Try -w 32768 or any ridiculously huge value ^^ It will be your best result.

Feel free to come on Discord. Good luck with that, It's definitely possible, with the appropriate skills.
Be aware that only one person claims to have run an nvidia miner. But I don't believe this person.

I tried runing the gpu miner on my laptop with nvidia.I used windows 10. The cl error I got are different than yours. By reading the code I have found the source of my errors.and they don't looks like it comes from the cl implementation but rather from the difference between the hardware of the vendors. It seams the host is writing to much data to the device.
The problem now is that my laptop is broken and I need to get a graphic card to my stationary computer. So I can not go further with it at the moment.

Different nvidia chips could cause different problems as it looks. I'm not good with it,  but I will try to get my hands on some old cards to play with.

Edit:
Graham I checked your errors to and they seam to be similare. Your new computer with GeForce GTX 1060 is not recogniced by the program because it was written long before that card was released. Also the code he used is for a opencl version that did not take care off different hardware very well.
