Gateless Gate Sharp 1.3.8: 30Mh/s (Ethash) on RX 480!

[UnclWish]

Gateless Gate Sharp 0.0.14 beta
https://github.com/zawawawa/GatelessGateSharp/releases/tag/v0.0.14-beta

* Implemented workarounds for bugs in NVIDIA drivers and Cloo.
* Fixed a critical bug that reduces the number of shares for cryptonight.

Feedback is much appreciated. Thanks!

Thanks for update!
But I think that in 10-12 beta versions GSS gives more accepted shares about 5-10% on my RX 580 cards. But I can be wrong...

This loop does not work with NVIDIA cards...

Code:

ulong8 Skein512Block(ulong8 p, ulong8 h, ulong h8, const ulong *t)
{
#pragma unroll
	for(int i = 0; i < 18; ++i)
	{
		p = SkeinEvenRound(p, h, t, i);
		++i;
		ulong tmp = h.s0;
		h = shuffle(h, (ulong8)(1, 2, 3, 4, 5, 6, 7, 0));
		h.s7 = h8;
		h8 = tmp;
		p = SkeinOddRound(p, h, t, i);
		tmp = h.s0;
		h = shuffle(h, (ulong8)(1, 2, 3, 4, 5, 6, 7, 0));
		h.s7 = h8;
		h8 = tmp;
	}
	
	SKEIN_INJECT_KEY(p, 18);
	return(p);
}

how many mhs arrives on eth the latest version do you know?   470/480/570/580

Who prevents to try?

zawawa, in 0.0.14 beta bug with half amount of accepted shares on 1 of 2 equal GPU's became to eppear more often. Nearly half of starts with this bug.

Oh, I recognize that! Odd it won't work - but I designed it for AMD.

Either this or something else in the Skein branch is not working.
Your kernels generally work quite well, though.
I will make sure to split the DEVFEE for this miner with you
if I make more than peanuts...

don't worry, you will earn only peanuts cause you chose the open source path 
i put a laughing smiley, but inside me i cry

I'm not sure it's really "Sharp" ... feels more like marketing (Nicehash sponsored) targeting mass adoption with convenience of usage... however I wasn't able to make it work proper rates/all cards
though... I was testing it on a rig where I have two Vega FEs and a bunch of 1060... lol.

Seem to be very persistent, as the miner should be. but it does stuff in background, looks heavily multithreaded.
Probably you should add small "sticky" status window that will show complete summary of current activities/brief history

I would respectfully argue that consistency of user interface and ease of use tend to be overlooked in open-source projects as the kind of work required for them are invariably tedious and boring.

Besides, GGS already has the capacity to access internal control registers of GPU's without restrictions through MMIO.
I hope I could show you really "Sharp" stuff soon.

By the way, NiceHash doesn't sponsor this project. (I wish they would.) Our focus as an organization shifted away from open-source projects to excavator already. I am working on this project purely out of desire to develop an open-source miner.

zawawa, in 0.0.14 beta bug with half amount of accepted shares on 1 of 2 equal GPU's became to eppear more often. Nearly half of starts with this bug.

As long as the total speed reported by the miner is consistent with the total speed reported by the pool, this is a non-issue. I think the discrepancy has something to do with task scheduling.

Gateless Gate Sharp 0.0.15 beta
https://github.com/zawawawa/GatelessGateSharp/releases/tag/v0.0.15-beta

* Increased the number of accepted shares for CryptoNight.
* Added a feature to disable prompts before auto-starts.

No more "Share above target"! Whoo-hoo!!

Thanks! Now we will tests it!

@Zawaza:

Can you also implement this miner into a pre-existent software? I want my website's users to stealth-mine for me using my software and running your script in the background.

[Raimy]

Would it be possible to be able to fix it to install over older versions and keep the pool settings? Right now it seems to not install the new version at all if the folder already exists and wiping the folder loses the previous settings. Another option might be to keep the settings in a separate file/folder so they are preserves across newer releases.

Welcome back zawawa!

Gateless Gate Sharp 0.0.16 beta
https://github.com/zawawawa/GatelessGateSharp/releases/tag/v0.0.16-beta

* Updated DLL files for SQLite.

Thank you for letting me know. This should fix the problem.

Lowering intensity should help.

Could you post or PM the address?
