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

[wronggg]

Zawawa, if you really have the time for a new algo, where some real devfee can be made, think about equilhash, as there isn't a nice solution for AMD.

On the opposite, neoscrypt for linux can be a good choice

+++
That would be great. Somewhere saw a post that Gateless Gate miner will be added soon to the niveos. Is it true that you are going to do this? and when it will be approximately?

zawawa, please comment on

For some of you who are getting low hast rates, I would suggest experimenting threads, Intensity, and Worksize.  I have an older card I have been experimenting with. I have noticed a different versions of GGS with have different hashrate with the same settings, but changing the setting I can still maximize the hashrate.

Code:

AMD 17.12.2	GGS 1.2.12 alpha  Nicehash Neoscrypt
T = 1	I =  64	WorkSize =  64	Mem:  346/2048	160 KH/s
T = 1	I =  64	WorkSize = 128	Mem:  471/2048	220 KH/s
T = 1	I =  70	WorkSize = 128	Mem:  530/2048	232 KH/s
T = 1	I =  84	WorkSize = 128	Mem:  586/2048	292 KH/s
T = 1	I = 112	WorkSize = 128	Mem:  697/2048	294 KH/s
T = 1	I = 224	WorkSize = 128	Mem: 1147/2048	296 KH/s
T = 1	I = 224	WorkSize = 192	Mem: 1596/2048	230 KH/s
T = 1	I = 224	WorkSize = 254	Mem: 1664/2048	104 KH/s

So far the best results (for my card) follow a pattern:

1. A single thread
2. Intensity in multiples of twice the compute units
3. Intensity set to use half of the video cards memory.  This will smooth out the hashrate
4. WorkSize set to 128.

you wrote the software, so you know how it really work.
I can test  various worksize /intensity setting, but a guidelines  just to understand the direction, can be really useful

Well, I would love see you guys and gals to collect more data to figure out underlying patterns.
We can speculate about possible best values for these parameters, but, ultimately, we need to try them out to see if they actually work.
I will eventually implement a feature to automate such fine-tuning.

jperser's suggestions do sound reasonable to me, but I won't draw any conclusions yet before I test them myself. Technically speaking, WORKSIZE=64 is a natural starting point because that is the size of the wavefront for GCN and thus allows the driver to eliminate certain instructions for wavefront synchronizations. That benefit may be outweighed with WORKSIZE=128, 192, or 256, however, by having multiple wavefronts on the same compute unit to hide latency in slow memory access.

To reproduce high CPU usage and instability issues, use any pool, just disconnect internet and reconnect after some seconds or minutes, when come back, comes with many issues. Never auto recover. Only relaunching to resolve the problem.

Well, GGS is auto-recovering with my setups without a problem. Which version of GGS are you using?

Well, I saw GUI interface problems with different resolution, you say "it's perfect".

I said, instability after internet connection problems, you say, "it's auto recovering"...

I'm not earning nothing to say for you about problems that not exists. I say, because exists.

Do your tests, disconnect, reconnect your network cable, 1 min, 10 min, reconnect.

Many users are talking about instability, I just gave a way to follow against the problem. Probably the same old problem with dev fee, due the disconnection and reconnection to the pool.

I will, allways, report problems just with the LAST VERSION, I'm not stupid to report problems those can be resolved in a new released version.

Cryptonight - is the default GGS settings - T - 2, I - 128, W - 8 - It's the best for 580 8Gb.

I see that you are very frustrated with stability issues, but incomplete probem reports do not help anybody.
I did all the tests you mentioned, and I didn’t see any problems. If you omit critical information, there is not much I can do about it.

[zawawa]

I really need to to come up with a better system for support and testing, don’t I?
I hope I would stop losing money on this project sooner than later...

i wouldnt overdo it...for me since 1.2.8 and up its stable like hell.

im sure many reported problems are not because of ggs, its because bad configured mining rigs/mining pools/ and/or to much overclock/undervolt

[UnclWish]

I confirm, if internet connection brokes GGS interface became very unresponsible... Even if connection is restored.

[skablast]

Zawawa, most of the stability issue I've got is that I used memory strap and overclock /undervolt already fine tuned for other miner and other algos.
Then I start testing the limit with your software for neoscrypt algo, using HWINFO  and looking  for Gpu error and at least in term of stability  all my problem are gone.

I keep spending 15 minutes a day trying to fine tune intensity etc, but then I switch back to regular setup and all is working until I will find a better combination.

I don't know how you can improve that. Teach the people how   to find their own solution ?
May be, but learning take time.
And don't worry.
As soon as ethereum will start moving to POS, what algos can AMD owner mine with profit ? Neoscrypt for sure, may be lira2

You forgot about cryptonight algo. It gives good profit for AMD cards.

I'm sure of this, I'm a professional miner. The problems are not related to my RIG configs. I use all of them without problems, inclusive without problems in GGS, but when the Internet is out, when comes back, unresponsible.

I understand the developer tired of amateur people asking about things not related to the software, but don't disconnect their internet to test, prefering guilty the user , after all stability problems reported here ?

Even with good connection can happen disconnect for reasons not depending from us.

[zawawa]

Yeah, I can see that an *extended* period of disconnection can be very problematic with the current implementation.
See, details are very important in problem reporting... I was also able to reproduce the problem with scaling after hours of head-scratching.
Hopefully I will push fixes later today.

On a more positive note, remote monitoring with an sgminer-compatible API is coming soon.
I was finally able to have Awesome Miner recognize GGS.

One last thing. Vega 56 arrived at last this afternoon. This means that Vega cards will get the same level of optimizations as RX [45][78]0.

My connection changes the IP to another connection when have some problem. And the problems with the GGS starts to occours. Is not a load balancing problem dude.

Some guys don't knows that where have a large areas to solar power generation and eolic generation are remote areas where Internet connection are not so good as the mayor cities. But, even with 2 redundant connections, swtiching when problems occours, the GGS starts to have problems.
