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

[zawawa]

You guys are right. I decided to spend the whole day with my wife today.
Let me just finish a new implementation of parallel writes before she gets up, though...

[ioglnx]

You are begging for slaps

[zawawa]

I just pushed the new implementation of parallel writes.
My RX 480 is doing 183 sol/s now.
I think my wife is getting up. Gotta go now. Ciao!

Code:

In file included from main.c:33:0:
main.c: In function ‘tests’:
main.c:1858:9: error: ‘NR_ROWS_LOG’ undeclared (first use in this function)
  assert(NR_ROWS_LOG >= 12);

I simply removed the function "tests" and the call to it and it compiles and runs...

I just fixed it after a long morning walk with my wife. Thanks for letting me know!

My wife is now constantly complaining about my forgetfulness and absent-mindedness, but that's OK...

my wife does the same, and i dont code, i just mine.......

btw those long walks with wife do wonders

Walking also good if you sit at a desk a lot.  You should also do hand and arm stretches, and try to stay active.  I learn some of these things the very hard way....  It is easy to get lost in code though.  It is not uncommon for me to forget lunch, when you are on a roll coding.  Just don't get too involved for long periods of time (like weeks).

Awesome job so far...your miner is now just as fast as optiminers (if you factor in his dev fee speed he is still slightly faster, but regardless this is still nice work). 470s are now doing 170 with this miner (and your only 40S/s away from claymour). Will def send some btc your way.

[zawawa]

I just uploaded a new release with precompiled binaries for Windows:

https://github.com/zawawawa/gatelessgate

188 sol/s on RX 480 and 165 sol/s on GTX 1060 3GB.
Pretty good given the fact that I haven't touched a GCN assembler or PTX.
I am also thinking about swapping gatelessgate.py with sgminer-gm.
We will see how that goes.

Yeah, I need to slow down a little bit. Not too much, though.
After Equihash, I would really like to look into Ethash and CryptoNight.

Thanks! That would help me to buy more equipment for testing.
I really want to test this miner with high-end cards.

cryptonight for nvidia would be awesome, it is totaly untouched for the moment , latest miners comes from 2014 (tsiv/klaus) and underperforming alot comparing to amd.

Tested it with OC-ed 1070
2 instances 300sol/s
nicehash  410sol/s

If I up the threads it give only 0sol/s

looks like windows build use some CPU 20% for instance on i5 CPU

Not bad, not bad. You just need to increase the number of instances for high-end NVIDIA cards, then.
For some unknown reasons, WIN32 threading does not work with NVIDIA drivers. Strange, strange...

Try with instances instead of threads.

Yeah, "--instances 2" did work with GTX 1060 and is now the default setting for the NVIDIA version.
I should mention this somewhere in the documentation...

1070 micron 2050/4400/75%tdp, cpu g1840, Win8.1

With single card - it is possible get up to 290 s/s, but...it has high cpu usage - load at ~90%. With 3 cards I can get ~275 s/s for one, and with 6 cards - only ~220.
Tried with different threads/instances parameters and all has high cpu usage.

Thanks for the report. I guess the current CPU usage fix does not work too well.
I will look into this problem.

And - 0.3 miner not working with 280x: crash right after start with error "sa-solver.exe has stopped working" for each gpu.

Thanks to my eidetic memory I remember what was needed :-D
