Re: Wolf's MRO CPUMiner - 2x speed compared to LucasJones' - FASTER 06/08/2014
On my i7-2700k@4,6GHz, the latest build
https://ottrbutt.com/cpuminer-multi/cpuminer-multi-wolf-06-09-2014.zip
seems to be slower, 240h/s on may 30 version, 220h/s at best with the above.
More/less cores did not help.
Guessing that Haswells get a boost while old Sandybridges loses out with the new optimizations.

Testing older AMD drivers, by putting the AMD OpenCL (amd_opencl*.dll and amdocl*.dll )files in the same folder as the miner:
13.4 - Gives out of memory errors (GPU memory allocation failed)
13.9 - Similar performance as 13.12
13.12 - Baseline
14.4 - A lot slower, about 25% and gives error codes at startup
14.6 beta - A lot slower, about 25% and complains about "bad performance mode" at startup

14.4 - A lot slower, about 25% and gives error codes at startup
14.6 beta - A lot slower, about 25% and complains about "bad performance mode" at startup
how do you tell how many errors your getting? and what cards and how many??
Getting actual miner error codes with 14.4 driver, as in missing OpenCL function bla bla during start up, still working but slow.
3x 7970 underclocked to 850MHz gets me 825h/s with 13.12 driver, about 275H/s per card@850MHz@0.912V
Trying higher clocks and other driver versions now...
Running AMD driver 14.4 gets me 580 h/s.
Copying the AMD opencl files from the 13.12 driver package to the same folder as the GPU miner gets me 810h/s and less error messages, while still on 14.4 driver
Keep your new driver, download the old 13.12 driver from
http://support.amd.com/en-us/download/desktop/previous?os=Windows%207%20-%2064
and only run the first step of the installer, that unzips the files to the c:\amd folder, then exit the installation.
Then copy the amdocl* and amd_opencl* to the GPU miner folder from
c:\AMD\Support\13-12_win7_win8_64_dd_ccc_whql\Packages\Drivers\Display\WB6A_INF\B165829\
Would be nice to have the files included with the miner, but I guess there is a small copyright issue...

Re: [ANN] [SKC] Skeincoin | Skein-SHA2 | CPU mining | GPU miner available
Getting the same hash rate and temp on my 7970 at 1170MHz.
Getting an instant crash if I try with the older skein.cl with the new executable miner.
Exactly which version of skein.cl is exchangeable with which miner version?
Thanks for the updates and excellent work!!!
Thanks, tried todays version with both the new and old amdocl.dll version, instant crash on both and both included amdocl.dll in the error report.
Used the skein.cl that is 20358 bytes large on the latest 13.12 driver on Win 7 64 bit.
Tweaked the -f -w settings last week already, the same are valid for the new version.
Thanks for the quick update and response!
Post you SKC address for donations, in the signature.
Re: [ANN] [SKC] Skeincoin | Skein-SHA2 | CPU mining | GPU miner available
New miner doe seem to have lowered the temp a bit but... I have lost probably .5% to 1% hashrate at max settings...
Clocking my 7950 at 1200 and 1800 with +20 nets just under 190MH/s. Previously it was steady at 197MH/s or better with the python implementation.
BUT... I would gladly trade that for NOT HAVING TO MANUALLY RENAME AND CHANGE AMDOCL.DLL EVERY TIME I WANT TO MINE SKC!!!!!!!!!
In other words... this worked perfectly on Win 7 64 GCN drivers. Boom goes da dynamite!
You can simply replace skein.cl file with the one from previous version if it works for you better. As I am not sure what exactly slows it down on GCN (and if it depends on Catalyst version and how exactly if it does), I would rather not implement any dynamic code selection for specific cards in the miner itself.Clocking my 7950 at 1200 and 1800 with +20 nets just under 190MH/s.

Re: [ANN][BLC] Blakecoin Fast Blake-256 Cryptographic Coin for CPU/GPU/FPGA
Solo-mined for 3 hours with 3 graphics cards, got less than I would have gotten at the pool, even though the diff is much lower.
Huge spread in blocks, fastest was 5 minutes, slowest almost 2 hours.
After 3 hours I got 2 orphan blocks, used cgminer 3.1x on Win7 64 and latest wallet.
Just hate solomining...
Time to mine something else, that works...

Re: [ANN] [SKC] Skeincoin | Skein-SHA2 | CPU mining | GPU miner available
Thanks for the numbers.
Looks like all your cards are also mining about 3x slower than SHA256 coins running on cgminer.
Not sure what is needed to get that 3x speedboost, cgminer has a lot of functions/tricks to be that fast...
This isn't a pure sha256 coin, comparing it to sha256 cgminer performance is moot, esp in the face of missing optimizations between the two, i'm not the first too point this out. However r9 280x overclocked to 1100mhz 207MH/sLooks like all your cards are also mining about 3x slower than SHA256 coins running on cgminer.
Not sure what is needed to get that 3x speedboost, cgminer has a lot of functions/tricks to be that fast...
Lets compare Skeincoin with Blakecoin instead, running on AMD 7970/R9 280x at 1170MHz core and 300MHz mem:
Skein (poclbm-skc): 225MH/s
Blake (cgminer): 2800MH/s
SHA256 (cgminer): 700MH/s
Scrypt (cgminer): 700 KH/s (1050/1500MHz)
Moot or not, benchmarking is fun.
Re: [ANN] [SKC] Skeincoin | Skein-SHA2 | CPU mining | GPU miner available
Yes I can do that on my own... was not what I requested though.
Still looking... what modifications can be made to the existing scripts so that this can be forced to call amdoclskc.dll?
1K SKC still up for grabs.

Reorder had a better suggestion:
"I suggest that somebody steps in and replaces my quickhack dll with pure python implementation from http://pythonhosted.org/pyskein/"
Maybe better to offer the 1k bounty for a proper miner upgrade instead of another dll hack.
Re: [ANN] [SKC] Skeincoin | Skein-SHA2 | CPU mining | GPU miner available
Are you sure its optimized? I cant compare the gpu performance but when it comes to cpu, poclbm-skc hashes around 50% slower than skeincoin-cpuminer on the same cpu. I dont have much time right now, but I can compare it tomorrow.
Maybe we can create some kind of a benchmark to see the performance of particular gpus?
In my case its:
7950 - 180MH/s
r9 280x 200MH/s
Overclocking can get you another 5-10MH/s

5870 at stock core (850MHz) - 95MH/s
7870 (Tahiti) at 880MHz - 94MH/s
6950 at 900MHz - 103MH/s
6930 at 860MHz - 93MHz
Basically all cards giving around 90-105 MHz on my setup, overclocking doesn't change it a lot. On scrypt 5870,7870,6930 have performance close to 400KHz, and 6950 runs at about 450KHz, so current Skein-SHA2 implementation has 230-280 times higher hashrate than scrypt.

Re: [ANN] [SKC] Skeincoin | Skein-SHA2 | CPU mining | GPU miner available
No dice on the above... not a valid win32 application.
Dug into the Windows error report and it seems to be something with the amdocl.dll
EDIT: Found out why.
For Win 7 64 you do not use the system32 folder... you need to rename amdocl.dll in the SYSWOW64 folder and then add the one linked here.
Working now... time to tweak!
EDIT2: Of course... this has now broken my cgminer for scrypt mining unless I swap the files back... NICE!
yeah figured as much, march=nocona is core generation intel, I didn't have a dll issue at all and can switch between the two easly, must be a driver/sdk issueDug into the Windows error report and it seems to be something with the amdocl.dll

using driver 13-12_win7_win8_64_dd_ccc_whql, AMD-APP-SDK-v2.9-Windows-641 and cgminer 3.7.1 on r9 280x, win7 64 basic.
Well I am all set now... 193MH/s on my 7950 and got it running on the APU Devastator core on my 6800K... another 30MH/s.
Question if someone knows... what edits can be made to make this run and look for a DIFFERENT named amdocl.dll? I would like to make it call something like amdoclskc.dll and rename the custom amdocl64.dll made for this so I can put my reg one back and not have to file swap just to go back to scrypt mining.
1K SKC to the first functioning answer.
The fastest would be to create 2 bat files that does the renameing for you.
First one for SKC, to rename the original amdocl.dll to amdocl.new and the "new" amdocl64.dll to amdocl.dll.
Second one to reset the names above.
Good luck!

Re: [ANN] [SKC] Skeincoin | Skein-SHA2 | CPU mining | GPU miner available
sleinhash.so is only used in other threads than the one that runs the kernel (does actual solutions search), so no, 64bit will not yield more performance. Skeinhash functions can even be rewritten in pure Python without losing any performance.
Thanks for the info and the miner!
Then there is no reason for the miner to be 3x slower, other than being based on "older" poclbm core with less ATI optimizations?
It is missing the
VECTORS BFI_INT FASTLOOP AGGRESSION
functions that I guess speed things up more for bitcoin in cgminer?
Running at 220Mh/s on a 7970@1170MHz, which runs at 700+ for SHA256 coins.
Only one guy runs anything faster (Anonymous) at the pool, which may be 2 cards, still halfway from 600+ per card.
Re: [ANN] [SKC] Skeincoin | Skein-SHA2 | CPU mining | GPU miner available
I also noticed skein doesnt need high memory frequency so you can decrease it almost all the way down without any performance hit. Skein miner is probably not optimized yet and thats why it needs less power i guess.
The kernel does not use VRAM at all (save for tiny bit to pass back results to miner), so yes, you can downclock it to minimum. It is optimized, though, but for GCN. Chances are that if you replace rolhack functions with rotates, arrays with variables and unroll skein rounds, it will perform better on VLIW architectures.To confirm the facts above:
Running at 300Mhz memory frequency, same speed as 700 or 1200Mhz on a AMD 7970.
(Same as any SHA256 coin).
Others have measures >100W power savings at 300MHz compared to 1500MHz. Anyone care to confirm?
Miner is running about 3x slower than cgminer on bitcoin, on my 32 bit Python installation.
Any idea if a 64bit Python compile will boost the hashrate? (As skein is supposed to be faster at 64bit)
Tested -w 256/128 and -f 1/5/10/30 with no major speed gains on an AMD 7970.
