SILENTARMY v5: Zcash miner, 115 sol/s on R9 Nano, 70 sol/s on GTX 1070

[agis6]

Can u add values to your considerations ?
It would be even better
Thank you

Sure, here you go:

A. 1 x R9 380
Ubuntu 14.04.4 desktop, fglrx
Was 18-21 sol/s, now is 25-26 sol/s

B. 3 x R9 380X
Ubuntu 16.04.1 desktop, amdgpu-pro
Was 84-89 sol/s, now is 92-93 sol/s

C. 5 x RX470 + 1 x RX480
Ubuntu 16.04.1 server, amdgpu-pro
Was 135-147 sol/s, now is 145-148 sol/s

Setting OPTIM_SIMPLIFY_ROUND to 1 had the following results:
A. 29-31 sol/s
B. 92-97 sol/s
C. no change

Just wanted to ask about CPU model and usage. It seems that the performance highly depends on the CPU.

Running 470x2 on old single core gave me 7 per thread on 470.
Slightly better mobo + CPU gave 14/thread (28 per 470) - almost your result, see below.
Claymore's gives 45 Sol/s per 470 on Windows - on the 1st single core machine with 1GB of RAM (45 vs 14 Sols/s of this miner on the same mobo under Linux).

The results with single card and few cards on the same machine are also quite different. I use G3240 dual core CPUs on my rigs and it is not enough to run this at full speed.

So as for me, moving some filtering from CPU/bus into cards should be considered as a priority task if we want to outperform Claymore's miner. I've read that it is ALREADY faster. But trying on my cards (7950, 7970, 390, 390X, 470) - all with G3240 CPUs - I was not able to get the same results. Was close to with a single RX470 (Elpida RAM, 1500 straps, 2000 mem/1260 GPU - 46-47 Sol/s, Ubuntu 16.04 + amdgpu-pro 16.40) but without latest eXtremal patch.

So I do not understand how do you get a half of that only (148/6=25 Sol/s) on you rigs, but almost sure that the CPU usage is the reason. Have no other ideas.

I was getting over 30 on v3 using tighter memory timings and a 980/1550 clock.

Still have to merge/build v4 to test it.

[nerdralph]

Just tested out v4 on Ubuntu/fglrx and a couple R9 380 cards.  No material change.
Reducing MAX_SOLS from 2000 to 500 reduces the amount of data xfer over the PCI-E bus, and gives me about a 3-5% speed improvement running sa-solver.
In my fork I have OPTIM_SIMPLIFY_ROUND turned on, and the MAX_SOLS reduced.

Watch out you are missing solutions if you reduce MAX_SOLS. It might be ok if it correspondingly reduces the Equihash runtime, but you have to look at how many solutions you lose on a good sample >1k, such as "./sa-solver --nonces 1000"

that good or bad, as I have just updated this miner.  

seems like its good.

v4 tested and running in ubuntu 16.04 with amd-gpu-pro 16.40! ... seems a bit more solutions per thread!

Good work @mrb!

[ioglnx]

Is there a Windows release or not?!
Genoil's link gives a source only ?

It is a Python script + exe.

1. Download as ZIP on https://github.com/Genoil/silentarmy/tree/windows and unzip
2. Install Python 3.5+ for Win x64: https://www.python.org/downloads/windows/ (allow installer add python to PATH)
3. Launch .bat file (don't edit  )

You last built solvers are causing hard freezes..sa_solver.exe crashes system on exit while the other is not doing anything just opens..and you can't close if you want to reboot system it locks the system and you need to power it off.
Something strange happens with the last build ..the build before was working fine.

FWIW, exact same silentarmy code running on the same machine on an R9 Nano, dual booting into 2 OSes:
* 33.2 sol/s with fglrx 2:15.201-0ubuntu0.14.04.1 on Ubuntu 14.04
* 47.4 sol/s with amdgpu-pro 16.40 on Ubuntu 16.04

So yeah, a +40% difference just by changing drivers... No wonder you found a way to rework the OpenCL code to get a +40% on fglrx, and it gets you only +4% on amdgpu-pro.

amdgpu-pro compiles the OpenCL code just really, really well on its own, with almost no needs for manual tweaks.

[ioglnx]

But also +4% is something it just shows that optimizations can still be in cooperated

[hacko.bg]

I have a few rigs with 8 x R7 265. Starts mining successfully, but in mining screen I see devX up to 6, meaning giving display of hashrate up to the 6-th card. Possible to make it 8 at least?

[eXtremal]

Need tests on R9 2xx/3xx cards with new drivers. May be this patch takes effect only on NVidia and old flgrx drivers.

[mrb]

Absolutely. I even care about +1%, so I'll incorporate the changes!

with 3 instances getting 240-250 s/s on 6 x 1070 (eXtremal's input.cl and my cpu load workaround)

Could you try with only one gpu? And 1,2,3,4 instances?

hmm.. I really don't know why my gpu0 card runs slower o_O

Maybe because Xorg is running on it ? On windows 10 with Claymore's miner and rx470 cards, I have same issue - card, connected to monitor, runs slower

Tried without Xorg(no overclock), gpu0 slower, don't know why. Cards overclocked by memory(+1000  = +500 on win), getting 41-42, no overclock 35-38. Shitty nvidia-setting can't run without X ;(
