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

[olcaytu2005]

can anyone help. mining with 1 1070 card i get ~70/s, but with 6x1070 only ~150?
my cmd line:
py silentarmy --use 0 -c stratum+tcp://cn1-zcash.flypool.org:3333 -u t1KmpFfV7iZyNefokBgbMUpSYyMZX2qm7cr.A1 --instances=1

6 cards
py silentarmy --use 0,1,2,3,4,5 -c stratum+tcp://cn1-zcash.flypool.org:3333 -u t1KmpFfV7iZyNefokBgbMUpSYyMZX2qm7cr.A1 --instances=1

Change the second command line --use to 1,2,3,4,5,6 if it doesnt work try 2,3,4,5,6,7

guys,

how can i control gpu fan speed?
my fan speed is very low. gpu gets hot.


thank you,

So windows support?

When I stop seeing this every other 5 posts, I'll start thinking I'm reading another thread...

zawawa made a port, look back through thread to find it, and instructions.

It's not native... You know, it's almost like there is a high demand for something and it's not being fulfilled.

Windows port works great here across all three of my rigs (3x RX480, 6x RX480 and 7x 290x).

Getting 10% more hash than Claymore V4.0 and using a good 15~20% less power.

Nice work, many thanks all those involved!

which version you using? SILENTARMY-v5-Cygwin64-r6.zip?

[diedo]

Is it normal to get 80+  sols with one orphan R9 290X?

Tried using the windows port by zawawa and this was the result
upload an image

I'm using windows 7 64bit ultimate and installed cygwin64 on to main C:\ drive with Python3: Py3K language interpreter selected.
Error was with default start.bat being run. I have 2 cards in the rig 1 RX470 and the other is an RX 480 with latest AMD drivers.

Anyone know what I did wrong?

Thanks for any help

same here. need help

I had same error, resolved by uninstall amd driver with DDU (display driver uninstaller) and reinstall 16.10.3 driver

bat file to Mining Rig Rentals pls.

[BenCodie]

startum server started to give duplicate share error frequently why???

startum server returned an error [22 duplicate share]

pls help

[joaocha]

bat file to Mining Rig Rentals pls.

There is no support for Mining Rig Rentals

this one doesn't need cygwin. still needs python of course. only works with instances=1 (default).

sorry for late release..flu-bound

SA5 has no more easy optimizations left; the current version maxes out the memory bandwidth of the card.

Does it also max out the PCI-E bus bandwidth? I'm trying to understand why my Nitro+ RX470 (at 75~80 Sol/s) is finding as many shares as my R9 295x2 (2 x 90 Sol/s)...  Any idea?

With the on-GPU solution pruning it barely uses any PCI-e bus bandwidth.  My comment about maxing out the memory bandwidth is a simplification of a complex problem.  The memory path includes L1 & L2 cache as well as the external GDDR5.  I believe parts of the current performance bottleneck are due to L1/L2 cache thrashing.  There's at least a couple ways of solving the problem, but none (that I can think of) are easy.

I was profiling it yesterday, the limiting factor right now is LDS. To optimize it, total memory accessed by the round kernel wave would have to be reduced. Currently it falls into about 16K. CodeXL says that utilization during rounds is 12.5% due to this. I can send you more data if you want or you can profile it yourself with CodeXL 2.2.

I don't use profilers.  Unless you really understand the code and underlying architecture, and how the profiler works, you can easily get mislead by a red herring.  Here's what I use:
AMD_OCL_BUILD_OPTIONS_APPEND=-save-temps
The AMD GCN architecture docs, and some tweaks are all I need to analyze performance.

The current bottleneck in ht_store could be avoided without using LDS, and I already discussed this with eXtremal.  It would involve a 16-way store operation where each thread stores 1 uint to 2 slots (even if only one slot is actually modified).  The 64-byte write would match the cache line and avoid L1/L2 cache thrashing.  See the GCN architecture doc:
"Cache lines are written back to the L2 when all 64 stores in a wavefront instruction have finished. Lines with all dirty data are also kept in the L1D, while any partially clean line is evicted from the L1D."

Where can i Finf a version of OptiminerZcash-master for windows?

I tryed to use the linux version with cygwin64, but did not work..

Am i dooing something wrong?

  File "optiminer-zcash", line 1
SyntaxError: Non-UTF-8 code starting with '\xdf' in file optiminer-zcash on line 2, but no encoding declared; see http://python.org/dev/peps/pep-0263/ for details

[krnlx]

Made a cuda port of actual Silentarmy 5

speeds sucks. 92 s/s on overclocked 1070(opencl version give near 100)

Tested only on linux.

If anyone want

Thanks a lot for your work, Genoil! I think some people feel more comfortable using your binary.
I am trying to remove the runtime Cygwin/Python dependencies entirely by compiling silentarmy.
We will see...

Thank you for stepping in! (btw it's still a py script and a solver.exe. not updating my own mining client until the updating dust dust settles a bit  )
