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

[agis6]

Have anyone try this miner https://github.com/Optiminer/OptiminerZcash ?

yup...faster than SAv5. But I'm sure SA will catch up soon

Edit: maybe not as stable, just had a crash.

Tongas work great (R9 380 -> 84 sol/s)
Ellesmeres crash after a while

Any hint why the solver ist 2 times SLOWER in V5 compared to V4 ?

Regards

Try running with ./silentarmy --instances=1 option, it is faster on my nvidia cards with one instance

And replace main.c with this, then rebuild

Sorry no same with the changed main.c :

The difference is in the solver ..

regards

Anyone got an idea what's the cause of the speed decrease with V5 ?

./silentarmy --list
Devices on platform "NVIDIA CUDA":
  ID 0: GRID K520

regards

2 GK104 GPUs it's Kepler also...wont get much with it...

I know it's not much - but I got ~ 15 wit V4 and only 50% with V5 .
or can't the miner be optinized for this chip ?
regards

Yes it's faster, with 3 Rx 480 I've got from ~265 sol/s with silentarmy to 310 - 365 sol/s with this. But it crashed on GPU #0 after ~10 minutes and only a reset helped with it, so my vote is on silentarmy! You are doing great guys!

 I had a rig crash and now it crashes each time I start optiminer. The rig just restarts. As I said previously, not stable or it asks too much to my cards...don't now

[EuroCanuck]

just tried all versions of the windows port.. weird problem with 2 rigs... 1 rig is 6 RX 470's and it will only do 20sol/s on each card but when i installed on another rig thats exactly the same(OS/drivers/hardware) they do 76sol each... same with another set of rigs that are 290/290x mixed ...1 works awsome,1 very slow 23ish sols.. cant figure out what the difference is that is causing it..

Download cigwin 64bit when asked for packets search python3 interpreter install and run from start.bat included in zip file(don't forget to edit...or not

[BitcoinGeekBoy]

Is it better to do --instances=2 or --instances=1?

What are people running with for this switch that gives the best results?

[krnlx]

Latest version gives me 92-93 sol/s from modded RX480:

one question about this code

Code:

 __local uchar	*first_words = &first_words_data[(NR_SLOTS+2)*tlid];

It is shared memory, and NR_SLOTS=12, so NR_SLOTS+2=14 bytes, and it is not aligned by 4 byte memory bank size... I tryed to fix it(make +2 bytes offset, seems getting another 1-2%, but difficult to confirm it.

And changing

Code:

#define COLL_DATA_SIZE_PER_TH		(NR_SLOTS * 5)

to

Code:

#define COLL_DATA_SIZE_PER_TH		(NR_SLOTS * 7)

gives +5% on 1070(confirmed).

[sp_]

I get 70sol/s on the 1070 with the latest SA kernel windows port

But zcash is currently being harvested by kernels that produce 200% more

running latest version 5 on win

all gpu are 470 4gb sapphire nitros EXCEPT dev 2 with elpida memory.

was running on 1st version it's fine but after upgraded to latest only dev 2 with elpida memory acting up...

any help ?

TIA

All default, no changes

It is shared memory, and NR_SLOTS=12, so NR_SLOTS+2=14 bytes, and it is not aligned by 4 byte memory bank size... I tryed to fix it(make +2 bytes offset, seems getting another 1-2%, but difficult to confirm it.

I see no difference.
Edit: NVidia no difference, but AMD RX480 faster by 1-1,5% when remove "+2".

gives +5% on 1070(confirmed).

You are right for GTX1070, went from 70 to 73 sols/s

I didn't remove +2, added another +2

[beeboop]

 new to this. how do you upload an image saved on ubuntu?

[eXtremal]

I didn't remove +2, added another +2

+2 not need anymore for all platforms.
COLL_DATA_SIZE_PER_TH best *5 for AMD and *6 (or *7) for NV Pascal.

You mean a picture? Save it in any online service, like imgur (http://imgur.com/)

Then, insert the link to it here.

Got it?
