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

[nerdralph]

I think the silentarmy improvements we are seeing are an example of open source development working well.  I've known for several days that the the atomic_inc in ht_store was a speed bottleneck.  I thought if all the counters were in their own table, it could improve L2 cache hit rate.  The table would be 4MB, which is still large compared to a 512KB L2 cache.  In my discussions with eXtremal, he had an idea for using a single uint for multiple counters by using atomic_add instead of atomic_inc.  The two ideas together (and eXtremal's fast coding) made the latest optimizations.

If we were both working on closed-source miners, these improvements would've taken much longer, or may not have happened at all.

I released a binary for those that are having a hard time merging/building.  Ubuntu 14.04/fglrx.
https://github.com/nerdralph/sa-nr/tree/master/releases

Submitted a pull request as well so it's ready to go.

Two heads are better than one, the open source ...That's why I switched from windows to linux ubuntu for 8 years til now not only for mining but for my daily life... even if you are not an active coder like me but you have decent knowledge in programing you can help and give a hand to the community

[nerdralph]

Another optimization idea I have is to improve the early removal of duplicates.  With the current code there are hundreds of collisions on the last 40 bits, when only an average of 2 of them are valid solutions.  The code does rudimentary duplicate pruning at each round by removing the (average of 2) collisions that zero on the next 20 bits.  Nothing is done to remove duplicates across multiple rounds.  For example on round 1 we could have the following collisions:
ab ac bc de fg
on round 2 we could have:
abde abfg
and then on round 3 we could have:
abdeabfg

But since 'a' is duplicated it is not valid.  Rather than waiting until the final round, I think dups from round n-2 could be pruned in addition to the basic n-1 pruning.  This could be done by storing a compressed index of the round n-2 indices.  With the count now in it's own table, that frees up the 32-bit counter space in each slot.  By removing padding from the slot data format, it would even be possible to store uncompressed indices.  I think the best solution would be to combine the compressed indexes with expand_refs when there is a near duplication on round n-2 indices.  16 bits can represent a group of 16 of the million (2^20) rows, so for 65535 out of every 65536 times we would know there is no duplicate on the n-2 indices.  For the 0.0015% of the time that there is a possible duplicate, expand_refs is run, and the collision is pruned if there are any dups.

Well if you are a good coder then you know most of the time two heads are not better than one.  It's only for complex problems that there is a multiplication effect.  For simple code where the optimal solution is already known, I'd use another old cliché: too many cooks spoil the broth.

Hi,

I'm  trying to get it running on a rented server with nvidia / cuda interface.

Compile worked and the Card ist detected fine:

Anyone got a clue what's wrong here ?

Can anyone put together a binary on linux / windows for nvidia with the latest enhancements and cpu load fix?

[zawawa]

I was also wondering if anyone is currently working on a Windows binary.
I was to build one for myself, but I just don't want to duplicate somebody else's work...

Please go ahead and build please. Wasn't able so far to get it compile fully.

I think I am ready to go back to linux rigs. Can I ask someone to add a simple feature to the python code?

I wish to port my open source cross-platform web based miner monitor for silentarmy. An example of it I already posted above:


It was written for Claymore's miner but currently supports only single request:

Code:

{"id":0,"jsonrpc":"2.0","method":"miner_getstat1"}

and expects some stats back (miner version, uptime in seconds, sol/s per card and total, total/rejected shares and temp:fan - not for now).

It should wait for TCP connection on some port (3333). On connection it should receive an RPC request (that may or may not be CZM-compatible), return data and disconnect (as CZM does). Written properly, more RPCs could be supported (restart, pool change, etc).

Unfortunately, I never used python for real and everything I write will not be optimal. I could also write an external script to parse output, but it also will not be cross-platform. So if anyone can add a feature of JSON RPC to the miner, I'd be happy to port the monitor for it. It is written in javascript and runs under nodejs (Windows, Linux, MacOS - all work as a host).

KRNLX HAS GOOD NVIDIA CODE--

About 2 pages back, krnlx posted a package for nVidia linux miners.  Get it, extract the files, and change into the directory "silentarmy-nv".  When there, pull down eXTremal's 3 optimized mods.  They are posted a page or so back.  I simply used wget, and pasted each link, and the mods downloaded to the compile directory with the unmodded code.  Just execute "wget pasted.link", using the links posted by eXTremal.

Move the unmodded code into backups, i.e., "mv main.c main.c.old".  Copy the modded code to compilation code, i.e., "cp main.c.opt2  main.c".  Type "make".  and when the very short compile is done, you will have both "sa-solver" AND "libtime.so".  The "libtime.so" file produced by krnlx's code will allow nVidia cards to mine.  It is not produced by the main branch of mrb or nerdralph.

When done, you can mine with the "silentarmy" binary that is in krnlx's package.  The three eXTremal mods produce ~20% improvement in Sols/s on my GTX 960 cards.  They went from 18-20Sols/s to 24-25Sols/s.  These are stock 2GB EVGA GTX 960 SSC, and running at stock frequencies.

Similar steps taken with main branch code works on AMD cards.

I hope this is simple enough.       --scryptr

Alright, then. I really didn't want to deal with Cygwin again, but let's see what I can do...

updates for windows version? I have 2x 1070 who want a little more power,
at this time 60 h / s to 2 x 1070

TRY KOPIEMTU 3.0--

You can keep your Windows and boot to a USB stick.  The "rig-on-a-stick" boots and mines.  You may have noticed that currently SilentArmy is Linux only.       --scryptr

Any only cpu version available?
