1 gpu. After running for 5 seconds - 1 minute falls 1 of 2 sa-solver.
I noticed that falls if there is memory overclocking frequency (even minimal).

Sorry to write such thing about this great miner, but I try to compile new version #4 and it gives me only 4sols a card while #3 gives me 30..
I do not know why..

A lot of miners have 5+ GPU and 6+ GPU AM3 boards (970, 990) chipset boards. They use Semprons and Althons for these boards.

Using multithreading on 5+ GPU rigs, the system load spikes to over 5, and in some cases to over 10. This results in reduced hashrate on GPUs (in some cases, hashrate is reduced by 50%). It may be a good idea to optimize the stratum connections that are managed by CPU, or fix whatever is causing the high CPU load.

Would you know if there's an AMD driver package I could use for 2x FirePro D700 on a mac for use with this project? I searched around the AMD site, although since that's a specialized card there don't seem to be any drivers available, thanks!

Just updated to current master and started getting this on nicehash: Stratum: SILENTARMY is not compatible with servers fixing the first 17 bytes of the nonce

Not sure if legit error or not

Many people run mixed GPU rigs of 2gb cards and 4gb cards. Please add feature to define instances like:

--instances 1,2,2,1

This will allow users to define instances on a per-gpu basis. Right now, the only work around is to run separate miner instances with different flags.

Thank you!

Hi, I just did a checkout of v3 and compiled it.
I have this error when i launch my fresh compiled silentarmy (the bundled binary works fine though)

Hi.

I want to run silentarmy in a remote computer which I have ssh access.

The problem is if I run ./silentarmy or sa-solver with --list or any other parameter, it seems to be waiting for something that never arrives and I have to kill the process or just press Ctrl+C.
This only happens when I'm running the command remotely.

On the other hand, if I don't run the command remotely, that is, by going physically to the computer , logging in through a graphical session and then opening a terminal in the desktop, the command works fine.

I have tried export DISPLAY=:0 too with no luck.

This might be design, but usage of ensure_future() (eg. https://github.com/mbevand/silentarmy/blob/master/silentarmy#L105 ) in silentarmy requires Python 3.4.4+ .

Trusty only has up to 3.4.3 available (http://packages.ubuntu.com/trusty-updates/python3.4)

Maybe deprecate support for 14.04 ?

Hello. I am running silentarmy on Ubuntu 14.04 with a Radeon 7970 using proprietary drivers.

When running $ make test it seems to run fine without any errors.

However, when running $ silentarmy --nonces 100, I end up with Total 0 solutions in 8429.2 ms (0.0 Sol/s).

6 gpus with 2 instances runs fine but the seventh didnt run over 2..... a bit annoying when considering zogminer can run over 14 instances..... ( silentarmy still more efficient with 13 but would be preferable with 14 :) )

If you follow the instructions for Ubuntu:

1. Fresh install of Ubuntu 16.04.1 (AMD_64 Desktop version)

2. Download and install latest AMDGPU-PRO Driver (16.40)

3. Add user to video group

On reboot, system will kernel panic every time.

Tested on multiple rigs.

sa-solver may continue to send work to a GPU that has produced continuous invalid work (indicative of crash).

This results in ASIC HANG HAPPENED and possible hard crash. It would be a good idea to check for invalid work and prevent sa-solver from continuing to send work to that GPU.

If user runs multithreaded solvers, prevent other threads from sending work as well.

Hi, using ubuntu 14.04 (4.8.0-rc6) + amd gpu pro 16.30 on 6-card-rig (stable on ethereum + claymore). I have 0.0 (zero) sols after few minutes of mining. Hardware is Asrock H97 anniversary + RX470 refs.

If stop and restart miner threads could not been initialized, so I need to reboot. I am using zec.nanopool.org

Here is dmesg output: http://pastebin.com/fg5ZEiai

It's not a standard package, so it has to be built from source or use a PPA like http://ppa.launchpad.net/chris-lea/libsodium/ubuntu/

I am getting the above error when starting the miner. Tried on different computers (both with ubuntu trusty) and both suprnova and flypool with the same results.

Below is the debug log.

After 1h of mining periodically there are messages "Pipe closed by peer" and then begins to decrease speed. In the end, one of the 2-card shows 0sol.

Hi,

After 753 line in main.c need add:

if ( (inputs[i] / 8) >= seen_len ) {
sols->valid[sol_i] = 0;
return 0;
}

Best Regards,
Warp.

Just started testing the miner. It seems like its doing a good job mining and 0% is rejected but it seems to be outputting roughly 10 of these in a minute:

Stratum server returned wrong id: XXX

I tried out couple pools (nicehash, coinmine) and happened on both of them. Rig consists of 6 AMD GPU's and Ubuntu 14.04 with Python3.5.

AFAICT its just noise

To compile your miner on cuda 8.0 I need to write the path and only then it compiles:

make OPENCL_HEADERS=/usr/local/cuda-8.0/targets/x86_64-linux/include/ LIBOPENCL=/usr/local/cuda-8.0/targets/x86_64-linux/lib

"sa_solver --nonces 100" exit with that error. Compiled on Debian 8.6.0 .

I extracted the Silentarmy master folder and ran the make command, but it did not provide the Sa solver file. Here is the cmd line error

Running Ubuntu 12.04LTS with Python 3.3, I get this error:

john@john-ubuntu:~/Desktop/silentarmy-4$ ./silentarmy --list
bash: ./silentarmy: /usr/bin/python3: bad interpreter: No such file or directory

clinfo returns my GPU info and sa-solver and make test both work fine. Any advice?

Good job with the miner; some suggestions I may add:

1. I see you set new job immediately after set_target is received; this is not correct, new target is used for every NEXT job that arrives, so you don't need to do anything but just save the new target.

2. You may simply ignore jobs that have clean flag set to false. Some pools regularly send out jobs with clean flag set to false. If you always swap to these new jobs, your mining performance is a little degraded (due to cancelled solution finding). It is completely safe to ignore clean=false jobs, because hashing is so slow process that the miner would never run out of nonce range (nonce range can be restarted with new job).

3. I suggest you to implement extranonce.subscribe. It is an extension of stratum that allows the pool to change server side nonce on miner during the work (and not only initially when subscribed). That way your miner would perform in the best possible way on our service as well (otherwise, miners get reconnected, which is not so good).

What you need to do is following; after you subscribe, send following msg: {"id":3,"method":"mining.extranonce.subscribe","params":[]}\n

When you receive following from server:
{"id":null,"method":"mining.set_extranonce","params":["xxxxxxxxxxxxxxx"]}\n

xxxxxxxxxxxxxxx represent new server side nonce. You continue to use this new server side nonce with NEXT mining job. Simple as that ;)

Thanks for making a linux GPU miner!

I'm trying to do this on debian.

Pretty much what it says on the title (please pardon if silly question)

I have suspicion that this is true. Cannot do much work about it, don't have AMD card. So, how is it in reality?

Had to take a GPU out of my rigs as I get an error starting the miner with 8 as I was doing with my previous zcash-miner. 7 GPU seems to be the limit

I have a weak machine so I mine with cpu+gpu. Would be nice to add xenoncat's cpu solver to your gpu miner because there is no better one around. Your gpu solver + xenoncat's cpu solver are the best!

Seems it's an issue between 64/32 bit compatibility. The first error seems a redefinition of ulong, that seems to be already defined in Raspbian.

Hi,

I believe this line:

is a bug. The problem is that the function would alternate the supplied header which is something not expected by the caller of the function. I am aware that so far this is not a public library. However, a simple case shows that even the sa-solver binary generates sort unexpected solutions. E.g.:
./sa-solver -i 040000000000000000000000000000000000000000000000000000000000000000000000db4d7a85b768123f1dff1d4c4cece70083b2d27e117b4ac2e31d087988a5eac4000000000000000000000000000000000000000000000000000000000000000090041358ffff071f5712000000000000000000000000000000000000000000000000000000000000

This is the header of the very first block from the main zcash chain. However, the solver would calculate solutions for nonce 0x13, not 0x12 (as specified in the header). The amount of CPU time needed to adjust the nonce field is very neglegible and I believe, the functionality to autoincrement it should be removed. Especially, when it's specified as part of the full 140 byte header.

Hi, I installed the newest nvidia drivers with the cuda 8.0 install on ubuntu 16.04 as in:
https://github.com/etherchain-org/nheqminer#linux-ubuntu-1404--1604-build-cuda_tromp

And built your miner and ziog miner with no errors but on both miners during the launch I get the same error.

./silentarmy

Maybe you can add support more easy when you see how nheqminer did it. Too bad that miner is a bit slow 2.5 sol on 740M, i hope your's is better. Thanks for your work.

Thanks for the updated miner. Looks simple and great.

Selecting one device works well.

Sometimes silentarmy starts on all gpus, and then drops one or more of them, showing 0.0sols on those cards.

I'm running silentarmy in screen, and when i kill it, sa-solver processes stay running, and nothing can kill them killall -9 sa-solver, or kill -9 {PID}

also, when this happens, I can't reboot rig, ssh disconnects but rig stays running.

Dear,
I'll do the os x port.
Changed compiler structs and opencl headers but get a bunch of errors. Any clue?

Hi, why the silentarmy raised exception?

Hey your stat python code has a bug...seems to be throwing key errors. The miner still works and hashes in the background, just stats no longer display:

Hello. Thank you for developing this great application. Multi-gpu support is awesome.

I am getting the following error, hope you can help me out.

Error from silentarmy:
pipe closed by peer or os.write(pipe, data) raised exception.

Error from solver:
Solver 2.1: unexpected banner "Maximum number of clients reached"
SILENTARMY mining mode ready"

My rig has 4 HD 7990 6GB, which supposedly are 8 cards of 3GB each.
I get this error when I use instances 2, and when I change it to 1 mining starts without problems.
But I guess these cards should work with instances 2 or am I wrong?

BTW, I have executed "./sa-solver --nonces 100" and it runs without problems on each card.

Ubuntu 15.04 with Crimson Driver 15.12

Hello. After install AMDGPU-PRO Driver I cant login in my machine UBUNTU 16.04, need password< my machine password no work.
Auto login no work.
What I can do .HOW FIX THIS ISSUE?

Got this issue with every linux miner, the first card is spinning at 1/3th or 1/4th of the rest, any idea on how to fix this?

after the installation, as soon I run ./silentarmy --nonces 100 i get the error:

Solving default all-zero 140-byte header
Cannot get OpenCL platforms! (-1001)

running make I get the error: /usr/lib/libOpenCL.so: until I have run sudo apt install ocl-icd-opencl-dev

thanks
