[Dev] NeoScrypt GPU Miner - Public Beta Test

cisahasa

im not linux user but i think u should use sudo apt-get install libcurl4-openssl-dev libncurses5-dev pkg-config libtool , who knows better tells

no linux guide and fork is soon!

someone help these linux people soon!

Is the NeoScrypt kernal .cl file in the folder you are making from?

Sorry Gentlemen,

but it seems that opencl libraries and ncurses are not found by the configure script.

I never tried to compile cgminer with AMD drivers 14.X but I think this is not really a Neoscrypt related problem and the same problem may occur with any software you try to build on the system.

My suggestions:

check that ncurses and opencl are installed.
try the —dir or --lib option. and point it to the directories where opencl/curser are

./configure --help gives hints how to use it

Thanks for suggestions. Will try and provide feedback if it heped ;)

I thought that AMD drivers 14.x had issues working with cgminer and you shouldn’t go higher than 13.12

Can anyone tell me their optimum settings for R9-290?

I keep getting ‘Share is above target’

getting about 53Kh/s but 30-40% rejected. I have tried adjusting intensity etc but still seem to get the above no matter what i try. I am using 3.7.7b and AMD 13.12 Windows 7 x64

Cheers

HD6670 seems to have just 1Khs… what ._.

I’m also looking for optimum settings for the 290/290x gpu’s. (maybe a google doc spreadsheet with settings can be developed sort of like the litecoin one?)

Anyway, I’m currently running -I 14 -g 4 -w 32, and have one 290 GPU running 60 kh/s and an identical GPU running 51 kh/s. win7x64, ATI 13.25, 3.7.7b.

Tried another setting shown in this thread

-I 13 -g 3 --thread-concurrency 11264 -w 48 -s 15 -Q 3 -E 60 --auto-gpu --gpu-powertune 20 --gpu-engine 900-1000,1050 --gpu-memdiff 325,300 --temp-target 80,95 --temp-overheat 90,105 --temp-cutoff 95,115

but the 3.7.7b doesnt like the concurrency, and without it, only managed about 45 kh/s.

Im looking for a working config :\ my GPU (HD6670) gets outmined by just 1core of my core2Quad Q6600

Definitely need to adjust settings… Where are you starting at?

If your card is older than HD7000 series, don’t bother now. The kernel isn’t vectorised properly for the older cards. I have explained it on the previous page.

@mirrax

You are missing OpenCL libraries. If you have them installed correctly - it will say OpenCL found and then follow the rest of the instructions.

I found these instructions somewhere and fine-tuned them.

Try this - version numbers may have changed.

1) AMD app sdk:

http://developer.amd.com/tools-and-sdks/opencl-zone/amd-accelerated-parallel-processing-app-sdk/

cd ~/Downloads/
mkdir amd_sdk
mv AMD-APP-SDK-v2.9-lnx64.tgz amd_sdk
cd amd_sdk
tar zxvf AMD-APP-SDK-v2.9-lnx64.tgz
sudo ./Install-AMD-APP.sh

The installer for the APP_SDK seems to break some files, or at least it did during testing. Do the following to fix it:

cd /etc/OpenCL/vendors/

in here are two files amdocl32.icd and amdocl64.icd, you will find their contents (they are just text files) to be “libamdocl32.so” and “libamdocl64.so” respectively.

Edit them to include their full paths, so the contents of

amdocl32.icd --> “/usr/lib32/fglrx/libamdocl32.so”

amdocl64.icd --> “/usr/lib/fglrx/libamdocl64.so”.

NOTE: A user building on Xubuntu 13.10 reported his libamdocl32.so and libamdocl64.so libraries being at /usr/lib/i386-linux-gnu/libamdocl32.so and /usr/lib/libamdocl64.so respectively.

2) ADL SDK

http://developer.amd.com/tools-and-sdks/graphics-development/display-library-adl-sdk/

In this example, my source code is in ~/Miners/cgminer

cd ~/Downloads/
mkdir adl
mv ADL_SDK_6.0.zip adl
cd adl
unzip ADL_SDK_6.0.zip
cd include
cp * ~/Miners/cgminer/ADL_SDK

@slowhash

I read somewhere that thread-concurrency has no bearing in neo-scrypt

I have compiled 3.7.7b under Ubuntu.

I have not managed to get it to run for more than 24 hours at a time.

Lots of restarts between accepts - i am running this against a p2p pool for PXC.

I have had the same problem with all versions not running very long I’ve tried all suggestions but it still quits. Only thing that works for me is start it with the -T option and it runs and runs…

Hi everyone! First real post here. Long time lurker, but finally got around to creating account due to NeoScrypt. So far I am very excited and think this is a great move. I do have some questions though.

Does anyone know if the current settings for solo mining are going to be the same once we fork? If my understanding is correct, we just need to have neoscrypt cgminer running when feathercoin forks and we should be good, right?

tmuir12

You can solo mine with the neoscrypt cgminer, but I’ve found that you will need different setting to what you use for Scrypt mining.

The easiest way to try it out now is to set yourself up to attempt solo mining on Phoenix coin to work out your optimum settings and then you just need to change your solo miner setup to point back from the PXC wallet to your Feathercoin one.

Imperialcoin (IPC) is making the switch to neoscrypt in 450 blocks.

Difficulty will be way lower than Phoenixcoin. Maybe use that one for solo mining testing.

My batch files

for p2pool mining : cgminer.exe --neoscrypt -I 14 -w 48 -g 2 -o stratum+tcp://prometheus.phoenixcoin.org:10554 -u -p x

gives 90 kh/s on amd 280x

for local mining : cgminer.exe --neoscrypt -I 13 -w 32 -g 2 -o 127.0.0.1:9554 -u -p

gives about 80 on the wallet
