[Dev] NeoScrypt GPU Miner - Public Beta Test

Alpha Wolf

Found a little time to play with the newest cgminer, here are my findings, tested with many different settings. -w 16 produced the best khash of all tested. 8 to 512

3.7.7b config 2x R9 270 non X did work up to -I 15 but OS became unresponsive with little to no gain in hash rate, -I 13 best hash and feel for system.

also running minerd 22 CPU cores Solo locked to 23 CPU cores, GPU locked to CPU core 0… 37kh/s per GPU or 75kh/s for the pair.

Thanks, I also have R9 270.

Will start with your settings ;)

Seems I’m getting a bit more rejects with 3.7.7b than I was with 3.7.5, still within tolerance I believe, was a max of 22kh/s per card with 3.7.5, so I like the gain in k.

Howto

Getting started with gpuminer

Linux: Get the program

download latest version from github here.

extract the zip file into an empty directory.

Linux: Compile the program (Detailed build FAQ coming soon)

change into that directory anr run ‘autogen.sh’

correct any errors that may be show. Typically some build tools may be missing.

run ‘make’ and optional ‘make install’ as root.

Run cgminer

run “cgminer --neoscrypt -o http://: -O :” *without the “quotes”

Is this part of guide still actuall?

I mean when I download this and version from 0.8.7.0 announce thread I get something totaly different.

tmuir12

That is the link to the latest 3.77b, so they should be the same.

the link from the announce thread is

https://github.com/vehre/neo-gpuminer/

The link you have above is just going one step further alone and linking to the zipped version

mirrax

Would be great to have step by step guide for complete idiots like me :)

Something like:

Anyone tryied with AMD Catalyst 14.6 Beta for Linux?

EDIT: with the help of tutorial from high on coins I managed to isntall catalyst (14.6) and card driver (just used different paths)

However when running autogen.sh I see the following bugs:

Any hint?

EDIT2:

sudo apt-get install libtool

sudo apt-get install curl

and

sudo apt-get install libcurl4-gnutls-dev

sudo apt-get install libudev-dev

fixed it

Hurray! I launched cgminer :)

Hmm not so sure what to do next.

There is plenty of readme files (even for scrypt or keccak) but Neoscrypt readme is more about Neoscrypt story than help with set up…

I am here:

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

mirrax

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

tmuir12

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 ._.

slowhash

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

slowhash

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
