NSGminer v0.9.2: The Fastest Feathercoin / NeoScrypt GPU Miner

wrapper

I’ve finally switched over to NSGminer, R9 270, Linux 14.04 Catalyst 14.3

git clone https://github.com/ghostlander/nsgminer.git
cd nsgminer
./autogen.sh
make
sudo make install

I’m using this switch

–neoscrypt -g 1 -w 128 -I 13

I’d be interested if any one knows a better setting, however hash rate has gone up from 73 KHash/s to 183 KHash/s.

I tried some adjustments, so far…

-g2 - and that drops the Hash to 153 kHash/s

Thanks again for all your work, apart from being pleasing, the extra hash rate increases the security of FTC and other neoscrypt blockchains …

I’ve got my R9 290 up and running mining Neoscrypt .

Kubuntu 15.10, fglrx 15.20.3,

./nsgminer --thread-concurrency 22516 -g 1 --lookup-gap 2 -w 256 -I 13

~485 kHash/s

./nsgminer --thread-concurrency 40200 -g 1 --lookup-gap 2 -w 256 -I 13

~495 kHash/s

Note : if I included set commands, crashed the system, so didn’t use those with NSGminer.

set GPU_MAX_ALLOC_PERCENT=100
set GPU_USE_SYNC_OBJECTS=1
timeout 1

Note : Maximum Intensity with NSGminer is 13

@wrapper NSGminer ignores thread concurrency and lookup gap.

Hello guys,

I am trying to build nsgminer [ghostlander] with mingw32 on win 8 32bit and I have one problem which bother’s me

“configure: error: Could not find pthread library - please install libpthread”

I have installed this library and I have no idea what to do , i checked everything in google. If somebody has some idea, I would greatly appreciate it.

Thanks!

ghostlander

@jumparo Well, it certainly needs a threading library. It’s bundled with MinGW usually. You should be able to locate libpthread.a in c:\mingw\lib or something like. What version of the compiler do you use?

jumparo

@ghostlander I have this file in c:\mingw\lib. The compiler is “gcc version 3.4.4”. Have you tried to compile nsgminer with mingw32 or how have you compiled it on Windows?

ghostlander

@jumparo GCC v3.4.4 is very old. I build with v4.6.x, though anything newer should work as well.

jumparo

@ghostlander what OS did you use to build the windows binaries?
I tried to build it on Windows with mingw and msys2 but both failed in ‘make’ step because libdl is required and as far as i know this library is not ported in windows.

I’m now trying to build it on linux with mingw32. Can you tell me what did you pass to the configure script?
And do you use mingw32 ot mingw32-w64 toolchains?

ghostlander

@jumparo Windows XP 64-bit or 7 64-bit, doesn’t matter. Use configure from a Linux build. You only need to pass flags for Curl and Ncurses if configure fails on them.

jumparo

@ghostlander I successfully build it, but now I’m having “The application was unable to start correctly (0xc0000007b)” . Did you have the same error, and do you have solution for it ?

p.s I’ve tried already the most common solutions in Google and nothing helped.

ghostlander

@jumparo Either recompile with no NVIDIA support or start with --no-nvml or remove your nvml.dll library. It’s outdated probably and crashes the miner.

wec

Should I be running X in order to see the fan speed and temperature of my GPUs? I am running Ubuntu server LTS 14.04.X, AMD driver Crimson 15.12 for 14.04.X , and AMD app SDK 2.9.1. When I run in nsgminer -n. I get ADL initialisation error! Error – 21! Unable to load the Nvidia management library .

wec

This post is deleted!

ghostlander

@wec OpenCL doesn’t work without X on Linux anyway.

wec

@ghostlander

Well actually,the new drivers do. It depends upon to card. See excerpt title from installation guide below.

“Server GPU (Headless) and No-X Server Support with the AMD CatalystTM Graphics Driver”.

So running X allow the fan and temp information to be displayed via the miner interface?

ghostlander

@wec It does allow.

greenuser

what does it mean when the word “WAIT” appears after the fan and temp information?

@greenuser > What does it mean when the word “WAIT” appears after the fan and temp information?

It probably means you have disabled the GPU. Press [G] then look at the GPU status.

The menu options are there. The option [E] enables the GPU.

It can be easy to accidentally press D, after or whilst adjusting settings.

ghostlander

WAIT means a slow pool or an unreliable Internet connection.

@ghostlander - Do you have any knowledge of Ethos? Ive been using it to mine Ether for awhile and have recently tried installing your NSGminer on it to mine FTC. The miner loads ok and appears to connect to my pool and begin hashing but I never see anything on my pool. Ethos comes with sgminer-gm which can hash neoscrypt and setting that up works fine (both locally and on the pool) however its about half the speed of your miner.

Ethos is a slimmed down version of Ubuntu from what I understand, originally designed for Ethereum mining. Does your miner use something that may have been removed on Ethos?
