suprminer Quick Start Guide
Version: 1.3.34 (12/11/25)
Supported Algorithms: Neptune (NPT/XNT) and Xelis (XEL)
by ocminer (admin@suprnova.cc)

suprminer is a miner for CPU and NVIDIA on Linux, Hive OS and Windows. 

It's main design was initially for Neptune Cash (NPT) and later for XNT (Neptune Privacy) but since both of 
those coins have "mining pauses" when a new block template is generated, it was build with the initial
though that during thoses pauses it should switch to some other profitable coin and once mining is possible
again on NPT or XNT switch seamlessly back. This works as intented and pretty well but the miner can also
mine other coins without mining xel/npt at all.

Tests were made on different NVIDIA Cards, everything starting from the 30XX series up until 5090 works fine.
XNT has lower memory usage (about 12 GB) versus NPT which uses upto 28 GB VRAM (Video-RAM !). That alone
implies that only certain cards work with certain coins. CPU of course works everywhere but is rather
slow for NPT/XNT.

Xelis mining works with cards >= 6GB VRAM and was tested on CMP 170HX, 30xx, 40xx and 50xx series.

The miner has no fees on suprnova pools and 2% dev-fee on other pools.


System Requirements

OS: Linux (Ubuntu 22.04/24.04 recommended)
CUDA: 12.0 or newer (12.6+ recommended)
Driver: 525+ (550+ recommended for Blackwell)

CPU Mining (Background)
The miner can run Xelis on CPU in the background while GPU mines another algorithm.

Supported: x86_64 with AVX2 (Intel Haswell+, AMD Zen+)
Optimized for: AVX2 + FMA (most modern CPUs)
SIMD: Automatic detection and optimization



Usage:
======

Single Algorithm Mining
=======================

Neptune Cash  (NPT)
suprminer-neptune \
    -a npt \
    -o npt.suprnova.cc:3933 \
    -u username.worker \
    -p x
    
Neptune Privacy (XNT)
suprminer-neptune \
    -a xnt \
    -o xnt.suprnova.cc:3833 \
    -u username.worker \
    -p x
    
Xelis (XEL)
suprminer-neptune \
    -a xelis \
    -o xelis.suprnova.cc:3333 \
    -u wallet_address_OR_username \
    -p x




Dual Algorithm Mining (GPU + CPU)
=================================

Mine one algorithm on GPU while CPU mines another in the background.
GPU: Neptune XNT + CPU: Xelis
suprminer-neptune \
    --gpu-pool xnt.suprnova.cc:3833 \
    --gpu-user username.worker \
    --gpu-algo xnt \
    --cpu-pool xel.suprnova.cc:3333 \
    --cpu-user wallet_address_OR_username \
    --cpu-algo xelis \
    --cpu-threads 8
    
GPU: Xelis + CPU: Xelis (different pools)
suprminer-neptune \
    --gpu-pool xel.suprnova.cc:3333 \
    --gpu-user wallet1 \
    --gpu-algo xelis \
    --cpu-pool xel.suprnova.cc:3333 \
    --cpu-user wallet2 \
    --cpu-algo xelis \
    --cpu-threads 16
    
GPU: Neptune NPT + CPU: Xelis
suprminer-neptune \
    --gpu-pool npt.suprnova.cc:3933 \
    --gpu-user npt_user.worker \
    --gpu-algo npt \
    --cpu-pool xel.suprnova.cc:3333 \
    --cpu-user xelis_wallet \
    --cpu-algo xelis



GPU Fallback (Auto-Switch)
==========================

When the primary GPU pool has no work (e.g., block found, node syncing), automatically switch to a fallback algorithm:
Primary: Neptune XNT, Fallback: Xelis
suprminer-neptune \
    --gpu-pool xnt.suprnova.cc:3833 \
    --gpu-user username.worker \
    --gpu-algo xnt \
    --gpu-fallback-pool xel.suprnova.cc:3333 \
    --gpu-fallback-user xelis_wallet \
    --gpu-fallback-algo xelis
    
When XNT pool sends "no work available", the miner automatically switches to mining Xelis until XNT work resumes.



Multi-GPU Selection
===================

By default, the miner uses all available GPUs. To select specific GPUs:
bash# Use only GPU 0
suprminer-neptune -a xelis -o pool:3333 -u user -p x -d 0

# Use GPUs 0 and 2
suprminer-neptune -a xelis -o pool:3333 -u user -p x -d 0,2

# Use GPUs 1, 2, 3
suprminer-neptune -a xelis -o pool:3333 -u user -p x -d 1,2,3


Intensity / Batch Size
======================

Adjust mining intensity (affects VRAM usage and hashrate):
Set intensity (18-28, higher = more VRAM, potentially higher hashrate)
uprminer-neptune -a xelis -o pool:3333 -u user -p x -i 24

# Or set batch size directly
suprminer-neptune -a xelis -o pool:3333 -u user -p x --batch-size 5000000
Recommended intensity by GPU VRAM:

8 GB: -i 22
12 GB: -i 23
16 GB: -i 24
24 GB: -i 25
32 GB+: -i 26


# CPU-only mining (no GPU)
==========================
suprminer-neptune -a xelis -o xel.suprnova.cc:3333 -u user -p x --no-gpu

# GPU-only mining (no background CPU mining)
============================================
suprminer-neptune -a xelis -o xel.suprnova.cc:3333 -u user -p x --no-cpu


Troubleshooting
===============

"No work available" message

This is normal when pool mining XNT or NPT is processing a new block
Miner will automatically resume when work is available
Consider setting up a fallback pool


Out of memory

Reduce intensity: -i 22
Or use --xelis-batch-size for Xelis-specific tuning


Connection issues

Check firewall settings
Verify pool address and port
