[ANN] Open Pearl Miner - open source miner for Pearlhash (Nvidia/AMD)

[Neilquick]

Open Pearl Miner (Nvidia/AMD)
A high-performance Pearl (PRL) proof-of-work miner for NVIDIA and AMD (beta) GPUs.

Mixed-GPU rigs are supported. Ampere/Ada cards run a fused int8 tensor-core kernel (GEMM + in-mainloop transcript fold + tensor-core noise generation), bit-exact with the Pascal DP4A path; Pascal cards run DP4A.

Features
AMD cards beta support
~7.0 TH/s sustained on a single Tesla P40 (Pascal DP4A).
~30 TH/s on a single RTX 4050 mobile (Ada) — fused int8 tensor-core GEMM + in-mainloop transcript fold + tensor-core noise generation, all bit-exact with DP4A.
~220 TH/s on RX 9900
Multi-GPU — auto-detects every GPU and runs one worker per card, near-linear scaling.
Continuous mining — no idle time waiting between pool jobs.
Background proof submission — finding a share never stalls the search.
Solo mining — mine to your local pearl-gateway node.
Pool mining — built for LuckyPool's Pearl stratum (default) with more pool protocols planned.
HiveOS — full HiveOS custom-miner package.

Available for Windows/Linux/Hive

Quick Start

Windows

Code:

p40-miner.exe --wallet prl1YOURWALLET --worker rig1

Linux

Code:

./p40-miner --wallet prl1YOURWALLET --worker rig1

That's it — it auto-detects all GPUs and starts mining.

HiveOS
Download p40-miner-1.7.1.tar.gz and install it as a Custom miner:

Code:

Flight Sheet → Miner = Custom.
Set the Installation URL to the tarball, or scp it to the rig and run tar -C /hive/miners/custom -xzf p40-miner-1.6.1.tar.gz.
Wallet and worker: your Pearl wallet prl1... (worker name auto-appended).
Pool URL: pearl-eu2.luckypool.io:3360 (default LuckyPool GPU pool).
Extra config arguments (optional): --devices 0,1, --region 4096, etc.

The miner reports per-GPU TH/s and accepted shares to the HiveOS dashboard. Built against glibc 2.31, so it runs on both the focal (20.04) and jammy (22.04) HiveOS images and newer.

Open Pearl Miner v1.8.0 public release

What new
Added support dual mining ModelOS and Pearl (MDL+PRL)
Fix error on 6700XT
Support 9700XT cards

What changes
Intel Arc XMX — Implements an 8×8×32 INT8 cooperative matrix fold shader using SIMD8. Produces a bit-exact transcript through per-lane XOR combined with subgroupXor across four 8×8 fragments that form a single 16×16 hash tile. Validated against CPU results.

RDNA1 / Vega 56 (SWINT8) — Uses a software-emulated INT8 dot product by manually sign-extending operands and performing INT32 multiply-add operations when shaderIntegerDotProduct is unavailable. Shares a unified execution path with the DP4A implementation.

Architecture gating — Updated to use the exact RDNA2 device ID range (0x73BF–0x7447), allowing RDNA4 devices (0x7550) to bypass the RDNA2-specific path correctly.

Vendor detection — vendor_id is captured during initialization; Intel's vendor ID (0x8086) enables acceptance of the XMX 8×8×K matrix shape during the cooperative matrix capability probe.
