GPU miner for the Pearl (PRL) network. Mines via AlphaPool's stratum endpoint.
Binary distribution by permission of the author. Source remains private.
NVIDIA only. CUDA driver 545+ required.
| Architecture | Generation | Examples |
|---|---|---|
| Volta (sm_70) | data-center | V100, CMP 100-210, CMP 90HX |
| Ampere (sm_86) | RTX 30-series, A-series | 3060 Ti, 3070, 3080, 3090, A4000 |
| Ada (sm_89) | RTX 40-series | 4070, 4080, 4080 SUPER, 4090 |
| Blackwell (sm_120) | RTX 50-series | 5060 Ti, 5070, 5070 Ti, 5080, 5090 |
| Hopper (sm_90) | data-center | H100, H200 |
The miner auto-detects GPU architecture. Override with --force-backend if needed.

Vardiff takes 5–7 min to ratchet to the right value on high-end cards. For consistent share submission, pin difficulty in the password field:
./alpha-miner --pool 15.204.220.54:5566 --address PRL1... --worker myrig \
--password 'x;d=65536'Recommended starting values:
| GPU class | d= |
|---|---|
| 3060 Ti / 3070 | 16384 |
| 3080 / 3090 / 4070 | 32768 |
| 4080 / 4090 / 5080 | 65536 |
| H100 / multi-GPU rig | 131072+ |
Single GPU, default PPLNS settings:
| GPU | TH/s |
|---|---|
| RTX 3060 Ti | 40–50 |
| RTX 3070 | 50–60 |
| RTX 3090 | ~90 |
| RTX 4090 | 150–160 |
| RTX 5080 | ~105 |
| CMP 100-210 (Volta) | ~70 |
One process drives all GPUs by default. To pin to specific cards:
./alpha-miner --pool 15.204.220.54:5566 --address PRL1... \
--worker rig1 --devices 0,1,2,3For per-GPU worker naming on the pool, run one process per GPU and give each a unique --worker suffix.

libcuda.so.1: cannot open shared object file
NVIDIA driver not installed or driver version too old. Install/upgrade to driver 545+.
no kernel image is available for execution on the device
GPU architecture not supported by this binary build. Try --force-backend volta if you're on V100/CMP series.
Vardiff stuck low
Set static difficulty: add --password 'x;d=32768' (or higher for fast GPUs). See the table above.
Shares rejected stale: chain advanced
Normal — pool moved to a new block; your in-flight work doesn't count. <1% rejection rate is healthy.
