Cuda conversion, authored by Belgarion

installation

• apt update
• apt install build-essential autoconf automake libssl-dev libcurl4-openssl-dev libjansson-dev zlib1g-dev screen git cuda-9-2 nvidia-396
• git clone https://github.com/belgarion/cuballoon
• cd cuballoon
• ./build.sh

Requirements

• Latest Nvidia drivers.

Tuning

Tune by modifying --cuda_threads and --cuda_blocks. Good starting points: GTX1060: --cuda_threads 64 --cuda_blocks 48 GTX1080: --cuda_threads 384 --cuda_blocks 48 GTX1080Ti: --cuda_threads 448 --cuda_blocks 48

Known bugs

• A few invalid shares when devfee kicks in.
• Sometimes not all GPUs are hashing (verify with taskmgr or nvidia-smi that they have compute utilization).

Other info

Devfee is around 3%.
