curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

nvidia

# update-pciids
# lspci | grep -i nvidia

NVIDIA-Linux-x86_64-460.56.run

sh NVIDIA-Linux-x86_64-460.56.run

显卡驱动安装成功

# nvidia-smi

禁用nouveau

lsmod | grep nouveau

echo "blacklist nouveau" >> /etc/modprobe.d/blacklist.conf

update-initramfs -u

reboot

cuda

• 设置环境变量

vim .bashrc

# CUDA
export PATH=/usr/local/cuda-11.2/bin${PATH:+:${PATH}}
export LD_LIBRARY_PATH=/usr/local/cuda-11.2/lib64${LD_LIBRARY_PATH:+:${LD_LIBRARY_PATH}}
export CUDA_HOME=/usr/local/cuda

# vim .bashrc
# source .bashrc
# nvcc --version

• 设置时区和ulimit

timedatectl set-timezone Asia/Shanghai

echo "DefaultLimitNOFILE=1048576" >> /etc/systemd/user.conf

echo "DefaultLimitNOFILE=1048576" >> /etc/systemd/system.conf

vim /etc/security/limits.conf

* soft     nproc          1048576
* hard     nproc          1048576
* soft     nofile         1048576
* hard     nofile         1048576root soft     nproc          1048576
root hard     nproc          1048576
root soft     nofile         1048576
root hard     nofile         1048576

reboot

# ulimit -n
1048576

lotus

git clone https://github.com/filecoin-project/lotus.git

# cd lotus/
# git checkout v1.14.1
# git show
commit d2dca7b21718048e1a6dc15b90a44b3d298852fb (HEAD, tag: v1.14.1, origin/releases)

• 源码编译

env RUSTFLAGS="-C target-cpu=native -g" FFI_BUILD_FROM_SOURCE=1 make clean all lotus-shed

env RUSTFLAGS="-C target-cpu=native -g" FFI_BUILD_FROM_SOURCE=1 FFI_USE_CUDA=1 make clean all

• 取消IPFS_GATEWAYJD的网关默认使用官方的

unset IPFS_GATEWAY

32.09 GiB的文件需要更新 https://proofs.filecoin.io/ipfs/

lotus-shed fetch-params --proving-params 32GiB
