● Raspberry Pi 3で GPGPU py-videocoreを動かしてみるテスト
Raspberry PiでGPGPU
nineties/py-videocore
● GPGPUとは？
GPGPU - Wikipedia
GPGPU（General-purpose computing on graphics processing units; GPUによる汎用計算）とは、GPUの演算資源を画像処理以外の目的に応用する技術のことである
● GPGPU py-videocoreのインストール方法
py-videocoreの Gitの公式手順通りに行なえば良いが Python 2系だと文字列処理の Unicodeでエラーが出る。
※ Python 2はもう時代遅れだから特に理由が無い限り使わない方が良いです。
# お決まりの sudo apt-get update
sudo apt-get update
# GPUの使用メモリを 128MBにする
sudo raspi-config nonint do_memory_split 128
# GPUのファームウェアをアップデートする
sudo rpi-update
# 再起動する
sudo reboot
● Python 2系に py-videocore GPGPUをインストール
# Python 2.7にインストール
# rpi-vcsmをビルドする
cd
git clone https://github.com/Idein/rpi-vcsm.git
cd /rpi-vcsm
pip install -r requirements.txt
# sudoを付ける
sudo python setup.py install
sudo pip install nose
Requirement already satisfied: nose in /usr/lib/python2.7/dist-packages
