* OpenCL

** Docker (Mac)
MacのDockerで動かすには、VirtualBoxの設定が必要
 % VBoxManage setextradata "boot2docker-vm" VBoxInternal/CPUM/SSE4.1 1
 % VBoxManage setextradata "boot2docker-vm" VBoxInternal/CPUM/SSE4.2 1

** Linux
ドライバ
 sudo sh NVIDIA-Linux-x86_64-340.96.run

CUDA Toolkit 5.5
ドライバも含まれてる気がする
https://developer.nvidia.com/cuda-toolkit-55-archive
 sudo dpkg -i cuda-repo-ubuntu1210_5.5-0_amd64.deb
 sudo apt-get update
 sudo apt-get install cuda

global_work_sizeを8にしたら動いた。16以上だと動かなかった

** Tips
長時間処理しすぎるとOSがドライバを自動で再起動するらしい
