cuda 독점이 깨지려나
아니면 범용 언어로 도약할까?

라즈베리의 config.txt는 uboot 와는 독립된 문법의 느낌이라면
odroid c2의 boot.ini 는 uboot의 환경설정 문법을 그대로 따라가는 느낌
그나저나 발열 문제 때문인가 클럭을 낮게 잡아놨네?

라즈베리 3 64bit 버전은 로그인도 느리고 (우분투 릴리즈라 그런건가..)
결정적으로 온도가 로그인시 60도가 찍히고 있다. 밤이라 25도 정도인데도
케이스 덮어두었다는 이유로 그 정도 찍히는거 보면 쿨러 없이는 작동 시키기 불안한 수준?
옆에있는 odroid c2도 비슷한 온도 느낌이라 발열이 적은 라즈베리 2나 라즈베리 1을 터미널 서버로
그 안에서 접속하게 하게 하고, 릴레이를 이용해서 전원 관리를 하는게 낫지 않나 생각이 든다.
