ubuntu mpich cluster

음.. 구조를 일단 파악을 해봐야 하나..

odroid 쪽은 mpich2 패키지가 없네.. 버전이 달라서 그런가?

아무튼 mpiexec나 mpirun 나 둘다 똑같이 실행파일이 연결되네

호스트 파일은 아래와 같이 넣는데 얘도 winbind 적용 가능하려나?

설정방법을 대충보니...

빌드 돌릴 녀석이 host node가 되고, 얘가 nfs로 공유할 디렉토리를 생성해서 work node들이 여기를 연결

빌드에는 ssh를 key적용해서 암호없이도 할 수 있도록 해야 하는 듯..

옛날에 있던 녀석이니.. rlogin이나 telnet으로는 안되려나?
