Module (PATH 편하게 잡기)

### Module (최신 3.2.10) 2016/3/22일 기준

http://modules.sourceforge.net/

### 공식 페이지 인듯

https://sourceforge.net/projects/modules/files/

### 소스포지 다운로드 하는곳

### RedHat 7은 CD mount 해서 yum으로 설치 가능

[root@node001 ~]# echo $MODULESHOME

/usr/share/Modules ### module home 경로 확인

[root@node001 ~] cd $MODULESHOME

[root@node001 Modules]# ls

bin  init  modulefiles

### init/.modulespath 파일에서 modulefile 불러오는 경로 지정함. 경로 추가만 하면됨.

### modulefiles/ 는 modulefile 있는곳. 다른곳 지정 가능함.

### 종류 별로 폴더를 만들어서 관리하면 편할듯.

[root@node001 init]# module av

---------------------------------- /usr/share/Modules/modulefiles ----------------------------------

dot         module-git  module-info modules     null        use.own

------------------------------------- /tmp/Modules/modulefiles -------------------------------------

compiler/gcc-4.8.2  mpi/intel-5.1.3     mpi/openmpi-1.10.2

compiler/icc-16.0.2 mpi/mvapich2-2.1

### 아래 내용은 compuiler와 mpi(mpich) 설정 사항 참고하면 됨.

### MPI 경우 compiler가 사전에 PATH가 잡혀있는지 확인하는 부분이 추가되어있음.
