05 관리 및 accounting 명령어

(Administration and accounting commands)

• LSF administrators(관리자) 및 root 계정만 사용 가능

명령어	설명
lsadmin	- LSF administrator tool - controls the operation of the LIM and RES daemons in an LSF cluster - lsadmin help shows all subcommands
lsfinstall	- install.config 파일로 LSF 설치 - 문법: 경로/lsfinstall -f install.config
lsfstartup	- 로컬 클러스터 안에 포함된 모든 호스트들에 LSF 데몬들 시작
lsfrestart	- 로컬 클러스터 안에 포함된 모든 호스트들에 LSF 데몬들 재시작
lsfshutdown	- 로컬 클러스터 안에 포함된 모든 호스트들에 LSF 데몬들 종
badmin	- LSF administrative tool - controls the operation of the LSF batch system (sbatchd, mbatchd, hosts, and queues) - badmin help shows all subcommands
bconf	- changes LSF configuration in active memory

06 데몬 (Daemons)

데몬	설명
LIM	- 'Load Information Manager' - collects load and resource info about all server hosts in the cluster - provides host selection services to apps through LSLIB - maintains info on static system resources and dynamic load indexes
mbathd  (MBD)	- 'Management Batch Daemon' - accepts and holds all batch jobs - periodically checks load indexes on all server hosts by contacting the management host LIM
mbschd	- 'Management Batch Scheduler Daemon' - performs the scheduling functions of LSF - sends job scheduling decisions to MBD for dispatch - runs on the LSF management host
sbatchd (SBD)	- 'Server Batch Daemon' (previously 'Slave Batch Daemon') - accepts job execution requests from MBD - monitors the progress of jobs - controls job execution, enforces batch policies, reports job status to MBD, and starts MBD
PIM	- 'Process Information Manager' - monitors resources that are used by submitted jobs while they are running - PIM is used to enforce resource limits and load thresholds, and for fair share scheduling
RES	- 'Remote Execution Server' - accepts remote execution requests from all load-sharing applications - handles I/O on the remote host for load sharing processes
