QUEUE_NAME = verilog
DESCRIPTION = master queue definition cross-queue PRIORITY = 50
FAIRSHARE = USER_SHARES[[user1,100] [default,1]] FAIRSHARE_QUEUES = normal short
HOSTS = hostGroupC # resource contention #RES_REQ = rusage[verilog = 1] End Queue
Begin Queue QUEUE_NAME = short
DESCRIPTION = short jobs PRIORITY = 70 # highest HOSTS = hostGroupC RUNLIMIT = 5 10 End Queue
Begin Queue
QUEUE_NAME = normal DESCRIPTION = default queue PRIORITY = 40 # lowest HOSTS = hostGroupC End Queue 2.6.4 使能配置 badmin reconfig
提交作业，并查看队列的用户动态优先级变化： bqueues –rl normal

2.7 配置抢占调度策略
配置最基本的slots抢占： Begin Queue QUEUE_NAME = short PRIORITY = 70
HOSTS = hostGroupC # potential conflict PREEMPTION = PREEMPTIVE[normal] End Queue
Begin Queue
QUEUE_NAME = normal PRIORITY = 40
HOSTS = hostGroupC # potential conflict PREEMPTION = PREEMPTABLE[short] End Queue
向两个队列提交作业，查看被preempt的作业的pending原因。
2.8 配置全局限制策略
2.8.1 限制用户运行的作业数目 在lsb.users文件中添加： Begin User
USER_NAME MAX_JOBS JL/P user1 4 - user2 2 1 user3 - 2 groupA 8 - groupB@ 1 1
10 | Page
Default 2 - End User
2.8.2 限制节点运行作业数目 在lsb.hosts文件中： Begin Host
HOST_NAME MXJ JL/U host1 4 2 host2 2 1 host3 ! - End Host
2.8.3 限制队列作业的运行限制 在lsb.queues中添加： Begin Queue
QUEUE_NAME = myQueue HJOB_LIMIT = 2 PJOB_LIMIT = 1 UJOB_LIMIT = 4 HOSTS = hostGroupA USERS = userGroupA End Queue
2.8.4 设定General limits
在lsb.resources文件定义全局general limits示例： Begin Limit USERS QUEUES user1 -
HOSTS SLOTS MEM SWP
- 20%
hostB -
11 | Page
user2 normal hostA - End Limit Begin Limit NAME = limit1 USERS = user1
PER_HOST = hostA hostC TMP = 30% SWP = 50% MEM = 10% End Limit Begin Limit
20 -
PER_USER QUEUES HOSTS SLOTS MEM SWP TMP JOBS groupA - hgroup1 - - - - 2 user2 normal - - 200 - - - - short - - - - - 200 End Limit 2.8.5 使能配置 badmin reconfig
2.9 配置提交控制脚本esub
全局esub脚本在作业被提交是调用，可以被自动的或者显式的调用从而控制用户作业提交的行为。
编辑esub.project文件在$LSF_SERVERDIR下面（chmod为可执行）： #!/bin/sh
if [ \ . $LSB_SUB_PARM_FILE
if [ \ echo \ exit $LSB_SUB_ABORT_VALUE fi fi
