问题描述
我最近为具有一个节点和72 cpus的服务器配置了一个排队查询系统。 这是conf文件：
# slurm.conf file generated by configurator easy.html.
# Put this file on all nodes of your cluster.
# See the slurm.conf man page for more @R_457_4045@ion.
#

#
#
# COmpuTE NODES
NodeName=hoffmann cpus=72 CoresPerSocket=18 ThreadsPerCore=2 State=UNKNowN
PartitionName=queuing Nodes=hoffmann Default=YES MaxTime=INFINITE State=UP
运行良好，但有一个局限性，无论我问什么，它都允许所有作业使用cpus，其结果是一次只能运行一个作业。 这是我正在运行的批处理：
#!/bin/bash
#SBATCH --job-name=test
#SBATCH --output=/home/ubuntu/test.out
#SBATCH --nodes=1
#SBATCH --ntasks=1
#SBATCH --cpus-per-task=1
#SBATCH --time=500:00
sleep 50
echo 'done'
当我启动其中两个并查看：sinfo -o“％all”时，我看到所有节点都已分配。我猜我在conf文件中犯了一个错误。知道会是什么吗？ 谢谢
解决方法
您需要在以下位置取消注释该部分：
# ---- Here to get jmore than one job running per node,seems to causedata transmission failure ----
因此请取消注释SelectType和SelectTypeParameters。
您是否已取消注释，并自行在其中添加了注释？它不会引起任何故障。
