Time Synchronization Setup for Slurm Cluster

1. Check Head/compute Node Status

# Verify time synchronization status on jupyter node
## check Head node
ssh root@jupyter "timedatectl status"
## check Compute node
ssh root@node9 "timedatectl status"

2. Configure Compute Node Time Sync

2.1 Set NTP Configuration

# Configure timesyncd to use head node as primary NTP server
ssh root@node9 "cat > /etc/systemd/timesyncd.conf << EOF
[Time]
NTP=192.168.33.5    # Head node IP
FallbackNTP=ntp.aliyun.com ntp1.aliyun.com
EOF"

2.2 Apply Configuration

# Restart the timesyncd service
ssh root@node9 "systemctl restart systemd-timesyncd"

# Force time synchronization
ssh root@node9 "timedatectl set-ntp true"

2.3 Verify Configuration

# Check synchronization status
ssh root@node9 "timedatectl status"
