Image Artist Host Requirements
Required Setting: nofile 65535
The Image Artist host uses logcli to query and collect logs from the Loki service. Proper file descriptor limits ensure:
- Efficient log retrieval without interruption
- Complete log collection without truncation
- Reliable logcli query execution
Configuration: Set this limit for either:
- The specific Linux user account used for log collection
- All user accounts (system-wide setting)
External Slurm Cluster Requirements
Required Setting: nofile 65535
When using Batch Analysis with an external Slurm cluster, all worker nodes must have adequate file descriptor limits to:
- Handle multiple concurrent file operations
- Maintain stable connections during job execution
- Process large datasets efficiently
Configuration: Set this limit on all worker nodes for either:
- The specific Linux user account used for Slurm job submission
- All user accounts (system-wide setting)
How to Verify Current Limits
# Check current limit for your session
ulimit -n
