V4.5.1 Status Updates

• Feature window has closed
• currently accepting: Bug fixes and Minor but important improvements
• On track for release before LDMSCON2025

Summary from the LDMS Job ID Meeting

• Problem: Current uint64 Job IDs cannot handle:
  • Schedulers reuse/duplicate Job ID
  • Hierarchical job structures
• Goal: Create standardized string-based Job ID format with enhanced querying capabilities
  • Enable human-readable job_id
  • Support hierarchical job structures
  • Enable hierarchical metric data queries by job_id
• Implementation approach:
  • Convert job_id from uint64_t to string with configurable delimiter
  • Keep job_id simple: use what users see in CLI
  • Place additional content in a new job_metadata field
  • Tag job_id to system-wide metric sets
• Next steps:
  • Summary document being prepared on job information caching
• Q&A
  • Planned to provide a list of prioritized bug fixes and improvements for v4.5.1 at the next User Group Meeting
