System Errors

System Error

Example of an Out-of-Memory (OOM) system error

At the end of each detailed report, LLview lists System Errors detected during your job run (when that is the case). These include errors emitted from the system side, which users usually do not have access to.

Common system errors include:

  • Out-of-Memory (OOM): Jobs killed by the node's oom-ripper when exceeding available memory.
  • Node Failures: Hardware or network issues on a node.
  • Interconnect Link Failures: link failures (see more details about "Flipping links" here).

Use this information to:

  • Diagnose whether failures were due to your code or system instability.
  • Identify problematic nodes or links that may need attention.
  • Correlate error timestamps with performance plots to pinpoint root causes.
