Use detailed reports of Application Performance Snapshot to dive into deeper details regarding the performance of your application.
In addition to the summary report, Application Performance Snapshot (APS) includes a number of detailed reports that provide more insight into both hardware and MPI metrics:
- The Common Analyses section describes reports that are applicable for both MPI-based and non-MPI applications.
- The MPI Analyses section describes MPI-specific reports.
Most reports in both sections support filtering by rank, for example:
aps --report --rank 0
or by node, for example:
aps --report –node=localhost,test123
If both --node and --rank options are used, --node has no effect.
