### Slurm Profiler
!!! hint "Easy to use performance visualization of entire batch jobs"
The [Slurm Profiler](../jobs_and_resources/slurm_profiling.md) gathers performance data from every
task/node of a given [batch job](../jobs_and_resources/slurm.md).
It records a coarse-grained [trace](#trace) for subsequent analysis.
[Instrumentation](#instrumentation) of the applications under test is not needed.
The data analysis of the given set of system metrics needs to be initiated by the user with a
command line interface.
The resulting performance metrics are accessible in a simple graphical front-end that provides
time/performance graphs.
