 # Runtime Requirements
 
  * `kernel.perf_event_paranoid` should be less than or equal to `1` for process monitoring mode and less than or equal to `0` in system monitoring mode. A value of `-1` will give the most features for non-root performance recording, at the cost of some security. Modify as follows:
 
    `sudo sysctl kernel.perf_event_paranoid=1`

  * Tracepoints and system-wide monitoring on kernels older than 4.3 requires access to debugfs.

 # Usage
 
 To monitor a given application in process monitoring execute
- 
+
  * `lo2s -- ./a.out --app-args`
 
 To monitor all activity on a system run
 
  * `lo2s -a` (stop the recording with ctrl+c)

 ## Usage with MPI
 
 You can record simple traces from MPI programs, but `lo2s` does not record MPI communication.
 To create fully-featured MPI-aware traces, use [Score-P](https://score-p.org/).
 
  * `lo2s mpirun ./a.out` Create one trace of mpirun, useful if mpirun is used locally on one node.
  * `mpirun lo2s ./a.out` Creates a separate trace for each process.

 See `man lo2s` or `lo2s --help` for a full listing of options and usage.
 
 # Quirks
 
 The `perf_event_open` kernel infrastructure changed significantly over time.

+Therefore, it is already hard to just keep track which kernel version introduced which new feature.
 Combine that with the abundance of backports of particular features by different distributors, and you end with a mess of options.
 
 In the effort to keep compatible with older kernels, several quirks have been added to `lo2s`:
