The basic timing columns are translated into canonical form:

  • time will contain individual repetition time in seconds

  • total will contain aggregate execution time at the end of repetition in seconds

  • index will contain the index of the measurement in the run starting from 1

Additional metadata is included as factor columns:

  • vm is a hash of all configuration metadata and can be used to distinguish incompatible measurement configurations

  • vm_name is the name of the virtual machine

  • vm_version is the version of the virtual machine

  • vm_configuration gives concatenated command line arguments

  • run is a unique identifier of the run

  • benchmark is the name of the benchmark
