Agenda
|
|
An agenda specifies what is to be done during a Workload Automation
|
|
run. This includes which workloads will be run, with what configuration
|
|
and which augmentations will be enabled, etc. (For more information
|
|
please see :ref:`here <agenda-reference>`.)
|
|
|
|
Alias
|
|
An alias associated with a workload or a parameter. In case of
|
|
parameters, this is simply an alternative name for a parameter; Usually
|
|
these are employed to provide backward compatibility for renamed
|
|
parameters, or in cases where a there are several commonly used terms,
|
|
each equally valid, for something.
|
|
|
|
In case of Workloads, aliases can also be merely alternatives to the
|
|
workload name, however they can also alter the default values for the
|
|
parameters the Workload is instantiated with. A common scenario is when
|
|
a single workload can be run under several distinct configurations (e.g.
|
|
has several alternative tests that might be run) that are configurable
|
|
via a parameter. An alias may be added for each such configuration. In
|
|
order to see the available aliases for a workload, one can use :ref:`show
|
|
command <show-command>`\ .
|
|
|
|
.. seealso:: :term:`Global Alias`
|
|
|
|
Augmentation
|
|
Augmentations are plugins that augment the execution of
|
|
workload jobs with additional functionality; usually, that takes the
|
|
form of generating additional metrics and/or artifacts, such as traces
|
|
or logs. For more information please see
|
|
:ref:`augmentations <augmentations>`.
|
|
|
|
Artifact
|
|
An artifact is something that was been generated as part of the run
|
|
for example a file containing output or meta data in the form of log
|
|
files. WA supports multiple "kinds" of artifacts and will handle them
|
|
accordingly, for more information please see :ref:`here <artifact>`.
|
|
|
|
Classifier
|
|
An arbitrary key-value pair that may associated with a :term:`job`\ , a
|
|
:term:`metric`\ , or an :term:`artifact`. The key must be a string. The
|
|
value can be any simple scalar type (string, integer, boolean, etc).
|
|
These have no pre-defined meaning but may be used to aid
|
|
filtering/grouping of metrics and artifacts during output processing.
|
|
|
|
.. seealso:: :ref:`classifiers`.
|
|
|
|
Global Alias
|
|
Typically, values for plugin parameters are specified name spaced under
|
|
the plugin's name in the configuration. A global alias is an alias that
|
|
may be specified at the top level in configuration.
|
|
|
|
There two common reasons for this. First, several plugins might
|
|
specify the same global alias for the same parameter, thus allowing all
|
|
of them to be configured with one settings. Second, a plugin may not be
|
|
exposed directly to the user (e.g. resource getters) so it makes more
|
|
sense to treat its parameters as global configuration values.
|
|
|
|
.. seealso:: :term:`Alias`
|
|
|
|
Instrument
|
|
A WA "Instrument" can be quite diverse in its functionality, but
|
|
the majority of those available in are there to collect some kind of
|
|
additional data (such as trace, energy readings etc.) from the device
|
|
during workload execution. To see available instruments please use the
|
|
:ref:`list command <list-command>` or see the
|
|
:ref:`Plugin Reference <instruments>`.
|
|
|
|
Job
|
|
An single execution of a workload. A job is defined by an associated
|
|
:term:`spec`. However, multiple jobs can share the same spec; e.g. Even
|
|
if you only have 1 workload to run but wanted 5 iterations then 5
|
|
individual jobs will be generated to be ran.
|
|
|
|
Metric
|
|
A single numeric measurement or score collected during job execution.
|
|
|
|
Output Processor
|
|
An "Output Processor" is what is used to process the output
|
|
generated by a workload. They can simply store the results in a presentable
|
|
format or use the information collected to generate additional metrics.
|
|
To see available instruments please use the
|
|
:ref:`list command <list-command>` or see the
|
|
:ref:`Plugin Reference <instruments>`.
|
|
|
|
Run
|
|
A single execution of `wa run` command. A run consists of one or more
|
|
:term:`job`\ s, and results in a single output directory structure
|
|
containing job results and metadata.
|
|
|
|
Spec
|
|
A specification of a workload. For example you can have a single
|
|
workload specification that is then executed multiple times if you
|
|
desire multiple iterations but the configuration for the workload will
|
|
remain the same.
|
|
|
|
WA
|
|
Workload Automation. The full name of this framework.
