Normalization units
|
|
===================
|
|
|
|
A user-configurable unit by which you can choose to normalize data. Options
|
|
include:
|
|
|
|
.. list-table::

|
* - Name
|
|
- Description
|
|
|
|
* - ``per_wave``
|
|
- The total value of the measured counter or metric that occurred per
|
|
kernel invocation divided by the total number of
|
|
:ref:`wavefronts <desc-wavefront>` launched in the kernel.
|
|
|
|
* - ``per_cycle``
|
|
- The total value of the measured counter or metric that occurred per
|
|
kernel invocation divided by the
|
|
:ref:`kernel cycles <kernel-cycles>`, that is, the total number of
|
|
cycles the kernel executed as measured by the
|
|
:doc:`command processor <command-processor>`.
|
|
|
|
* - ``per_kernel``
|
|
- The total value of the measured counter or metric that occurred per
|
|
kernel invocation.
|
|
|
|
* - ``per_second``
|
|
- The total value of the measured counter or metric that occurred per
|
|
kernel invocation divided by the :ref:`kernel time <kernel-time>`,
|
|
that is, the total runtime of the kernel in seconds, as measured by the
|
|
:doc:`command processor <command-processor>`.
|
|
|
|
By default, ROCm Compute Profiler uses the ``per_wave`` normalization.
|
|
|
|
.. tip::
|
|
|
|
The best normalization may vary depending on your use case. For instance, a
|
|
``per_second`` normalization might be useful for FLOP or bandwidth
|
|
comparisons, while a ``per_wave`` normalization could be useful to see how many
|
|
(and what types) of instructions are used per wavefront. A ``per_kernel``
|
|
normalization can be useful to get the total aggregate values of metrics for
|
|
comparison between different configurations.
