The following figure shows metric sets for the AI Engine (core) module, the memory module, and the interface
module. These metric sets are mutually exclusive. A metric from one module type (for
example, AI Engine) can be used in a
combination with a metric from another module type (for example, memory), based on
the requirements of your design. Initially, AMD recommends that
you use the heat_map
metric for the AI Engine module and conflicts metric
for memory modules. These settings are specified at run-time and therefore, you can
run them as many times as you would like with your preferences. However, some of
these metrics sets are interconnected because some use group events and others use
individual events. For example, the heat_map metric
set contains a metric that groups all kinds of stall events in a single metric along
with other metrics that group data transfer events (load/store, streams, cascade,
etc,) and vector instructions. To get a better view of which stall type(s) are
prevalent, re-run with the stalls metric set. To
better understand execution, re-run with the execution metric set.
