Using ROCmInfo
================

The ROCmInfo command provides information about the Heterogenous System Architecture (HSA) system attributes and agents. Each agent represents a device and a device can be a CPU or a GPU.

The output has the following two sections:

* HSA System Attributes - List of general information of the system.

* HSA agents - List of devices in the system.

See the following example output of the ROCmInfo command on a system with MI300X:
