|

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:
