3.4. Common debug operations
This section describes and gives some examples of how GRMON is typically used, the full command reference
can be found in Appendix A, Command index.
3.4.1. Examining the hardware configuration
When connecting for the first time it is essential to verify that GRMON has auto-detected all devices and their
configuration correctly. At start-up GRMON will print the cores and the frequency detected. From the command
line one can examine the system by executing info sys as below:
