| In this section, the reader can find all the important HIP environment variables. The full collection of the ROCm environment variables is on the :doc:`ROCm environment variables page<rocm:reference/env-variables>`. |

I think this could use a little clarification as to the environment variables displayed here versus the additional variables shown on the referenced pages. Why are these environment variables worth looking at here, but not the others?
Also, I think the reference needs a space:
:doc:ROCm environment variables page <rocm:reference/env-variables>

| | A list of device indices or UUIDs that will be exposed to applications. | ||
| - Example: ``0,GPU-DEADBEEFDEADBEEF`` |

Is GPU-DEADBEEFDEADBEEF and actual UUID or is it intended to represent something else?

I think it's funny and kudos for the original author. I can change it to a more realistic one.

This link page has 5 environment variables while here we see only three. Why the different numbers and what do these three have that the others lack?

OMP_DEFAULT_DEVICE variable is for OpenMP runtime, HIP_VISIBLE_DEVICES and CUDA_VISIBLE_DEVICES added as one line.

| * The performance can be improved at `GROMACS <https://github.com/ROCM/Gromacs>`_ HIP backend, when the ``ROC_ACTIVE_WAIT_TIMEOUT=0`` and ``ROC_USE_FGS_KERNARG=0`` environment variables are set. |

It is interesting to me these tips mention environment variables that are not discussed on this environment variables page. Where do I find out about ROC_ACTIVE_WAIT_TIMEOUT and ROC_USE_FGS_KERNARG?

There are more levels here. Please refer to clr/rocclr/device/util/debug.hpp
LOG_MEM = 131072, //!< (0x20000) Memory allocation
LOG_MEM_POOL = 262144, //!< (0x40000) Memory pool allocation, including memory in graphs
LOG_TS = 524288, //!< (0x80000) Timestamp details
