## Inspect runtime profiling

Use `PYTHONPATH=. extra/viz/cli.py --profile` to list all traced devices.

List top slowest kernels on a device: `--profile --device "AMD"`
List samples of a kernel on a device: `--profile --device "AMD" --kernel E_3`

## Inspect codegen and PatternMatcher

Use `PYTHONPATH=. extra/viz/cli.py --rewrites` to list all traced kernels.

List all codegen steps for a kernel: `--rewrites --kernel E_3`
Get source code: `--rewrites --kernel E_3 --select "View Program"`
Inspect a graph rewrite: `--rewrites --kernel E_3 --select "initial symbolic"`
