How to read jax jit cost analysis?

[inversecrime]

For example, how to interpret something like this:

[{'transcendentals': 90000.0, 'bytes accessed4{}': 80000.0, 'utilization0{}': 47.0, 'bytes accessed0{}': 14450348.0, 'bytes accessed3{}': 800000.0, 'bytes accessedout{0}': 10000.0, 
'utilization1{}': 61.0, 'bytes accessed1{}': 17050036.0, 'utilization3{}': 5.0, 'utilization4{}': 1.0, 'utilization2{}': 22.0, 'bytes accessed2{}': 5300000.0, 'flops': 5590022.0, 'bytes accessedout{}': 17900404.0, 'bytes accessedout{1}': 80000.0, 'bytes accessed': 50530176.0}]

I would appreciate any help!

As far as I know, these are internal stats used by the XLA compiler and there is no documentation for them.
