MTCannon: Finalize parameter values #11978

Open mbaxter opened 1 month ago

mbaxter commented 1 month ago

Description

We have a few somewhat arbitrary parameters in MTCannon:

We should do some experimentation to optimize and finalize these values.

Inphi commented 1 month ago

We should revise these parameters after 64-bit MT-Cannon is done.

Some results on varying SchedQuantum values on the alloc.go program compiled using go1.22.

So the current values are pretty optimal for alloc.go. We should confirm this on a more complex program like the op-program.
