Time to build the clash-lang Haskell to VDHL/Verilog/SystemVerilog compiler. This system builds on only a subset of the cores with runnable processes changing.There is a noticeable amount of interrupts.
Topdown profile shows frontend stalls as high with backend stalls next in a range.
AMD metrics show two cores on average, no floating point. One in five instructions is a branch.
