Description

Given we do a run-time compile of OpenCL kernels, "how hard can it be" to do things like

  1. Dynamic-compiler format, that whips up a semi optimized OpenCL kernel and runs it.
  2. An External mode, that wips up an OpenCL kernel for producing candidates.

It's just a matter of really wanting to do it. Both ideas have tumbled around in my head for quite a while.

Research direction

The issue names no files, tests, or entry points. Start by reviewing the existing runtime OpenCL kernel compilation path and how candidate-generation modes are structured; define the scope and acceptance criteria for dynamic-compiler and external modes before implementation.
