state-space-renderer's Issues

benchmark cleanup

Use google benchmark function to cleanup loops, initialization, etc.

Renderer class

Generate Renderer class with some implementations:

  • JackRenderer
  • RandomRenderer

XGEMM generates memory leak

Running valgrind gives the following summary:
