Create GPU code with scoped expressions to reduce register pressure #81

Closed richfitz closed 3 years ago

richfitz commented 3 years ago

This PR totally rewrites the gpu code so that rather than generating code like the CPU version where we unpack everything then run each equation in turn, we unpack locally to each expression. The hope here is that reduces the register pressure (and indeed with sircovid it does)

Fixes #75
