Wednesday, August 23rd
Topic proposals:
- How does embedded field view work and what can you do with it?
- General introduction
- see slides from GT4Py workshop (Enrique)
- unary operations
- binary operations on same domain
- intersection
- remap
- Debugging example (Hannes)
- Discussion points:
- Discuss slicing and offset syntax `field[I[1]]` vs `field(I[1])`
- How to represent staggering?
- `fbuiltin` dispatching to the correct field implementation.
- How to decide the output in a mixed field implementation?
- How to deal with structures of fields?
- `log([a,b,c])`, jax pytrees
- Combined IR
- How would an IR look like that combines a local view (Iterator IR) and a field view (something like FieldOperatorAST) in a single IR.
- Why do we think this is a good direction? Pros and cons? What are the consequences for development?
- Discussion points:
- How ot represent `concat` in local view?
- Different output domain in field_operator tuple returns, especially one is subset of other
- JIT vs AOT compilation
- Introduction:
- Summarize the current state.
- Discussion points:
- Which direction do we want to go:
- JIT is the default with mechanism to allow AOT
- AOT is the default, but allow to defer some definitions to runtime
## Slicing and offset syntax
```python!
v(V2V)[V2V[0]](V2V[0])
v(V2V[0])(V2V[0])
f_v[I(-1):I(5)] == f_v[I[-1:5]] ??
```
`f_v = V2E >> f_e` would be nice but operator precedence is bad
