Feature List

[elliottslaughter]

I'm trying to list out all the possible features that could plausibly be exposed through the fuzzer. Just because something is on this list does not mean it is easy, or necessarily a good idea. However I think it would be worth discussing what the higher priority items would be and what items would be valuable.

• Multi-node non-control-replicated
• Multi-node control-replicated
• Fills
• Copies
• Other ops?
• More partitioning ops
• Incomplete partitions
• Deeper region trees
• Deeper task trees
• (Control) replicated subtasks
• Multiple region trees
• Multiple region requirements per task
• Creating and destroying regions (fields) dynamically
• Multi-dimensional index spaces
• Multi-dimensional color spaces
• Adversarial mapper: randomizing mapping decisions

I would prioritize the items in this order with at least a few new ones:

1. Adversarial mapper: (deterministic) randomized mapping decisions
2. Multi-dimensional index spaces
3. Deeper region trees (Don't need to go more than 3-4 levels deep)
4. Deeper task trees (Don't need to to go more than 3-4 levels deep)
5. Multi-node control-replicated
6. Collective patterns
7. Copies/Fills
8. Tracing (wait for tracing improvements)
9. Multi-node non-control-replicated
10. Creating and destroying regions (fields) dynamically
11. (Control) replicated subtasks
12. Attach/Detach/Acquires/Releases with restricted coherence
13. Multi-dimensional color spaces

The ones I didn't include I think don't actually matter that much to how the runtime works internally.
