I'm just going to turn off accumulating to fp32 for now. I don't want to
manually look at every single schedule ever written to check for correctness.
Turning things off all the unit tests except one pass. The one that doesn't
pass is the problem described by @Lunderberg. This ones seems trickier since I
don't understand how cuda codegen works at all:
```

len(mod_dev.functions) != 0 else None
