Who are Mat1 and Mat2 and why won't they leave me alone?
I get this error or a tensor not matching error while running in Stability Matrix nearly every other wf. This has been happening for over a month- and I've done a fresh install twice with same result. Why do I keep getting this half, mat1 and mat2, tensor not matching errors and how do I fix this issue?
Error occurred when executing KSampler:
mat1 and mat2 must have the same dtype, but got Half and Float
I think this issue was a problem with an older version of IPEX, v2.1.20+xpu, but the latest version should fix things, v2.1.30+xpu, which I haven't ran into yet since upgrading.

IIRC, current official Windows wheels lack AOT compilation, huge long startup time every single time (not even caching!), Nuullll had compiled 2.1.20 wheels with AOT for Windows, but not newer ones. But, if they do have AOT now, then cool!
Also, BF16 is faster on Intel anyways.
Ah okay, apparently, it's still an open issue, that does somewhat suck for owners until Intel gets up to speed on that. BF16 is faster than FP16 on Intel Arc Alchemist GPUs but it is unknown at this point whether the lower precision datatypes in Battlemage will be implemented in hardware or not. I suspect not.
