@imciner2 @giordano Any ideas what's happening here?

On my local machine (M2 Mac), I see:

[ Info: blis_jll yields BLIS installation: /Users/viral/.julia/artifacts/043b26a2c0a497f9e28fa1ffa072488cc3e43e58/lib/libblis.4.0.0.dylib.

libblis: frame/base/bli_gks.c (line 257):
libblis: Default MC is non-multiple of MR for one or more datatypes.

That's interesting. Can you run with BLIS_ARCH_DEBUG=1 set to see which kernel it is trying to use? That error message apparently means there is a problem with the parameters of the kernel:

	// Verify that cache blocksizes are whole multiples of register blocksizes.
	// Specifically, verify that:
	//   - MC is a whole multiple of MR.

Doesn't seem to yield much more info:
