We should support all different retilings (x*packing1, 128) <-> (y*packing2, 128) with any dtype in this cl at this moment. The efficient relayout with scratch brings significant improvements on current retiling in <= TPUv4 and retiling with (packing, 128) in TPUv5. All missing retiling supports are added in this cl, including increase sublane retiling and packed type retiling. PiperOrigin-RevId: 676982957
jaxlib: support library for JAX
jaxlib is the support library for JAX. While JAX itself is a pure Python package, jaxlib contains the binary (C/C++) parts of the library, including Python bindings, the XLA compiler, the PJRT runtime, and a handful of handwritten kernels. For more information, including installation and build instructions, refer to main JAX README: https://github.com/jax-ml/jax/.
