Recommendations for ppc64le and aarch64 #268
Description
Hi,
what CMake flags do you recommend for building on ppc64le and aarch64?
Currently, building for these platforms gives the warnings:
- PPC64le CMake: Support OpenPower vector instruction set. #267
CMake Warning at CMakeLists.txt:253 (message):
Unrecognized system processor ppc64le. Cannot determine which hardware
features (GNU 8.2.0) supports, so hardware-accelerated implementations will
not be available.
- ARM64 CMake:
CMake Warning at CMakeLists.txt:253 (message):
Unrecognized system processor aarch64. Cannot determine which hardware
features (GNU 7.3.0) supports, so hardware-accelerated implementations will
not be available.
Afair, at least for PPC64le, AVX2 might be a thing. Should one just add the processor in the list?
See: conda-forge/blosc-feedstock#36

The support for ARM and PPC is happening in the c-blosc2 project, the new generation. Please check it out, in particular Blosc/c-blosc2#59.

Thanks for the info, that looks like a great effort! Looking forward to blosc2! :)
