WRF on ARM64 (aarch64) architecture systems with the NVIDIA HPC SDK Compilers

[kagelos]

WRFV4.5 adds support for ARM64. Does anyone have any experience with the platform? Does this induce performance improvements?

Hi,
Our group at NCAR does not yet have access to the ARM64 architecture. It looks like the modification was given to us by someone from Nvidia, and I assume it was tested by them. If no one else from the community gets back to you on this post, I would recommend trying to reach out to the Nvidia group to see if you can get some information. If you find out anything, and have time, please post what you learn to this thread so other users will know the answer! Thanks.
