The latest release of ArrayFire (3.9.0) crashes when run against newer NVIDIA Blackwell cards. This release was built against CUDA 12.2; it looks like at least 12.8 is required to expose features needed to run the latest generation cards.
It's possible but much more tedious to build from source for Blackwell support. It would be great to have an updated release and set of binaries that is built against the newer CUDA version as a large number of users rely on the binary-only installation to deploy ArrayFire. This is no longer possible for those running newer hardware.
