final class

VulkanAadKernel

A recorded tape compiled into a Vulkan compute pipeline and replayed one scenario per invocation.

Recording and SPIR-V compilation happen once, in compile; after that a replay costs one (or, for very large batches, a handful of) vkCmdDispatch submissions plus a small per-workgroup read-back, no matter how many scenarios it covers. Inputs are storage-buffer contents rather than baked-in constants, so setInput re-values a shifted parameters with no re-record and no re-compile.

RADV on a shared-memory APU has no display-driver watchdog as aggressive as NVIDIA's TDR, but the kernel DRM scheduler still has a hang check in the seconds range, so a dispatch is kept about an order of magnitude below it.
