No GPU is needed +for any check in this module (`CUDA.functional()` may be `false`), so tests +built on it can guarantee GPU compilation without requesting CUDA devices. + +Given a call `f(args...)` with CPU (`Array`-backed) arguments, this module can +run four analyses: + + 1. `:cpu` — JET's optimization analysis of the call itself, equivalent to + `JET.@test_opt f(args...)`: reports every runtime dispatch or optimization + failure over the CPU argument types. + 2. `:host` — the same JET analysis over the argument types as they would + appear on a machine with a GPU: every `Array` becomes a `CuArray`, CPU + devices become `ClimaComms.CUDADevice`, and `DataLayouts` scopes are + recomputed. This is what `JET.@test_opt` sees in GPU CI jobs, and it + catches host-side instabilities in kernel launch code. + 3. `:kernel` — GPU device code analysis. The arguments are converted with the + same `Adapt`/`CUDA.KernelAdaptor` rules that real kernel launches use + (with `Array` leaves standing in for `CuArray`s), and the call is treated + as a kernel body. Two analyses run on it: + - GPUCompiler's LLVM IR validation, which catches `InvalidIRError`s + (dynamic dispatch, GPU-illegal operations) at the stage right before + the IR would be compiled to PTX; and + - JET's optimization analysis over CUDA's device method table, so that + device intrinsics like `threadIdx` are not treated as dead code. + 4. `:pointers` — a scan of the adapted arguments for host arrays that + survived adaptation. A field that remains an `Array` after the + `KernelAdaptor` runs corresponds to a host pointer inside a kernel + argument on a real GPU, which causes an illegal memory access at runtime + (this cannot be caught by compilation alone). + +The `:kernel` check relies on scope-based dispatch: converting a `DataLayout` +to its kernel-side representation gives it the `ThisKernel` scope, so calling +the same user-facing function on adapted arguments follows the device +implementation.
