-Wrap tight loops with

-* Declare loop-local variables with `private='[...]'`.
-* Allocate large arrays with `managed` or move them into a persistent

-* **Do not** place `stop` / `error stop` inside device code.
-* Must compile with Cray `ftn` and NVIDIA `nvfortran` for GPU offloading; also build CPU-only with
-  GNU `gfortran` and Intel `ifx`/`ifort`.

-Some examples include:
-- `$:GPU_ROUTINE(parallelism='[seq]')` - Marks GPU-callable routines
-- `$:GPU_PARALLEL_LOOP(collapse=N)` - Parallelizes loops
-- `$:GPU_LOOP(parallelism='[seq]')` - Marks sequential loops
-- `$:GPU_UPDATE(device='[var1,var2]')` - Updates device data
-- `$:GPU_ENTER_DATA(copyin='[var]')` - Copies data to device
-- `$:GPU_EXIT_DATA(delete='[var]')` - Removes data from device
