[features]
# The LIF tick on the GPU: a passthrough to `flybrain-core/cuda`, so a release build can carry
# the backend without naming the inner crate on the command line
# (`FLY_CARGO_FEATURES=cuda infra/build/build-flysim.sh`). Off by default.
#
# Compiling it in does not turn it on. The backend attaches only when `FLY_LIF_CUDA=1` is in
# the process environment, and `cudarc` is built with `dynamic-loading`, so a CPU-only run of a
# CUDA-capable binary never opens `libcuda` — `ldd` on it lists no CUDA library at all. The
# compatibility string is unaffected, because the GPU tick is bit-exact with the CPU one
# (`infra/docs/lif-cuda-spike.md`, `infra/docs/cuda-on-dev.md`).
