Tanh on Rust/Oxide

Hyperbolic Tangent

⏳ PENDING — not yet measured

Operation

Operation	Tanh (`bpd_tanh`)
Formula	f(x) = (exp(x) - exp(-x)) / (exp(x) + exp(-x))
Category	Transcendental (exp)

Kernel Specification (Prolog/Logtalk)

This is the backend-neutral op_expr fact that specifies the operation. The same term is lowered to LLVM IR, CUDA C, MLIR, and every other backend — one specification, many targets.

op_expr(bpd_tanh,
    call(tanh, var)).

Backend

Backend	Rust/Oxide (`rust_oxide`)
Target	gpu
Description	Rust/cuda-oxide. Compiled with rustc + cuda-oxide runtime.

Verification

This (operation, backend) pair has not yet been measured. When the backend emitter and verification infrastructure are ready, this cell will be tested against the PyTorch reference.
