brainevent.update_dense_on_binary_post_p

brainevent.update_dense_on_binary_post_p = <brainevent.XLACustomKernel object>

Low-level XLA custom-kernel primitive for update_dense_on_binary_post.

This XLACustomKernel instance dispatches the dense weight update for post-synaptic binary plasticity operation to registered backends (numba, pallas), using runtime shape/dtype metadata provided by the high-level wrapper.

The operation updates synaptic weights based on postsynaptic spike events and presynaptic trace values: for each postsynaptic neuron j that fires, weight[:, j] += pre_trace.

Beyond backend dispatch, the primitive stores JAX transformation bindings (JVP, transpose, batching, and call registration) so the operation integrates correctly with jit, vmap, and autodiff.

Available backends can be queried with update_dense_on_binary_post_p.available_backends(platform), and the default backend can be configured with update_dense_on_binary_post_p.set_default(platform, backend).
