Struct GpuCdclWorkspace 

pub struct GpuCdclWorkspace { /* private fields */ }

Pre-allocated solver arena for reuse across multiple CDCL solves.

Owns the 30 device buffers that launch_cdcl_with_decision_ranges_gated normally allocates per call. Does NOT own CNF storage (clause_offsets/literals stay on GpuCnf).

Created via GpuCdclSolver::new_workspace. Passed as &mut to _ws solver methods.

reset_for_solve() is intentionally a no-op: the sat_cdcl_solve kernel initializes mutable state at launch. The learned-import path preserves the learned/proof arenas below out_learned_count[0] and initializes the remaining workspace buffers.

Implementations

impl GpuCdclWorkspace

pub fn assign_device_ptr(&self) -> CUdeviceptr

Device pointer of the assignment buffer (for diagnostics / reuse verification).
