- Aug 13, 2026 Bump Allocation and the Cost of Arena Reset Why a pointer-increment allocator can serve thousands of requests in a few cycles, what alignment bookkeeping it still needs, and the ownership rule that makes wholesale reset safe. memory systems
- Jun 23, 2025 Arena Allocation and the Cost of Releasing Everything at Once Bump allocation, region lifetimes, and why destroying a whole arena is cheaper than freeing its objects, together with the reuse patterns that keep it from growing. systems programming
- Jun 19, 2024 Static Memory Planning from Tensor Liveness Intervals Turning a liveness interval per tensor into an offset in one arena, why interval-graph colouring is optimal for monotone lifetimes, and where greedy packing loses bytes. inference systems
- Mar 5, 2023 Arena Allocation and Ownership by Convention Replacing per-object ownership with region ownership: the bump-pointer fast path, the constraints it imposes on destructors, and where the pattern appears in real allocators. programming languages
