- Jul 24, 2026 The Roofline Bound and Arithmetic Intensity How the ratio of arithmetic to bytes moved places a kernel under either a compute ceiling or a bandwidth ceiling, and why the ridge point differs between devices. gpu computing
- Jun 2, 2026 Interleaving Pages Across Nodes for Aggregate Bandwidth Why spreading a range round-robin over every node raises streaming throughput and raises pointer-chasing latency, how the interleave sequence is kept, and when the policy is worth its cost. memory systems
- Feb 4, 2025 Achieved Bandwidth Versus the Quoted Peak Why a measured stream rate falls short of the number on the datasheet, how to count the bytes a kernel really moved, and which part of the gap is structural. gpu computing
- Jan 22, 2025 Deferred Shading and the Tile-Binned Alternative Why recording surface attributes instead of shaded colour defers the expensive lighting work, and how binning fragments per screen tile reaches the same locality without the bandwidth. gpu computing
- Oct 28, 2024 Bytes Fetched per Field: Layout as a Bandwidth Decision Why array-of-structs and struct-of-arrays trade differently against cache line granularity, and how to compute the bytes moved per field actually read. performance engineering
- Nov 20, 2023 Memory-Level Parallelism and Latency Tolerance How many independent memory requests a kernel keeps in flight determines whether it can saturate bandwidth, and how unrolling and load reordering raise that count without adding warps. gpu computing
- Jul 9, 2023 Tenant Isolation and the Channels Performance Interference Travels Through Separating address spaces does not separate throughput; the shared resources that remain determine how much one tenant can slow another and which controls can bound it. gpu computing
