Tile-Based Decompression in Compiled GPU Engines

Modern GPUs reach record analytical performance only when a query's working set fits within its GPU memory budget, and that budget is under growing pressure: GPUs are partitioned and shared, working sets are outgrowing high-bandwidth memory (HBM), and HBM is a fixed on-device resource whose per-dollar capacity has stag...

Cracks in the Memory Wall: Data Systems On Disaggregated Memory

The growing disparity between processor core scaling and memory bandwidth has exposed the physical and economic limits of processor-centric database architectures. While Compute Express Link (CXL) and other emerging technologies enable a necessary shift toward memory-centric, disaggregated topologies, it also introdu...

The Free Lunch Has a Queue: Characterizing On-chip Compression Accelerators for Analytics

It is found that hardware offload is not a universal replacement for CPU compression, and compression should be scheduled dynamically: route blocks by codec, operation, size, and accelerator load; cap per-device sub-mission concurrency; and fall back to software when offload is unsupported or saturated.
