Characterized the early IPU's tile-local SRAM, communication and arithmetic organization, publishing reproducible microbenchmark techniques and memory-bandwidth behavior under different load widths and block sizes.
Scientific scope
Characterized the early IPU's tile-local SRAM, communication and arithmetic organization, publishing reproducible microbenchmark techniques and memory-bandwidth behavior under different load widths and block sizes. These four Citadel researchers characterized Graphcore hardware; they are not credited as its inventors. Graphcore supplied an early test system and reviewed the manuscript, while funding remained Citadel's. Local working sets, compiler/alignment, thread occupancy and workload shape constrain results; neither theoretical peaks nor local-memory tests establish universal end-to-end GPU superiority.

The linked original sources describe the stated contribution and its evidence limits. WRS has not independently rerun the experiments or certified a proof.
