Graphcore IPU/Poplar: local-memory graph execution with BSP coordination

What changed

Designed fine-grained processors with distributed on-chip SRAM and compiler-mapped static graph programs, coordinating local computation and exchange through bulk-synchronous execution.

Scientific scope

Designed fine-grained processors with distributed on-chip SRAM and compiler-mapped static graph programs, coordinating local computation and exchange through bulk-synchronous execution. Original2017 technical account is prelaunch design disclosure, not a verified shipment or benchmark report. BSP, graph partitioning and recomputation are inherited; finite SRAM and compiler balancing/communication costs remain. Claims of arbitrary-algorithm superiority, perfect interconnects or unconditional freedom from every race/deadlock are not adopted. Simon Knowles is the account's author, not a complete chip-inventor list; corporate authorship retained.
