IBM explains how KTIR and the Dataflow Scheduler compile kernels for Spyre
AIIBM's PyTorch Blog post describes the MLIR backend that compiles Spyre kernels, covering KTIR, the Dataflow Scheduler, DataflowIR and SpyreCode. The open-source scheduler turns KTIR kernels into double-buffered load, compute and store pipelines routed through the memory hierarchy.
AIWhy it matters.
The post traces how one compiler contract turns hardware placement decisions into an executable program, useful for engineers bringing up ops on scratchpad-based accelerators.
