GPU-Initiated DMA Copy Engines in RCCL and rocSHMEM
- 13 November 2026
As GPU-accelerated workloads scale across multiple devices and nodes, the efficiency of inter-GPU communication becomes a decisive factor in overall application performance. This is especially true for inference workloads, where communication sits on the critical path and traditional approaches to overlapping compute and communication fall short without fine-grained, kernel-level orchestration.
