Network IO, Intel Data Direct IO (DDIO), Microarchitecture Simulation
Summary :
DDIOSim is an open-source, cycle-accurate simulator combining QSim and ChampSim to model Intel’s DDIO technology, which allows direct NIC-to-Last Level Cache (LLC) data transfer. The tool enables researchers to explore design, performance, and system interactions of DDIO-based network architectures, assessing cache/DRAM use, throughput, and latency for diverse workloads
