Intel Data Direct I/O Performance With Intel VTune Profiler
Improve Intel DDIO Workload Performance with Intel VTune Profiler, One hardware feature included in Intel Xeon CPUs is Intel DDIO technology
PCIe Traffic Summary, which includes metrics for both outgoing (caused by the CPU) and incoming (caused by I/O devices) PCIe traffic
I/O operations were sluggish and processor cache was a scarce resource prior to the development of Data Direct I/O technology
These measurements aid in the computation of CPU/IO conflicts, latency for incoming read/write requests, PCIe bandwidth and efficient use, and other factors
Metrics to assess the workload’s effectiveness in re-mapping incoming I/O device memory locations to various host addresses using Intel VT-d technology
Intel Integrated I/O technology Intel DDIO was launched in 2012 for the Intel Xeon processor E5 and E7 v2 generations
Improve the performance of Intel DDIO workloads using Intel VTune Profiler, a performance analysis and debugging tool driven by oneAPI
