Methodologies

Start cooking your performance analysis. Understand tuning techniques, performance metrics and hardware solutions to collect statistics. Next, drill down to particular tuning or configuration recipes that feature
Intel® VTune™
Profiler
or its predecessor, Intel® VTune™ Amplifier.
Recipe
Description
Understand how an application utilizes available hardware resources. Enable it to take advantage of CPU microarchitectures.
Analyze CPU utilization of your OpenMP* or hybrid OpenMP-MPI application. Identify causes for possible inefficiencies.
Examine metrics that characterize core utilization in terms of packet receiving in DPDK-based applications.
Examine PCIe Bandwidth metrics used in
Intel® VTune™
Profiler
and investigate PCIe traffic for a packet forwarding DPDK-based workload.
Analyze the efficiency of DPDK Event Device pipeline utilization in your DPDK-based application. Identify issues like inhomogeneous load distribution and worker core underutilization.
Use
Intel® VTune™
Profiler
to examine the utilization efficiency of the Intel® Data Direct I/O technology, a hardware feature of Intel® Xeon® processors.
