Application Performance Snapshot User's Guide for Linux* OS
Use Application Performance Snapshot for a quick view into a shared memory or MPI application's use of available hardware (CPU, FPU, and memory). Application Performance Snapshot analyzes your application's CPU and FPU usage, I/O and memory footprint, memory access stalls, and MPI and OpenMP* utilization. After analysis, it displays basic performance enhancement opportunities for systems using Intel® platforms. Use this tool as a first step in application performance analysis to get a simple snapshot of key optimization areas.
Application Performance Snapshot is available as a free product download from the Intel® Developer Zone at https://software.intel.com/performance-snapshot and is also available pre-installed as part of Intel® Parallel Studio or Intel® VTune™ Amplifier.
Starting from the 2018 Beta release, the updated Application Performance Snapshot for Linux* OS includes most of the functionality previously available in the MPI Performance Snapshot. MPI Performance Snapshot is no longer available as a separate tool.
