Intel® Trace Analyzer and Collector

Understand MPI application behavior, quickly find bottlenecks, and achieve high performance for parallel cluster applications

  • Powerful MPI Communications Profiling and Analysis
  • Scalable: Low Overhead and Effective Visualization
  • Flexible to Fit Workflow: Compile, Link, or Run
Part of Intel® Parallel Studio XE Cluster Edition

Intel® Trace Analyzer and Collector 2017 is a graphical tool for understanding MPI application behavior, quickly finding bottlenecks, improving correctness, and achieving high performance for parallel cluster applications based on Intel® architecture. Improve weak and strong scaling for small and large applications with Intel® Trace Analyzer and Collector.


  • Visualize and understand parallel application behavior
  • Evaluate profiling statistics and load balancing
  • Analyze performance of subroutines or code blocks
  • Learn about communication patterns, parameters, and performance data
  • Identify communication hotspots
  • Decrease time to solution and increase application efficiency

What’s New

  • Processor Support: Support for 2nd generation Intel® Xeon Phi™ processors added.
  • MPI Imbalance Tracing: Focused collection of MPI functions with spin-wait. This helps in two levels: it reduces the overall size of the trace files and indicates a potential load imbalance in the application.
  • MPI Snapshot Scaling: Scales lightweight MPI profiling up to 100k ranks.
