Introduction

Note

Intel® VTune™ Profiler's Application Performance Snapshot provides overall performance characteristics of an MPI enabled application using a simple interface with faster time to results. VTune Profiler helps identify imbalances and communication issues on a single node. As a result, Intel® Trace Analyzer and Collector will no longer be included in the Intel® HPC Toolkit. It continues to be downloadable as a standalone package and it will be discontinued in 2025 or later. Customers who have- purchased Intel® Priority Support will continue to receive support. Please see Intel Trace Analyzer and Collector deprecation article for more information.

Intel® Trace Analyzer and Collector consists of the two tools: a collector with command-line interface (CLI) for tracing and an analyzer with graphical user interface (GUI) for visualizing:

libVTim

Library for tracing MPI load imbalance. See Tracing MPI Load Imbalance.

libVTmc

Correctness checking library. See Correctness Checking.

libVTcs

Library for tracing distributed non-MPI applications. See Tracing Distributed Non-MPI Applications.

VT_sample

Library for automatic counter tracing with PAPI*. See Recording Hardware Performance Information.

Utilities Description
