Introduction

Intel® Trace Collector is a tool for tracing MPI applications. It intercepts all MPI calls and generates tracefiles that can be analyzed with Intel® Trace Analyzer for understanding the application behavior. Intel® Trace Collector can also trace non-MPI applications, like socket communication in distributed applications or serial programs. The tool was formerly known as Vampirtrace* (VT), which is why the VT abbreviation is present in the names of some of components and variables.
