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.
Before you start using any of the Intel Trace Collector functionality, make sure to set the necessary environment variables using the
psxevars
 script available at
<install_dir>/parallel_studio_xe_<version>.x.xxx
/bin
. On Linux* OS source the
psxevars.[c]sh
 script, on Windows* OS run the
psxevars.bat
 file. This will set the required environment variables for compilers, Intel® MPI Library and Intel® Trace Analyzer and Collector, and you will be ready to trace your applications.

Product and Performance Information

1

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
