Syntax

INTERNAL-MPI [on|off]

Variable

VT_INTERNAL_MPI

Default

on

Description

Allows tracing of events inside the MPI implementation. This is enabled by default, but even then it still requires an MPI implementation which actually records events. The Intel® Trace Analyzer and Collector documentation describes in more detail how an MPI implementation might do that.
