Syntax
INTERNAL-MPI [on|off]
Variable
VT_INTERNAL_MPI

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 Collector documentation describes in more detail how an MPI implementation might do that.

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.
