By default, the
libVTmc
library does not write a tracefile. To perform correctness checking of an MPI application, enable trace collection and link your application with the
libVTmc
library. Do the following:
Linux* OS
  1. Switch the
    CHECK-TRACING
    configuration option to
    on
    to enable Intel® Trace Collector to record the correctness checking reports to the tracefile. For example:
    $ export VT_CHECK_TRACING=on
  2. Run your application with the
    -check_mpi
    option of
    mpirun
    . For example:
    $ mpirun -check_mpi -n 4 ./myApp
Windows* OS
  1. Relink your application with the
    libVTmc
    library using the
    -check_mpi
    compiler option. For example:
    > mpiicc -check_mpi myApp.c
  2. Run your application with the
    CHECK-TRACING
    configuration option enabled. For example:
    > mpiexec -n 4 myApp.exe --itc-args --check-tracing ON --itc-args-end
Use Intel® Trace Analyzer to view correctness checking events.

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.
