SYMBOL


The
SYMBOL
option is a shortcut for
STATE "**:<pattern>"
.
Define the
SYMBOL
setting in the configuration file if you want the Intel® Trace Collector to collect data on all
Allreduce
functions, both from MPI and from user code.
To do this:
  1. Create a new configuration file.
  2. In the configuration file, specify the
    SYMBOL
    option:
    SYMBOL *:Allreduce ON
  3. Save the configuration file:
    my_settings_symbol.conf
    .
  4. Set the
    VT_CONFIG
    environment variable to the directory that contains the configuration file:
    VT_CONFIG=/<
    configuration file path name
    >/my_settings_symbol.conf
  5. Run the application.
    Linux* OS:
    $ mpirun -trace -n 4 ./poisson
    Windows* OS:
    > mpiexec -n 4 poisson.exe

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.
