Checking Results#
To check whether your MPI implementation is working correctly, you can
use the CPP flag -DCHECK.
Activate the CPP flag -DCHECK through the CPPFLAGS variable and
recompile the Intel(R) MPI Benchmarks executable files. Every message
passing result from the Intel(R) MPI Benchmarks are checked against the
expected outcome. Output tables contain an additional column called
Defects that displays the difference as floating-point numbers.
Note
The -DCHECK results are not valid as real benchmark data.
Deactivate -DCHECK and recompile to get the proper results.
