Establishing a Performance Baseline

To set a performance baseline for the improvements that follow in this tutorial, build your project with these settings:

  1. Select Project > Properties. The project property pages window appears.

  2. Select Configuration Properties > Fortran > Optimization .

  3. For Optimization, select Minimum size from the dropdown list.

  4. Select Fortran > Data > Default Real KIND > 8(/real_size:64).

  5. Rebuild the project, then run the executable (Debug > Start Without Debugging). Record the execution time reported in the output. This is the baseline against which subsequent improvements will be measured.
