| 1 | HOW TO DO REGRESSION TESTS OF THE FORTRAN CODE |
|---|
| 2 | |
|---|
| 3 | 1. Go to flex_extract/Testing/Regression/FortranEtadot |
|---|
| 4 | 2. Download the tarball containing the input files and reference outputs |
|---|
| 5 | 2. Untar the tarball |
|---|
| 6 | 3. Create a wirking directory: mkdir Work |
|---|
| 7 | 4. Compile the unmodified Fortran code with makefile_fast and makefile_debug |
|---|
| 8 | (is in flex_extract/Source/Fortran) |
|---|
| 9 | 5. Run a regression test to see whether the current Fortran code gives |
|---|
| 10 | output consistent with the reference output. |
|---|
| 11 | If not, carefully check why (machine-dependent small deviation?) |
|---|
| 12 | The output from the regression run is in 'Outputs' (automatically created). |
|---|
| 13 | If you need a new reference, you could remove or rename 'Outputs_ref', |
|---|
| 14 | and then run |
|---|
| 15 | ./mk_outputdirs.sh |
|---|
| 16 | ./run_ref.sh |
|---|
| 17 | to create a new reference version. |
|---|
| 18 | 6. Work on the code and use the 'run_ref.sh' script to test your results. |
|---|
| 19 | |
|---|
| 20 | Note 1: The regression tests except those with "high" in their name will |
|---|
| 21 | altogether run in about 1 minute. The "high" tests (hemispherical data) |
|---|
| 22 | can take many minutes and also require up to ca. 20 GB of memory. |
|---|
| 23 | Therefore, the script can be invoked as |
|---|
| 24 | ./run_ref.sh omithigh |
|---|
| 25 | to omit the "high" tests. For single development steps this should be |
|---|
| 26 | sufficient. When you are satisfied, run the "high" tests at the end. |
|---|
| 27 | Note 2: The test scripts contain |
|---|
| 28 | export OMP_NUM_THREADS=4 # you may want to change this |
|---|
| 29 | export OMP_PLACES=cores |
|---|
| 30 | You should set OMP_NUM_THREADS to the number of physical cores of your |
|---|
| 31 | test machine or less. |
|---|
| 32 | OMP environment variables are explained on |
