2. WRF-Var Regression Test Flow Chart Run Script Script Output Future Work

3. Flow Chart WRF-var source code.Trunk.user’s tarfile Wrfvar.tar Set up Initial variables REG_ROOT = /ptmp/$user CASES = /ptmp/lir/CASE FAIL_MAIL = ( ${user}@ucar.edu ) COMPOPTS_VAL = (Serial MPI) Num_Procs = 4 GENERATE_BASELINE = FALSE COMPARE_BASELINE = FALSE. Compile.Serial.MPI Test cases.Each case is tested by Serial and MPI executable. (da_wrfvar.exe) Compare case output Compare cost function of Serial and MPI run, Get the first iteration in which cost function is different. error Exit and Send email to user with error message Regtest_var.output

4. Run Script Code comes from trunk Bsub < regtest_var.csh Code comes from user Make a tar file named wrfvar.tar Put wrfvar.tar in the same directory as regtest_var.csh Bsub < regtest_var.csh

5. Regression Test output WRF-Var source code svn info: Path: WRFDA URL: https://svn-wrf-model.cgd.ucar.edu/trunk Repository Root: https://svn-wrf-model.cgd.ucar.edu Repository UUID: b0b5d27b-6f0f-0410-a2a3-cb1e977edc3d Revision: 3590 Node Kind: directory Schedule: normal Last Changed Author: xinzhang Last Changed Rev: 3589 Last Changed Date: 2009-02-09 22:09:16 -0700 (Mon, 09 Feb 2009) WRF-Var source code are located at /ptmp/lir/wrfvar_regression.905395 WRF-Var test cases are located at /ptmp/lir/wrf_test/data/CASE Architecture AIX machine: be1104en.ucar.edu Number of MPI processes to use: 4 Test conducted by Li Ruifang 8938 MMM Test run from directory /ptmp/lir/wrf_test/wrf_var/regression/script This is a bit-wise (traditional) regression test. Compiler version info: FORTRAN: xlfrte 11.1.0.5 OS version info: AIX: bos.mp 5.3.8.2 WRF-Var compile successfully for Serial option WRF-Var compile successfully for MPI option

7. Test New Case Make a directory for new case Copy fg, ob.ascii, be.dat, namelist.input to new case directory

8. Future Work Archive Serial/MPI run’s output and compare with next run’s output. Test on Linux and Mac ( now on bluefire). Put each run’s output on wiki page Test more cases Test update_be, wrf, wps
