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

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

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.

Regression Test ouput cont’ ############################################################################### WRF-Var IS STARTING TO TEST EACH OF CASES IN /ptmp/lir/wrf_test/data/CASE ###############################################################################

CASE cwb ....................................... Serial Run ...... PASS MPI Run ...... PASS

CASE test1 ....................................... FAIL: either be.dat or ob.ascii or fg or namelist.input not exist for CASE test1

############################################################################### COMPARING SERIAL AND MPI OUTPUT FOR EACH OF CASES IN /ptmp/lir/wrf_test/data/CASE ###############################################################################

CASE cwb .............................................................................................

Output starts to differ at iteration Serial vs MPI

21 3.03954669D+04 2.75530512D+01 2.50729942D-0 | 21 3.03954668D+04 2.75530512D+01 2.50729942D-0

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

to new case directory

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
