WRF Model Version 2.0.3.* : Known Problems and Fixes

Compiling WRF 2.0.3.1 on Altix Using Intel Compiler 8.* (posted 04/19/05)

Problem: When compiling on Altix using some version of the Intel 8.* compiler, two errors may occur. One is a complaint about rsl_socket, and the other may be at the loading stage.

Solution: rsl_socket is not needed, and rsl_socket.o can be removed from external/RSL/RSL/makefile.core. Also add -lcprts to the loader flag.

Fix for retaining correct skin temp over seaice (posted 03/14/05)

Problem: Using recent Nam/Eta data as input to WRF real-time runs in winter when frozen lakes are present, correct landuse and skin temperature may be lost during pre-processing.

Solution: Download the modified module_initialize_real.F.fix to WRFV2/dyn_em/ directory, module_soil_pre.F.fix to WRFV2/share/ directory, and Registry.EM to Registry/ directory. Remove the .fix suffix, and recompile. This needs to work together with a fix in SI.

Compiling and Running WRF 2.0.3 on SGI IRIX 64 (posted 12/16/04)

Problem: OpenMP option was errornously included in SGI MPI/RSL option, which may cause the code to run significantly slower.

Solution: Comment out the OpenMP option in configure.wrf, or in arch/configure.defaults for SGI O2K DM IRIX64 DM-Parallel section.

Compiling WRF 2.0.3 on HP-UX (posted 12/16/04)

Problem: The ERROR_TEST macro near the beginning of the file frame/module_tiles.F expands to code that exceeds column 132.

Solution: Edit the file, and remove ' "set_tiles:",' in line 15.

Error When Using Binary I/O (posted 12/09/04)

Problem: When using native binary I/O format (io_form_* set to 1 in the namelist), the time-independent meta data was not correctly input from a dataset being read, causing the run to abort with an error message complaining of a size mismatch between the domain size in the dataset and the size specified in the namelist. The problem does not affect other I/O format options (such as netCDF). (Note, the supported post-processing tools do not yet support binary I/O.)

Solution: download a modified routine, io_int.F90, and replace the one in directory external/io_int/. Type 'clean -a', and recompile.

Compiling WRF 2.0.3 Using Intel Compiler (posted 11/17/04)

Problem: An important compilation flag is missing from the WRF tar file downloaded before Novenber 17, 2004. This could result in incorrect results.

Solution: download the latest tar file, or add -mp to FCBASEOPTS

Compiling WRF 2.0.3 on NCAR IBM bluesky

Problem: The OpenMP compile option on NCAR's IBM (bluesky) is not working.

Solution: Use MPI option, and wait IBM to correct compiler bugs.

Compiling WRF 2.0.x on a Linux computer using PGI compiler version 3.x

Problem: The compiler appears to have trouble with some 'equivalence' statements in module phys/module_ra_gfdl.F, and the compile log shows errors like 'Conflicting equivalence between t4 and table 3'.

Solution: download a modified version of module_ra_gfdleta.F for 2.0.3 and recompile.
