Patch for problem with IOVERW=1

Dear users,

If you are using the IOVERW=1 namelist option for initializing a nest from a nest input file and encounter a segmentation fault when the nest input file is being read, you need to apply a patch to the RSL and reinstall the model. This problem applies to v3.4 and has only been observed on Linux clusters. If you are using an older version of the code, please contact Rotang (michalak@ucar.edu or bourgeoi@ucar.edu) for directions.

To install the patch:

1. Download the file

http://www2.mmm.ucar.edu/mm5/mpp/helpdesk/rsl_ioserve.c

and replace MPP/RSL/RSL/rsl_ioserve.c with this new file. You may need
to use the right mouse button and select "save link as" on your
browser.

2. Completely rebuild the code:

      make uninstall
      make mpp

This fix will be included in the next release of MM5.

Thanks

Thanks to user Sai-Lap Lam of Hong Kong University of Science & Technology for his help in tracking down this bug.
