How to Compile GSI 2.0 of programs on ABE

*Can be downloaded from the DTC GSI site. Enter the email address in the line and press enter. You will only be asked to register the first time an email address is used. After that, only the email is needed.

1. While in your home directory on abe, open the file .soft with your favorite text editing program. ex. (vi , pico)
2. Make sure that the following tags are included if using Portland Group compilers

   @teragrid-basic
   @default
   @pgi-10.8
   @teragrid-dev
   +netcdf
   +pgi-10.8
   NETCDF = "/usr/apps/lib/netcdf"
   WRF_DIR = "/u/ac/username/WRFV3"

3. After updating .soft, use the command

   resoft

1. Download GSI, which will come in the form of comGSI_v2.tar.gz.
2. Then transfer the file to abe with the command

    scp file username@login-abe.ncsa.teragrid.org:/u/ac/username 

   1. note that if you don't have the ability to access abe from outside the teragrid's web based portal, this might not work. You would then have to use the teragrid portal file transfer application.
3. Once the file is on abe, you must untar and ungzip the file.

    tar xzf filename 

4. Move into the new directory and use

   ./configure

   1. Use the same compiler as used in the construction of the associated WRFV3 linked in the .soft
5. To compile use

   ./compile >& compile.log &
   
   tail -f compile.log

6. To see if the compilation was successful, check run directory to see if gsi.exe was created.
7. A tutorial with additional compilation instructions and instructions on test cases can be found here.
