How to use the totalview-debugger on hicegate and bicegate

Starting from Rev 223, PALM allows using of the totalview-debugger on hicegate and bicegate. The following gives a brief instruction:

1. Add an additional block "lcsgih parallel debug" in the mrun configuration file (.mrun.config) which has to contain a line:

         %totalview      true           lcsgih parallel debug
   

   totalview should work with the mpt but also with the mvapich library.

2. Copy .mrun.config into directory ~/palm/current_version on hicegate/bicegate. Also copy parameter-file and other files required for the run to the respective subdirectories under ~/palm/current_version (e.g. JOBS/...).

3. Log in on hicegate/bicegate (it is essential to use "-X" as ssh-option !!) and execute the following commands (for a debug-run with 4 cores on one node):

         msub -I -X -l nodes=1:ppn=4 -l walltime=1000 -q testq
                     # starts a so-called interactive job
         module load intel.compiler
         module load mpt    # or other mpi-version
         module load netcdf
         module load totalview
   
         mrun -d ....
              # usual mrun-call, options as required by user, but WITHOUT option -h
              # values given for -X and -T options must match the msub settings,
              # e.g. in this case "-X4 -T4"
   

   After short time, the totalview-window should open (if testq is filled with other jobs, you may have to wait for a longer time).

4. After closing the totalview window, don't forget to leave the interactive job with "exit" command.

The ISV online documentation server ​https://www.hlrn.de/doc/ serves the documentation for totalview 8.6.1-1 (see the Online Documentation Overview ​https://www.hlrn.de/home/view/System/DocumentationOverview for access information).
