mkprepbufr

Extract the prep step of the global-workflow related to generation of prepbufr files. This repository in essense set's up the execution of JGLOBAL_PREP on Hera and WCOSS_DELL_P3 (Venus and Mars).

Lazy Instructions

1. Clone this repository and cd into it.

   $> git clone https://github.com/aerorahul/mkprepbufr
   $> cd mkprepbufr
   

2. Edit the top section in config/config.base to configure your run between the BEGIN and END comments:

   • change the experiment parameters; e.g. PSLOT etc.
   • provide path to obsproc builds in HOMEobsproc_prep and HOMEobsproc_global. Pre-built paths on Hera and WCOSS_DELL_P3 are provided here for reference.

3. setupRun.sh will setup the ROTDIR and copy a set of backgrounds from the previous cycle:

   • Set of example backgrounds (C96 resolution) initialized at 2019050100 (GDATE) can be used.

     $> setupRun.sh
     $> ls -1 $ROTDIR/gdas.20190501/00
     gdas.t00z.atmf000.nemsio
     gdas.t00z.atmf003.nemsio
     gdas.t00z.atmf006.nemsio
     gdas.t00z.atmf009.nemsio
     

   • A soft-link to the $ROTDIR and $RUNDIR will be placed in the experiment directory for easy access.

4. Grab an interactive compute node or submit the job to the queue. The script submitRun.sh set's up the runtime environment before the call to JGLOBAL_PREP:

   On Hera, to get an interactive node, use salloc. For submission use sbatch

   Interactive on Hera:
   heraFE$> salloc --partition=hera --qos=debug --account=fv3-cpu --nodes=1 --ntasks-per-node=4 --time=00:15:00 --chdir=$PWD --job-name=InteractiveJob
   $computeNode> submitRun.sh >& runLog.txt 2>&1
   

   Batch mode on Hera:
   heraFE$> sbatch --partition=hera --qos=debug --account=fv3-cpu --nodes=1 --ntasks-per-node=4 --time=00:15:00 --chdir=$PWD --job-name=JGLOBAL_PREP -e $PWD/runLog.txt -o $PWD/runLog.txt submitRun.sh
   

   On WCOSS Dell Phase 3 (Venus or Mars)

   Interactive mode on WCOSS_DELL_P3
   wcossP3FE$> bsub -Is -J InteractiveJob -P GFS-DEV -q debug -W 00:30 -n 4 -R 'span[ptile=4] affinity[core(1)]' -cwd $PWD bash
   $computeNode> submitRun.sh >& runLog.txt 2>&1
   

   Batch mode on WCOSS_DELL_P3
   wcossP3FE$> bsub -J JGLOBAL_PREP -P GFS-DEV -q debug -W 00:30 -n 4 -R 'span[ptile=4] affinity[core(1)]' -cwd $PWD -e $PWD/runLog.txt -o $PWD/runLog.txt < submitRun.sh
   

5. You are now ready to run this over and over and over.
