Refactor GFS v16 workflow to reduce gdasanalcalc run time #85

Closed RussTreadon-NOAA closed 4 years ago

RussTreadon-NOAA commented 4 years ago

GFS v16 workflow ecen jobs require chgres'd gdas atmospheric forecasts from the previous cycle. This chgres operation is currently performed in current cycle gdasanalcalc. The chgres executable takes about 8 minutes to run on WCOSS_D. This chgres operation could be performed in the previous cycle, thereby allowing ecen to start 8 minutes earlier in the current cycle.

Cory made the necessary changes in global-workflow branch feature/chgresfcst. These changes require changes in GFS v16 DA. Cory made the DA changes in feature/gdaschgres, a branch in his fork of the NOAA-EMC/GSI repo.

This issue is opened to document these changes, their testing, and merger into global-workflow branch feature/gfsv16b.
