Job Runtime

  • Depends on how many SLCs are being processed

  • 1+ hours for 8 SLCs

GNU Parallel


c5d.9xlarge

(36 vCPU, 72 GiB)

c5.24xlarge

(96 vCPU, 192 GiB)

1 year (~30 SLCS, 4 bursts)

7 hrs, 24 mins, 46 secs

4 hrs, 38 mins, 33 secs

2 year (~60 SLCS, 4 bursts)

13 hrs, 37 mins, 39 secs

8 hrs, 16 min, 46 secs

Objective

Creating a stack of SLCs

  • Only within the same track (over a time period)

Prerequisite to STAMPS processing

How to set up the inputs

  • Facets to get SLC inputs

    • region (ex. Hawaii) (optional)

    • track_number or trackNumber (depends)

    • datatype: SLC

If SLCs track number do not match, then it would throw this error in the job:

  • Code Block
    raise  Exception('Could not determine a suitable burst offset')

  • There must only be one track in your SLC inputs

correct facet SLC inputs incorrect facet SLC inputs

...

Job Inputs:

  • Bbox (*required)

    • min_lat max_lat min_lon max_lon

Main file that gets executed is run_stack.sh

  • Copies all SLCs .zip files to zip/ sub-directory

  • runs get_bbox.py and exports 8 coordinates as inputs for the science code

    • read MINLAT MAXLAT MINLON MAXLON MINLAT_LO MAXLAT_HI MINLON_LO MAXLON_HI <<< $TOKENS

  • Runs 10 steps to complete the stack processor

Running on ASG (Auto Scaling Group)

  • Currently using c5d.9xlarge

    • Not enough CPU

    • Takes 11.5 Hrs to run 30 scenes

  • May need to upgrade to c5d.18xlarge or i-instances

...

STILL TODO:

  • Integrate Sang-Ho/Jungkyo GNU parallel
