CIB Vision
CIB seeks to: o Develop/improve models through a more
efficient “open” model development and validation process
o Open climate/Earth science model development and validation to a community beyond traditional domain scientists
![Page 6: Climate-in-a-Box (CIB) Workshop: Introduction and Overview · Introduction and Overview Gary Wojcik Northrop Grumman Corporation Software Integration and Visualization Office (SIVO)](https://reader034.fdocuments.us/reader034/viewer/2022051917/6008d1c6bd2c146af813098e/html5/thumbnails/6.jpg)
CIB Motivations
NASA/NOAA climate/earth science models are difficult to use o Can be challenging for domain experts o Non-typical users (e.g., non-domain
scientists, policymakers) may want to run models
![Page 7: Climate-in-a-Box (CIB) Workshop: Introduction and Overview · Introduction and Overview Gary Wojcik Northrop Grumman Corporation Software Integration and Visualization Office (SIVO)](https://reader034.fdocuments.us/reader034/viewer/2022051917/6008d1c6bd2c146af813098e/html5/thumbnails/7.jpg)
CIB Motivations
Supercomputing resources are not always readily accessible o Wait times in job queues can be extensive o Arduous application process for foreign
nationals
![Page 8: Climate-in-a-Box (CIB) Workshop: Introduction and Overview · Introduction and Overview Gary Wojcik Northrop Grumman Corporation Software Integration and Visualization Office (SIVO)](https://reader034.fdocuments.us/reader034/viewer/2022051917/6008d1c6bd2c146af813098e/html5/thumbnails/8.jpg)
CIB Goals
Make NASA/NOAA climate/earth science models more accessible
Explore desktop supercomputing architectures
Package models and support software as a “toolkit” for desktop supercomputers
Explore use of the system for “open” model development/validation

CIB Stages
Port models to architectures other than typical supercomputers o Explore desktop architectures o Develop model process management tools
Develop automated software management system
Explore virtualization

Workflow Tool Simplifies/Automates
model execution management and other processes
Provides common look and feel between models and between systems
Allows for experiment sharing and repeatability
![Page 15: Climate-in-a-Box (CIB) Workshop: Introduction and Overview · Introduction and Overview Gary Wojcik Northrop Grumman Corporation Software Integration and Visualization Office (SIVO)](https://reader034.fdocuments.us/reader034/viewer/2022051917/6008d1c6bd2c146af813098e/html5/thumbnails/15.jpg)
Workflow “Switch” Capability Enable model execution to be as seamless as
possible between CIB and larger cluster or other CIBs o Large HPC systems can be used for validation and
simulations at a higher resolution Data movement through workflow or shared/
open resource Virtualization: explore a virtual image that can
be moved from CIB to larger cluster or other CIBs
