Outline

• The “geoscience” modelling workflow

• Inefficiencies

• The Solid Earth and Environment Grid

• The APAC (Geoscience) Grid

• Putting it all together: pmd*CRC Modelling Workflow

What is the role of:

• Competency contrasts?

• Permeability?

• Pore fluid pressure & flow fields?

Modelling Workflow

Define the geological problem

Build the model

Run the model

View and Interpret Results

Iterate to achieve Understanding

Report and feed into knowledge base

…Must be repeatable, robust and timely

Inefficiencies in the Workflow

Information is scattered across:

Organisations – company, geological survey, etc

Resources – different hardware and software platforms

Geography – geological surveys in each state and territory

Cost of data integration is high, in some situations exceeding all other costs

• Computational resources:

Different architectures suit different numerical codes better

Are often available but outside your organisations direct control

Are setup in different ways

Cost of adapting an investigators specific toolkit to use multiple sites is often prohibitive

Can these issues be removed?

The SEE Grid Community

Working together (loosely) to develop a toolkit for interoperability for the Solid Earth and Environmental Sciences

Together… because our information and services need to be shared more easily to achieve our goals

Loosely… because ultimately we are separated by political and economic boundaries

Toolkit… because our World is dynamic and we need tools that can be reconfigured and chained together quickly to answer our questions

…in this context we must reduce the barriers to becoming a part of the community

Traditional Mechanical Modelling Workflow

• “Powerful” desktop computes several models at a time

•Limitations are in the order of ~2 models per week.

• Models (mesh + data files) are individually and labouriously constructed

• The manual process is error prone

• Results are manually visualised one at a time.

• Screenshots are manually taken and made into “movies”.

• Very little, if any, standardised data archiving is done. This results in potential confusion or loss of the originating conditions of the experiments, making it unrepeatable in the long term.Slide courtesy of Robert Cheung and Warren Potma

18

New Refined Workflow

•Parameterised template or wizard driven model geometry/mesh creation.

•Boundary condition & model properties parameter sweep utilities

•automatically creates a “family” of model, data files based on varying a set of parameters.

• Inversion algorithms

•determine input parameters of future iterations automatically based on the user ranking of previous results.

Results to Date

For one Investigator, on one investigation:

•500 Models in 4 months (100x more!)

• Inversion/parameter sweep algorithms – semi-automated model creation; faster, less errors

• Automated post-processing/visualisation – all views X all timescale X all models await the investigator automatically

• Automated archiving – metadata searchable, more accurate store of experimental conditions, delivered to your store!

Conclusion

Major modelling inefficiencies have been removed by:

• Integrating the pmd*CRC geoscience modelling workflow

with the:

• Solid Earth and Environment Grid, and

• APAC (Geoscience) Grid
