Welcome to the C3 Digital Transformation Institute!

You have been given a grant as part of the new C3 Digital Transformation Institute (DTI)!
To make the start of your DTI experience as fast as possible, we have assembled a set of resources to

  1. Introduce researchers of all stripes to the C3 system
  2. Help researchers determine what level of training they will need to leverage C3's resources
  3. Point researchers directly to relevant documentation they will need
  4. Provide worked examples of different research workflows and how they may be ported into
    C3's environment, or may use C3's resources

If you have questions not covered by this guide, please contact the DTI team at the email help+c3ai@ncsa.illinois.edu

Introduction to the C3 system

C3 is a Java-based data analytics engine designed to make the ingestion and analysis of heterogeneous data sources
as painless as possible. The C3 system joins data from multiple sources into a single unified federated data image.
With the federated data image defined, C3 then provides an API to access that data, and in the case of time-series data,
perform numerous transformations and computations all producing normalized time-series data at regular intervals.

C3 also supports R and Python Jupyter notebook analysis of the federated data image. These notebooks provide a
great way for researchers to analyze data close to where the data is stored. While C3 supports many data science
capabilities familiar to the researcher, some expected functionality may be missing. For these cases, C3 supports
implementing new data processing functions in python and javascript.

Like any other API porting your own workflows will take some care and time to learn properly. Please leverage this guide
to make understanding C3's platform and porting your workflow as quick and easy as possible.

How do I get started?

Use this guide to determine what training you need to utilize C3's resources effectively. We have separated
researchers into four levels based on what level of interaction with C3's resources they require. We include
basic examples of workflows which might fall into that level, pros and cons of operating on that level, and
a list of training resources we recommend resources researchers completing on the DTI training environment
before starting their C3 allocations. This will ensure researchers will be able to use their allocation as
efficiently as possible.

Examine the high level overviews of each level below, then click the section titles to go to more in-depth
discussions related to that level, like the recommended training.

Level 1: Use COVID-19 Datalake Only

For many researchers, they will simply want to leverage the C3 COVID-19 Federated Data Image.



Level 2: GUI based data analysis on C3

C3 provides a wonderful GUI based interfaced to the C3 system with their Integrated Development Studio. Such
an environment is likely to be attractive to many researchers.



Level 3: Utilize C3 AI Suite and Jupyter notebook analysis

Some researchers will want to write their own C3 package and leverage more of the AI Suite through Jupyter notebooks.
C3 allows researchers to define their own types, methods, and use R and python to perform analysis on Datalake data.



Level 4: State-of-the-art ML workflows requiring special ML models and/or GPUs

Some researchers will want to bring state-of-the-art ML workflows to C3. C3 can support such workflows, but
extra work may be needed.



Accessing C3

This section introduces the process to access C3. Generally speaking, once you receive your grant,
the DTI team will reach out and discuss with you what your needs are.

  1. Determine which researchers will require access to a C3 tag.
  2. Each researcher will be given a C3.ai developer portal login.
  3. Each researcher will be given a tag on the C3.ai DTI training cluster.
  4. Once training is complete, Discuss with the DTI team what your needs
    for a C3 cluster will be.
  5. The C3.ai DTI will work with C3.ai to stand up a new tag for your research.
  6. Access to that tag will be granted to your researchers
  7. Research can then proceed until your allocation is exhausted!

Essential C3 Concepts

C3 is quite different from traditional HPC resources. We have written an introduction to C3 from the
perspective of a scientific researcher. We go over several important C3 concepts and relate them to
what scientists are more familiar with.

C3 Allocation Management

This section introduces How researchers will be expected to manage their allocation while on the C3 platform.

This section will be expanded once the DTI team understands how this procedure will look to the researcher.

Comprehensive List of Available Training and Resources

See the above link for a comprehensive list and categorization of the available training
materials. This includes C3 Documentation, DTI introductions, and DTI created examples and exercises.
