Scientific Data Use Cases

Today's research increasingly relies on generating, collecting, organizing, and analyzing large amounts of data. Researchers often find themselves needing to work with more data than personal or laboratory computers are equipped to handle, and in some cases, the same scales used by large corporations and government agencies. XSEDE helps researchers meet these challenges both by providing access to resources that are specialized to work with data, and by providing services that make data analysis, data management, and data sharing possible for small teams.

 

Data Analysis:

These use cases describe how scientists analyze large amounts of scientific data using XSEDE resources and services. The data is typically large in volume (larger than one would use on a personal or business computer), but is organized and stored in different ways for different kinds of research. Data might be generated by a single source (a large simulation, for example) or it might come from many sources (observational results from many different instruments or different research teams). The methods of analysis also vary from field to field and problem to problem.

DA-02 Data preparation
DA-03 Instrument data analysis
DA-04 HPC simulation data analysis
DA-05 In situ computational steering

 

Data Management:

These use cases describe how researchers manage collections of data for shared use or for their own re-use over time. The use cases range from a single research project managing and organizing its own data, to several related projects using each other's data, or to data being prepared for future use in applications that haven't been imagined yet.

Visualization:

These are the most common scientific data visualization methods among people using XSEDE resources. This is an evolving field of work, since the ability of desktop computers to visualize data is improving rapidly. Nevertheless, it is still not unusual for researchers to need to visualize data at scales that exceed their local resources, requiring them to use XSEDE resources to advance their work.
