Projects

ECP ExaHDF5: Independent HDF5 metadata update

In this ECP project, I'm working on building a serverless mechanism to maintain a consistent HDF5 namespace across participant processes. This will remove the limitation that applications must use collective operations to modify the namespace within an HDF5 file. 

EOD-HDF5: Advanced metadata and provenance management

I work on exploring strategies for capturing application metadata automatically when data is written to containers and for aggregating that metadata for collections of containers. I also conduct research on expanding the HDF5 interface to provide users with simpler ways to enter extensive metadata and provenance information through multiattribute interfaces and configuration files.
