HDF5 Acknowledgments

Supporters of HDF5

The HDF5 serial and parallel I/O library is the result of the collaboration of NCSA with three DOE laboratories: Lawrence Livermore National Laboratory (LLNL), Sandia National Laboratory (SNL) and Los Alamos National Laboratory (LANL). We would like to acknowledge the following people for their vision, support and technical contributions to this product since its inception.

Sponsors:

Judy Sturtevant (SNL) -: Judy has been a skilled and savvy manager of the project at SNL, helping to broaden the base of HDF5 use in exciting new directions at SNL, and playing a critical role in obtaining funding for the project. Judy has also made many valuable contributions to understanding tricky performance issues.
Greg Sjaardema (SNL) -: His technical leadership and support of a range of applications have been critical to the success of the project. He has shepherded SAF library development in recent years, taking it from a promising prototype to a powerful software product that important applications can rely on.
Linnea M. Cook (LLNL) -: Initiated the collaborative project, and has successfully shepherded its funding and sponsorship throughout the life of the project. Without Linnea's efforts, this project would not have happened.
Larry Schoof (SNL) -: Was one of the first supporters of the project. His sponsorship and astute technical advice were important to broadening the base of the collaborative effort and sustaining the project since the beginning.
Mark M. Miller (LLNL) -: His early support was essential to initiating this project. He contributed technically through his co-authorship of AIO, the LLNL I/O library adopted by NCSA as the prototype basis of HDF5, and also by a never-ending stream of ideas.
Celeste Matarazzo (LLNL) and Terri Quinn (LLNL) -: Provided funding during the crucial development stage, and continue to facilitate the project in many ways.
Jim Handrock (SNL) -: Provided funding to enable the project to thrive and expand at SNL.
Charles F. McMillan (LLNL) -: Provided the first funding for the project.
Philip Kegelmeyer, Mike Koszykowski and John Zepper (SNL) -: Provided funding during the crucial development stage.
Robert Gurule, John Ambrosiano, Bill Spangenberg, and Karl-Heinz Winkler (LANL) -: Provided sustaining funding before and after HDF5 became a product, and generated many good ideas for improving its utility.
Dan Reed (NCSA) -: Provided core funding for support of the NCSA HDF project at NCSA.
Richard Ullman and Ken McDonald (NASA ESDIS Project) -: Provide funding for HDF5 tools development, QA and prototyping.
Karen Moe (NASA Advanced Information Research Program) -: Provided funding for early research on feasibility of HDF5.

Technical Contributors:

Robb Matzke (LLNL) -: He designed and wrote much of the HDF5 library, utilities and documentation. He was the co-author of AIO, upon which much of HDF5 is based.
NCSA Team:

Mike Folk - Leads the HDF5 project at NCSA and contributed to the early design of HDF5.

Quincey Koziol - Together with Robb Matzke, led the design work for HDF5 and developed the library and documentation. Was a co-author of HDF4, the precursor to HDF5.

Albert Cheng - Led design and implementation of the parallel I/O in HDF5 using MPI-I/O, performance benchmarking and tuning. Was a co-author of HDF4.

Elena Pourmal - Manages the QA, maintenance, and user support efforts for HDF5. Implemented the Fortran 90 API for HDF5.

Barbara Jones - Provides HDF5 user support and tutorials, and maintains HDF5 website and ftp server.

Frank Baker - Manages, edits, and writes the HDF5 documentation (paper and web).

Bob McGrath and Peter Cao - Java tools and XML development for HDF5.

James Laird, John Mainzer, Binh-Minh Ribler, Ray Lu, Pedro Vicente Nunes, Bill Wendling, and Kent Yang - Library development
Jim Reuss (LLNL) -: Developed some of the earliest software to use HDF5, including DSL, a data structure layer that connects HDF5 to higher level libraries. Continues to provide valuable feedback.
Kim Yates, Pat Weidhaas, Richard Hedges and Tyce McLarty (LLNL) -: Worked with NCSA to implement parallel I/O in HDF5 using MPI-I/O, carried out performance benchmarking, corrected, and tuned the library, and ported the library to several LLNL platforms.
Tyce McClarty (LANL) -: Worked with NCSA to address parallel I/O requirements on ASCI Mountain Blue, now does the same at LLNL.
Thomas Radke and the CACTUS team (Albert Einstein Institute, Germany) -: Bleeding-edge user and innovator who has repeatedly demonstrated the utility of HDF5 for high performance applications.
John Ambrosiano (LANL) -: An early supporter, conceptualizer and tester within LANL.
Mike McKay (LANL) -: Implemented EnSight prototype and ardent supporter of HDF5.
Judy Sturdevent and Marty Barnaby (SNL) -: Maintain, benchmark and tune HDF5 on the Sandia ASCI machines.
Wilbur Johnson (SNL) -: Provided early support in designing and implementing the library to meet requirements on ASCI Red, and continues to work with HDF5 doing research on distributed access to ASCI data.
Dave Butler, John Blinka, Bill Arrighi (Limit Point Systems) -: As implementers of a large and complex application, the LPS team has provided valuable feedback on bugs and needed features.
Jerry Clark and the DICE team (Army Research Laboratory) -: An early and innovative user whose good ideas have driven HDF5 development in fruitful directions.
Rob Ross (Argonne National Laboratory) -: Integrated and benchmarked HDF with applications and the Parallel Virtual File System (PVFS), contributing valuable feedback for improving performance.
Michael Zingale and the FLASH team (University of Chicago) -: An early adopter, who continues to stress test the library and provide valuable feedback for improving the library and format.
Mike Krogh, Kent Misegades (CEI, Inc) -: Contributing to and encouraging API and standards to store unstructured grids in HDF5.

Technical Antecedents:

We would also like to credit I/O libraries from which we adopted good ideas:

HDF4 - NCSA's original multi-object scientific data file format. It provided many of the concepts, technologies, and lessons learned for developing HDF5.
AIO (LLNL) - Developed by Robb Matzke and Mark Miller. We selected the AIO technology as the basis for the development of HDF5.
PDBLib (LLNL) - Developed by Stewart Brown and Dennis Braddy. We adopted several ideas from this I/O library.
NetCDF - Developed at Unidata Program Center, provided good ideas for data model and library implementation.

Sustaining Funding:

The three DOE laboratories (Los Alamos National Laboratory, Sandia National Laboratory and Lawrence Livermore National Laboratory) have adopted HDF5 as the basis for their ASCI DMF I/O libraries. They are providing sustaining funding for maintenance, performance improvements, support and for moving HDF5 to their new parallel computers in the future.

NASA's ESDIS Project is providing sustaining funding for the HDF5 effort, with the goal of standardizing on HDF5 for future missions of the Global Change Research Program's Earth Observing System.
