The HDF Group’s HDF Server has been nominated for Best Use of HPC in the Cloud, and Best HPC Software Product or Technology in HPCWire’s 2016  Readers’ Choice Awards. HDF Server is a Python-based web service that enables full read/write web access to HDF data – it can be used to send and receive HDF5 data using an HTTP-based REST interface. While HDF5 provides powerful scalability and speed for complex datasets of all sizes, many HDF5 data sets used in HPC environments are extremely large and cannot easily be downloaded or moved across the internet to access data on an as-needed basis.  Users often only need to access a small subset of the data.  Using HDF Server, data can be kept in one...

David Pearah, The HDF Group Hello HDF Community! Thanks for the warm welcome into the HDF family: in my 4+ months as the new CEO, I've been blown away by your passion, diversity of interests and applications, and willingness to provide feedback on:  1. why you use HDF5?, and  2. how can HDF5 be improved? I also want to thank my predecessor Mike Folk for his invaluable and ongoing support. The HDF community is growing fast: when I last checked, there are nearly 700 HDF5 projects in GitHub! I've had the privilege of connecting via phone/web with dozens of you over the past few months. Across all of my discussions, one piece of feedback came back loud and clear: The HDF Group needs to be more engaged with its users and help foster...

Perhaps the original producers of “big data,” the oil & gas (O&G) industry held its eighth annual High-Performance Computing (HPC) workshop in early March. Hosted by Rice University, the workshop brings in attendees from both the HPC and petroleum industries.

Jan Odegard, the workshop organizer, invited me to the workshop to give a tutorial and short update on HDF5.

The workshop (#oghpc) has grown a great deal during the last few years and now has more than 500 people attending, with preliminary attendance numbers for this year’s workshop over 575 people (even in a “down” year for the industry).  In fact, Jan’s pushing it to a “conference” next year, saying, “any workshop with more attendees than Congress is really a conference.” But it’s still a small enough crowd and venue that most people know each other well, both on the Oil & Gas and HPC sides.

The workshop program had two main tracks, one on HPC-oriented technologies that support the industry, and one on oil & gas technologies and how they can leverage HPC.  The HPC track is interesting, but mostly “practical” and not research-oriented, unlike, for example, the SC technical track. The oil & gas track seems more research-focused, in ways that can enable the industry to be more productive.

I gave an hour and a half tutorial on developing and tuning parallel HDF5 applications, which

The HDF Group’s mission is to provide high quality software for managing large complex data, to provide outstanding services for users of these technologies, and to insure effective management of data throughout the data life cycle....
