In Call the Doctor on Tuesday, March 21st, Chief HDF5 Software Architect Neil Fortner subbed in to talk about The HDF Group’s work on the HDF5 multiple dataset APIs and highlight the performance benefits when using them.
The HDF5 library allows a data access operation to access one dataset at a time. However, accessing multiple datasets requires the user to issue an I/O call for each dataset. Hence, the new multiple dataset APIs allow users to access multiple datasets with a single I/O call. In addition, the new routines can improve performance, especially when data is accessed across several datasets from all processes.

Call the Doctor is a series of weekly, unscripted, live events! The HDF Group’s staff members will answer attendee questions and, for example, go over the previous week’s HDF Forum posts. The HDF Clinics are free sessions intended to help users tackle real-world HDF problems from a common cold to severe headaches and offer relief where that’s possible. As time permits, we will include how-tos, offer advice on tool usage, review your code samples, teach you survival in the documentation jungle, and discuss what’s new or just around the corner in the land of HDF.
Join us every Tuesday at 12:20 p.m. central (US/Canada.) on Zoom!
