ROMIO at SC 2019

by Latham, Robert J.

We wrapped up another SC week in Denver .

  • Saw a good bit of interest in ROMIO features, performance, and supported drivers at our I/O tutorial Parallel I/O in Practice
  • I’m excited about some of the new features discussed at the HDF5 BoF, including an “everyone reads the same data” optimization that was a tremendous pain to implement in ROMIO, but (with a bit of additional communication) easy to implement at the HDF5 layer
