Abstract :
Current and emerging large-scale HPC applications face daunting I/O challenges. In existing codes, problems arise both from large data volumes and from the need to perform complex online data manipulations, including data staging, reorganization, and transformation. We describe three related techniques for enabling, encouraging, and exploiting latent I/O asynchrony in HPC applications: data taps, IOgraphs, and Metabots.
