A publication on modeling HPC I/O workloads using a variety of workload sources, including Darshan logs, has been accepted at PMBS 2015. This work utilizes the CODES exascale storage system simulation toolkit to analyze the merits of using distinct workload sources (I/O traces, synthetic I/O descriptions, and Darshan I/O characterizations) as input to storage system simulations, as well as replays of I/O workloads on real HPC systems. Documentation on how to configure the CODES workload generator to use Darshan logs as input is given in the CODES repository.
This post will be updated with a link to the paper once the final version is made available online.
