Abstract
Summary
a new and novel dynamic approach for writers selection by mapping writing tasks dynamically and adaptively to MPI processes at runtime. The objective of this method is not to deduce the optimal number of writers that should be used. Instead, the method determines and recommends better mapping that enhances the balance of I/O workload across hosts and maximize the overall I/O performance during the lifespan of the simulation run.
