PLFS Testing on Chinook


EMSL Project ID
36395

Abstract

Many HPC Applications do periodic checkpointing to save state after each itteration of a simulation. Sometimes the scientific application creates I/O patterns that do not fit Chinook very well. In an effort to discover better ways to streamline the I/O for our scientific applications we need to investigate PLFS to allow scientific applications to checkpoint faster. We would like to test several applications to see if PLFS has the ability to help speed up checkpointing of the scientific applications we use. Chinook has some of the fastest disk in the world if we see any improvement we should be able to see it here.
