HPC Storage is arguably one of the most pressing issues in HPC. Selecting various HPC Storage solutions is a problem that requires some research, study, and planning to be effective – particularly cost-effective. Getting this process started usually means understanding how your applications perform I/O.

I recently wrote a detailed article that presents some techniques for examining I/O patterns in HPC applications. The story called, HPC Storage - Getting Started with I/O Profiling, reviews different ways you can measure the performance of storage system used in HPC, as well as the applications used. My goal is to share some ideas about how to analyze your I/O needs from the perspective of an application.
