|Abstract||While supercomputers continue to deliver increasingly greater computational power, the associated storage systems lag behind in terms of available bandwidth. Supercomputer architects have designed more complex storage hierarchies to bridge the storage-CPU performance gap. These storage hierarchies include solid-state drives (SSDs) and nonvolatile memory (NVM), either local to a compute node or hosted on an intermediate proxy node. While these technologies offer new opportunities for performance improvements, they also pose a challenge: applications need a way to discover what, if any, storage hierarchy is in place.
