Scientific applications from many problem domains produce and/or access large volumes of data. To support these applications, designers of high-end computing (HEC) systems have greatly increased the capacity of storage systems in recent years. However, because hard disk drives (HDDs) are still the dominant storage device used in HEC storage systems, and because HDD performance has not improved as...
Flash-memory based Solid State Drives (SSDs) embrace higher performance and lower power consumption compared to traditional storage devices (HDDs). These benefits are needed in HPC systems, especially with the growing demand of supporting Big Data applications. In this paper, we study placement and deployment strategies of SSDs in HPC systems to maximize the performance improvement, given a practical...
High-end computing (HEC) applications and simulations have become increasingly data intensive. The pressure on the storage system capability has substantially increased in recent years. Traditional hard disk drives (HDD) are dominant storage devices in HEC, but suffer seek time delays and rotational latencies. The emerged storage class memory such as Solid State Drive (SSD) provides a new promising...
