Beschreibung

Technologies Storage systems have been regarded as a necessary, but mostly uninteresting component of high performance computers. Several trends are currently changing this role.
First of all, the amount of data written and read from hpc storage is increasing at an incredible speed even in the domain of traditional HPC. While, e.g., checkpointing has been a common, but feasible task in mid-sized cluster environments, it becomes extremely costly and frequent in multi-petabyte installations. A second trend is that several new data centric applications from the life science and physics domain appear and that HPC is widening its realm to include these applications from the field of big data and data analytics.
This new role of storage is reinforced by a widening performance gap between processors and traditional hard disks. This talk will cover several techniques to use existing HPC storage more efficiently and to include big data solutions within an HPC center as well as approaches to include new storage technologies, like flash and phase-change memory in the HPC stack.
