Petabyte-scale distributed storage systems are currently transitioning to erasure codes to achieve higher storage efficiency. Classical codes like reed-solomon are highly sub-optimal for distributed environments due to their high overhead in single-failure events. Locally Repairable Codes (LRCs) form a new family of codes that are repair efficient. In particular, LRCs minimize the number of nodes ...

Ever since the arrival of general purpose computers into the business environment, tension has existed between the departments who implement and manage the technology and those responsible for the business functions and processes. This struggle to integrate business and IT functions becomes increasingly important as technology becomes so entrenched in every facet of business operations ...

Chip Multi-Processors (CMPs) are the next attractive point in the design space of future high performance processors. There is a growing need for simulation methodologies to determine the memory system requirements of emerging workloads in a reasonable amount of time. To explore the design space of a CMP memory hierarchy, this paper presents the use ...
