The processing of graph data at large scale, though important and useful for real-world applications, continues to be challenging, particularly for problems such as graph partitioning. Optimal graph partitioning is NP-hard, but several methods provide approximate solutions in reasonable time. Yet scaling these approximate algorithms is also challenging. In this paper, we describe our efforts towards...
Cloud and data center applications often make heavy use of virtualized servers, where flash-based solid-state drives (SSDs) have become popular alternatives over hard drives for data-intensive applications. Traditional data prefetching focuses on applications running on bare metal systems using hard drives. In contrast, virtualized systems using SSDs present different challenges for data prefetching...
While hard drives hold on to the capacity advantage, flash-based solid-state drives (SSD) with high bandwidth and low latency have become good alternatives for I/O-intensive applications. Traditional data prefetching has been primarily designed to improve I/O performance on hard drives. The same techniques, if applied unchanged on flash drives, are likely to either fail to fully utilize SSDs, or interfere...
