Emerging scale-out workloads require extensive amounts of computational resources. However, data centers using modern server hardware face physical constraints in space and power, limiting further expansion and calling for improvements in the computational density per server and in the per-operation energy. Continuing to improve the computational resources(More)
Recent research advocates large die-stacked DRAM caches in many core servers to break the memory latency and bandwidth wall. To realize their full potential, die-stacked DRAM caches necessitate low lookup latencies, high hit rates and the efficient use of off-chip bandwidth. Today's stacked DRAM cache designs fall into two categories based on the(More)
Fast access requirements preclude building L1 instruction caches large enough to capture the working set of server workloads. Efforts exist to mitigate limited L1 instruction cache capacity by relying on the stability and repetitiveness of the instruction stream to predict and prefetch future instruction blocks prior to their use. However, dynamic variation(More)
In server workloads, large instruction working sets result in high L1 instruction cache miss rates. Fast access requirements preclude large instruction caches that can accommodate the deep software stacks prevalent in server applications. Prefetching has been a promising approach to mitigate instruction-fetch stalls by relying on recurring instruction(More)
Introduced in 2007, TPC-E is the most recently standardized OLTP benchmark by TPC. Even though TPC-E has already been around for six years, it has not gained the popularity of its predecessor TPC-C: all the published results for TPC-E use a single database vendor's product. TPC-E is significantly different than its predecessors. Some of its distinguishing(More)

We describe our second-time participation, that includes one high-level feature extraction run, and three manual and one interactive search runs, to the TRECVID video retrieval evaluation. All of these runs have used a system trained on the common development collection. Only visual and textual information were used where visual information consisted of(More)
