In data-intensive and multi-threaded programming, the performance bottleneck has shifted from I/O bandwidth to main memory bandwidth. The availability, size, and other properties of on-chip cache strongly influence performance. A key question is whether ...

Recent advances in solid state technology have led to the introduction of solid state drives (SSDs). Today's SSDs store data persistently using NAND flash memory and support good random IO performance. Current work in exploiting flash in database ...

The quest for real-time business intelligence requires executing mixed transaction and query processing workloads on the same current database state. However, as Harizopoulos et al. [6] showed for transactional processing, co-execution using classical ...

We present fpga-ToPSS (Toronto Publish/Subscribe System), an efficient event processing platform to support high-frequency and low-latency event matching. fpga-ToPSS is built over reconfigurable hardware---FPGAs---to achieve line-rate processing by ...

Compiling database queries into executable (sub-) programs provides substantial benefits comparing to traditional interpreted execution. Many of these benefits, such as reduced interpretation overhead, better instruction code locality, and providing ...

Energy consumption for computing devices in general and for data centers in particular is receiving increasingly high attention, both because of the increasing ubiquity of computing and also because of increasing energy prices. In this work, we propose ...

Increased energy costs and concerns for sustainability make the following question more relevant than ever: can we turn old or unused computing equipment into cost- and energy-efficient modules that can be readily repurposed? We believe the answer is ...
