Chip multicore processors (CMPs) have emerged as the dominant architecture choice for
modern computing platforms and will most likely continue to be dominant well into the …

Architectural simulation is time-consuming, and the trend towards hundreds of cores is
making sequential simulation even slower. Existing parallel simulation techniques either …

Scaling the performance of short TCP connections on multicore systems is fundamentally
challenging. Although many proposals have attempted to address various shortcomings …

Commodity computer systems contain more and more processor cores and exhibit
increasingly diverse architectural tradeoffs, including memory hierarchies, interconnects …

We present PacketShader, a high-performance software router framework for general packet
processing with Graphics Processing Unit (GPU) acceleration. PacketShader exploits the …

Industry is building larger, more complex, manycore processors on the back of strong
institutional knowledge, but academic projects face difficulties in replicating that scale. To …

NUMA systems are characterized by Non-Uniform Memory Access times, where accessing
data in a remote node takes longer than a local access. NUMA hardware has been built …

Rapid growth of the demand for computational power has led to the creation of large-scale
data centers. They consume enormous amounts of electrical power resulting in high …

This paper analyzes the scalability of seven system applications (Exim, memcached,
Apache, PostgreSQL, gmake, Psearchy, and MapReduce) running on Linux on a 48-core …

This paper presents the most exhaustive study of synchronization to date. We span multiple
layers, from hardware cache-coherence protocols up to high-level concurrent software. We …
