MAP-numa: Access Patterns Used to Characterize the NUMA Memory Access Optimization Techniques and Algorithms

Some typical memory access patterns are provided and programmed in C, which can be used as benchmark to characterize the various techniques and algorithms aim to improve the performance of NUMA memory access. These access patterns, called MAP-numa (Memory Access Patterns for NUMA), currently include three classes, whose working data sets are corresponding to 1-dimension array, 2-dimension matri...

An Overview of Non-Uniform Parameterized Complexity

We consider several non-uniform variants of parameterized complexity classes that have been considered in the literature. We do so in a homogenous notation, allowing a clear comparison of the various variants. Additionally, we consider some novel (non-uniform) parameterized complexity classes that come up in the framework of parameterized knowledge compilation. We provide some (inclusion and se...

Segmented Bitline Cache: Exploiting Non-uniform Memory Access Patterns

On chip caches in modern processors account for a sizable fraction of the dynamic and leakage power. Much of this power is wasted, required only because the memory cells farthest from the sense amplifiers in the cache must discharge a large capacitance on the bitlines. We reduce this capacitance by segmenting the memory cells along the bitlines, and turning off the segmenters to reduce the over...

Visualizing the Memory Access Behavior of Shared Memory Applications on NUMA Architectures

Data locality is one of the most important issues affecting the performance of shared memory applications on NUMA architectures. A possibility to improve data locality is the specification of a correct data layout within the source code. This kind of optimization, however, requires in depth knowledge about the run-time memory access behavior of programs. In order to acquire this knowledge witho...

Exploiting Hidden Non-uniformity of Uniform Memory Access on Manycore CPUs

As the rate of CPU clock improvement has stalled for the last decade, increased use of parallelism in the form of multiand many-core processors has been chased to improve overall performance. Current highend manycore CPUs already accommodate up to hundreds of processing cores. At the same time, these architectures come with complex on-chip networks for inter-core communication and multiple memo...
