Near-Data Filters: Taking Another Brick from the Memory Wall

Diego G. Tomé, Tiago Rodrigo Kepe, Marco A. Z. Alves, Eduardo Cunha de Almeida
2018 Very Large Data Bases Conference  
In this paper, we use the potential of the near-data parallel computing presented in the Hybrid Memory Cube (HMC) to process near-data query filters and mitigate the data movement through the memory hierarchy  ...  Our near-data filters support vector instructions and solve data and control dependencies internally in the memory: internal register bank and branch-less evaluation of data filters transform control-flow  ...  However, in-memory query processing suffers from the interconnection and cache latency required to move large amounts of data around the memory and cache hierarchy (i.e., hit the "memory wall").  ...

Hash-Based Hierarchical Caching and Layered Filtering for Interactive Previews in Global Illumination Rendering

Thorsten Roth, Martin Weier, Pablo Bauszat, André Hinkenjann, Yongmin Li
2020 Computers  
Modern Monte-Carlo-based rendering systems still suffer from the computational complexity involved in the generation of noise-free images, making it challenging to synthesize interactive previews.  ...  Our approach allows for memory-efficient storage and constant-time lookup to cache diffuse illumination at multiple hitpoints along the traced paths.  ...  Data memory is the amount of memory required to store the full data arrays. Hash memory is the amount of memory reserved for the hash map representation for the respective level.  ...

P and M Class Phasor Measurement Unit Algorithms Using Adaptive Cascaded Filters

A. J. Roscoe, I. F. Abdulhadi, G. M. Burt
2013 IEEE Transactions on Power Delivery  
This is particularly the case at offnominal frequencies under the influence of harmonic content, since any unwanted signals emerging from the filters will impart ripple onto the measured signal phase.  ...  filtering is altered, rather than preadjusting the samples or post-adjusting the measured values.  ...  This is achieved using a Butterworthstyle "brick wall" filter.  ...

2019 Linguistic Landscape  
Aligned with recent work on affect and people's mediations of the linguistic landscape (Wee, 2016; Banda & Jimaima, 2015), I examine how the Mission is filtered – literally and figuratively – in a corpus  ...  As mining of 'big data' becomes increasingly valued as empirically 'objective' information, my analysis demonstrates geotagged content should not be viewed as a static indicator, but as a subjective, dynamic  ...  Along the eastern edge of the valley, another wall was built from Mission Creek to Precita Creek, across the neck of the peninsula that is now Potrero Hill, but then was called potrero nuevo, or new pasture  ...
