Parallel data processing and parallel streaming systems become quite popular. They are employed in various domains such as real-time signal processing, OLAP database systems, or high performance data extraction. One of the key components of these systems is the task scheduler which plans and executes tasks spawned by the application on available CPU cores. The multiprocessor systems and CPU arc...

An increasing cache latency in next-generation processors incurs profound performance impacts in spite of advanced out-of-order execution techniques. One way to circumvent this cache latency problem is to predict load values at the onset of pipeline execution by exploiting either the load value locality or the address correlation of stores and loads. In this paper, we describe a new load value ...

The paper explores cache strategies for multimedia. Although many architectural improvements have been designed for multimedia, the cache structure and the standard caching policies of general-purpose processors exhibit poor performance in exploiting the 2D spatial locality typical of programs handling and processing images. In this paper we propose a novel caching approach suitably tailored to...

The dimensionality of the physical units as seen by an observer only capable of observations along the momentum axis is investigated. The units fall into seven groups characterized in terms of their ’frame signature’, mainly interpreted as non-locality and/or impact. For example, momentum, power, resistance, magnetic charge, and electric potential are related and have a direct impact on the loc...

The availability of massive healthcare data repositories calls for efficient tools for data-driven medicine. We introduce a distributed system for Stratified Locality Sensitive Hashing to perform fast similarity-based prediction on large medical waveform datasets. Our implementation, for an ICU use case, prioritizes latency over throughput and is targeted at a cloud environment. We demonstrate ...

A sensor node is composed of different parts including processing units, sensor, transmitter, receiver, and security unit. There are many nodes in a sensor unit. These networks can be used for military, industrial, medicine, environmental, house, and many other applications. These nodes may be established in the lands of enemies to monitor the relations. Hence, it is important to consider conse...

This paper presents code transformations designed to take advantage of the potential 2 orders of magnitude bandwidth increase available in a PIM-based architecture. Using an image processing application as a case study, we demonstrate how code transformations can exploit: (1) fine-grain parallelism in the wide-word processing unit to maximize the computation performed on each processor cycle; (...
