We apply the notion of design patterns to optimizations performed by designers of software libraries, focusing especially on object-oriented numerical libraries. We formalize three design patterns that we have abstracted from many existing libraries and discuss the role of these formalizations as a tool for guiding compiler optimizers. These optimizers operate at a very high level that would ot...

Emoji usage drastically increased recently, they are becoming some of the most common ways to convey emotions and sentiments in social messaging applications. Several research works automatically recommend emojis, so users do not have go through a library thousands emojis. In order improve emoji recommendation, we present distribute two useful resources: an embedding model from real usage, clus...

In this work we present Lithium, a pure Java structured parallel programming environment based on skeletons (common, reusable and efficient parallelism exploitation patterns). Lithium is implemented as a Java package and represents both the first skeleton based programming environment in Java and the first complete skeleton based Java environment exploiting macro-data flow implementation techni...

Purpose – This research aims to integrate the unified theory of acceptance and usage of technology (UTAUT) with task technology fit to explain users’ behavioral intention of using library mobile applications in university libraries. Design/methodology/approach – By integrating the unified theory of acceptance and usage of technology (UTAUT) and the moderator of task-technology fit, this researc...

Most procedural programming languages, due to their restricted type systems, do not allow for polymorphic software components in the style of functional languages. Such polymorphism however greatly increases the potential for component reuse, while still guaranteeing the security of strong typing. In this paper, we show how to obtain polymorphic software components for “ordinary” languages like...

The limited communication bandwidth and high startup latencies of clustered workstations restrict their use to problems with sparse communication patterns or good concurrency between calculation and communication. First we describe our modiications to the popular PVMM5] message passing library, and on performance improvements using the PVM package on an FDDI-ring. Applications developed with a ...
