Leveraging WebAssembly for Numerical JavaScript Code Virtualization

WebAssembly and JavaScript Challenge: Numerical program performance using modern browser technologies and devices

Recent advances in execution environments for JavaScript and WebAssembly that run on a broad range of devices, from workstations to IoT devices, provides new opportunities for portable and web-based numerical computing. The aim of this paper is to evaluate the current state of the art through a comprehensive experiment using the Ostrich benchmark suite, a collection of numerical programs repres...

JSZap: Compressing JavaScript Code

JavaScript is widely used in web-based applications, and gigabytes of JavaScript code are transmitted over the Internet every day. Current efforts to compress JavaScript to reduce network delays and server bandwidth requirements rely on syntactic changes to the source code and content encoding using gzip. In this paper, we consider reducing the JavaScript source code to a compressed abstract sy...

Fission: Secure Dynamic Code-Splitting for JavaScript

Traditional web programming involves the creation of two distinct programs: a client-side frontend, a server-side back-end, and a lot of communications boilerplate. An alternative approach is to use a tierless programming model, where a single program describes the behavior of both the client and the server, and the runtime system takes care of communication. Unfortunately, this usually entails...

Opportunities for Leveraging OS Virtualization in High-End Supercomputing

This paper examines potential motivations for incorporating virtualization support in the system software stacks of highend capability supercomputers. We advocate that this will increase the flexibility of these platforms significantly and enable new capabilities that are not possible with current fixed software stacks. Our results indicate that compute, virtual memory, and I/O virtualization o...
