Closing a Source Complexity Gap between Chapel and HPX

TL;DR

This paper explores reducing the source-code complexity gap between Chapel and HPX by using a source-to-source compiler, comparing their performance on Arm and x86 architectures.

Contribution

It introduces a source-to-source compiler approach to bridge the complexity gap between Chapel and HPX, with initial performance assessments.

Findings

Chapel and HPX show similar performance and complexity

Performance evaluated on Arm and x86 architectures

Initial results suggest potential for complexity reduction

Abstract

A previous case study measured performance vs source-code complexity across multiple languages. The case study identified Chapel and HPX provide similar performance and code complexity. This paper is the result of initial steps toward closing the source-code complexity gap between Chapel and HPX by using a source-to-source compiler. The investigation assesses the single-machine performance of both Chapel and Chplx applications across Arm and x86.
