Modern software packages have become increasingly complex with millions of lines of code
and references to many external libraries. Redundant operations are a common …

Complex code bases with several layers of abstractions have abundant inefficiencies that
affect the execution time. Value redundancy is a kind of inefficiency where the same values …

Compilers are an indispensable component in the software stack. Besides generating
machine code, compilers perform multiple optimizations to improve code performance …

In this paper, we propose a runtime framework that implements code multi-versioning and
specialization to optimize and parallelize loop kernels that are invoked many times with …

Dynamic scripting languages are becoming more and more widely adopted not only for fast
prototyping but also for developing production-grade applications. They provide high …

Computational scientists are typically not expert programmers, and thus work in easy to use
dynamic languages. However, they have very high performance requirements, due to their …

Computer programs commonly repeat work. Short programs go through the same
initialisation sequence each time they are run, and long-running servers may be given a …

Function merging is a pivotal technique for reducing code size by combining identical or
similar functions into a single function. While prior research has extensively explored this …

This article considers automatic performance tuning of time-step-based parallel solution
methods for initial value problems (IVPs) of systems of ordinary differential equations …

Interpreters are widely used to implement high-level language virtual machines (VMs),
especially on resource-constrained embedded platforms. Many scripting languages employ …
