Scaling up Superoptimization

Superoptimization in LLVM

Superoptimization is a known technique to integrate the analyses and transformations of a number of separate optimizations in order to obtain an optimization that is more expressive than the sequential and iterative application of the original optimizations. This paper describes the elaboration of this technique within the Low Level Virtual Machine (LLVM) Compiler Infrastructure. A framework su...

Scaling Up

Most analytical and experimental results on evolutionary programming (EP) are obtained using low-dimensional problems, e.g., smaller than 50. It is unclear, however, whether the empirical results obtained from the low-dimensional problems still hold for high-dimensional cases. This paper investigates the behaviour of four diierent EP algorithms for large-scale problems, i.e., problems whose dim...

Scaling - Up or Out

Insatiable demands for performance and the availability of inexpensive microprocessors have led to the development of multiprocessor-based systems. Passionate debates amongst architects, designers, and vendors continue to rage regarding cost effective multiprocessor design alternatives. Hypes and claims of performance and scalability are confusing and often misleading. Increasing performance an...

Scaling up co-design

In this paper we reflect on our experiences in a project where academic researchers and social change organizations are working together to explore how participatory and co-design practices can be disseminated and spread within the ‘third sector’. The research project is itself co-designed and co-produced, but within various constraints arising from research funding models. We explore both our ...
