- Automatic implementation of evolutionary algorithms on GPUs using ESDL
- Dower, Steve
- Modern computer processing units lend towards simpler cores in greater numbers, favouring the development of data-parallel applications. Evolutionary algorithms are ideal for taking full advantage of SIMD (Single Instruction, Multiple Data) processing, which is available on both CPUs and GPUs. Creating software that runs on a CPU requires the use of specialised programming languages or styles, forcing practitioners to acquire new skills and limiting the portability of their developments. In this paper, we present an automatic translation from ESOL, a domain-specific language for composing evolutionary algorithms from arbitrary operators, to C++ AMP, a C++ extension for targeting heterogeneous hardware. Generating executable code from a simple platform-independent description allows practitioners with varying levels of programming expertise to take advantage of data-parallel execution, and enables those with strong expertise to further optimise their implementations. The automatic transformation is shown to produce code less optimal than a manual implementation but with significantly less developer effort. A secondary result is that GPU implementations require a large population, large individuals or an expensive evaluation function to achieve performance benefits over the CPU.
