A Classification of Scripting Systems for Entertainment and Serious Computer Games
The technology base for modern computer games is usually provided by a game engine. Many game engines have built-in dedicated scripting languages that allow the development of complete games that are built using those engines, as well as extensive modification of existing games through scripting alone. While some of these game engines implement proprietary languages, others use existing scripting systems that have been modified according to the game engine's requirements. Scripting languages generally provide a very high level of abstraction method for syntactically controlling the behaviour of their host applications and different types of scripting system allow different types of modification of their underlying host application. In this paper we propose a simple classification for scripting systems used in computer games for entertainment and serious purposes
PyCUDA and PyOpenCL: A Scripting-Based Approach to GPU Run-Time Code Generation
High-performance computing has recently seen a surge of interest in
heterogeneous systems, with an emphasis on modern Graphics Processing Units
(GPUs). These devices offer tremendous potential for performance and efficiency
in important large-scale applications of computational science. However,
exploiting this potential can be challenging, as one must adapt to the
specialized and rapidly evolving computing environment currently exhibited by
GPUs. One way of addressing this challenge is to embrace better techniques and
develop tools tailored to their needs. This article presents one simple
technique, GPU run-time code generation (RTCG), along with PyCUDA and PyOpenCL,
two open-source toolkits that support this technique.
In introducing PyCUDA and PyOpenCL, this article proposes the combination of
a dynamic, high-level scripting language with the massive performance of a GPU
as a compelling two-tiered computing platform, potentially offering significant
performance and productivity advantages over conventional single-tier, static
systems. The concept of RTCG is simple and easily implemented using existing,
robust infrastructure. Nonetheless it is powerful enough to support (and
encourage) the creation of custom application-specific tools by its users. The
premise of the paper is illustrated by a wide range of examples where the
technique has been applied with considerable success.Comment: Submitted to Parallel Computing, Elsevie
