Numerical experiments designed to simultaneously measure numerical reproducibility and sensitivity to
compiler optimization provide guidance for interpreting NWP research.
Topics discussed include context free grammars, recursive descent parsing, assembly language basics, JavaCC,
compiler optimization, and interpreters.

Compiler Optimization Techniques, A Technical White Paper, Wind River, www.windriver.com, 2005.
In this section, we distinguish our work from others that address alias analysis, method resolution, and
compiler optimization evaluation.
We begin our presentation with a review of background material related to
compiler optimization. Then, we describe a study of the application of compiler analysis to derive the three block algorithms in LAPACK considered above from their corresponding point algorithms.
Incorporating theory and practical examples without delving too deeply into specific languages and syntax, the volume covers such topics as multi-core architectures,
compiler optimization, parallel programming basics, node performance and accelerators.
Twenty-nine papers selected for the March 2006 symposium describe recent investigations on dynamic optimization, object-oriented code generation, phase detection and profiling, tiled and multicore compilation, and
compiler optimization. Working in both academia and industry, the researchers present a code cache-aware interface to the Pin dynamic instrumentation system, space-efficient 64-bit Java objects, and an automated profiling approach to identify code locations whose executions correlate with phase changes.
In the design and implementation of programming languages, analysis is critical to
compiler optimization and parallelization.
This could happen, for example, if the libraries are compiled using different compilers or
compiler optimization levels.
