Computational Computer Science  Zero introduces students to the basics of programming through multimedia, and then uses these programming techniques to examine basic functions that draw lines and curves. At the end of the course students use these same techniques to explore the principles underlying familiar physical processes. Computational CSZero uses easily taught and adaptable programming concepts as a framework for modeling the behavior of physical objects. The course reinforces the concepts and intuitions of precalculus and mathematical modeling by engaging students in handson simulations of physical systems. Computational CSZero teaches the foundations of programming while promoting mathematical competence necessary for academic success. Computational CSZero is sponsored by NSF's CCLI program and is a participant in the Computing Alliance of Hispanic Serving Institutions.

Summary:

[Expand Summary]
This thesis describes how to compute the fast Fourier transform (FFT) of a poweroftwo length signal on singleinstruction, multipledata (SIMD) microprocessors faster than or very close to the speed of state of the art libraries such as FFTW (``Fastest Fourier Transform in the West''), SPIRAL and Intel Integrated Performance Primitives (IPP). The conjugatepair algorithm has advantages in terms of memory bandwidth, and three implementations of this algorithm, which incorporate latency and spatial locality optimizations, are automatically vectorized at the algorithm level of abstraction. Performance results on 2way, 4way and 8way SIMD machines show that the performance scales much better than FFTW or SPIRAL. The implementations presented in this thesis are compiled into a highperformance FFT library called SFFT (``Streaming Fast Fourier Transform''), and benchmarked against FFTW, SPIRAL, Intel IPP and Apple Accelerate on sixteen x86 machines and two ARM NEON machines, and shown to be, in many cases, faster than these state of the art libraries, but without having to perform extensive machine specific calibration, thus demonstrating that there are good heuristics for predicting the performance of the FFT on SIMD microprocessors (i.e., the need for empirical optimization may be overstated).
