Kitagawa Data Engineering laboratory (Tsukuba, Japan) Performed research into XML query processing using GPGPU. Studied about low-level GPU features for general purpose computation, which involved extensive usage of the CUDA toolkit on both Windows 7 and GNU/Linux. Developed sharp debugging skills with this toolkit.
Excerpt of the abstract: The purpose of the research [..] is to evaluate the possibility of using General Purpose Graphic Processing Unit (GPGPU) to handle this task. GPGPU is a recent creation which gather research attention because of its large diffusion and cheap price. GPGPU is the result of the evolution of GPU coprocessors toward more flexibily and programable features in visual rendering. The latest features of these chips enable them to be used as stream processors.
Stream processing is a highly data parallalized task in which a series of operation is applied to each element of a data set (a stream).
Created a multiplatform datastructure for CUDA.
