Guidelines
The continuously increasing amounts of unstructured data also emphasize the need for effective means of extracting relevant information from these data, so the data are ready for the subsequent machine processing (e.g., storing the data in structured form or performing search queries). Some of these data mining problems can be solved by cluster analysis. It classifies given objects into groups based on selected features. The formed groups gather objects, which are considered similar in the terms of recognized characteristics. Unfortunately, the clustering process is rather time-consuming; therefore, it may be virtually useless for very large data collections.

One of the possible solutions is to parallelize the cluster analysis. A parallel implementation can take advantages of the current processor architectures that integrate multiple processing cores into a single chip. It may also be possible to utilize specialized computational accelerators that have become economically attractive even for ordinary users. For example, new graphics cards are capable of processing thousands computational threads concurrently, whilst these threads can cooperate on quite generic computational tasks.

The main objective of this work is the analysis of the clustering algorithms in the perspective of massively parallel processing on specialized computing devices, especially on the graphics cards. The project will also require design and implementation of several prototype solutions. These prototypes will be experimentally evaluated to asses the applicability of different approaches for various configurations of cluster analysis and for different data sizes.
