    Description: SZTAKI Desktop Grid has been set up by the Computer and Automation Research Institute of the Hungarian Academy of Sciences (MTA). Desktop grids allow vast number of single PCs to be connected in a grid-like system, adding up their processing power. Desktop grid systems are currently serving several cutting edge research areas, like cancer research or climate change.

    SzDG is an online architecture, run by the Laboratory of Parallel and Distributed Systems. The staff of the laboratory maintains the system, which is open for any scientific research seeking immense computing power. SzDG currently hosts one mathematical project. The program aims at finding many generalized binary number systems. An extensive search is performed in the finite set of matrices of given size fulfilling some necessary conditions. The difficulty is that the size of this finite set is an exponential function of the dimension. It now seems possible to attack the case of 11 ◊ 11 matrices. To check further necessary conditions the program performs a lot of floating-point calculation. Thus, a lot of CPU time is needed. Luckily, parallelization is possible, so the project can benefit from running on multiple machines.

    The program outputs a list of matrices (to be more precise, their characteristic polynomials) that are already likely to be number system bases. This list is processed by another program (which does not need so much CPU-time). The final result is then a (complete) list of binary number systems in a fixed dimension.

    In beta phase, the project started by investigating the 10th dimension, which entailed the processing of ninety thousand matrices, of which a total of 383 pieces seemed to be worthy of further inspection.
