Extremophilic fungi can be harmful pathogens to humans. Slovenian researchers analysed their biology then used the same methods in their winning solution in data mining for the European Space Agency. They used the computer cluster 'SLING', the Slovenian Initiative for a National Grid, managed by ARNES, which comprises almost 20,000 kernels. The researchers also used the ARNES test cluster with as many as 4,460 kernels. With it, a team of researchers enabled the Mars Express probe to continue operating. In Slovenia, grid technology can be used by all researchers, since the ARNES test cluster is available to them. Grid users can quickly and easily perform very complex calculations. Research that would otherwise take several decades on a single computer, can be completed in a matter of days.
