Applications

These applications were ported and deployed on XtremWeb-CH:

Cyclone Track Cyclone Track is an application for predicting tracks and effects of cyclones. It has been developed by the Enviro GRIDS group at the University of Geneva. CYCLONE evaluates the impact of cyclones on the environment using a parallel simulation. MUSIC considerably improved the analysis: it is now possible to analyse 800 cyclones
in 1 hour 20 minutes, whereas previously only 50 cyclones could be analysed in that time.
Selector Selector is an application for simulating people’s migrations in East Asia. By Laboratory of Anthropology, Genetics and Peopling History, University of Geneva. SELECTOR estimates the migration of people in East Asia on the basis of genetic data. It is used in testing two competing hypothesis: 1. The populations of South and North East Asia originate from just one population; 2. Tey originate from two different populations. Testing the hypothesis requires between 100,000 and 1,000,000 simulations for each hypothesis.
This would take 100-200 days on a single PC. On XtremWeb-CH, the run time for the simulation was cut to just a couple of days.
Metapiga.jpg MetaPIGA is a robust implementation of several stochastic heuristics for large phylogeny inference (under maximum likelihood), including a simulated annealing algorithm, a classical genetic algorithm, and the metapopulation genetic algorithm (metaGA) together with complex substitution models, discrete Gamma rate heterogeneity, and the possibility to partition data. MetaPIGA also implements the Likelihood Ratio Test, the Akaike Information Criterion, and the Bayesian Information Criterion for automated selection of substitution models that best fit the data. Heuristics and substitution models are highly customizable through manual batch files and command line processing.
Medgift.jpg Gift, or Gnu Image Finding Tool, software is a content-based image indexing and retrieval package. GIFT utilizes techniques common from textual information retrieval and uses a very large collection of binary-valued features (global and local colour and texture features). GIFT extract these features and stores them in an inverted file. These images are currently being used in medicine (diagnostic aid in hospitals) and art (classifying drawings).
Neurad.jpg The Neurad project involves medical physicists and computer scientists whose goal is to enhance the treatment planning of cancerous tumors by external radiotherapy. The Neurad software provides a fast and accurate evaluation of radiation doses in any given environment (possibly inhomogeneous) for given irradiation parameters.
Neuroweb.jpg The NeuroWeb application builds neuronal maps of brain activities with non-invasive measurements. The goal is to localize brain areas (group of neurons) responsible of a given dysfunction (epileptic crisis, Parkinson, Alzheimer, etc). Once these regions are localized, they can be removed by surgery. The neuronal map extracted from brain measurements and calculated with the NeuroWeb software is integrated into the NeoBrain software to visualize the spatial and temporal brain activity in 3D stereo world.
