Description du projet<\/h3>\n

Alors que la puissance de calcul disponible en science ne cesse de cro\u00eetre et que les m\u00e9thodes num\u00e9riques et les algorithmes d’analyse de donn\u00e9es sont de plus en plus performants, les codes en sciences computationnelles ne cessent de gagner en complexit\u00e9. Le projet GULI, gr\u00e2ce \u00e0 la collaboration entre le LAPP et le LAMA, vise \u00e0 concevoir une solution au probl\u00e8me de grandeurs et d\u2019unit\u00e9s au travers d’une approche interdisciplinaire m\u00ealant physique,
\nmath\u00e9matiques, et informatique. Au lieu d’essayer d’impl\u00e9menter une solution logicielle partielle puis d’essayer de l’\u00e9tendre \u00e0 des cas d’applications de plus en plus exotiques, l’id\u00e9e centrale du projet va consister \u00e0 commencer par se concentrer sur l’\u00e9tude de ces cas limites pour en d\u00e9duire une formalisation rigoureuse en termes de structures math\u00e9matiques \u00e0 l’aide de la th\u00e9orie des cat\u00e9gories. De cette formalisation sera d\u00e9duite une sp\u00e9cification en termes
\nde types qui sera ensuite port\u00e9e dans des langages de programmation. L’objectif sera de concevoir avant tout des m\u00e9canismes g\u00e9n\u00e9riques pour sp\u00e9cifier des syst\u00e8mes d’unit\u00e9s sur mesure plut\u00f4t que de se concentrer sur des grandeurs et des unit\u00e9s sp\u00e9cifiques particuli\u00e8res. Une impl\u00e9mentation haute performance en C++ sera produite en vue de contribuer significativement \u00e0 l’\u00e9volution du standard C++ pour y inclure une biblioth\u00e8que de grandeurs
\net d’unit\u00e9s et ainsi impacter directement des millions de d\u00e9veloppeurs, y compris les physiciens num\u00e9riciens sus-cit\u00e9s.<\/p>\n

Livrables<\/h3>\n

Concevoir une biblioth\u00e8que de grandeur des unit\u00e9s, visant \u00e0 contribuer \u00e0 l\u2019\u00e9volution du standard C++.<\/p>\n
