J'implémente pour le moment le nouveau module 'OpenCL qui permettra d'utiliser directement cette technologie dans les scripts Abstrasy.
Bien sûr, au moment où j'écris ces lignes, l'implémentation est réduite mais elle fonctionne.
Donc, bien que toujours à l'état embryonnaire, le module 'OpenCL est tout de même assez révélateur des avantages que peut procurer Abstrasy.
En réalité, pour utiliser l'OpenCL, l'interpréteur récupère et charge tout seul l'API JOCL qui est intégrée au paquetage principal Abstrasy. Il n'est donc pas nécessaire d'ajouter soi-même cette bibliothèque au classpath. L'interpréteur s'en occupe et “à chaud”.
Voyez ci-dessous un script d'exemple qui affiche à l'écran les informations du matériel OpenCL disponible. Comme vous pouvez sans doute le constater, le module 'OpenCL n'est pas un simple wrapper de l'API JOCL. Il propose une interface adatée pour le langage. Il profite ainsi de nombreux avantages et d'une grande simplicité.

A première vue, ce résulat peut étonner. Mais, il est correcte. L'interface OpenCL NVIDIA ne présente pas les CUDA cores, mais les SMX. Du coup, les informations ci-dessus sont plus évidentes. La carte NVIDIA QUADRO K5000 possède bien 8 SMX (et chacun contient 192 unités de calculs - les CUDA cores).
A titre indicatif, voici le résultat obtenu sur un iMac. Ici, le script énumère chaque équipement matériel (devices) GPU et CPU :
