Bonjour, je poste dans installation faute de trouver mieux/plus approprié.
Ma machine est maintenant un peu vieille avec son AMD Athlon™ 64 X2 Dual Core Processor 4200+ × 2, ses 8Go de RAM et sa carte graphique GeForce GT 620/PCIe/SSE2 avec 2Go de RAM.
Aussi l'exploitation d'OpenCL me semble peut-être une bonne opportunité pour grappiller le peu de puissance que je peux encore trouver sur cette conf.
Sur ma machine fraîchement bootée, quand je lance DT, je vois dans l'onglet "fonctionnement" de la config que "activer le support d'Open CL" est grisé.
Dans un terminal, je lance un darktable-cltest qui me crache pas mal de chose, cf. plus bas.
Je relance DT et là, "activer le support d'OpenCL" n'est plus grisé ! Cool.
Pas facile de dire si la machine est plus rapide, faudrait un bench. Disons que si ça ne paraît pas nettement plus rapide, ça ne paraît pas moins rapide non lus !
Le pb, c'est que si je redémarre la machine, je constate que je reviens à la situation du début, et qu'il me faut refaire un darktable-cltest pour re-activer le support d'OpenCL.
Bon, je peux mettre ça en cron au boot, mais ça vous paraît normal à la base ?
Ci-dessous l'output du darktable-cltest, ce qui me chiffonne aussi un peu c'est la dernière ligne...
