OpenCL vs denoiseprofile

[temperdu]

Bonjour,

Convaincu par DT sous Windows, j'ai migré sous Linux (Mint 18.3). Sur les conseils de membres, j'ai même acheté une carte graphique Nvidia au passage, juste pour DT. Mais je ne le trouvais pas aussi rapide que sous Windows.  Ma CG est une GeForce GTX 1060 3GB et OpenCL a l'air installé.

En lançant DT dans un terminal am moyen de darktable -d opencl, j'obtiens en effet les erreurs suivantes à chaque fois que j'exporte une photo

Code :

[pixelpipe_process] [export] using device 0

Il n'y a que denoiseprofile qui a l'air concerné. Comme indiqué ici https://www.darktable.org/2012/03/darktable-and-opencl/, j'ai augmenté opencl_memory_headroom pour le porter à 512. Pour info, avant d'arriver à cette erreur, au lancement, j'ai :

Est-ce qu'il y a quelques chose à faire pour avoir un DT tout rapide ?

EDIT

---

Je suis débile ! En augmentant opencl_memory_headroom dans darktablerc jusque 1024, j'arrive finalement à

Code :

[pixelpipe_process] [export] using device 0
[default_process_tiling_cl_ptp] use tiling on module 'denoiseprofile' for image with full size 5342 x 3688
[default_process_tiling_cl_ptp] (2 x 1) tiles with max dimensions 4204 x 3688 and overlap 32
[default_process_tiling_cl_ptp] tile (0, 0) with 4204 x 3688 at origin [0, 0]
[default_process_tiling_cl_ptp] tile (1, 0) with 1202 x 3688 at origin [4140, 0]

L'augmentation est peut-être rendue nécessaire par le fait que j'utilse un écran 4K.

Pour poser une question quant même : quels paramètres me conseilleriez vous dans "fonctionnement" pour ces histoires de tuiles, ainsi que les autres paramètres impliquant la mémoire ?

• Ma CG a 3GB de mémoire
  
• En RAM, le PC a 16GB

Merci @temperdu, ton sujet m'a permis de vérifier et corriger des valeurs d'opencl_memory_* dans mon darktablerc.

Je n'ai pas d'écran 4K et j'ai également du monter à 800 pour headroom pour ne pas "retomber" sur le CPU. (nVidia GK107GLM [Quadro K1000M] avec 2Go RAM). J'ai cependant deux écrans connectés.

Je n'ai pas trouvé d'informations sur les paramètres opencl_ qu'on a dans darktablerc. J'aurais pourtant bien aimé avoir des explications au delà de headroom dont le lien que tu cites précise :

This value tells darktable how many megabytes (out of the totally available amount) should be left free for driver and video purposes.

Car j'ai mis 800 "à tâtons" sur un export jpg répété avec des valeurs différentes et en contrôlant la sortie du -d opencl, mais comment savoir si cette valeur est correcte pour d'autres traitements, à part contrôler au coup par coup la console ?

@temperdu, veux tu mettre dans des boites "code" plustôt que "citation".

« Est-ce qu'il y a quelques chose à faire pour avoir un DT tout rapide ? »

Il faut ajuster les paramètres à tâtons en mesurant les temps d'exportation sur une image de référence. Il n'y a aucune règle absolue, ça dépend de la carte graphique et de la version de son pilote. Je me souviens que le driver Nvidia 375 donne les meilleurs résultats chez moi, avec des paramètres différents de ceux qui marchaient le mieux avec Nvidia 340.

Bon courage…

Bons tâtonnements comme le recommande Aurélien Pierre !

Vos échanges ainsi qu'une discussion sur la liste darktable-users m'ont poussé à aller vérifier ma configuration.

J'ai pour cela utilisé les outils cités dans les mail de la liste. À savoir, un raw de test avec son fichier xmp qu'on peut télécharger
$ wget http://www.mirada.ch/bench.SRW
$ wget http://www.mirada.ch/bench.SRW.xmp

Ainsi que les lignes de commandes pour l'utiliser
$ darktable-cli bench.SRW test.jpg --core --disable-opencl -d perf
$ darktable-cli bench.SRW test.jpg --core -d perf -d opencl

En lançant la première ligne (sans opencl), le traitement s'effectue en environ 37 secondes

J'ai ensuite fait un essai avec opencl, mais en regardant le log du traitement, je me suis aperçu qu'un module n'était pas traité avec opencl, il s'agit du module atrous (l'égaliseur en français). Le message d'erreur était le suivant :

Code :

default_process_tiling_cl_ptp] use tiling on module 'atrous' for image with full size 5490 x 3660
[default_process_tiling_cl_ptp] (2 x 1) tiles with max dimensions 4400 x 3660 and overlap 256
[default_process_tiling_cl_ptp] tile (0, 0) with 4400 x 3660 at origin [0, 0]
[opencl_atrous] couldn't enqueue kernel! -4
[default_process_tiling_opencl_ptp] couldn't run process_cl() for module 'atrous' in tiling mode: 0
[opencl_pixelpipe] could not run module 'atrous' on gpu. falling back to cpu path

Le temps de traitement dans ce cas était d'environ 15 secondes
J'ai alors tâtonné avec toutes les variables opencl_xxxx pour finir par trouver que je devais augmenter la valeur de opencl_memory_headroom. Sa valeur est par défaut de 300. Et contrairement à ce qu'on pourrait penser en lisant la description de cette variable, il ne faut pas réduire sa valeur, mais l'augmenter pour faire en sorte que tous les modules soient traités avec opencl. Cependant il ne faut pas trop l'augmenter. sinon tout est bien traité en opencl, mais les performances diminuent. En clair quand je l'augmente juste ce qu'il faut pour que tous les modules soient traités avec opencl, soit chez moi, 500, j'obtiens un temps de traitement d'environ 8,5 secondes. alors que lorsque j'augmente fortement la valeur, par exemple à 2000 le temps approche les 10 secondes. Si on examine le log, on s’aperçoit qu'à cette valeurs de nombreux modules se mettent à découper leur traitement en blocs successifs (des tuiles dans le jargon darktable), ce qui n'est pas le cas à 500. Ma carte graphique ne dispose que de trois gigaoctets de mémoire. ce qui doit expliquer le phénomène

Conclusion, il faut augmenter la valeur de opencl_memory_headroom juste assez pour que tous les modules soient traité en opencl, mais pas plus. Chez moi, c'est 500

[pascal]

Je ne suis pas certain que cela soit le meilleur test. En fait ce qui me semble le plus important c'est l'interactivité. Avec OpenCL et le module liquéfier par exemple en interactif il y a une grosse différence lorsque l'on navigue dans l'image. D'une manière générale j'ai plusieurs fois détecté que l'OpenCL n'était pas activé sur ma machine pendant l'utilisation de darktable. Et pourtant lorsque je fais le test d'export (qui traite TOUTE l'image) comme toi ci-dessus j'ai des perfs équivalentes ou moins bonnes avec OpenCL. Mais finalement je pense que la vitesse de l'exportation est bien moins importante que la fluidité des traitements. J'exporte à la fin et je peux aller prendre un café pendant que la machine tourne

Sinon comme toi, en passant à 500 les performances sont meilleures car plus de modules passent en GPU.

[aurelienpierre]

la vitesse d'exportation compte autant que l'interactivité quand tu te retrouves à exporter 200 photos d'un mariage en 36 Mpix (à haut ISO, donc débruitage à fond).

ça m'avait pris plusieurs heures...

Merci !

Bon y'a pas tous les paramètres, et c'est pas super-probants sur les tests que j'ai pu réaliser jusqu'alors.
Il faut un carte puissante et dotée de RAM pour sentir vraiment les effets d'openCL.
