[Résolu] L'OpenCL (GPGPU) ça marche chez vous?

Petit sujet sur OPENCL et le GPGPU (CUDA et autres SDK proprio) en général, avez vous des retours sur le bon fonctionnement ou non?

Actuellement avec le pilote libre et mesa les programmes plantent quand ils demandent à l'utiliser sur la carte graphique. Le résultat est souvent des erreurs de segmentations, voir le non fonctionnement (certains benchmark)

Par contre en utilisant par le cpu avec pocl ça fonctionne avec un i7 4771. Par contre "beignet" qui vient de chez intel lui ne fonctionne pas chez moi.

Donc n'hésitez pas à parler de votre expérience, ça aidera sans doute à faire avancer les choses.

Si vous avez besoin d'aide pour au moins que ce soit détecté, n'hésitez pas non plus.

Edit :
- Donc je rajoute que CUDA fonctionne très bien.
- Il serait bien d'avoir des retours sur le pilote propriétaire et le SDK d'AMD.
- Voir aussi le SDK propriétaire de Intel.

- Pocl ne fonctionne pas parfaitement
- Beignet (pour les puces Intel) plante

Re : [Résolu] L'OpenCL (GPGPU) ça marche chez vous?

J'ai un GPU Nvidia, et cuda installé.
Comment cela se teste-t-il ?

Re : [Résolu] L'OpenCL (GPGPU) ça marche chez vous?

Tu peux le tester avec ces petits programmes :
https://code.google.com/p/ocltoys/
avec :

pyrit benchmark (dans les dépôts)
clpeak

Blender (pour cuda il me semble qu'il faut juste configurer le rendu sur le gpu Cuda dans les préférences)

phoronix benchmark en propose d'autres
ViennaCL
X264-CL

Il y a aussi darktable, mais je sais pas si il prend CUDA en charge.

Pour les soucis avec les radeon et mesa, il semble que ce soit LLVM 3.5 qui provoque ces soucis. A voir...

Bon test avec la hd4600 intel et  "beignet" (pour utiliser la puce intégré), résultat ça plante toujours.

Cela semble liée à LLVM :'(.

Re : [Résolu] L'OpenCL (GPGPU) ça marche chez vous?

j'utilise CUDA depuis quelque temps, avec un geforce 780 GTX ( 2304 coeurs cuda)
en calcul pur avec NAMD ( dynamique moléculaire), fonctionne à merveille de même avec GROMACS.
pour ce qui est de la visualisation, le seul logiciels que j'utilise et qui le propose est VMD, la aussi ça fonctionne bien.

j'utilise pour ma carte nvidia le pilote via akmod-nvidia, la dernière version disponible.
avec en plus le dépot pour F20 de cuda, disponible via le site nvidia.

Re : [Résolu] L'OpenCL (GPGPU) ça marche chez vous?

Ok je note.

Ce serait bien d'avoir un retour sur le SDK proprio d'AMD.

Comme je test les développements du libre, je n'ai pas de quoi exploiter une version proprio. Surtout que j'utilise la version de dev de fedora.

Bon j'ai rapporté les défauts sur le bugzilla, défauts pris en compte d'après les infos que j'ai.

Si je récupère le dernier disque dur qui manque à mon système pour pouvoir avoir une version stable, j'en profiterai pour ajouter les tests des pilotes proprio à la liste.

AMD vient d'apporter des patchs pour le support de l'OpenCL dans Blender et son moteur Cycle :
http://www.blendernation.com/2015/03/24 … or-opencl/
https://docs.google.com/document/d/1LuX … iWbUY/edit

J'ai hâte de tester cela smile.

Les améliorations de l'OpenCL pour Blender par AMD devrait arriver avec la version 2.75.

Vivement que ce soit disponible que l'on test cela tongue.

Salut VINDICATORs, je vais avoir besoin de ton aide.

Je teste OpenCL dans le but de faire du calcul haute performance avec python. Première question : faut-il installer les paquets devel ou les paquets sans devel suffisent ? Deuxième question : pourquoi clpeak ne marche pas hmm ?

J'ai deux machines concernées :

Première machine sous Fedora 24

Quelqu'un a une idée pour utiliser opencl avec les 3 plateformes ?
Merci

Re : [Résolu] L'OpenCL (GPGPU) ça marche chez vous?

Pfiou cela remonte.

Sinon le support de l'OpenCL par le pilote libre avance petit à petit, mais ce n'est pas encore totalement fonctionnel.

J'en reparle dans la semaine n'ayant pas trop le temps maintenant.

Clair, c'est un beau déterrage de 2 ans, mais je n'ai pas trouvé de topic plus récent qui en parle, et il me semble que c'est un sujet qui est en plein essor.
Merci à toi. J'attends impatiemment ton retour, vu que j'ai un stagiaire qui démarre dessus. Entre temps je vais probablement passer à intel sdk.
Bonne soirée

 ~]# clpeak -p 0

Platform: Clover
  Device: AMD HAWAII (DRM 2.49.0 / 4.11.5-300.fc26.x86_64, LLVM 4.0.0)
    Driver version  : 17.2.0-devel (Linux x64)
    Compute units   : 44
    Clock frequency : 1040 MHz

Tiens chez moi clpeak se met à ne pas planter, mais n'affiche rien de plus...
Je relance la puce intel pour voir si cela à évolué.

Sinon voici le  lien pour savoir où ils en sont avec le support de l'OpenCL avec les pilotes libre : https://dri.freedesktop.org/wiki/GalliumCompute/

Blender 2.80-build https://builder.blender.org/download/ dispose d'un bon support, mais pas encore avec le pilote libre pour les radeon. A voir si c'est le cas avec l'intel.

Oui, clpeak bug avec les gpu amd, le bug est référencé https://bugs.freedesktop.org/show_bug.cgi?id=96897

Quel est l'intérêt d'utiliser blender, à part pour tester opencl pour du rendu ? Apporte-t-il un moteur de calcul différent de pocl, beignet et mesa-libOpenCL, ou bien s'appuie-t-il sur eux ?

Re : [Résolu] L'OpenCL (GPGPU) ça marche chez vous?

Il s'appuie sur l'opencl pour calculer les rendu.

L'intérêt c'est que... c'est pour faire de la 3D, montage vidéo/audio, 2D, animation, etc... Rien à voir avec clpeak ou autre.

Faut avouer quand même que cela pète plus que de voir des chiffres tongue!

C'est sûr que c'est plus joli, mais c'est quand même moins parlant que des chiffres dans un environnement de calcul scientifique. wink

Re : [Résolu] L'OpenCL (GPGPU) ça marche chez vous?

Bah tu les as aussi en chiffre vu que tu mets normalement beaucoup moins de temps pour faire les rendus wink.

Reste les tests disponible avec la suite de bench de phoronix-test-suite.

Mais bon ce n'est pas encore prêt vu qu’actuellement il semble que ce soit Vulkan qui est privilégié :'(.

Merci pour ces infos et vidéos.
N'ayant pas réussi à faire fonctionner correctement les logiciels opensource, je me tourne vers centos 7 qui me permet d'installer directement le sdk et le diver intel, et le driver amdgpu-pro. hmm

Dommage que personne ni ici ni sur phoronix n'ait pu m'aider à résoudre mon problème sad

Le souci d'aller toujours de l'avant.

Celui aussi de passer à autre chose alors que ce qui devrait être n'est pas totalement fonctionnel...

Après en entreprise mieux vaut utiliser CentOS/RHEL!

Tu parles de moi ou des programmeurs de l'opencl ? neutral

De toi pour CentOS/RHEL, si ta un stagiaire à mon avis c'est pas perso ou alors j'ai pas deviné la bonne solution.

Sinon c'était pour les dev sous linux...

Effectivement, c'est dans le cadre du boulot. J'avais espoir qu'avec Fedora j'aurai des paquets plus récents que sous centos et que ça fonctionnerait mieux, mais comme je n'ai pas réussi à faire fonctionner l'opencl correctement, je change de fusil d'épaule.

Celui aussi de passer à autre chose alors que ce qui devrait être n'est pas totalement fonctionnel...

Oui, c'est malheureux, mais le manque de bonnes volontés est présent dans tout le volontariat.

Re : [Résolu] L'OpenCL (GPGPU) ça marche chez vous?

Niveau professionnel il vaut quand même mieux privilégier la stabilité avec un support long (même si mettre plus de 10 ans avant de changer d'infra système c'est une belle bêtise pour rester correct...). De plus rien que le pilote "semi-libre/semi-propriétaire" AMD fonctionne pas mal sur RHEL/CentOS 7 et apporte l'OpenCL.

Il y a bon espoir d'avoir un support correct d'ici quelques temps, AMD apporte beaucoup de solutions qu'il faut intégrer maintenant.
