Bonjour,
J’installe, je lis, je relis et je comprends rien.
Juste une question : est-il possible d'avoir OpenCL avec DT 2.4 sur Ubuntu 16.04 avec une carte Intel® HD Graphics Skylake ULT GT1.
J'ai installé Beignet. et j'ai suivi la procédure donnée ici : https://askubuntu.com/questions/850281/opencl-on-ubuntu-16-04-intel-sandy-bridge-cpu
Mais dans DT, j'ai toujours OpenCL "not avaliable".
En tripatouillant ces trucs Je suis bien au-dela de ce que je sais faire sur Ubuntu. Un avis éclairé me ferais du bien. Merci
Voici mon clinfo puis le resultat du tools-master.
