I would like to use my Intel GPU, too but haven't got any work for it so far. Does anyone know if it is supported under Linux? Einstein said it couldn't give me any work as Intel GPUs under Linux aren't supported with them.

Intel GPUs work under Linux, just need drivers such as Beignet for some GPUs.
----------------------------------------To allow multiple work units to run need entries in app_config. PCs that also have AMD or Nvidia cards need "use_all_gpus" in cc_config and entries in app_config for each GPU type. Search this and other GPU threads for details. Paul.

Thanks Paul. This computer is equipped with an Intel UHD 630. I started reading stuff about Beignet drivers but to me it seems you need to be a programer to get it to work so I will refrain from it so as not to screw up the whole system.

Back to the CPU requirement for Intel GPU-tasks... Could this be because these tasks are different from the ones for AMD/NVIDIA GPUs? Already for a while I noticed that upon running those, the CPU is busy for a few minutes.
For instance, have a look at the result log for task 1664412021: INFO:[04:08:24] Start AutoGrid... That's ~9 minutes CPU time, although there are tasks in which this goes a bit faster: 1683883440 (6min), 1678557372 (4.5min), 1677950983 (4min), 1663430386 (3.5min). Instead, for AMD or NVIDIA GPU-tasks, AutoGrid is muuuuch faster (and hence less CPU involved): 1686421472 (16s), 1686421259 (15s), 1686418876 (13s), 1686417831 (10s), 1686418543 (9s). How could this be? The only difference I noticed in the result logs is that the job names for Intel GPUs are OB3ZINC***, whereas for AMD/NVIDIA it's ZINC***. So Intel GPUs may indeed be fed with different tasks, which may indicate that the CPU requirement is not a bug, but a 'feature'. (I guess in some days you won't be able to access these result logs anymore, so be quick) ;-) |

H, good catch, goben! Well, this disproves my theory. I never encountered those, but I admit that I didn't search thoroughly.
Ah, and thanks for making the devs aware of the bug in the dedicated thread. Let's see... Currently it seems that also Intel GPU-tasks ran out... I didn't receive any anymore. |

I just searched for intel gpu in Ubuntu software list, found Beignet, read the description and selected it for install.
----------------------------------------Re-start to activate and it worked. Paul.

Hi Paul. Oh that was easy! Didin't know the driver was available under software. What I read online was way more complicated with additional libraries from third parties. I got it installed but neither project which supports Intel GPU sends me work. WCG probably doesn't have any at the moment, Collatz claims that there is work for Intel, I just didn't select it and Einstein doesn't tell me anything. Presumably something is still missing or incompatible. Oh well. It isn't that important. But thanks for your help.
