Linux64-GPU crash

[alacant]

Hi Ivo, everyone
kubuntu 20.04
1.7.422

Launching the gpu version we get to the opening screen but then it disappears. The only evidence I can find is:

Oct 5 19:00:49 steve-desktop dbus-daemon[1111]: apparmor="DENIED" operation="dbus_method_call" bus="session" path="/modules/kwalletd5" interface="org.kde.KWallet" member="isEnabled" mask="send" name="org.kde.kwalletd5" pid=20589 label="snap.chromium.chromium"
Oct 5 19:00:49 steve-desktop dbus-daemon[1111]: apparmor="DENIED" operation="dbus_method_call" bus="session" path="/modules/kwalletd5" interface="org.kde.KWallet" member="close" mask="send" name="org.kde.kwalletd5" pid=20589 label="snap.chromium.chromium"

The non gpu version launches and runs fine.
Any way of getting any more debugging info?

Cheers,
Steve

Is it just this version and did previous GPU versions run fine?
Or is this the first time you are trying the GPU version?

Can you run the command 'clinfo' and paste the output here?

Hi Ivo,
The previous GPU versions didn't work either.

It appears you do not have any OpenCL compatible hardware (or drivers) installed.
What are the specs of your machine?

[alacant]

Ah, OK. Thi's this one. i5 with 8GB of ddr3:

Your machine should have an iGPU, which should definitely yield some marginal speedups.
I think there is a Linux initiative for Intel iGPUs called Beignet.
See if you can find that package in your package manager.
Once installed, this should (hopefully) give you OpenCL support for your iGPU.
Let me know if that works!

hi
OK. the package for kubuntu 20.04 is:
beignet-opencl-icd

Installed but:

./StarTools-Linux64-GPU
ASSERTION FAILED: Double precision not supported on this device (if this is a literal, use '1.0f' not '1.0')
at file /build/beignet-U5Obfe/beignet-1.3.2/backend/src/backend/gen_insn_selection.cpp, function void gbe::ConvertInstructionPattern::convertBetweenFloatDouble(gbe::Selection::Opaque&, const gbe::ir::ConvertInstruction&, bool&) const, line 6227
Trace/breakpoint trap (core dumped)

Any ideas?

Progress! I will shortly PM you with a download link for a preview of 1.7.423 which will hopefully work for you.

Sorry, no idea how to reply to the pm.

still no luck.

Hmmm... are you absolutely sure you are running that latest version, including updated 'resources' file?
The laptop i tested on has the exact same limitation (single precision floats only) and works a-ok now with Beignet...
