Linux64-GPU crash

[admin]

That said... I'm running Beignet 1.4, while you seem to be running an older version...

I'm running it from the same folder so same resources...

Hi
From where did you get beignet v1.4?

[admin]

Very, very strange. The error doesn't seem to be congruent with the OpenCL code it is (should be) compiling. Given it runs on 1.4 (and I have not had any reports of any other issues), I'm inclined to say the problem is the old version of Beignet.

Hi
From where did you get Beignet v1.4?

I built it from scratch per the instructions.

There is also the NEO project

https://github.com/intel/compute-runtime/releases.

FYI, finally figured this out for my machine and Kubuntu 18.04.
The 1.7.440 GPU version now starts!

Needed to add these packages:

Beignet
ocl-icd-dev
ocl-icd-libopencl1

- Bob

[alacant]

add these packages

@devonshire Thanks for posting.

Unfortunately, Beignet on Ubuntu is dead upstream as it is to be replaced by the intel opencl version. This means that unless you have recent GPUs, it's never going to work. e.g. my GPU is Haswell on an i5-4210Y, so unless I write my own opencl, it's never going to work. A pity because I know Ivo has put a big effort into speeding up compute.
cheers

Ah, well...

No matter, for me. It ran for a while, then started to draw masks halfway down the screen before stalling out.
Figured I was looking at a graphics memory limitation and gave up on it, as I won't be allocating more.
Perhaps on the next machine! In the meantime, the non-GPU version seems fairly stable.

I observed that same issue on my i5 5300U laptop, but solved it by switching acceleration from SNA to UXA (see this thread).

It's quite frustrating how many years on since I first looked into GPU acceleration (and determined it was not mature enough), the state of it is still buggy and unreliable depending on the hardware, drivers and OS.

I have the same issue, but on openSUSE Tumbleweed x64 (GNOME).
My hardware is:
- nVidia Quadro P600
- Intel(R) Xeon(R) W-2123
- 32GB ram DDR4

When I start the GPU version, it crashes immediately. From terminal there is no output whatsoever.
I've installed the openCL packages, included the ones listed above

I'm using v1.7.451 RC1

EDIT: I have installed beignet, and now I get the following output:

[admin]

Thank you for the very useful output. It appears there is no OpenCL compatible device detected at all on your system.

You can use

Code: Select all

clinfo

to confirm.
