Does not detect AMD GPU #17

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. Run Aparapi program on AMD Linux 64bit
2. Set device to GPU.

What is the expected output? What do you see instead?
Expected to execute on GPU, runs JTP.

verboseJNI gives:
platform name    0 Advanced Micro Devices, Inc.
platform version 0 OpenCL 1.1 AMD-APP-SDK-v2.5 (684.213)
platform Advanced Micro Devices, Inc. does not support requested device type 
skipping!

What version of the product are you using? On what operating system?
Aparapi 2011-10-13
Linux 3.0.0-12-generic #20-Ubuntu SMP Fri Oct 7 14:56:25 UTC 2011 x86_64 x86_64 
x86_64 GNU/Linux

Please provide any additional information below.
The machine has two Radeon cards, and lshw reports them as this:
*-display
    description: VGA compatible controller
    product: Antilles [AMD Radeon HD 6990]
    vendor: ATI Technologies Inc
    physical id: 0
    bus info: pci@0000:0c:00.0
    version: 00
    width: 64 bits
    clock: 33MHz
    capabilities: pm pciexpress msi vga_controller bus_master cap_list rom
    configuration: driver=fglrx_pci latency=0

Any special tricks I can use to figure out why it fails to recognize the cards?

That is weird.

Can you turn on enableVerboseJNI
(-Dcom.amd.aparapi.enableVerboseJNI=true) and scan the output.  This
should cause a roll-call of the available platforms and devices.

Also AMD APP SDK install includes a program called clinfo which will
list the available devices.  Can you confirm that this program is
seeing your device?

It almost looks like OpenCL is not installed.

Sorry I just reread this issue.  Clearly you had already tried verboseJNI.  

.. and OpenCL is installed or verboseJNI would not report the way it does. 

Can you email/post the result of running clinfo?

The JOCL binding works, so I am pretty sure OpenCL is installed.

Looks like OpenCL is not detecting your GPU device. It is detecting your 6 core 
CPU only (# of devices is 1)

I have the same CPU as you as well as a 5770 based GPU.  My clinfo output is 
shown below.

The default driver for your graphics card may not support OpenCL.

Start here http://support.amd.com/us/gpudownload/Pages/index.aspx but note that 
that you may have the option of installing OpenCL as an 'optional individual 
driver'. 

For example on this page 
http://sites.amd.com/us/game/downloads/Pages/radeon_win7-32.aspx the 
'individual driver' tab reveals an OpenCL driver. 

I can't explain JOCL working, unless JOCL is defaulting to use your GPU device 
(did you select GPU or ANY when you queried for suitable devices in your JOCL 
code?).

Here is my clinfo output.

The JOCL code I used had a small bug that caused it to select the CPU if there 
were no GPU present. After fixing that, it reports "No GPU" just like Aparapi. 

I will see if I can install new drivers. 

Feel free to close this issue, as it is likely a machine config issue, not a 
Aparapi specific issue.

I can add that the problem was that "X-Forwarding" was enabled for my SSH 
connection. Disabling XForwarding made CLInfo and Aparapi detect the cards.

Nice find.  I would never have thought of that. Glad you got it working. 

BTW how did you diagnose this?

I will close this issue.

I asked the machine maintainer if I could upgrade the driver, and he said it 
works fine but that XForwarding messes up OpenCL. I have no idea how he found 
out though :)
