OpenCL

[Momoko_Fan]

I found some new bugs
This is on a different machine, btw. With ATI Radeon HD 5770.

Exception in thread "main" java.lang.NullPointerException

        ... 1 more

Do note that it has OpenCL, I have GPU Caps Viewer installed and all the OpenCL demos work fine there.

Also, for 64 bit LWJGL only:

Exception in thread "main" java.lang.LinkageError: Version mismatch: jar version

        at org.lwjgl.Sys.<clinit>(Sys.java:105)

        at org.lwjgl.test.opencl.HelloOpenCL.main(HelloOpenCL.java:182)

Looks like someone needs to update lwjgl64.dll?

[spasi]

About the first problem: Could you run the same tests with lwjgl-debug.jar and -Dorg.lwjg.util.Debug=true and see what the output is? Also, what version of the Stream SDK is installed on that machine?

[Momoko_Fan]

Okay here it is with HelloOpenCL.
ATI Stream version 2.2, Catalyst 10.9.

The fractal demo works fine on the GeForce, but there's no change in the fps with the new LWJGL build.

[spasi]

Hmm. First of all I'm pretty sure you don't have the latest build. Try these:

lwjgl.jar
lwjgl-debug.jar
lwjgl_test.jar
lwjgl.dll

About the CL_PLATFORM_NOT_FOUND_KHR error, I think you're having problems with the ICD. Try to reinstall Stream, I think I read somewhere of people having the same issue. Also make sure [HKEY_LOCAL_MACHINE\SOFTWARE\Khronos\OpenCL\Vendors] in the registry has proper values.

[Momoko_Fan]

Okay I updated to the latest version.
I went to
HKEY_LOCAL_MACHINE\SOFTWARE\Khronos\OpenCL\Vendors

and it has two keys:
atiocl.dll
atiocl64.dll

Both of them set to DWORD:0
Setting them to DWORD:1 doesn't do anything.

I uninstalled ATI Stream Developer SDK and re-installed it.
Still getting the same error as before.
And by the way, JOCL Hardware Report works fine.



With the new version on the GeForce I get the same output as before but now instead of the exception I get this line

        CL_DEVICE_EXTENSIONS = cl_khr_byte_addressable_store cl_khr_icd cl_khr_gl_sharing cl_nv_d3d9_sharing cl_nv_d3d10
_sharing cl_khr_d3d10_sharing cl_nv_d3d11_sharing cl_nv_compiler_options cl_nv_device_attribute_query cl_nv_pragma_unrol
l  cl_khr_global_int32_base_atomics cl_khr_global_int32_extended_atomics

So I think that one's fixed. 

But now, DemoFractal doesn't work

AMD error

Hmm. Obviously LWJGL loads OpenCL.dll and is able to detect OpenCL 1.0 (at least) and run clGetPlatformIDs. There's nothing else that runs in between. Can you try a simple test please? Compile and run the following code:

public static void main(String args[]) {
       try {
            CL.create();
        } catch (LWJGLException e) {
            e.printStackTrace();
        }
        IntBuffer num = BufferUtils.createIntBuffer(1);
        int errcode = clGetPlatformIDs(null, num);
        System.out.println("Platform count = " + num.get(0));

        PointerBuffer platforms = BufferUtils.createPointerBuffer(num.get(0));
        errcode = clGetPlatformIDs(platforms, null);
        System.out.println("Platform[0] = " + platforms.get(0));
}

NV error

Are you sure you downloaded and replaced all 4 files I linked above? How exactly do you run the test?

[Momoko_Fan]

NV error

Are you sure you downloaded and replaced all 4 files I linked above? How exactly do you run the test?

Yes I am sure.

Here's the commandline I am using:

java -cp lwjgl-debug.jar;lwjgl_test.jar org.lwjgl.test.opencl.gl.DemoFractal

Surprisingly enough, if I change the lwjgl-debug.jar to lwjgl.jar, it goes past that error, but I get a black screen, and a OpenCL compiler error:

OpenCL COMPILER OPTIONS:  -D USE_TEXTURE
BUILD LOG: :66: error: use of undeclared identifier 'float3'
            float3 oc = (float3)(
            ^
:71: error: use of undeclared identifier 'oc'
            write_imagef(output, (int2)(ix, iy), (float4)(oc / 255.0, 1.0));

[spasi]

OK, I've updated the files above, lwjgl-debug.jar was indeed old, sorry about that. Download the 3 jars again and you should also need lwjgl_util.jar in your classpath for the fractal demo. The compiler error should be fixed as well, apparently OpenCL 1.0 didn't have support for 3-component vectors, weird.

Its attack of the evil errors! There's no escape!
Yeah, you fix a small error, then a bigger one pops up. Big animal eating smaller animal, etc..
The error happens when compiling the program:

org.lwjgl.opencl.CL10.nclBuildProgram(JILjava/nio/ByteBuffer;ILjava/nio/ByteBuffer;IJJJ)I

It seems like a common error that happens with OpenCL program doing incorrect things.
Also, passing the "-forcePBO" argument fixes the issue, so its gotta be in the way textures are handled.

[spasi]

I switched to my old 8800GTX and managed to fix this. I also applied for NV’s GPU Computing developer program, I'll try to do some tests with their 1.1 implementation when I gain access. Lets hope they release it soon enough, getting crashes because of compilation errors is not good. Btw, my 8800GTX was running the fractal demo at ~230 fps.

I've updated the jars above if you'd like to verify this.

About the clGetPlatformIDs problem on Stream, were you able to run that test code I posted above?

[Momoko_Fan]

I wasn't able to test it on ATI yet, sorry.
With the latest jars, it seems to work on the GeForce.
Don't worry about the low framerate, the GeForce 8400M GS is an entry level card that has very low performance.
Here's a comparison: http://www.gpureview.com/show_cards.php?card1=474&card2=531
The 8400 has 25.6 GFLOPS, while 8800 has 345.6 GFLOPS.
Thats a ratio of 13:1, so the 17 fps I am getting * 13 = 230, which is the fps you're getting

[Momoko_Fan]

Okay I ran it on the ATI

Platform count = 1
Platform[0] = 87741452

EDIT: Hey what do you know .. The HelloOpenCL test works now!

Nice! What about the fractal demo?

[Momoko_Fan]

Fractal works as well .. about 150 fps.

[spasi]

Cool, I was also able to test on a macbook last night, it works there too except native kernels (probably useless in Java) and GL sharing (we need to re-implement our Mac context implementation?).

So, famous last words I know, but:

Matzon, I think I'm done now, feel free to release 2.6 whenever you can.
