What steps will reproduce the problem?

1. add line like #pragma OPENCL EXTENSION cl_khr_global_int32_base_atomics : enable
   or #DEFINE JUNK 1 to source of a kernel completely working kernel
   2.Call OpenCLLibrary.INSTANCE.clCreateProgramWithSource, the array version
   3.Call OpenCLLibrary.INSTANCE.clBuildProgram

What is the expected output? What do you see instead?
expected CL_SUCCESS got CL_BUILD_PROGRAM_FAILURE
and build log has "No kernels or only kernel prototypes found."

What version of the product are you using? On what operating system?
beta4, SN

Hi,

I know it is a known limitation that BridJ does not support passing struct by value. I just wanted to leave it here as an issue to be notified in case this feature is ever implemented. Feel free to close the issue if you don't plan on adding it.

Thanks for this great library.

A feature I was missing from JavaCL is the support for loading binary kernels. I suppose that the reason is that for most kernels it is a non-issue to compile from source on program startup, thus there was no need for this function. Well, I have a kernel that takes 99 minutes to compile, so I pretty much needed to implement this feature, and now I kindly ask for official inclusion.

Implementation is short and straightforward, but nonetheless, I attach the diff with which I hacked the functionality into OpenCL; it cannot hurt. (The "hacky" part is that, because I couldn't figure out how to use PointerByReference, I added an overload with a String[] parameter to OpenCLLibrary; magically an implementation is generated for it, this one I could use.)

Calling CLEvent.waitFor with more than one event parameter results in a
segmentation fault.

The bug is in the function CLEvent.to_cl_event_array; this function does
not correctly assemble the event array if there are multiple events. The
iDest value (declared on line 212 in revision 794) which is used to fill
the result array is never incremented and is thus always 0.

int iDest = 0;
for (int i = 0; i < n; i++) {
CLEvent event = events[i];
if (event == null || event.getEntity() == null)
continue;
event_wait_list[iDest] = event.getEntity();
// missing "iDest++;"
}

What steps will reproduce the problem?

1. call CLPlatform#toString() and print result

What is the expected output? What do you see instead?

i see:
Using platform [...] profile: FULL_PROFILE, extensions:
[Ljava.lang.String;@1a1c887}

instead of [Ljava.lang.String;@1a1c887 should be list of extensions

What version of the product are you using? On what operating system?
1.0-beta-2

Please provide any additional information below.
CLPlatform.java line 51:
return getName() + " {vendor: " + getVendor() + ", version: " +
getVersion() + ", profile: " + getProfile() + ", extensions: " +
getExtensions() +"}";

should be changed to:
return getName() + " {vendor: " + getVendor() + ", version: " +
getVersion() + ", profile: " + getProfile() + ", extensions: " +
Arrays.toString(getExtensions()) +"}";

The 0.9.6 binaries available at http://nativelibs4java.sourceforge.net/maven/com/ were compiled with Java SE 6 (as per META-INF/MANIFEST.MF):

Manifest-Version: 1.0
Build-Jdk: 1.6.0_22
Built-By: ochafik
Created-By: Apache Maven
Archiver-Version: Plexus Archiver
.
.
.

Is it really necessary to use Java SE 6? Wouldn't it compile under Java 5.0 or, perhaps, Java 1.4?

The pom.xml files doesn't state clearly which version is necessary.

To my reckon, such a low-level project won't need Java 6 (which has only some enterprise grade additions, like XML serialization, custom annotation processors). Java 5.0 is still necessary if using some constructions like annotations, foreach, generics, among others.

The implementation of Pointer#pointerToAddress(long, Class, Releaser) does not use the releaser argument. Instead it passes null to Pointer#newPointer.

If this is intentional it would be better to remove the Releaser argument.

Within my Java Program I create a CLImage2D from a BufferedImage "current_frame" the following way:

CLImage2D image = context.createImage2D(CLMem.Usage.Input,current_frame, false);

Although my BufferedImage is of the type TYPE_USHORT_GRAY (16bit grayscale), the CLImage2D is converted to an 8bit image.

I think this conversion is caused by the usage of the BufferedImage.getRGB function:
CLContext.createImage2D retrieves the pixel data of the BufferedImage via the function getImageIntPixels which is a member of the nativelibs4java. util.ImageUtils class. This function uses the BufferedImage.getRGB function in line 39

see:
http://code.google.com/p/nativelibs4java/source/browse/branches/OpenCL-BridJ/libraries/OpenCL/Core/src/main/java/com/nativelibs4java/util/ImageUtils.java?r=1195

The BufferedImage.getRGB function converts the data to 8bit.
see:
http://download.oracle.com/javase/1.4.2/docs/api/java/awt/image/BufferedImage.html#getRGB%28int,%20int%29

Maybe this problem can be solved by using the BufferedImage.getData function instead and then using the Raster.getPixels function to get the actual pixel data from the Raster.

Hi

It would seem line 199 in CLPlatform is incorrect,
it always creates a context on only 1 device:

cl_context context = CL.clCreateContext(null, 1, ids, null, null, errRef);

while it probably should read

cl_context context = CL.clCreateContext(null, nDevs, ids, null, null,
errRef);

or?

Including a few important ones, like CL_MEM_READ_ONLY. I'd like to use this,
but the missing parts are kind of a big deal.

I think the CLMem class has a bug on lines 71-72
#70: Input(CL_MEM_READ_ONLY, Flags.ReadOnly), /7correct
#71: Output(CL_MEM_READ_WRITE, Flags.WriteOnly), //incorrect
#72: InputOutput(CL_MEM_WRITE_ONLY, Flags.ReadWrite); //incorrect,

I think it probably should say

Input(CL_MEM_READ_ONLY, Flags.ReadOnly),
Output(CL_MEM_WRITE_ONLY, Flags.WriteOnly),
InputOutput(CL_MEM_READ_WRITE, Flags.ReadWrite);

Best Regards,
Johan

What steps will reproduce the problem?

1. Create a class with the following main method:
   //////////////////////////////////////////////////////////////////////
   public static void main(String[] args){
   try
   {
   CLContext context = JavaCL.createBestContext();
   CLProgram program = context.createProgram("__kernel void
   myKernel(__global const float* input, __global float* output, float
   multFactor) {" +
   " int i = get_global_id(0);" +
   " output[i] = input[i] * multFactor;" +
   "}").build();
   }catch(Exception ex)
   {
   ex.printStackTrace();
   }
   }
   //////////////////////////////////////////////////////////////////////
2. Execute it.

What is the expected output? What do you see instead?
Expected output is exit with code 0.
Execution it gives me exit code 139, which is triggered by segmentation
fault.

What version of the product are you using? On what operating system?
javacl-1.0-beta-4-shaded.jar
Ubuntu Desktop 9.10 x86_64.
Nvidia toolkit version is 3.0 Beta.
Nvidia driver version is 195.30 Beta.

There is no hs_err_pidXXX.log file generated anywhere...
GDB backtrace doesn't give any additional info...

The code beautifully works with ATI Stream SDK 2.0 on the CPU, but fails,
when the /usr/lib/libOpenCL.so.* are replaced with NVIDIA ones.
NVIDIA samples and demos work beautifully.

1.Create array which size is 4097 (type of array doesn't affect the bug,
for example int[] or float[])

2.Initialize it with 1

3.Make necessary JavaCL Initialization

   ReductionUtils.createReductor(context, ReductionUtils.Operation.Add,
   ReductionUtils.Type.Float, 1);
2. FloatBuffer result = reductor.reduce(queue, clBufferInput, 4097, 64);

What is the expected output? What do you see instead?

->I'm using "javacl-1.0-beta-4-shaded.jar" on Windows 7, Nvidia Quadro FX 580

I attached .java which was used for tests.
Changing MaxReductionSize doesn't affect results.
If input data size is 4096 or lower it works fine.

Hi,

When I try to build nativelibs4java from source, I notice that 2 tests (JOGLTest and the Particles demo) import classes from com.sun.opengl.util. However, with the JOGL project having migrated to http://jogamp.org/, this package has been renamed upstream to com.jogamp.opengl.util.

As a result, when I download the latest JOGL from http://jogamp.org/ and run the Particles demo, I get a ClassNotFoundException: com.sun.opengl.util.FPSAnimator.

I tried to modify your source to use com.jogamp.opengl.util instead. But when I rebuild, Maven complains with:
[ERROR] COMPILATION ERROR :
[ERROR] [...]OpenCL/OpenGLDemos/src/main/java/com/nativelibs4java/opencl/demos/particles/ParticlesDemo.java:[49,29] package com.jogamp.opengl.util does not exist

Now, I don't see the jogl jar in your repo, nor the com..opengl.util classes, so I suppose they ship from your Maven repository. My Maven-fu is bad, so I could not find how to fix this locally.

Could you update your Maven repository (and those 2 demos) to use the new com.jogamp.opengl.util?

What steps will reproduce the problem?

1. Create a java application which use OpenCL4Java.
2. Run the java application and allocate memory objects.
3. When finalizing the objects, JVM may cause Invalid memory access error
   and process may become a zombie process or die.

The application should finish without Invalid memory access error.

Please provide any additional information below.
Thank you very much for creating this library. I can have fun using this
library. But, I sometimes faced invalid memory access error. So, I just
report here. But, the exception occurs in C code. So, this problem may not
be the problem in OpenCL4Java. The error occurs in JVM finalize thread, so
it may relate multi-thread access to OpenCL library. But, I'm not sure the
reason of this issue.

When I ran the attached java class, InvalidMemoryAccessTestCase, I
faced error like 'Invalid memory access of location 0x12 rip=0x7fff86cf533c'.

I got stacks from gdb and Activity monitor.(I tested jdk 1.5 and 1.6. I
could reproduce the issue with both JVM.)

I ran the application like this:

gdb> file /usr/bin/java

When trying to build a program and making an error, CLProgram.build will throw an exception with the build info as the description. Unlike other runtime calls though the first line contains the error code. e.g.

com.nativelibs4java.opencl.CLBuildException: Compilation failure ! (code = -11)

The line producing it has it commented out:
throw new CLBuildException(this, "Compilation failure ! (code = " + err + ")"/errorString(err)/, errs);

Run the beta-2 OpenCL4JavaBenchmarkTest under Mac OS X 10.6. This was
tested on a MacBook Pro with the GeForce 9600M GT enabled.

After some futzing, I found that changing the local size (i.e. the work
group size) to be 16 or 32, instead of 1, made it run ~4 times faster than
Java. This line needs to be changed in the testOpenCL_aSinB function:

  kernel.enqueueNDRange(queue, new int[] {dataSize}, new int[] {32});

For this to work, you also need to make the data size be divisible by 32
(so 1<<20 works better than 1000000) but you can pad the data set if is not
naturally a multiple of 32.

Making this change in the benchmark test might make it less confusing for
first time users who see slow performance.

I've created a sqlite bridj mapping. Everything works correctly except 64-bit integer parameters/return values. These seem to be getting truncated to 32-bit values for some reason.

Steps to reproduce

1. Run the attached unit test

Expected output
The returned value should equal Long.MAX_VALUE

Actual output
-1 is returned which is the first 32-bits of Long.MAX_VALUE. The same behaviour occurs with any other long value >= 1L << 32.

What steps will reproduce the problem?

1. Run matrix multiplication algorithm (tried a few, all show the same symptom)
2. Read the result using FloatBuffer

What is the expected output? What do you see instead?

Multiplying 1024x1024 matrix filled with 1.0 should return 1024.0 for all
elements; I am reading off 4.6012E-41 from both CPU and GPU.

What version of the product are you using? On what operating system?

JavaCL/OpenCL4Java 1.0 Snapshot, dated 2nd of January 2010.
I am running these on Snow Leopard 10.6.2/ Core i7 and ATI
Radeon HD4850.

If the JVM crashes, please attach the hs_err_pidXXX.log crash report file
written by the JVM.

JVM does not crash.

1. Run (1 to 10).map {i => j: Int => i + j}.map(_(10))

What is the expected output? What do you see instead?
When ScalaCL HAS NOT been installed via sbaz, I see the following, correct result:
scala.collection.immutable.IndexedSeq[Int] = Vector(11, 12, 13, 14, 15, 16, 17, 18, 19, 20)

When ScalaCL HAS been installed via sbaz, I see the following, incorrect result:
scala.collection.immutable.IndexedSeq[Int] = Vector(21, 21, 21, 21, 21, 21, 21, 21, 21, 21)

What version of the product are you using? On what operating system?

What steps will reproduce the problem?

// (1) ok
FloatBuffer filter = FloatBuffer.wrap(filterData);
CLFloatBuffer clFilter = context.createFloatBuffer(CLMem.Usage.Input,
filter, true);

// (2) fails, due to problem in NIOUtils
ByteBuffer input = ByteBuffer.wrap(inputData);
CLByteBuffer clInput = context.createByteBuffer(CLMem.Usage.Input, input,
true);

What is the expected output? What do you see instead?

Should work, but the result is:

Exception in thread "main" java.lang.UnsupportedOperationException:
Unhandled buffer type : java.nio.HeapByteBuffer

Hello Olivier,

please add the files to the repository otherwise it is not possible to
compile your demo programs.

Regards
Thomas

PS: ParticleDemo does not work in Webstart for me as well (ATI 5770, Linux
32-Bit) perhaps I can track it if I have all the sources.

I tried to compile the ScalaCL files and run the test class but didn't succeed. See the attached hardware report for configuration details.

if (str == Pointer.NULL) {
break;
}
result.add(str.getCString());
}
return result;
}
Returns empty list.
Compared to the following code which gives correct result:
public List f2(String a1, String a2) {
final List result = Lists.newArrayList();
final Pointer<Pointer> pointers =
library.f(pointerToCString(a1), pointerToCString(a2));
for (int i = 0; ; i++) {
Pointer str = pointers.get(i);
if (str == Pointer.NULL) {
break;
}
result.add(str.getCString());
}
return result;
}

Thanks,
Oleg.

Running BinaryKernelTest using 'mvn test' occasionally causes a segfault. The attached log (pid14000) shows that the error occurs when createKernel is called on a binary program. (Sometimes I also get other errors, suggesting memory corruption.)

Revision 1424, Windows, ATI Stream v2.2. I could not reproduce the error on Linux and NVidia.

For testing purposes, I have created a standalone version of this test (maven is slow). When running this version, the binary createProgram variant fails every time with either InvalidBinary or segfault (see pid13980). But insert a System.out.println(device.getName()) and then it hardly fails. Definitely some memory wierdness somewhere.

I have experienced no issues with the BridJ version of JavaCL on the ATI system.

Closed On:

If memory object release operations are used, various errors surface later in the program.

[What steps will reproduce the problem?]
Run the attached program (Release.java) on an NVIDIA OpenCL platform.

The test program allocates, uses, and releases a memory buffer object in an infinite loop.

[What is the expected output? What do you see instead?]
The program is expected to not terminate, printing the iteration count until it is aborted. Instead, it fails in about a second with various errors. In my tests, 19 out of 20 executions it failed between 1100 and 1600 iterations (the remaining execution failed after 5085). Among these runs, I got an OutOfResources error during CLKernel.enqueueNDRange in 3 cases, an OutOfResources error during CLEvent.waitFor in 10 cases, and a segfault in 7 cases. I used this command line to run the tests:

LD_PRELOAD=/usr/lib/jvm/java-6-openjdk/jre/lib/amd64/libjsig.so /usr/bin/java -client -Xint -cp ~/Letöltések/javacl-1.0-beta-5-shaded.jar:. Release

These various errors indicate memory corruption.

[What version of the product are you using? On what operating system?]
I am using javacl-beta-1.5-shaded.jar, Linux, NVIDIA driver version 256.53. The device I use for OpenCL is a GeForce GTX 285.

[If the JVM crashes, please attach the hs_err_pidXXX.log crash report file
written by the JVM.]
hs_err_pid13356.log shows a crash during clReleaseMemObject, hs_err_pid13674.log during clEnqueueNDRangeKernel.

In a second test case (NoRelease.java), I prevent memory object release operations. I remove the release function call from the loop, and store all allocated memory objects in a list to prevent finalization from triggering a release. This program does not fail. (I let it run for over 2 minutes, 250000 iterations.)

This crashes at LambdaLift.scala:73 :
{{{
trait Bug {
for (i <- 0 to 10) {
val crash = i
}
}
}}}
While this does not crash :
{{{
class Bug {
for (i <- 0 to 10) {
val nocrash = i
}
}
}}}

Same crash with other kinds of optimizations (Array.map, for instance).

Hi,

ScalaCL is not in official maven repository nor it builds automatically...

steps to reproduce:

1. checkout from svn
2. go to libraries/OpenCL
3. type "mvn install"

It says "successful", but the scalacl-1.0-SNAPSHOT.jar file has no classes
in it.

It's enough to run mvn install from libraries/OpenCL/ScalaCL.

So from libraries/OpenCL it won't build, but from libraries/OpenCL/ScalaCL
it will.

As of now even the official maven repository doesn't contain correct build
of ScalaCL but the one without the classes.

What steps will reproduce the problem?

Compile the following with ScalaCLPlugin:

class Test {
val a = new ArrayInt
for (i <- a) yield (i, i)
}

What is the expected output? What do you see instead?

Expected output is successful compilation, but the following error (compiled from sbt) is shown instead:

This could be driver related.

At work I use .getMaxWorkItemSizes() perfectly on linux 64 on
both quadro and tesla cards. However at home I'm on windows7 64
GTX260 and it does not work.

getMaxWorkGroupSize() however and all other information calls I
can find work absolutely normal, and I can run kernels just fine :P.

The error I get is

In OpenCL spec, the length of size_t would be 8 bytes on 64bits system.

But the NativeLong would be 4 bytes on Windows x64 system.

So the NativeLong could not be used to represent the size_t.

The new dataTypes was needed for accessing native functions, like size_t
and size_tByReference in java code.

For example:

public class size_t extends IntegerType {

    /** Size of a size_t, in bytes. */
    public static final int SIZE = Pointer.SIZE;// = Native.LONG_SIZE;

    /** Create a zero-valued size_t. */
    public size_t() {
        this(0);
    }

    /** Create a size_t with the given value. */
    public size_t(long value) {
        super(SIZE, value);
    }
}

public class size_tByReference extends ByReference {

    public size_tByReference() {
        this(new size_t(0));
    }

    public size_tByReference(size_t value) {
        super(size_t.SIZE);
        setValue(value);
    }

    public void setValue(size_t value) {
        switch (size_t.SIZE) {
            case 8:
                getPointer().setLong(0, value.longValue());
                break;
            case 4:
                getPointer().setInt(0, value.intValue());
                break;
            default:
                throw new RuntimeException("Unexpected word length: " +

size_t.SIZE);
}
}

    public size_t getValue() {
        size_t v;
        switch (size_t.SIZE) {
            case 8:
                v = new size_t(getPointer().getInt(0));
                break;
            case 4:
                v = new size_t(getPointer().getLong(0));
                break;
            default:
                throw new RuntimeException("Unexpected word length: " +

size_t.SIZE);
}

        return v;
    }
}
