Initial  example-shade project attempt.  Which can hopefully allow shader toy like playground using HAT.

At this point the code is just a copy of heal. With some uniform data structures in place. 

More to come.

Commit messages:
 - Initial uniform data vec3,vec2,vec4,ivec2 and float buffered image experiments
 - Initial shade implementation (cloned heal)

Subject: Draft incubator code reflection JEP
Message-ID: <629DB9A6-C1A3-42D4-A0A7-EEE0C9602359@oracle.com>

Hi,

A draft incubator code reflection JEP is now visible here https://openjdk.org/jeps/8361105

I would like to emphasize its *draft* and *incubator* status. There are likely to be significant edits to this draft JEP before it is submitted and it works its way through the JEP process. I don?t expect there to be major changes to the design of the incubating API and implementation. We think it's good enough for experimentation as an incubating API, based on our own experiences building various experiments. I do expect changes as it re-incubates and we learn more from experiments. The best way to provide feedback in that regard is to play with it, and resist, for example, the temptation to comment deeply on the current means of declaring reflectable code.

The JEP aims to provide a more solid foundation for HAT, the other significant peer of Project Babylon?s efforts. As HAT builds its programming model for parallel programs that translate to code that executes on GPUs we will learn more about how it uses code reflection to better improve both as we re-incubate.

Paul.

Shade needs fvec2,3,4  and ivec2 types. So experimenting with adding them to Uniform list .

Also discovered that Panama/memorySegments are actually pretty efficient when holding RasterData types (for copying to ImageBuffers)

To prove the case I added an 'OpenGL free' nbody variant (curently in the shade-experiment code)

Extracted the nbody implementation from the example-shade dir and created a non opengl example.

Moved nbody to nbodygl and turned nbody into an opengl free implementation.


java @.bld
java @.run ffi-opencl nbodygl  # prev opengl version
java @.run ffi-opencl nbody     # new non opengl version

> Use the result of the buffer tagger for labeling buffer accesses. The manual annotations and the results of the buffer tagger are still compared with an assertion.
> 
> Also fix manual annotations and prevent buffer tracking from being injected for an accelerator.

Tighten terms, esp. around the state transitions of operations and other items that change from unbuilt to built when an associating block transitions from unbuilt (and inaccessible) to built (and accessible).

Add checks when constructing an operation or block reference to ensure only unbuilt values are used, so failing on construction rather than when an operation is appended to a block builder. (Later we can do much better on error messages and even printing out unbuilt models to aid debugging.)

When moving code from shade example to experiments.  I noticed that we were generating multiple typedefs for the same iface type if a buffer contained multiple fields. 

So this PR has the code refactoring and a fix for de-duping the typedefs.

Hi Paul,
 >A draft incubator code reflection JEP is now visible here
https://openjdk.org/jeps/8361105
I would like to point out a couple of things that are not super clear to me
on a first read.
>As the GPU library traverses the code model it will encounter an element
>that models the invocation expression to the gray method. .....
> To achieve this we must declare that the gray method is also reflectable
Does it mean we should only call those methods which can be annotated
with @Reflect.  Therefore, effectively we should not invoke 3rd party/ even
JDK library methods?
>Foreign programming models
Font size of it is too small to notice it as a section header while reading
from a mobile phone.
>In total there are four syntactic locations where @Reflect can appear that
governs,
But I could only see 3 bullet points instead of 4. Are two of them fused
in one?
Would it be possible to show an example of each of them and refer from it
here so that it will be a bit more clear.
I can see you mention `cast expression`, could you please clarify what that
also really means?

Best regards,
Nadeesh

Ok the raw shade toy ui is up and running.  

Also added `.toy` so we can run using scriptable java 


java @.bld 
java @.toy blue.java


Where blue.java is 

import hat.Accelerator;
import hat.backend.Backend;

    var shader = new Shader() {
        @Override

I had incorrectly assumed that fragCoord was 0f->1f (OpenGL style) it is/was not.  It is bound by iResolution

Implemented iResolution and iMouse. 

Need more complicated shaders multithreaded Java easily maintains sub 2ms shader compute.

I would like to point out a couple of things that are not super clear to me on a first read.

Does it mean we should only call those methods which can be annotated with @Reflect.  Therefore, effectively we should not invoke 3rd party/ even JDK library methods?

It depends on the use case, and in the GPU case where the parallel program is executed. When executing on a GPU it would make no sense to look into the Math.sin method and translate it (even if there were permission to do so, since it was not written for use in such parallel programs) and instead treat it as an intrinsic. However, when executing on the JVM we can directly invoke the gray method or Math.sin as Java ordinarily does since they both supply executable implementations as bytecode that executes on the JVM. (Executing on the GPU does not guarantee preservation of Java program meaning e.g., the accuracy of the sin implementation might differ, and in general the order in which floating point operations occur might also differ.)


>Foreign programming models
Font size of it is too small to notice it as a section header while reading from a mobile phone.

That?s hard to address directly, but I expect this section, or parts of, will be made more prominent as it hides an important point about preserving (or not) semantics of Java code.


>In total there are four syntactic locations where @Reflect can appear that governs,
But I could only see 3 bullet points instead of 4. Are two of them fused in one?

Yes, in bullet two because it would just duplication the text for fields and local variables.


Would it be possible to show an example of each of them and refer from it here so that it will be a bit more clear.

Yes, we can.


I can see you mention `cast expression`, could you please clarify what that also really means?


Object o = ?";
String s = (String) o;

We cast o to s using the cast expression "(String)?.

Hi,

Thank you for the clarification.

Any performance implication whenever a @Reflect  annotated  method executes
on the JVM?

If an instance method is  @Reflect  annotated, I hope  that it does not
carry over to its overridden method in child class. Should that need to be
explicitly documented in the JEP or is that implicit?`

> declaring a reflectable lambda expression does broaden the scope to the
surrounding code of final, or effectively final, variables used
Could you please expand on how the scope broadens for the  final, or
effectively final, variables in the lambda?
Should not the same happen for instance fields that are used in @Reflect
 annotated  method ?`

Best regards,
Nadeesh

No (or at least not yet :-) depending on how we encode the model and whether we only encode the model there might be an initialization hit on first invocation to generate the bytecode, that could be ameliorated at link time and/or with Leyden. Details to be worked out?)

Could you please expand on how the scope broadens for the  final, or effectively final, variables in the lambda?

To be clear it *does not* broaden. e.g.,

final int i = a() + b();
@Reflect
Runnable r = () -> IO.println(i);

We don?t broaden the scope to reflect over the declaration of local variable i and its initializer expression.

?this" is a final variable that is captured. The fields themselves are not captured.

Paul.

As the PR title says.
Several methods in JavaType missing `@return`.

I've also tweaked the `typeVarRef` factory to just be called `typeVar` -- and also tweaked the javadoc accordingly.

Looks good.

I note you also removed some of the analyses (e.g. SSABraun).

This PR introduces the following ONNX updates:

- Added support for integer and string tensors.
- Enabled support for custom ops libraries.
- Fixed `OnnxLift` to properly lift models without initializers.
- `OnnxLift` now extracts only internally stored weights; external weights continue to reference the original data file.
- Explicit declaration of the `CLIPTokenizer` operation.
- Implemented the `SessionOption::bypassInitializers` switch to optionally exclude initializers from the generated model.

-------------

 - fixed lift of ONNX models with no initializers
 - fixed support of String tensors
 - Integer tensor fixes
 - added support for custom ops libraries
 - Support for int tensors
 - Initial support for String Tensors
 - OnnxLift and JavaTemplate updates:

This PR addresses javadoc warnings for missing comments in CoreOp and other classes such as ExternalizedTypeElement, Op, Interpreter.

In addition to the javadoc changes, there's two access changes I made:

* the constructor for VarLoadOp/VarStoreOp was exposed -- which seemed odd, as this was the only case where a core op had a public constructor
* the CoreOp constructors were protected -- I changed that to package-private. Since CoreOp is sealed, not much difference -- but, protected members do show up in the javadoc (and this seems uninteresting)
* Interpreter has an helper function eraseAndThrow which was (I think) accidentally made public
