Does ATI Radeon HD5750 OpenCL supports cl_khr_byte_addressable_store?

[Feng]

I'm new to Scala and OpenCL, so I Decided to Kill Two Birds with one stone and try to ScalaCL. I Could setup NetBeans 6.8 is My MacBook Pro with Mac OS X 10.6.3. When I compile the ScalaCL Test example, goal When It Came to run it, I got the following error :

# Pragma OpenCL EXTENSION cl_khr_byte_addressable_store: require 
__kernel void function (__global float * out) ( 
Dim1 get_global_id int = (0); 
out [Dim1] = (null) + (null); 

)

Does anyone Has An Idea What Is Happening here?? Please help me.!!

You know that it is mandatory to code on CUDA SDK. OpenCL for this OpenCL SDK from nVidia, just gives the tools to make the best of OpenCL compatible with the equipment nVidia Cuda (the only consistent OpenCL). Going through what is available in XCode anyway it will work with compatible cards OpenCL (ATI / AMD and Nvidia), here is to push further optimization.

I am Assuming the code you are running IS compiled at run time. The Reason I Suggest Some graphics cards then this is it Macs (27 iMac, fall 2009 and others) Have drivers for ATI graphics cards do not That Fully OpenCL support. In this case you could compiled for a CPU device, (with CL_DEVICE_TYPE_CPU) to move forward Until ATI releases driver updates OpenCL work.

Your error looks like There's An outcome in ScalaCL (generate bad code OpenCL). Anyway you have not mentioned the version that you are using. Which version are you using? If You Did not build from sources ScalaCL, Maybe There's A Mismatch Between the example (taken from SVN) and Your ScalaCL JAR (taken from binary downloads?). To build JavaCL Demos, just cd to the libraries/OpenCL/Demos directory and run the following command (works the same for any other sub-project) :

mvn clean install

To avoid launching tests, you can append a -Dmaven.test.skip=true argument to that command.

I Have now compiles ScalaCL from SVN sources. When I run ScalaCLTest, I Now get this error message :

Exception in thread "main" java.lang.SecurityException: Invalid
Signature file digest for Manifest attributes hand

After much searching I came to know about the problem. his can Be Caused By An incomplete build from sources: If You Did not run "Mvn install" from the top "libraries" directory, with the freshly built files, unsigned. I am sure this would be the same problem for you.
