(Advanced apologies for not knowing how to use code formatting here)
Thanks for the quick response.
It does not seem as though I have clinfo (or I don't know how to use it) despite the fact my lastest Nvidia drivers should have OpenCL included.
Other information:
- Windows 11 x64
- OpenJDK 17 from https://adoptium.net
I have run List<OpenCLPlatform> platforms = (new OpenCLPlatform()).getOpenCLPlatforms(); and it returns 0 meaning it does not appear to be detecting any OpenCL platforms on my PC. If the case were to be that there were no OpenCL platforms, then I am unsure how else I would go about installing it for an Nvidia GPU other than updating drivers.
@BlackHat0001 Another option is GPU-Z from here: https://www.techpowerup.com/download/techpowerup-gpu-z/
Hello, I came here half a year ago or so and was asking for help on getting set up with my 2014 macbookpro. I think we realized my computer was too old and not compatible. I've since upgrade to the new macbook pro that was just released (m1). I've tried this library but still got :
'''

SEVERE: Check your environment. Failed to load codegen native library or possibly failed to locate opencl native library (opencl.dll/opencl.so). Ensure that OpenCL is in your PATH (windows) or in LD_LIBRARY_PATH (linux).

Is there anything I can do? Or is the library just not compatible with the new macbook either?

@grfrost when you were helping me way back when you had me make a program called infocl.cpp which I ran and gave you the output of on my old mac. I've just done it on the new mac as well, and got this result:

Platform Apple

Tried the example repository and got the following:

It looks like the tag 3.0.0 of the example depends on aparapi 3.0.0-SNAPSHOT according to https://git.qoto.org/aparapi/aparapi-examples/-/blob/v3.0.0/pom.xml
but the README explains that if we use specific tags we don't need to install the jar ourself, right?
did a lit
pom.xml edit to make it depend on the regular 3.0.0 jar instead of the SNAPSHOT and tried again. Got some ugly errors:

note this part:
libaparapi.dylib' (mach-o file, but is an incompatible architecture (have 'x86_64', need 'arm64e')
if its really the case that this library is just not compatible with the new macs, maybe it should say so in the readme?
Until that becomes available
you would need to compile Aparapi-native project in ARM64 MacOS and then adjust Aparapi-JNI to detect ARM64 architecture on MacOS and load the appropriate dylib
finally, the generated aparapi-jni.jar could be used with Aparapi and should work on ARM64 MacOS too.
I try to stay on the java side, which is why this lib is so appealing!
@mgroth0 maybe you can try a x86_64 JVM with Aparapi
@freemo long time no see
Cannot invoke "com.aparapi.internal.model.ClassModel$AttributePool$CodeEntry.getExceptionPoolEntries()" because the return value of "com.aparapi.internal.model.ClassModel$ClassModelMethod.getCodeEntry()" is null
Any ideas why/how to fix?
I can give a full stacktrace or my code if that helps
Using 3.0.1-SNAPSHOT
Same thing on 3.0.0
@KrystilizeNevaDies the exception above seems to imply that there is no 'bytecode' associated with the 'run' method. This can happen if you dont have a run method on your kernel? Also if you have an abstract run method (expecting a superclass to implement it).
@mgroth0 as @CoreRasurae suggested you may have to be the M1 'leader' here ;) Unless you want to send one of us a shiny new laptop ;) Do you have xcode on your mac? If so I can probably walk you through the steps to build, but sadly it would require some basic knowledge of C++ compilation.
