Computers, Hiking, Music, and Coffee, oh my! Opinions are mine, though #iamintel.

@FelixCLC_ @illuhad @ProjectPhysX PVC should "just work" with >4GB allocations, no special steps required. If it doesn't, please file a bug or otherwise let us know - thanks!

[Ben Ashbaugh @bashbaug]

@FelixCLC_ @illuhad @ProjectPhysX Note, the maximum allocation size is the same for both our OpenCL and Level Zero drivers. The reason why >4GB allocations work through the DPC++ runtime is because it explicitly relaxes the allocation limits.

[Ben Ashbaugh @bashbaug]

@ProjectPhysX @illuhad @FelixCLC_ Yeah, you would also need to tell the compiler allocations may be >4GB. Have a look at: https://t.co/AiktifwZ1T

[Ben Ashbaugh @bashbaug]

@illuhad @FelixCLC_ Our current client GPUs report a 4GB limit because it lets us use 32-bit addressing arithmetic more aggressively, which improves performance. It's not something that's required by the spec.

[Ben Ashbaugh @bashbaug]

@illuhad @FelixCLC_ This matches my understanding as well. A 16GB card would need to support at least 1GB allocations, and could report up to 16GB (no upper limit). Only less-than-4GB cards could have a less-than-1GB allocation limit.

The call for submissions for the 11th International Workshop on #OpenCL and #SYCL closes on Friday Jan 20, 2023. Papers, tech talks and posters are all welcome. Join us in Cambridge, UK on April 18-20. https://t.co/hQ75ungIjZ @openclapi @thekhronosgroup @SYCLstd

[Ben Ashbaugh @bashbaug]

@ProjectPhysX @FluidX3D @IntelGraphics I've filed an internal issue regarding the incorrect queries. Should be an easy fix. Feel free to file an issue on the compute-runtime GitHub also if you'd like. Thanks for raising these issues!

[Ben Ashbaugh @bashbaug]

@ProjectPhysX @psychocoderHPC @FelixCLC_ @SquashBionic @TheMalcore @AMD Following up: Linux should be much better with the latest drivers. I see 15+GB reported on my 16GB GPU. Windows still needs some work though and I don't have an ETA at this time.

I missed seeing everyone at the @thekhronosgroup face-to-face meeting this week but I guess attending remotely had some benefits? #opencl #sycl #kittiesofkhronos

Cool, this is my alma mater. Go Tritons! #oneAPI #USCD

If you need help debugging and tracing your command buffer applications, the OpenCL Intercept Layer has full support for both the base command buffer extension and the mutable dispatch extension. https://t.co/jFxEM4AmoH #OpenCL

[Ben Ashbaugh @bashbaug]

Want to experiment with the new command buffer mutable dispatch extension right away? My command buffer emulation layer now supports this extension and should work with most OpenCL implementations. https://t.co/M4m3LVSGyr #OpenCL

[OpenCL API @openclapi]

OpenCL 3.0.12 Released With Command Buffers Mutable Dispatch Extension and Enhanced Layers Support

https://t.co/Pkef6vbmS5

[Ben Ashbaugh @bashbaug]

I also recently added command buffer emulation layer support for out-of-order command buffers for OpenCL implementations that support out-of-order queues. The same repo has sample applications that demonstrate how to use both new features. #OpenCL

#OpenCL @openclapi 3.0.12 Published With Command Buffers Mutable Dispatch Extension

@stillpixel Haha, yeah. I was waiting for them to knock over my water and turn off my power strip just to prove me wrong!

[Ben Ashbaugh @bashbaug]

I’ve been back at work for two weeks and I’m happy to report the new office assistants are working out great.

[Phoronix @phoronix]

There's room for better GL/VK perf (benchmarks next week), but as a developer card, the A380 at $139 is a bargain... @openclapi 3.0 on open-source stack, @IntelSoftware oneAPI ecosystem for testing and porting work is great, SYCL & rest of software ecosystem around it.

[Ben Ashbaugh @bashbaug]

Managed to squeeze in one last sabbatical hike before heading back to work next week. #desolationwilderness

[Ben Ashbaugh @bashbaug]

@stillpixel We went down the coast so sadly we were too far west. Next time (if it’s still there)!

Epic road trip complete! 5000 miles, 34 nights (32 in a tent), 9 national parks, one flat tire 😥, countless memories. Pic from yesterday at Crater Lake.
