So long #ISC25!

All things, with one exception, have to end After years of sharing #HPC news and insights, it's time to log off It was fun while it lasted and I remain grateful to all of you who followed and interacted Stay curious, stay kind! — @hpcguru.bsky.social signing off #HPC #Farewell

Cool to see two papers explore #SYCL performance on CPUs at #ISC25. It’s also great to see how much the performance has improved thanks to the commitment to the #oneAPI and #AdaptiveCpp implementations since we evaluated this a few years ago.

@nextsilicon.com has joined the OpenMP Architecture Review Board! Their Intelligent Compute Architecture brings new momentum to our mission: advancing open, portable, shared-memory parallelism. Welcome to the community! 🌍💻 #OpenMP #HPC #NextSilicon

Here at #ISC25 in Hamburg this week. I’ll be speaking about open standards at the Birds of a Feather Sessions (#OpenMP and #UXL Foundation) and sharing (alongside #NVIDIA) how to program GPUs with standard #C++. Looking forward to catching up with this great community. #HPC

The recordings and slides from the IXPUG 2025 conference are up! Some great talks to watch all about leveraging open standards for accelerated compute. www.ixpug.org/events/ixpug... #OpenMP #SYCL

At #IWOCL I had the pleasure of sharing the update from the #SYCL Working Group on all things SYCL past, present, and future.

See you at #IWOCL 2026! Keep an eye on iwocl.org for updates, and the archive for this and previous conferences. #OpenCL #SYCL

The #IWOCL 2025 Outstanding Full Paper Award Winner, Peter Thoman (UIBK) presents their work on optimising strided data movement across GPUs with Celerity and #SYCL

Just running compute with #SYCL is great but you always want to *SEE* the output. Duncan Brawley (Codeplay Software) is presenting interoperability for images with the DirectX and Vulkan Graphics APIs. #IWOCL

Virtual functions are important to C++ programs. Alexey Sachkov (Intel) proposes how #SYCL can by updated to remove the current restriction on this to make it work for those (like Kokkos) asking for it. #IWOCL

Next up at #IWOCL, Julian Oppermann (Codeplay Software) talks about fast compilation of #SYCL for code generated at runtime.

So you want to support #SYCL? We’re finding out on the last day of #IWOCL in the invited talk from Ben Ashbaugh (Intel) on his personal perspective for supporting SYCL with #OpenCL.

Wow, workshops are now included in the #SC25 technical program registration. This is incredible; workshops are an invaluable place to have focused, deeply technical discussion and build community with a high concentration of like-minded individuals. sc25.supercomputing.org/2025/04/work... #HPC

Workshops Are Now Included in Your Technical Program Registration • SC25

Thanks to attendee feedback, we're announcing an important and beneficial change to the SC25 registration categories.

More debugging talks at #IWOCL! This time for #OpenCL and #SYCL on CPUs where the code contains barriers. Presenting work from the team at Intel is Alexey Sachkov.

Tooling is a vital part of any programming ecosystem, and is particularly important for heterogeneous systems. Here at #IWOCL Rakesh Ganesh (Intel) shares work on debugging #SYCL on Intel GPUs in Visual Studio and VS Code.

Next up at #IWOCL, Aksel Alpay (Heidelberg University) talks about new Just-in-Time Optimisations in AdaptiveCpp for #SYCL. Ready to try in the latest compiler at github.com/AdaptiveCpp/...

Next up at #IWOCL, Moritz Heckmann (Saarland University) shows his approaches for implementing #SYCL sub-groups on CPUs.

The #SYCL backend to Kokkos was shared at #IWOCL last year, and Daniel Arndt (ORNL) is back this year to share experiences in targeting Frontier’s AMD GPUs with SYCL through Kokkos.

Alexey Sachkov (Intel) shares how they are working on SPIR-V backend support in LLVM towards a future where #SYCL can be supported upstream in LLVM directly. #IWOCL

Next, Alexey Sachkov (Intel) presents a vision for improving #SYCL compile times through changes to the SYCL header. #IWOCL
