Speaker: Dr Tom Deakin, University of Bristol Slides: https://hpc.fau.de/files/2025/07/25_07_15_cpp_is_nearly_all_you_need.pdf Abstract: To write an HPC code, we use a serial programming language… C++ is (nearly) all you need for HPC

C++ is (nearly) all you need for HPC. Catch up on the talk I gave at an online seminar at Erlangen National High Performance Computing Center (NHR@FAU) at the Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU)

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!

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.

#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.

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.

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.

#HPC

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.
