Urgh, that is annoying.

There is a block button though that helped me last time.

cibuildwheel π is out! (3.1.4). A few nice things, like --clean-cache, Android fixes, and new versions of things like CPython 3.14rc2. Note for iOS on GHA/Azure, you need macOS-14, Microsoft broke macOS-15 images for iOS (WRT CPython's test runner, anyway) github.com/pypa/cibuild...

Performance portability layer gotta perform!

Axel Huebl @axccl.bsky.social · Aug 9

Please don't hate me, but I will publish a tiny proceedings paper in which I list a single CPU core not far from a full GPU, because I wanted to learn how bad/good our serial vectorization is before OpenMP and MPI parallelization.

I also want to do the cardinal sin of benchmark presentation, ok?!

The 13th MVAPICH User Group (MUG) Conference is coming up (Aug 18-20 in Columbus). It's a great event for focused technical presentations around MPI and network performance. Great speaker lineup too. Wish I could make it in-person, but virtual attendance is free
