ISPC v1.32.0 is now available! Over the last two releases (v1.31 and v1.32), our main goal was full AVX10.2 and APX support, and now that work is now complete. Along the way we also added new standard library functions and fast-math modes. github.com/ispc/ispc/release…

This should help make getting setup to contribute, or to build ISPC with specific versions of LLVM much easier!

Everyone told me when I started this that Windows Docker containers on Windows were a pain in the ass. They were right. But I still did it. I'm happy to release the first version of a Dockerfile for setting up a build environment for ISPC and LLVM github.com/pbrubaker/ispc-do…

New device names acm-g10, acm-g11, and acm-g12 were added for Intel® Arc™ Graphics. The dg2 device name has been removed. Performance on Xe targets has been improved significantly by analyzing and automatically reducing register spilling. 🧵5/6

We added a link mode to ISPC, enabling linking several LLVM bitcode or SPIR-V files while outputting LLVM bitcode or SPIR-V as a result. ispc link test_a.bc test_b.bc --emit-spirv -o test.spv The CMake utilities were also updated to support the ispc link feature. 🧵6/6

It's my birthday! Technically, it was on June 21, but today is the day my dad, Matt, established my Twitter account. A BIG shout out to him for creating me back then, but he's not on Twitter! Only 11 years old, and I'm in video games, movies, streaming, creator software & more!

ISPC is a backend target for an OSS data-parallel functional programming language called Futhark by the Department of Computer Science at the University of Copenhagen, and many contributors. A link to the commit is in the post, but check out the main repo for docs & examples!

Replying to @ispc_updates
@pemathedev, myself and two others have used ISPC as a code generation target for the Futhark language: github.com/diku-dk/futhark/c…. We have also written a thesis about our findings which we are allowed to share in a couple of weeks

Still experimental; performance is a bit all over the place. Good foundation for future work. Closes #733.
