Improving OpenCL On CPUs, Building Linux

Posted by Michael Larabel on June 17, 2012

Back in April there was an LLVM European Conference in London where several interesting technical discussions happened. Among the topics covered were auto-vectorization with LLVM, building Linux with LLVM, and using LLVM to improve the performance of OpenCL on CPUs.

The slides and videos of the two-day LLVM London conference were published a few weeks ago at LLVM.org. (I've just been a bit behind in catching up with the non-immediate news items for Phoronix and yesterday's writing of the Google C++ re-factoring reminded me to get out the rest.) For those into the LLVM compiler infrastructure, some of the interesting topics worth looking at the slides or videos would be:

- Argonne National Laboratory talking about auto-vectorization with LLVM (PDF).

- The Google engineer's plans to refactor C++ with Clang to make it more fun.

- The LLVM linker, lld. (PDF)

- Mark Charlebois talking again about building the Linux kernel with LLVM/Clang. (PDF)

- Work towards improving performance of OpenCL on CPUs. (PDF) This work comes out of Saarland University in Germany, the same place where the OpenCL LLVM back-end was born and a new BSD-licensed OpenCL driver.
