NVIDIA compiler engineers have spent the past several months working on a proposed GCC option -flto-partition=locality for having the compiler optimize the code layout for locality between callees and callers as part of the link-time optimization (LTO) process. For some workloads NVIDIA is finding this -flto-partition=locality compiler option being of significant help for bettering the CPU performance...

One of the unexpected twists this year was after several years of AMD quietly funding the ZLUDA developer for enabling unmodified CUDA applications to run on AMD GPUs at near-native performance, the ZLUDA atop AMD HIP code was made available and open-source following the end of the AMD contract. But then later on that ZLUDA code was taken down at the request of AMD. Back in October ZLUDA then decided to pursue a new life as an open-source multi-GPU CUDA implementation with an emphasis on AI workloads. Now as a New Year's Eve surprise, ZLUDA v4 was released as the first step to that new codebase...
