GCC 15 Now Enables AArch64 Early Scheduling For -O3/-Ofast Modes

7 mars 2025 à 15:13
The GCC "-fschedule-insns" option allows for reordering of instructions to eliminate execution stalls when required data is unavailable. This early scheduling option can be beneficial for systems with slow floating point performance or costly memory load instructions. With the upcoming GCC 15 release, AArch64 will be enabling this early scheduling optimization at the -O3 optimization level and higher...

Unofficial ROCm SDK Builder Expanded To Support More GPUs

7 mars 2025 à 13:40
The community-based ROCm SDK Builder is an unofficial project leveraging the open-source AMD ROCm code and making it easy to build machine learning and GPU compute software across a range of environments and helping ensure proper integration with other machine learning tools and models. The ROCm SDK Builder takes special focus on the consumer Radeon iGPUs and dGPUs that typically aren't as much of a focus for the upstream AMD ROCm stack...
