SK Hynix announced that its Heterogeneous Memory Software Development Kit (HMSDK), designed to optimize compute express link (CXL) memory, is now integrated into Linux, the world’s largest open-source operating system. CXL technology enables efficient data transfer between CPUs, GPUs, and memory in high-performance computing, increasing memory capacity more than tenfold.
HMSDK improves memory bandwidth by over 30% without altering applications and boosts system performance by 12% through access frequency-based optimization. By moving frequently accessed data to faster memory, the tool enhances the performance of systems using next-generation AI memory like CXL, which is seen as the successor to high bandwidth memory (HBM).
This development positions SK Hynix for future global collaboration, as Linux developers can now utilize its software as an industry standard for CXL memory. The semiconductor industry anticipates CXL’s full-scale commercialization in late 2024, with SK Hynix planning mass production of its 96GB and 128GB CXL 2.0 memory modules by year-end, aligning with the launch of CXL 2.0-powered server CPUs.
