Based on next-generation AMD CDNATM 3 architecture, the AMD InstinctTM MI300A accelerated processing unit (APU) is designed to deliver outstanding eficiency and performance for the most-demanding HPC and AI applications.

2025年2月9日 · In MI300A - the AMD “Zen” 4 EPYC™ cores and third generation CDNA™ compute units share the same high-bandwidth memory (HBM). The MI300A implements the unified memory model by copackaging the CPU and GPU cores and directly attaching the CPU cores to the GPU’s infinity fabric memory architecture.

AMD Instinct MI300A accelerated processing units (APUs) combine the power of AMD Instinct accelerators and AMD EPYC™ processors with shared memory to enable enhanced efficiency, flexibility, and programmability.

2025年1月18日 · AMD’s MI300A does not advertise atomics support. However, it works well enough for me to adapt my core to core latency test to run with one GPU-side thread and one CPU-side thread. The GPU kernel uses OpenCL’s atomic_cmpxchg , while the CPU thread uses _InterlockedCompareExchange on Windows/MSVC or __sync_bool_compare_and_swap on …
