AMD Instinct MI100

Today at SC20, AMD launched what it is boldly proclaiming as the world’s fastest HPC accelerator for scientific research with the AMD Instinct MI100. They may be correct as they claim this to be the first x86 server GPU to surpass the 10 teraflops (FP64) performance barrier. The company is combing the new GPUs with its 2nd generation AMD EPYC CPUs as well as ROCm 4.0 open software platform to hit impressive new numbers and to help researchers propel new discoveries ahead of the exascale era.

It is nice to see some competition move into the high-end GPU space. This space has been dominated by a single company for several years. AMD is moving into the space by leveraging its new AMD CDNA architecture for the AMD Instinct MI100 GPU and then combining it with its popular and high-performing AMD EPYC processors. This combination is said to provide up to 11.5 TFLOPS of peak FP64 performance for HPC and up to 46.1 TFLOPS peak FP32 Matrix performance for AI and machine learning workloads. The company also claims a nearly 7x boost in FP16 theoretical peak floating point performance for AI training workloads (compared to AMD’s prior generation accelerators) with its new AMD Matrix Core technology.

On top of the GPU news, the company is rolling out software for exascale computing with its latest AMD ROCm developer software. ROCm consists of compilers, programming APIs and libraries that helps exascale developers when they are creating high performance applications. The latest version, ROCm 4.0, is optimized for delivering high performance on MI100-based systems, such as PyTorch and Tensorflow frameworks.
