Central Processing Unit and HPC

The Central Processing Unit (CPU) has been at the heart of High Performance Computing (HPC) for decades. However, in recent years, advances in parallel processing technology mean the landscape has changed dramatically. Modern Graphics Processing Units (GPUs), which feature 1,000s of compute cores and high capacity, high-bandwidth memory, have become extremely adept at processing massively parallel HPC code — delivering results very quickly. The GPU’s shift from dedicated graphics processor to powerful compute processor has been made possible by OpenCLTM,the open standard for parallel programming (recently updated to version 2.1).With OpenCL, HPC code can be optimized to run on virtually any processor, be it GPU, CPU, even a mobile processor. AMD offers a whole family of dedicated server-grade GPUs, designed specifically for heavy- duty compute operations. The AMD FireProTM S9150 server GPU, for example, can deliver exceptional processing power inside some HPE ProLiant servers and clusters. GPU compute touches many applications, from engineering analysis and seismic processing to medical imaging and ray trace rendering.
