Data Processing Unit
Vorlage:Short description Vorlage:Sources exist Vorlage:Advert
A data processing unit (DPU) is a programmable computer processor that tightly integrates a general-purpose CPU with network interface hardware.[1] Sometimes they are called "IPUs" (for "infrastructure processing unit") or "SmartNICs".[2] They can be used in place of traditional NICs to relieve the main CPU of complex networking responsibilities, which can otherwise introduce significant overhead in cloud computing environments.[1]
The data acceleration engine differentiates itself from a CPU by a larger degree of parallelism (required to process many requests) and from a GPU by a MIMD architecture rather than an SIMD architecture (required as each request needs to make different decisions and follow a different path through the chip).[3][4] DPUs can be either ASIC-based, FPGA-based or SoC-based.[5] DPUs have been increasingly used in data centers and supercomputers since their introduction in the 2010s due to the rise in use of data-centric computing, big data, security, and artificial intelligence/machine learning/deep learning.[6] DPUs are designed to be independent infrastructure endpoints.[7]
