Software definition server system and method for heterogeneous computing

Abstract

The invention discloses a software definition server system and method for heterogeneous computing. A software definition heterogeneous multiprocessor system comprises a universal processor, a heterogeneous computing processor, a software definition controller and peripheral equipment. The universal processor is used for executing the tasks of a control plane, wherein the tasks comprise the steps of executing a control process of a parallel program, initially configuring the multiprocessor system and providing universal computing capacity. The heterogeneous computing processor (like a GPGPU and other processors) is used for executing the computing task of the parallel program; the software definition controller is used for carrying out data exchange on a data plane between all parts (including the universal processor, the heterogeneous computing processor and the peripheral equipment) in the multiprocessor system; the peripheral equipment comprises an internal storage device (like a DRAM), a storage device (like a disk) and a network device (like a network interface card), and the like.

Description

technical field [0001] The invention relates to the field of parallel multiprocessor systems, in particular to a software-defined server structure oriented to heterogeneous computing. Background technique [0002] The current mainstream servers are mostly SMP and ccNUMA structures, using chipsets (Chipsets) to realize the interconnection between processors and peripheral devices in the server, and heterogeneous computing processors (such as GPGPU, Intel Xeon Phi, DSP, etc.) Coprocessors are classified under the category of peripherals (peripheral computing devices). In this structure, the interconnection topology between the general-purpose processor and peripheral devices adopts a tree structure, the general-purpose processor is located at the root of the tree topology, and the peripheral devices are located at the leaves of the tree topology. However, the leaf (peripheral device) can only exchange data with the root (general-purpose processor), and the data exchange betwe...

Problems solved by technology

This structure limits the efficiency of data exchange between heterogeneous computing processors and between heterogeneous computing processors and peripheral devices, that is to say, the traditional server structure is not suitable for application in the field of heterogeneous computing

[0003] In addition, as the types of heterogeneous computing processors increase, different types of heterogeneous computing processors are suitable for different computing modes (eg, GPGPU is suitable for large-scale streaming data processing, network processors are suitable for network data processing, DSP is suitable for signal processing), which makes the co-processing mode between processors more complex. The complex co-processing mode requires data to be efficiently and flexibly transmitted between processors, that is, data can be directly transmitted between any two processors
