* **Introduction**
The intelligent computing ecology is mainly composed of
middleware/framework + tool chain + hardware. Each vendors build
corresponding tool chain around its own hardware, and generates branch
version matching different AI framework.
The ecosystem is becoming diverse, cross-architecture and cross-stack
migration of upper-layer applications is extremely complex, which brings
development challenges to application developers, computing force
service providers and chip vendors.
In order to facing ecological challenges, we proposed a technology named
Heterogeneous-Accelerator Migration Technology , the goal of which is to
break the existing compile-link-execute tightly coupled tool chain
ecology, establish a new collaboration mechanism.Shield the underlying
hardware differences, and realize cross-architecture non-sensing
migration and execution of applications. Build traction model of the
intelligent computing industry chain with software as the core, and
prosper the ecology of intelligent computing industry.
The Heterogeneous-Accelerator Migration Technology architecture mainly
consists of two layers: the heterogeneous-accelerator migration
abstraction layer and the computing force pooling layer. Among them, the
heterogeneous-accelerator migration abstraction layer mainly includes
native interfaces based on a unified programming model and converters,
as well as a hardware-native stack formed by a cross-architecture
comprehensive compiler and runtime, generating a unified executable
program format. The computing force pooling layer mainly consists of
components for heterogeneous computing power registration management,
scheduling, and pooling, achieving unified management and pooled
execution of heterogeneous computing power resources.
