Abstract
The present disclosure relates to sharing a context on a coherent hardware accelerator among multiple processes. According to one embodiment, in response to a first process requesting to create a shared memory space, a system creates a shared hardware context on the coherent hardware accelerator and binds the first process and the shared memory space to the hardware context. In response to the first process spawning one or more second processes, the system binds the one or more second processes to the shared memory space and the hardware context. Subsequently, the system performs one or more operations initiated by the first process or one of the one or more second processes on the coherent hardware accelerator according to the bound hardware context.
