Abstract
Examples provide a method of virtualizing a hardware accelerator in a virtualized computing system. The virtualized computing system includes a hypervisor supporting execution of a plurality of virtual machines (VMs). The method includes: receiving a plurality of sub-programs at a compiler in the hypervisor from a plurality of compilers in the respective plurality of VMs, each of the sub-programs including a hardware-description language (HDL) description; combining, at the compiler in the hypervisor, the plurality of sub-programs into a monolithic program; generating, by the compiler in the hypervisor, a circuit implementation for the monolithic program, the circuit implementation including a plurality of sub-circuits for the respective plurality of sub-programs; and loading, by the compiler in the hypervisor, the circuit implementation to a programmable device of the hardware accelerator.
