Abstract: A processing unit (e.g., a CPU) executes multiple processes, such as multiple virtual machines, wherein each process employs virtual signals and virtual signal monitors to support signaling between the process and one or more accelerators. A hardware signal manager (HSM) assigns each virtual signal to a physical signal of the system and assigns each virtual signal monitor to a physical signal monitor. Based on a process' interactions (e.g., signal operations) with a virtual signal monitor, the HSM executes corresponding interactions at the assigned physical signal monitor. The HSM thus virtualizes the physical signal monitors for the executing processes.
