According to embodiments of the present invention, machines, systems, methods and computer program products for processing events including efficiently processing interrupt service requests for peripheral devices, such as hardware accelerators, utilized in parallel processing are provided. For each core engine of a peripheral device, the peripheral device detects whether one or more interrupt signals have been generated. Information associated with the one or more interrupt signals are stored in one or more registers of peripheral device memory, for each core engine. The information is aggregated and stored in a vector of registers in the peripheral device memory, and the aggregated information is written to memory associated with a CPU to enable CPU processing of interrupt requests from each core engine of the peripheral device.
