A system, method, and computer program product are provided for improving resource utilization of multithreaded applications. Rather than requiring threads to block while waiting for data from a channel or requiring context switching to minimize blocking, the techniques disclosed herein provide an event-driven approach to launch kernels only when needed to perform operations on channel data, and then terminate in order to free resources. These operations are handled efficiently in hardware, but are flexible enough to be implemented in all manner of programming models.
