Abstract: An apparatus includes a memory and one or more processors. The one or more processors are configured to receive a first computing task for execution, and, during execution of the first computing task (i) to monitor Operating System (OS) calls issued by the first computing task, (ii) to identify, based on the monitored OS calls, one or more outputs produced by the first computing task, and (iii) and to store the one or more outputs of the first computing task in the memory. The one or more processors are further configured to receive a second computing task for execution, and, upon ascertaining that the second computing task will produce at least one output that is identical to a stored output of the first computing task, to reuse the stored output of the first computing task as an output or the second computing task.
