Exemplary methods, apparatuses, and systems receive a first instruction set from a first virtual machine (VM), the first instruction set including a request to perform an operation on an input. A first identifier is generated based upon the operation and the input. The first identifier is mapped to a stored copy of the input, the operation, and an output resulting from a processor performing the operation. In response to receiving a second instruction set from a second VM, a second identifier is generated based upon the input and operation received within the second instruction set. In response to determining that the second identifier matches the stored first identifier, it is further determined that the input and operation of the first instruction set matches the input and operation of the second instruction set. A copy of the stored output is returned to the second VM.
