Abstract: Methods and apparatus to schedule operations in computing systems are disclosed. An example method includes determining, by executing an instruction with a processor, that an operation identifier is inactive, the operation identifier assigned to a first operation, the operation identifier utilized by the processor to allocate computing resources of a computing system to the first active operation and in response to a request for assignment of an operation identifier to a second operation: freeing, by executing an instruction with a processor, the operation identifier from the first operation, and assigning, by executing an instruction with a processor, the operation identifier to the second operation.

Abstract: Various systems and methods for authenticating a user are described herein. A system to includes a biometric scanner to scan an input sequence of biometric identifiers; a storage device to store a biometric identifier database; an input module to receive the input sequence of biometric identifiers; an access module to access the biometric identifier database and retrieve a secret sequence of biometric identifiers; a comparator module to compare the input sequence of biometric identifiers to the secret sequence of biometric identifiers to obtain a result; and an authorization module to, based on the result, allow access to a resource provided by the system.
