Abstract
A computer-implemented method, computer system and a computer program product schedule a secure code segment on a processor core of a processing unit between threads, wherein the processing unit is executing a program code of operating instructions of a thread on the at least one processor core. The method comprises a first thread requesting exclusive secure execution of a secure code segment of the program code on the at least one processor core. The method also comprises checking the request based on a secure-operation parameter that controls a request for exclusive secure execution of a secure code segment. The method further comprises, if the secure-operation parameter is below a predefined threshold value, setting the at least one processor core to exclusive secure execution for the secure code segment and periodically resetting the secure-operation parameter. If the secure-operation parameter is not below the threshold, then the method switches to another thread.
