Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATION
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 14:
15. A computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a computer to cause the computer to perform operations comprising:
in response to monitoring a processor during operation, detecting, by the computer, a first number of core recovery events in the processor;
determining, by the computer, that the first number of core recovery events fulfills a first condition for a first core recovery events threshold, a core recovery event in the first number of core recovery events corresponding to setting a core of the processor into a successful architectural state;
in response to fulfilling the first condition, modifying, by the computer, a value of at least one droop sensor parameter of the processor by a first amount, the at least one droop sensor parameter affecting a sensitivity to a voltage droop;
in response to modifying the value of the at least one droop sensor parameter by the first amount, detecting, by the computer, a second number of core recovery events in the processor;
determining, by the computer, that the second number of core recovery events fulfills a second condition for a second core recovery events threshold; and
in response to fulfilling the second condition, modifying, by the computer, the value of the at least one droop sensor parameter of the processor by a second amount.
