Abstract

A multiprocessor computer system facility is provided for selectively reallocating a logical processing unit within the computer system. The logical processing unit is one logical processing unit of multiple logical processing units backed by a socket of a plurality of sockets of the multiprocessor computer system. The selectively reallocating includes: monitoring, during execution of program code of the multiple logical processing units, a performance metric of a hardware resource of the socket, the hardware resource being shared by the multiple logical processing units; and reassigning the logical processing unit, based on the monitoring, to a different socket of the plurality of sockets of the multiprocessor computer system to, in part, improve the performance metric of the hardware resource of the socket.
