A method and system for handling a management interrupt, such as a system management interrupt (SMI) and/or a platform management interrupt (PMI), includes allocating two or more processor cores from a plurality of processor cores to form a group of management interrupt handling processor cores. Generated management interrupts are directed to this first group of processor cores and not to remaining processor cores, which form a second group. At least one of the processor cores in the first group handles the management interrupt without disrupting the current operation of the processor cores in the second group.
