Each fio job section will get unique CPU cores assigned based on the number of numjobs value. In case of high number of fio jobs or high numjobs parameter value we might eventually run out of CPU cores to assign. Allow regenerating list of available CPU cores. This allows to run the test, but as a result CPU cores might be shared between fio threads.
