+Some kernel parameters take a list of CPUs as a value, e.g.  isolcpus,

-Note that for special case of range one can split range into equal size of groups
-and for each group to use some amount form the begin of that group.
-<cpu number>-cpu number>:<used size>/<group size>
-For example one can add to its command line following parameter:
-isolcpus=1,2,10-20,100-2000:2/25
