Aggregate counts per processor socket for system-wide mode measurements. This Aggregate counts per processor socket for system-wide mode measurements. This
is a useful mode to detect imbalance between sockets. To enable this mode, is a useful mode to detect imbalance between sockets. To enable this mode,
use --aggr-socket in addition to -a. (system-wide). The output includes the use --per-socket in addition to -a. (system-wide). The output includes the
socket number and the number of online processors on that socket. This is socket number and the number of online processors on that socket. This is
