-hInstead of mean memory size, show the fraction of total available CPU time consumed by the process during its execution. This ``hog factor'' is computed as (total CPU time)/(elapsed time).
-kInstead of memory size, show total kcore-minutes.
-mShow mean core size (the default).
-rShow CPU factor (user time/(system-time + user-time)).
-tShow separate system and user CPU times. The number of blocks read or written and the number of characters transferred are always reported.
