- _s_s_u_s_a_g_e is a SpeedShop executable that runs a process from the given
- command and arguments, and prints out a summary of the resources used
- during the run. It is used in exactly the same way as time(1), but
- prints additional information.
-
- The usage information is printed to stderr in the form:
- 1.89 real, 0.04 user, 0.29 sys, 15 majf, 2 minf, 0 sw, 1 rb, 0 wb, 21 vcx, 38 icx 854, mxrss
-
- The real, user, and sys fields give the real-time, user-CPU time, and
- system-CPU time, respectively.
-
- majf gives major page faults, _i._e., those causing physical I/O.
-
- minf gives minor page faults, _i._e., those requiring mapping only.
-
- sw gives process swaps.
-
- rb and wb give physical blocks read and written, respectively. Note that
- these are attributed to the process which first requests a block, but do
- not necessarily directly correlate with the process' own I/O operations.
-
- vcx gives voluntary context switches, that is, those caused by the
- process' own actions.
-
- icx gives involuntary context switches, those caused by the scheduler.
-
- mxrss gives the maximum resident set size of the program, including any
- shared pages, in kilobytes.
-
- In addition, if the command terminates abnormally, a message to that
- effect is printed before the usage line.
