 6 Function:  measures the speed of a processor by timing a series of code
 7 sequences.  The code sequences are chosen to test the more common and
 8 important sequences of instruction as well as to get a general idea of
 9 the limiting speed that can be expected.  It is generally useful to
10 select a processor (with the use of the set_proc_required command
11 described in System Diagnostic Aids, Order No.  AR97) before running
12 timing tests.

15 Control arguments:
16 -long, -lg
17    displays a histogram of MIP rate for 100 passes of each code
18    sequence.

21 Notes:  Code sequences that take longer than expected, probably due to
22 interrupt or fault action, are factored out and not counted.
