Charles, Like Bill explained in his reply, the time reported is the time your program spent in execution regardless of how many processors it was dispatch on.

Noal Senior Technical Engineer Office: (408) 970 - 7978 -----Original Message----- From: IBM Mainframe Discussion List [mailto:[EMAIL PROTECTED] On Behalf Of Charles Mills Sent: Thursday, March 29, 2007 4:08 PM To: IBM-MAIN@BAMA.UA.EDU Subject: Re: What's a CPU second? Gee, thanks everybody for telling me about MP overhead and SRB time and time-slicing and the rationale for MSUs. <g> Would someone care to go out on a limb and give me a direct yes or no on my basic question? If a jobstep is reported to have used .02 CPU seconds, for example, that means it spent .02 seconds executing on one CPU, or a total of .02 seconds spread across multiple CPUs -- the number reported is irrespective of the total MSU horsepower of the box, correct? Presumably on a faster CPU, it would use fewer seconds -- but not fewer on a box rated at more MSUs due to more CPUs of the same speed. Is that right (neglecting MP overhead, marketing MSUs, SRB time, etc., etc.)?
