The relation between IRD and Hiperdispatch is mentioned in Hiperdispatch docs and in Katy's presentation: Hiperdispatch takes over (disables) IRD's Vary CPU management.
Kees. -----Original Message----- From: IBM Mainframe Discussion List [mailto:[email protected]] On Behalf Of Alvaro Guirao Lopez Sent: Wednesday, February 27, 2013 09:01 To: [email protected] Subject: WLM Intelligent Resource Director (was Defined capacity) Very interesting thread... casually I was reading about IRD when I saw this mail in my inbox :-))) For those who don't have the expert knowledge of Kees or Al. IRD uses facilities in WLM, Parallel Sysplex and PR/SM. Change the amount of system resources (central processors and channel paths) allocated to an individual LPARs, in order to better achieve overall goals for sysplex workloads. Basically provide an automated capability to dynamically move CPC hardware resource to where the current sysplex workload can best use it. More info: *"z/OS Intelligent Resource Director"* *"z/OS MVS Planning: Workload Management" - Chapter: "Defining the SYSZWLM_xxxxyyyy Coupling Facility Structure"** * * * * * I didn't see any shop with IRD, but seems that it's useful for large shops, with multiple LPARs in several Sysplex. How the results impact in LPAR performance doing this configuration? Any experiences? I didn't see any chapter about the relation between IRD and Hiperdispatch, meanwhile Hiperdispatch tries to assign 100% share LCP of a PCP to one LP, IRD is controling also the dispatching of LCP. Any comments? 2013/2/26 Mary Anne Matyaz <[email protected]> > I haven't been following this thread too closely, but I thought > perhaps a recent presentation could help.
