The first place to look is the IBM z13s Announcement Letter about "Simultaneous Multi-Threading (SMT)" and search IBM.com with "Simultaneous Multi-Threading (SMT)", to find a lot and it is not just z/OS.
An additional resource is: 5697-AB1 IBM Automatic Binary Optimizer for z/OS V1.1, this product updates COBOL LOAD libraries to take advantage of the newer processors, without having to recompile or upgrade to COBOL 5.2, which has the support for SMT built in: https://www-01.ibm.com/common/ssi/cgi-bin/ssialias?infotype=DD&subtype=SM&htmlfid=897/ENUS5697-AB1 Redbook: z Systems Simultaneous Multithreading Revolution http://www.redbooks.ibm.com/abstracts/redp5144.html?Open Al Nims Systems Admin/Programmer 3 UFIT University of Florida (352) 273-1298 -----Original Message----- From: IBM Mainframe Discussion List [mailto:[email protected]] On Behalf Of Ed Jaffe Sent: Monday, July 18, 2016 1:24 PM To: [email protected] Subject: Re: Any Gotchas going from V1.13 to V2.2 On 7/18/2016 10:02 AM, Tom Marchant wrote: > On Mon, 18 Jul 2016 14:17:17 +0000, Nims,Alva John (Al) wrote: > >> [On] a z13 system, there are new hardware instructions that use the >> zIIP engines > What does that mean, Al?

Of course, those instructions work on all PU types. -- Edward E Jaffe Phoenix Software International, Inc 831 Parkview Drive North El Segundo, CA 90245 http://www.phoenixsoftware.com/ ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
