Rex, on a z15 there is an "Integrated Accelerator for Z Sort" which has nothing to do with zIIPs or general CPs.
From an IBM Redbook - IBM z15 (8561) Technical Guide IBM Integrated Accelerator for Z SORT Sorting data is a significant part of IBM Z workloads including batch workloads, database query processing, and utility processing. The amount of data stored and processed on Z continues to grow at a high rate driving an ever-increasing sort workload. IBM z15 processor adds special hardware to significantly accelerate frequently used functions. The IBM Integrated Accelerator for Z sort has been implemented on each core and it provides new architected instructions for sorting data to speed up sorting operations. It supports multiple active sorts in parallel and it is designed to: • Optimize elapsed time and CPU time • Shorten the batch window (primarily targeting existing batch type sort workloads • Improve select database functions, such as reorganization to help reorganize data more frequently as sorted data is faster to access in interactive use Paul Feller GTS Mainframe Technical Support -----Original Message----- From: IBM Mainframe Discussion List <IBM-MAIN@LISTSERV.UA.EDU> On Behalf Of Pommier, Rex Sent: Monday, April 4, 2022 3:22 PM To: IBM-MAIN@LISTSERV.UA.EDU Subject: non Db2 DFSort and zIIP question [EXTERNAL] Hello list, The subject line summarizes my question. We're running a z14 (so the SORTL stuff doesn't apply according to the doc I've read) and z/OS 2.4. Does DFSort support offloading to a zIIP processor for non Db2 sorting? I know I could purchase db2sort which is Syncsort under the covers for db2 sorts but I'm wondering about regular batch EXEC PGM=SORT usage of DFSort. I found a hit from about 8 years ago where at that point they didn't exploit a zIIP but was wondering if anything has changed. On a second subject, if we ever migrate beyond the z14, is the SORTL stuff available on the z15 and above (presumably) using zIIP or is it merely doing other acceleration on the general purpose engines?
