No, it is not a new Vector facility, kind of, it is similar, but not true Vector.
I think I am stating things correctly. Give me a few minutes to find your answers, because it is documented, it was some of the things I learned from the IBMTechU conference I went to a couple of months ago. From a presentation: The IBM z13 continues to support the z Integrated Information Processor (zIIP) which can take advantage of the optional simultaneous multithreading (SMT) technology capability. SMT allows up to two active instruction streams per core, each dynamically sharing the core's execution resources.

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
