Re: Is JES2 z22 mode required on z/OS 2.5?

Silly question: WHAT IS THE PROBLEM? What is the problem with migration to z22 mode? Yes, the migration is mandatory, so if some obstacles exist (do they???), then it is good time to remove them. -- Radoslaw Skorupka Lodz, Poland W dniu 19.08.2022 o 01:04, IBM user pisze: Hi Mark, Thanks

Once upon a time......

IBM was known for making some really nice scientific number-crunching systems. The 7090-7094, the S/360-195 and the follow-on s/370-195, the array processor 3838 and the vector instruction set supported by the 30xx models come to mind. Over time, and with the rise of the Intel-based chips and th

What gives you that idea? The 7090 and 7094 preceded the S/360, and the supercomputing link from that page lists machines back to 1954. Not that IBM was the only fish in that pond (-; -- Shmuel (Seymour J.) Metz http://mason.gmu.edu/~smetz3 From: IBM Ma

You would offload a lot of the (expensive) Z cycles to the GPU, right? Still, I agree, hard for me to see this flying. It pains me to say this, but we just don't seem to hear people saying "I would love to put business process 'X' on the mainframe." Don't flame me -- I love the Z and the mainframe

Re: Once upon a time......

Actually "IEEE floating point" is rather specific. z-architecture now supports the original Hex Floating Point (HFP) data formats, plus the newer Binary Floating Point (BFP) and Decimal Floating Point (DFP) formats.  BFP is based on IEEE binary floating point standards, and should be compatible

Re: Once upon a time......

Correction: Just realized the z Decimal Floating point is also based on the IEEE 754 Standard as well, so "IEEE floating point" also includes decimal floating point and encompasses all the Decimal Floating Point formats and arithmetic instructions too.      Joel C. Ewing On 8/21/22 17:29, Joel

Maybe not for zOS, but I personally think Linux on Z (with DPM fully "featured out" for automatic machine management) can be a beast. If only IBM or independent reviewers ran actual comparisons of costs, density, etc. zDNN on z16 chip is "ok", but do note that this is again a whole bunch of year
