"Now if someone could loan me a z15 or z16 we might be able to try this outselves. :-)" Once upon a time IBM would do this, maybe not a z15 but a z16 if the project was viable. for 2 POC projects I was involved in we used a 4340 or a 41 I forget, as a CADCAM  CATIA processor

Seems we may be closer than we thought to getting this done. There is already a whole chapter in the CP Planning and Administration Guide (Chapter 17. Using PCIe Functions for z/VM Guests) showing how to set up a device on the PCI.e bus. Now if someone could loan me a z15 or z16 we might be

Many thanks for sharing everyone's thoughts on this matter. I think that there are a lot of applications that could benefit from having access to the capabilities of a GPU or two (or ten:-), maybe not as a replacement or competitor for large Intel-based supercomputers, of course.

"Funny you should mention it." On April 5, 2022, IBM announced the IBM z16 with new IBM Telum Processors. Every main processor chip on the IBM z16 is equipped with a new AI accelerator section. Here's the list of operations supported on the AI accelerator: LSTM Activation GRU Activation Fused

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,

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

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
