Exactly right John. Why would anyone want to *run* blockchain on z/OS? Linux on z makes alot more sense. *Using* blockchain from z/OS applications is a different story. Kirk Wolf Dovetailed Technologies http://dovetail.com On Fri, Oct 20, 2017 at 12:28 PM, John McKown <john.archie.

Re: Blockchain

Todd, I don't see SHA-512 CPACF number in the paper that you reference. I can't find any benchmarks for z13 CPACF. For non-specialized hardware, (like GPUs): https://en.bitcoin.it/wiki/Non-specialized_hardware_comparison It looks here like an AMD Radeon 6970 will do around 400 million SHA-256

Re: Blockchain

Hi Todd, I know that SHA-256 is available in CPACF (and I've written Assembler code to use it).My assumption is that using Vector integer instructions to solve many hashes in parallel would be more efficient. CPACF SHA-256 (for one hash) is much better than equivalent GP Integer

Re: Blockchain

Kirk, you don't need to program the SHA-256 algorithm in software - it's available as a hardware instruction using CPACF. I don't have performance numbers handy for SHA-256, but you can see SHA-512 performance in this paper:
