Ibm Z17 Time Synchronization Resiliency Enhancements

Given that, having to manage two layers of parallelism to maximize some super-expensive hardware seems like a non-starter whereas I think the appeal of zArchitecture is that you can use a set of well-developed tools and frameworks like DB2 and CICS to build a certain sort of application -- the early motivation for Sysplex was that IBM had to make a transition from bipolar to CMOS transistors and the first CMOS mainframes could not equal the performance of the biggest bipolar mainframes so they needed to get N CMOS mainframes to do the job of one bipolar where N is a small number.

The vision I do get out of this idea is some kind of system that has a very smart compiler that looks at things in a fractal manner, that is it knows you can apply SIMD to a calculation and then you can apply SMP to it, and then you can apply clustering techniques and who knows, a "cluster of cluster" might make sense for geographically distributed situations. I think of

but not so much the algorithm being oblivious but rather the compiler very much models opportunities to parallelism and the costs of moving data around so the applications developer can be "oblivious" about it all.
