> I'm somewhat curmudgeonly w.r.t. SVE, insisting that while the sole system in existence is a HPC machine from Fujitsu, that for practical purposes it doesn't really exist and isn't worth learning. I will likely revise this opinion when ARM vendors decide to ship something (likely soon, by most roadmaps).
Fair enough. I have high hopes for SVE, though. The first-faulting memory ops and predicate bisection features look like a vectorization godsend.

I'm still going to attempt a nerd-sniping with the published architecture manual. Fujitsu includes a detailed pipeline description including instruction latencies. Granted its just one part, and its an HPC-focused part at that. But its not every day that this level of detail gets published in the ARM world.

SVE is blessedly uniform in this regard.

This goes both ways, though. A64FX has two vector execution pipelines and one dedicated predicate execution pipeline. Since the vector pipelines cannot execute predicate ops, I expect it is not difficult to construct cases where code gets starved for predicate execution resources.

The A64fx also has hardware synchronization barriers to synchronize cores, which is a pretty GPU-like thing (at least it is very common on GPUs, and rare on CPUs).
