    I’m increasingly convinced that future CPUs will be judged not by traditional FLOPS or iOPS metrics, but by aggregate transactional memory operations retired per second. All microarchitectural optimizations should be directed to this end.

        Because Twitter took down their open verification process and the only way to get verified now is to ask for a favor from a crony at Twitter, which I won’t do.

        Last I checked they still hadn’t invented the components needed to implement large scale digital circuits.

        Are you speaking to software transactional memory or do you see hardware transactional memory becoming more mainstream? Do you engines leverage this? std::atomic?

        Nobody has yet created an STM implementation that using many cores beats a normal memory system running on one core without the overheads. So a pure unbounded HTM solution may eventually win, or else perhaps there is a middle ground.

        Going deeper, its about time to change curriculums to start teaching programing with concurrency first.

        I don't have a clue when. But I think the future of PC hardware is the GPU, CPU and maybe RAM on the same card. Or Phase RAM is also the hard drive. Then the joke of downloading more RAM becomes more relevant.
