[...] Indeed. But while the .pdf mentions Posits and Valids, the following slides only discuss Posits. Where's the discussion on Valids? In spite of that, though, Posits appear to be a much better candidate at replacing IEEE 794 floats than the previous unum incarnations. I felt the previous incarnations, while clever and workable in theory, posed too many practical challenges to implement on silicon. The current description of Posits seem to be much more feasible to put on silicon. Still, though, I wonder what Gustafson has up his sleeves wrt. Valids. In the Stanford presentation pdf, (note that these change from presentation to presentation) on page 12, is the only mention of Valids. I thought these were a rename of Sets of Real Numbers(SORNS) from his Type 2 Unums, but after reviewing the slides again, I'm not sure. I believe that this needs to be vertified with Dr Gustafson, as you correctly point out there are no examples of Valids. But when I review his slides from his New Zealand talk, there is an additional slide, where he states that (1) "Posit pairs beat intervals at their own games, too: Valid mode." and (2) "Posit mode: Round unum after every operation. Valid mode: rigorous answer bounds; NaN answers are sets. " If anyone wants a copy of these New Zealand slides, please advise me of your email address.

Update on Unums
Hi Everyone Here is an update on Unums. John L Gustafson at the Multicore World 2017 Conference, in Wellington, New Zealand, in February 2017, gave another presentation to his Unum idea. He has again reworked the basis of his idea again. He has now called this latest version: Type 3 Unums (2017), and introduced new labels of Posits and Valids for contrasting Calculation Esthetics. If I get the approval to post Johns latest presentation, I will do so. cheers Nick

Single-core performance of the HTTP server is improved by about +50% and multi-core performance scales properly again after excessive lock contention sneaked in in one of the previous releases. The number of worker threads is now also properly determined on all systems (including multi-CPU), which should fix the numbers for multi-threaded benchmarks (an update to the TechEmpower benchmark suite is on the way). I look forward to reading the numbers, and seeing how it compares, to other web servers :) Nick

However without actually implementing it my guess is as good as any. I would probably look at HHVM, and see what is easy to reimplement in D. So the best approach, if I understand you correctly, would be to perform micro-benchmarks on new code that is either D code (with a variety of algorithms and/or vibe.d framework code) or HHVM 64 bit code, and compare (and publish) the results ?

I just planned on PL/0 as input and C as output. It is a simple one-pass (okay 2 pass if you count the optimizer) trans-compilation. There is no middle-end. And very little verification. Everything that parses will produce an c-output. Which does may or may not compile. Since PL/0 just one type. Int you can get away with anything :) so could it be used to produce D output instead of C ? Could it be used to parse PHP as input ?
