High Performance Computing (HPC) Chips – A Veritable Smorgasbord?
No this isn't about the song from Charlotte's Web or the Scandinavian predilection for open sandwiches; it's about the apparent newfound choice in the HPC CPU market.
For the first time since AMD's ill-fated launch of Bulldozer the answer to the question, 'Which CPU will be in my next HPC system?' doesn't have to be 'Whichever variety of Intel Xeon E5 they are selling when we procure'.
In fact, it's not just in the x86 market where there is now a genuine choice. Soon we will have at least two credible ARM v8 ISA CPUs (from Cavium and Qualcomm respectively) and IBM have gone all in on the Power architecture (having at one point in the last ten years had four competing HPC CPU lines – x86, Blue Gene, Power and Cell).
In fact, it may even be Intel that is left wondering which horse to back in the HPC CPU race with both Xeon lines looking insufficiently differentiated going forward. A symptom of this dilemma is the recent restructuring of the Xeon line along with associated pricing and feature segmentation.

Nah, RISV-V will end up like the Motorola 88000, after some initial noise it'll fade slowly into oblivion, accompanied by the sound of no-one caring.
And I don't mean that as a snarky comment, it's an also-ran with no support infrastructure outside of one or two obscure vendors, why would a device designer go with one of these? You're betting your product, and possibly your company, on a barely-there product that may not exist next month. There's no way I could convince any of my mgt to go with something like this for anything outside of a hobby project done on my own time.

RISC-V is something that will grow from niche to mainstream.
You fuckers are always trying to imagine lucrative ventures, but that's not where this will start. As always, it will start in hackers' proverbial garages.
