I'm really curious about the kind of software things like pacemakers run and potential implications from 32-bit time expiring.

I think Apple can get away with having their online store down for a few hours and not miss out on making money, unlike Amazon. Also as evidenced by this post it builds marketing hype.

The "limited availability" is almost certainly for those with per-arranged deals with Intel and 2H is almost always Q4. It's not to say this isn't an interesting product but I've a feeling Optane won't live up

It feels like Intel are putting this out in lieu of actual hardware. As always remain skeptical until real silicon appears on the market.

If you have corruption in RAID 1 how do you know which copy is good? On a slight tangent ZFS will checksum data and store that checksum in the block pointer (i.e. not with the data itself) so it can tell which of the copies is correct. The

For someone not really familiar with javascript could someone explain how sensitive information is removed from memory when no longer needed? Does the runtime expose semantics to ensure memory is zeroed? Also given javascript is garbage col

Was thinking the same thing. Like the CPU marked it's good to have competition with GPUs but it would be interesting if Nvidia picked up/ partnered with AMD. Oh well let's see how OpenPOWER pans out.

Not sure on that sadly, our users don't really mix compilers within a build. With regards to the Cray modules they do go out of their way to avoid you mixing compilers (in terms of setting conflicts in the module files). I'll ask

Cool, thanks for replying. Didn't know you guys were actually running anything on Daint (I'd heard tests were planned). Your earlier comment was the first time I'd heard of the ICON model too. Quite an informative day on HN.

Ha though so, it's a small world ;) The MeteoSwiss utilizes K80 GPU's in the system hosted at CSCS though right? Or were you saying you don't expect a shift to accelerator-based weather models as a general trend?

Well production runs on one of two identical machines. This kind of redundancy is not uncommon for weather sites. One of these will run the production version of the forecast and the other will be running version n+1. We flip between the tw

Not sure exactly what you're after here. The systems have assorted versions of Fortran compilers from both Cray and Intel. With regards to versions of the language standard used/ required for the models I'm not sure.
