The Last Itanium, At Long Last
In a world of survival of the fittest coupled with mutations, something always has to be the last of its kind. And so it is with the “Kittson” Itanium 9700 processors, which Intel quietly released earlier this month and which will mostly see action in the last of the Integrity line of midrange and high-end systems from Hewlett Packard Enterprise.
The Itanium line has a complex history, perhaps fitting for a computing architecture that was evolving from the 32-bit X86 architecture inside of Intel and that was taken in a much more experimental and bold direction when the aspiring server …

Some Surprises in the 2018 DoE Budget for Supercomputing
The US Department of Energy fiscal year 2018 budget request is in. While it reflects much of what we might expect in pre-approval format in terms of forthcoming supercomputers in particular, there are some elements that strike us as noteworthy.
In the just-released 2018 FY budget request from Advanced Scientific Computing Research (ASCR), page eight of the document states that “The Argonne Leadership Computing Facility will operate Mira (at 10 petaflops) and Theta (at 8.5 petaflops) for existing users, while turning focus to site preparations for deployment of an exascale system of novel architecture.”
Notice anything missing in this description? …

Network Slices
There has been a lot of chatter recently in the 5G wireless world about network slices. A draft was recently published in the IETF on network slices—draft-gdmb-netslices-intro-and-ps-02. But what, precisely, is a network slice?
Perhaps it is better to begin with a concept most network engineers already know (and love)—a virtual topology. A virtual topology is a set of links, with some subset of connected devices (either virtual or real), that act as a subset of the network. Isn’t such a subset of the network a “slice” if you look at it from a different angle? To ask the question in a different way: how are network slices different from virtual network overlays?
To begin, consider the control plane. In the world of virtual topologies, there is generally one control plane that provides reachability, as well as sorting reachability into each virtual topology. For instance, BGP carries a route target and a route discriminator to indicate which virtual topology any particular destination belongs to. A network slice, by contrast, actually has multiple control planes—one for each slice. There will still be one “supervisor control plane,” of course, much like there is a hypervisor that manages the resources of each Continue reading
