Close to a year ago when more information was becoming available about the Knights Landing processor, Intel released projections for its relative performance against two-socket Haswell machines. As one might image, the performance improvements were impressive, but now that there are systems on the ground that can be optimized and benchmarked, we are finally getting a more boots-on-the-ground view into the performance bump.
As it turns out, optimization and benchmarking on the “Cori” supercomputer at NERSC are showing that those figures were right on target. In a conversation with one of the co-authors of a new report highlighting the optimization …
Optimization Tests Confirm Knights Landing Performance Projections was written by Nicole Hemsoth at The Next Platform.
This week, I want to do a little more housekeeping before we get into actually asking questions of the bgp code. First there is the little matter of an editor. I use two different editors most of the time, Notepad++ and Atom.
I haven’t actually chosen one or the other—I tend to use both pretty interchangeably, so you’re likely to see screen shots from Continue reading
Predix on Azure will be available in Q2 2017.

The life of a request to CloudFlare begins and ends at the edge. But the afterlife! Like Catullus to Bithynia, the log generated by an HTTP request or a DNS query has much, much further to go.
This post comes from CloudFlare's Data Team. It reports the state of processing these sort of edge logs, including what's worked well for us and what remains a challenge in the time since our last post from April 2015.
In an edge network, where HTTP and DNS clients connect to thousands of servers distributed across the world, the key is to distribute those servers across many carefully picked points of presence—and with over 80 PoPs, no network has better representation than CloudFlare. The reverse, however, has to happen for that network's logs. After anycast has scattered requests (and queries) to thousands of nodes at the edge, it's the Data Team's job to gather the resulting logs to a small number of central points and consolidate them for easy use by our customers.
The charts above depict (with some artifacts due to counter resets) the total structured logs sent from the edge to one Continue reading
This is just to delicious a parallel to pass up.
Here we have Google building a new four story datacenter Scaling Up: Google Building Four-Story Data Centers:
And here we have a new vertical farm from AeroFarms:
Both have racks of consumables. One is a rack of bits, the other is a rack of bites. Both used to sprawl horizontally across huge swaths of land and now are building up. Both designs are driven by economic efficiency, extracting the most value per square foot. Both are expanding to meet increased demand. It's a strange sort of convergence.
