I’ve recently been thinking a lot about application-specific workloads and architectures (Optimize Scalalable Workload-Specific Infrastructure for Customer Experiences), and it got me to thinking about the extremes of the server spectrum – the very small and the very large as they apply to x86 servers. The range, and the variation in intended workloads is pretty spectacular as we diverge from the mean, which for the enterprise means a 2-socket Xeon server, usually in 1U or 2U form factors.
At the bottom, we find really tiny embedded servers, some with very non-traditional packaging. My favorite is probably the technology from Arnouse digital technology, a small boutique that produces computers primarily for military and industrial ruggedized environments.
Slightly bigger than a credit card, their BioDigital server is a rugged embedded server with up to 8 GB of RAM and 128 GB SSD and a very low power footprint. Based on an Atom-class CPU, thus is clearly not the choice for most workloads, but it is an exemplar of what happens when the workload is in a hostile environment and the computer maybe needs to be part of a man-carried or vehicle-mounted portable tactical or field system. While its creators are testing the waters for acceptance as a compute cluster with up to 4000 of them mounted in a standard rack, it’s likely that these will remain a niche product for applications requiring the intersection of small size, extreme ruggedness and complete x86 compatibility, which includes a wide range of applications from military to portable desktop modules.
The Politburo is making a comeback
Winston Churchill described Soviet-era politics as a riddle, wrapped in a mystery, inside an enigma. It came to mind recently as I was engaged in a conversation with an I&O professional who works for a US-based company, and he needed help. Seems his executives had decided that due to two data breaches over the past year from stolen hard drives, that the new Central Committee policy should be to have everyone use a locked down virtual desktop, no matter their role or workstyle. It was hard for me to conjure up a picture of the profound lack of understanding that led to such a misguided policy, though images of nondescript buildings, row after row of undifferentiated cubicles, and Gulag-style productivity quotas came quickly to mind. Had he not been on the other end of a telephone line, he could've knocked me over with a feather.
Big vendors are using top party relationships to push huge pork-barrel deals under the banner of security and mobility
Intel has been publishing research for about a decade on what they call “3D Trigate” transistors, which held out the hope for both improved performance as well as power efficiency. Today Intel revealed details of its commercialization of this research in its upcoming 22 nm process as well as demonstrating actual systems based on 22 nm CPU parts.
The new products, under the internal name of “Ivy Bridge”, are the process shrink of the recently announced Sandy Bridge architecture in the next “Tock” cycle of the famous Intel “Tick-Tock” design methodology, where the “Tick” is a new optimized architecture and the “Tock” is the shrinking of this architecture onto then next generation semiconductor process.
What makes these Trigate transistors so innovative is the fact that they change the fundamental geometry of the semiconductors from a basically flat “planar” design to one with more vertical structure, earning them the description of “3D”. For users the concepts are simpler to understand – this new transistor design, which will become the standard across all of Intel’s products moving forward, delivers some fundamental benefits to CPUs implemented with them:
Leakage current is reduced to near zero, resulting in very efficient operation for system in an idle state.
Power consumption at equivalent performance is reduced by approximately 50% from Sandy Bridge’s already improved results with its 32 nm process.
One evening in 1972 I was hanging out in the computer science department at UC Berkeley with a couple of equally socially backward friends waiting for our batch programs to run, and to kill some time we dropped in on a nearby physics lab that was analyzing photographs of particle tracks from one of the various accelerators that littered the Lawrence Radiation Laboratory. Analyzing these tracks was real scut work – the overworked grad student had to measure angles between tracks, length of tracks, and apply a number of calculations to them to determine if they were of interest. To our surprise, this lab had something we had never seen before – a computer-assisted screening device that scanned the photos and in a matter of seconds determined it had any formations that were of interest. It had a big light table, a fancy scanner, whirring arms and levers and gears, and off in the corner, the computer, “a PDP from Digital Equipment.” It was a 19” rack mount box with an impressive array of lights and switches on the front. As a programmer of the immense 1 MFLOP CDC 6400 in the Rad Lab computer center, I was properly dismissive…
This was a snapshot of the dawn of the personal computer era, almost a decade before IBM Introduced the PC and blew it wide open. The PDP (Programmable Data Processor) systems from MIT Professor Ken Olsen were the beginning of the fundamental change in the relationship between man and computer, putting a person in the computing loop instead of keeping them standing outside the temple.
