Where Is MongoDB Taking Its Giant Ideas?
Q&A: At its annual conference, MongoDB delivered a new Database as a Service offering and a new Apache Spark Connector, but the company is far from done. With a theme of “Giant Ideas,” MongoDB is breaking new ground as a hot NoSQL database. This week at its MongoDB World conference, the company declared that its database enables developers to launch their giant ideas and create big things. As part of that, Mongo DB announced Atlas, its new database-as-a-service offering, as well as a new MongoDB Connector for Apache Spark. That connector enables developers and data scientists to gain insights from live, operational and streaming data. However, the company continues to gain momentum in the database world and is growing and picking up new customers—many of which have come from traditional SQL databases like Oracle and Microsoft’s SQL Server. Many of its user organizations are .NET shops. “The whole raison d’etre of MongoDB is to unleash developer productivity,” Dev Ittycheria, MongoDB’s president and CEO, said during his keynote at the show…

This new model for quantum circuits is like a 5-decker sandwich

One of the challenges to realizing the benefits of quantum computing is finding a way to compactly assemble and then precisely control enough quantum bits, or “qubits,” to deliver on the technology’s enormous processing potential. Researchers at Penn State University said they’ve made a big advance.

Oracle pledges ‘x86 economics’ with new Sparc servers
The new processor is called the S7, a less powerful version of Oracle’s high-end M7 chip launched in October. Oracle sketched out plans for the chip last year under the code name Sonoma, and it launched the first products on Wednesday at OpenWorld in Brazil. The S7 is based on the same fourth-generation Sparc core as the M7, and it’s manufactured on the same 20-nanometer process. But there are eight cores per chip on the S7, compared with 32 on the M7. Like the M7, the new chip has “software in silicon” features for accelerating database and security functions. But it also integrates memory and I/O interfaces that for the M7 are separate on the motherboard, helping to keep costs down. There’s just one version offered, at 4.27GHz. Oracle announced two standalone servers with the new chip, the S7-2 and S7-2L, as well as an engineered system, the MiniCluster S7-2, which is a smaller version of the Oracle SuperCluster. The S7-2 is a 1 rack-unit server, designed for maximum density, sold with one or two processors. The S72L is a 2 rack-unit system, with two processors, that handles more storage configurations. Both can use a mix of SAS and NVMe storage. The servers start just north of $11,000 with a single processor, 64GB of memory and two 600GB disk drives, and run to about $50,000 with two processors and a terabyte of memory…

[ Desde el Microprocessor Report ] IBM TrueNorth Tackles Deep Learning
IBM’s TrueNorth is a Darpa-funded experimental ASIC that directly implements a simple model of the brain. It tremendously improves power efficiency by eliminating the traditional memory model and by relying on fixed-function computation. The device is fabricated in Samsung’s 28nm LPP process and is highly energy efficient, dissipating a mere 73mW while classifying 300×200-pixel video data.
By David Kanter
TrueNorth is a wholesale departure from modern computer architecture. Computations are fixed and embedded in a hardware “neuron” or core instead of a stored program; the chip is programmed by configuring the connections among neurons. When a neuron accumulates enough input activity, it will fire, potentially cascading to other neurons throughout the chip. Each core needs just a few kilobytes of on-chip SRAM to hold state instead of the gigabytes that programmers use in conventional computers.
Programs for TrueNorth must map well to this model. Many neural networks are a natural fit, although the unusual chip design imposes limits on network size and complexity. IBM has demonstrated that applications such as visual object classification work well, and even some convolutional neural networks can be expressed in this fashion. The company and academic researchers are currently investigating what other tasks can take advantage of the TrueNorth architecture.
In exchange for giving up general-purpose programmability, TrueNorth is very energy efficient. Although IBM lacks benchmark comparisons against efficient CPU implementations for the few applications that run on TrueNorth, we believe the energy-efficiency gains could be three to four orders of magnitude — an impressive feat, even though the design is a research vehicle rather than a commercial product. A commercial implementation that draws on IBM’s techniques would assuredly sacrifice some efficiency for programmability. Even so, a real product might achieve a 100x gain, which is well beyond the 10x gains promised by current deep-learning processors.

[ Desde el Microprocessor Report ] 14nm Broadwell-EX Boosts Brickland
Intel’s 14nm Broadwell-EX is the third socket-compatible processor in the Brickland Xeon E7 platform. Compared with its predecessor (Haswell-EX), it boosts performance thanks to extra cores and a more advanced north bridge. The new server processor doubles the memory capacity to 3TB per socket and also adds security and virtualization features.
By David Kanter
Intel used the 14nm technology to increase the Broadwell-EX core count by 33% while still reducing the die size. Broadwell-EX and the HCC variant of Broadwell-EP share the same 456mm^2 silicon integrating 24 cores. The EP products (e.g., Xeon E5-2600v4 series) disable two of the cores, increasing yield. The EX models are equipped with three QPI links and 32 PCIe 3.0 lanes. They also have four SMI2 memory interfaces to discrete memory buffers, which in turn fan out to a total of 24 DIMMs.
Broadwell-EX carries forward many north-bridge and power-management innovations that debuted in the first Xeon D and the Xeon E5-2600v4 (Broadwell-EP) line. These features include more-advanced dynamic voltage and frequency scaling (e.g., separate curves for AVX and non-AVX code) and Resource Director Technology to manage contention in the cache and memory controllers. The cluster-on-die (CoD) coherence mode partitions the processor into two clusters, each containing a memory controller as well as half the cores and L3 cache.
The Broadwell-EX (and EP) memory interfaces handle 3D-stacked (3DS) DIMMs. These DIMMs enable designers to increase the DRAM count while keeping constant the electrical load on the bus. In particular, 3DS DIMMs are available in 128GB capacity, allowing a single Xeon E7v4 to connect to 3TB of memory — double the previous generation.
Overall, the Xeon E7v4 family boosts performance by 15-30% on enterprise workloads compared with the previous-generation Xeon E7v3 family, depending on the model. This gain comes without increasing power over the previous generation.

Scientists observe first signs of healing in the Antarctic ozone layer
Scientists at MIT and elsewhere have identified the “first fingerprints of healing” of the Antarctic ozone layer, published today in the journal Science. The team found that the September ozone hole has shrunk by more than 4 million square kilometers—about half the area of the contiguous United States—since 2000, when ozone depletion was at its peak. The team also showed for the first time that this recovery has slowed somewhat at times, due to the effects of volcanic eruptions from year to year. Overall, however, the ozone hole appears to be on a healing path…

DockerCon Showcases New Docker Release, Containers-as-a-Service Model
Docker is one of the most hyped technologies in IT today, as containers have gone mainstream. At the DockerCon 16 event, which was held June 19-21 at the Washington State Convention Center in Seattle, 4,000 people gathered to learn and talk about Docker. Among the news coming out of the event was the release of Docker 1.12, which includes an integrated container orchestration capability referred to as Swarm mode. Docker CEO Ben Golub, meanwhile, said IaaS and PaaS either deliver too little or too much of what an organization needs, so he sees the emerging containers-as-a-service (CaaS) space growing, which is where Docker is aiming to play with its Docker Datacenter technology. Golub also announced a public beta of the Docker Store, which is a curated set of containerized applications that users can obtain. Also debuting was the public beta release of the Docker native application for Windows and Mac, opening up those products from the private beta that was first announced in March. Other public betas announced at DockerCon were Docker for Azure and Docker for AWS public clouds. The general idea with the new public beta releases is to provide more seamless, integrated experiences for users of specific platforms when using Docker. In a keynote at the conference, Docker founder Solomon Hykes claimed most people don’t care about containers; they actually just really care about applications…
