HPE refreshes its Superdome servers with SGI technology



Can two old technologies make it in the brave new world of cloud computing? Hewlett-Packard Enterprise (HPE) thinks yes with its updates to the Superdome servers featuring its recently acquired SGI technology.

HPE bought SGI in late 2016, ending for good the name and company that was once a Hollywood darling. The company enjoyed almost celebrity status around 1993 when its computers were credited for creating the realistic dinosaurs in the movie Jurassic Park.


After that, though, it fell on hard times as the environment zigged and poor management zagged, blowing one opportunity after another. In 2009, Rackable Systems acquired SGI’s assets and changed its name to SGI because it thought there was some value in the name — for some inexplicable reason.

IDG Contributor Network: How blockchain technology could affect the future of network engineering



Blockchain, also referred to as distributed ledger, is the concept behind the success of Bitcoin and provides a dynamic digital register of transactions. Think of it as a database that’s distributed throughout a network. Information is continually shared and reconciled throughout multiple nodes and each one has an identical copy of the database. Transactions within this database are audited and agreed upon by consensus. This decentralized method of keeping track of changes ensures the ledger can’t be practically controlled by any one entity, eliminates the possibility of single-points of failure, and allows for the verification of transactions without the need for third-party intervention. Since each interaction is public, blockchain technology offers a reliable, incorruptible transaction-based infrastructure and the value it provides isn’t just limited to cryptocurrency.

Qualcomm ships ARM chip to challenge Intel in cloud data centers






Qualcomm's much-anticipated ARM-based Centriq 2400 product line, which started shipping commercially this week, is a worthy contender to break Intel's virtual monopoly in the server processor arena, where data center operators are thirsting to see competition to help bring down costs.

An unsolicited acquisition bid for Qualcomm from Broadcom, emerging server-chip competitors and legal wrangles involving Apple and other vendors, however, cast a bit of a shadow on prospects for the new chip.

Qualcomm revealed some impressive specs at an industry event in San Diego Wednesday, bringing out a a variety of big-time cloud, hardware and software providers to show support.

IDG Contributor Network: Thoughts & prayers don’t stop mass shooters. Technology might.



It’s heartbreaking. Gun violence kills 93 Americans every day while politicians send their thoughts and prayers. 2017 has seen two of the deadliest mass shootings in American history.

How can technology help reduce mass shootings? How can shooters be authenticated before they can fire? How can the police be alerted when a large number of firearms are present at an unusual location? Can an excessive number of shots fired be prevented?

Background


Americans make up about 4.4 percent of the global population but own 42 percent of the world’s guns. And approximately one in three gunmen is American according to a study by Adam Lankford, a professor at the University of Alabama. Firearms are an $11 billion per year industry with over 300 million existing guns in circulation. About 40% of Americans say they own a gun or live in a household with one. A recent survey reports that the US has the highest rate of murder by firearms in the developed world. Mass shootings cost Americans over $229 billion per year.

The cream of the Top500 supercomputer list in November 2017, these 10 supercomputers are used for modeling the weather, weapons, ocean currents and other physical phenomena. They not only outperform every other machine on the planet, they also demonstrate the technologies your business might use, at a smaller scale, to get the best performance in the least space or using the least energy.

Supercomputing is becoming super-efficient, Top500 list shows



Supercomputing is becoming super-efficient. The highest climber in the latest Top500 list of the world's fastest supercomputers is also one of the highest scorers on the Green500 ranking of the world's most efficient.

But the November 2017 edition of the Top500 and Green500 is also remarkable in other ways, as it marks a tipping point in U.S. dominance of the list.

[ See these top supercomputers at our slideshow 10 of the world’s fastest supercomputers. ]

Chinese systems now outnumber U.S. systems on the list by 202 to 144, a reversal of the situation just six months ago, when the U.S. had 169 systems in the Top500 vs China's 160. It will still be a long while before third-placed Japan overtakes the U.S.: It has 35 systems in the list, followed by Germany with 20, France with 18, and the UK with 15.

5 tricks for using the sudo command



The sudoers file can provide detailed control over user privileges, but with very little effort, you can still get a lot of benefit from sudo. In this post, we're going to look at some simple ways to get a lot of value out of the sudo command in Linux.

Trick 1: Nearly effortless sudo usage


The default file on most Linux distributions makes it very simple to give select users the ability to run commands as root. In fact, you don’t even have to edit the /etc/sudoers file in any way to get started. Instead, you just add the users to the sudo or admin group on the system and you’re done.

Adding users to the sudo or admin group in the /etc/group file gives them permission to run commands using sudo.

Manage user performance, not the network, with machine learning-based tools



Over the past decade, network management tools have evolved from being fault based to performance based. This has become a critical element in running infrastructure because faults don’t matter as much.

That might seem like a strange thing to say, but consider the fact that critical infrastructure such as switches, routers, Wi-Fi access points and servers are deployed in a way to protect against outages. Infrastructure is built so redundantly today that any hardware device can go down and its likely no one will notice.


A bigger problem is managing user performance. Often users call in about a certain application not working well, but when the engineer looks at the dashboard, everything is green. Performance problems are much harder to diagnose and can kill employee productivity.

IDG Contributor Network: The benefits of multi-cloud computing



Its application might be a tough concept to grasp, but the idea of multi-cloud computing is a simple one. It’s the choice of a business to distribute its assets, redundancies, software, applications and anything it deems worthy not on one cloud-hosting environment, but rather across several. 

At its surface, this concept might seem to be rubbing against the grain a bit. For security purposes alone, having all your company’s proverbial eggs in one basket appears the best way to keep your information from suffering leakage. Plus, many cloud-hosting companies will offer perks and discounts when your company use their services in totality.   

However, the model of using multiple cloud services to house your business’s functions and features has an impressive list of advantages that can provide security, flexibility, cost-effectiveness and more to increase your business’s efficiency and ensure it stays up and running 24 hours a day.

AMD charges back into the HPC fray with new systems



After years of watching its presence shrink on the Top 500 supercomputer list, AMD is battling back with a new set of EPYC-based server processors and specially-tuned GPUs for high-performance computing (HPC) in a complete server system.

The company and its partners announced new servers with the EPYC 7601 processor, which it claims is three times more performance-efficient than Intel’s best Xeon server processors, the Xeon Platinum 8180M1, as measured by SPECfp[i] benchmark. The news came at the Supercomputing ’17 show taking place in Denver.

Target workloads for AMD solutions include machine learning, weather modeling, computational fluid dynamics, simulation and crash analysis in aviation and automotive manufacturing, and oil and gas exploration, according to the company.
