Peering Through Opaque HPC Benchmarks

If Xzibit worked in the HPC field, he might be heard to say “I heard you like computers, so we modeled a computer with your computer so you can simulate your simulations.”

But simulating the performance of HPC applications is more than just recursion for comedic effect, it provides a key mechanism for the study and prediction of application behavior under different scenarios. While actually running the code on the system will yield a measure of the wallclock time, it does little to provide an explanation of what factors impacted that wallclock time. And of course it requires the system …

Six Flags New England adds VR to another roller coaster

If riding a roller coaster with a virtual Superman isn’t your thing, Six Flags New England has an alternative pitch – get sent into space and fight alien invaders.The Agawam, Mass.-based amusement park today announced that its second coaster will get VR when it opens this spring. Partnering up with Samsung, the company said its Mind Eraser steel coaster will include the “Galactic Attack Virtual Reality Coaster” option, which will include a mixed reality feature that initially will let riders see the real world (including the rider next to them) in addition to the VR graphics. Like the Superman coaster, riders will put on a VR headset while enjoying the physical roller coaster’s drops and spins.To read this article in full or to leave a comment, please click here

Why is incident response automation and orchestration so hot?

I couldn’t attend the RSA Conference this year, but many cybersecurity professionals and my ESG colleagues told me that incident response (IR) automation and orchestration was one of the hottest topics in the halls of the Moscone Center—through the bar at the W hotel and even at the teahouse on the garden at Yerba Buena.   Was this rhetoric just industry hype? Nope. This buzz is driven by the demand side rather than suppliers. In truth, cybersecurity professionals need immediate IR help for several reasons:1. IR is dominated by manual processes. Let’s face it, IR tasks such as fetching data, tracking events or collaborating with colleagues depend upon the organizational, communications and technical skills of individuals within the security operations team. These manual processes ultimately get in the way of overall IR productivity.To read this article in full or to leave a comment, please click here

CBRS Alliance: Shared spectrum services “a near-term opportunity”

The CBRS Alliance, which promotes LTE services in the shared 3.5 GHz Citizens Broadband Radio Service band, is riding high after signing up all of the Big 4 U.S. carriers, plus Samsung, and then seeing a slew of CBRS activity at the recent Mobile World Congress event in Barcelona.Neville Meijers, VP of business development at Qualcomm Technologies and chairman of the board for the CBRS Alliance, says “there’s a lot of interest in the combination of unlicensed and shared spectrum” for a number of use cases being tested for public and private services.I caught up with Meijers shortly after MWC to get up to speed on the latest CBRS action.To read this article in full or to leave a comment, please click here

Cisco security advisory dump finds 20 warnings, 2 critical

It’s a bad week for all things network security as Cisco spewed out 20 Security Advisories and Alerts – two critical and three high-impact – that customers should be aware of and implement patches where they can.Cisco, like other big enterprise vendors, regularly issues security warnings but 20 in one day is an unusual amount for the networking giant. Others like Microsoft and Oracle issue tons of security bulletins monthly mostly without much fanfare – for example Microsoft for March, released 18 security bulletins split into nine critical and nine important security updates.To read this article in full or to leave a comment, please click here

Raspberry Pi roundup: Pi Day, Remembrances of Pis Past, competitor corner, STEM and SKULLS

Since we’ve just had a Raspberry Pi anniversary, you might think that it’s excessive to trumpet another Pi-related holiday just one week later, but, well, Tuesday was Pi Day, this is the internet, and I’m afraid that’s just the way these things go.OK, so Pi Day isn’t, strictly speaking, a Raspberry Pi thing – around these parts, it’s more of a pie-in-the-face thing – but that didn’t stop the Raspberry Pi community from getting in on the act. The estimable Alex Bate over at the official Raspberry Pi Foundation blog put together a graphic to make sure everyone understands certain key points of terminology.To read this article in full or to leave a comment, please click here

How Does Internet Work - We know what is networking

I know, this is not about networking but I received few great feedbacks to my posts about the matter so I decided to share with you the materials I used to write it. It’s not about networking, but it is about everything. QUANTA?! I was writing about quantum cryptography and quantum key distribution process few months ago (which are network related). When I started to write those articles I was not aware that it will take me more that two months to write something close to understandable about quantum world. As it came out, like many times before, I was in

IDG Contributor Network: What the AWS outage can teach us about WAN deployments

The outage that hit Amazon Web Services' Simple Storage Service earlier this month might have been unusual in its impact, but not in its cause—a configuration error. Service providers suffer outages for all sorts of reasons. Backhoes take out local access loops. Seismic events and fishing trawlers cut underwater cables. And, yes, humans make mistakes.RELATED: SD-WAN: What it is and why you will use it one day About three years ago, I was called in by a customer to help address a problem in their MPLS network. At the time, I ran MPLS Experts, a predecessor of SD-WAN Experts, and had developed a reputation for knowing a thing or two about global MPLS/VPLS services. The customer was noticing packets with unknown IPs on its carrier-managed private network. After we reviewed the logs, the cause became apparent: One of the carrier techs had misconfigured the VRF/VFI identifiers, accidentally connecting a different customer to their private network.  To read this article in full or to leave a comment, please click here

The FCC chief’s call to action could push 5G along faster

U.S. FCC Chairman Ajit Pai has pledged his agency will respond more quickly to new technology proposals, a move that might influence the direction of 5G development around the world.Pai was appointed by President Donald Trump in January. In his first major policy address on Wednesday, Pai directed Federal Communications Commission staff to follow a little-known section of U.S. communications law that says the agency should decide within a year whether a new technology or service is in the public interest."Going forward, if a petition or application is filed with the FCC proposing a new technology or service, we'll supply an answer within a year," Pai said in his speech at Carnegie-Mellon University in Pittsburgh.To read this article in full or to leave a comment, please click here
