Parallel Programming Approaches for Accelerated Systems Compared

In high performance computing, machine learning, and a growing set of other application areas, accelerated, heterogeneous systems are becoming the norm.

With that state come several parallel programming approaches; from OpenMP, OpenACC, OpenCL, CUDA, and others. The trick is choosing the right framework for maximum performance and efficiency—but also productivity.

There have been several studies comparing relative performance between the various frameworks over the last several years, but many take two head to head for compares on a single benchmark or application. A team from Linneaus University in Sweden took these comparisons a step further by developing a custom tool …

IDG Contributor Network: The big news at DockerCon 2017 was no big news

The biggest news from DockerCon 2017, the semi-annual conference on Linux containerization, was the lack of big news. After the last two years of feverish development, there are signs one of the hottest trends in tech might be slowing down.“I’m not sure,” said one software developer loitering just outside of the Austin Convention Center. That was the most common response to my question, “What was the biggest news at DockerCon this year?” I must have asked 30 people that question over my two days at the event. An informal, unscientific polling of my Twitter, LinkedIn and Facebook connections has been similar.To read this article in full or to leave a comment, please click here

More Windows PCs infected with NSA backdoor DoublePulsar

The number of Windows computers infected with NSA backdoor malware continues to rise since Shadow Brokers leaked the hacking tools on April 14.DoublePulsar infection rate climbing Two different sets of researchers scanning for the DoublePulsar implant saw a significant bump in the number of infected Windows PCs over the weekend.For example, Dan Tentler, CEO of the Phobos Group, suggested that Monday would not be a good day for many people, as his newest scan showed about 25 percent of all vulnerable and publicly exposed SMB machines are infected.To read this article in full or to leave a comment, please click here

Bring Your Own Authentication is upending online security practices

This vendor-written tech primer has been edited by Network World to eliminate product promotion, but readers should note it will likely favor the submitter’s approach.Seeing the success of the Bring Your Own Device movement, a cadre of leading companies are starting to explore if a similar approach can be used to address the authentication challenge. If BYOD essentially makes the device a proxy for the work environment, can that same device serve as a proxy for customers online?This new movement, known as Bring Your Own Authentication (BYOA), holds the same promise of reimagining the way we think of authentication, putting the consumer (and device) front and center in the interaction, and relegating passwords to the background or eliminating them completely. But there are challenges to overcome in order for mass adoption.To read this article in full or to leave a comment, please click here

Windows laptops running on ARM chips is a terrible idea

Last week, Qualcomm revealed that the first Windows 10 laptops using its Snapdragon 835 processors are due to hit the market late in 2017. That’s a big deal because up until now, Windows 10 has run only on x86 chips from Intel and AMD, and the Snapdragon chips use an ARM-based architecture optimized for mobile use.Windows 10 on ARM: Thinner, lighter, more connected Here’s how PC World described these new machines, which are being jointly developed by Microsoft and Qualcomm:To read this article in full or to leave a comment, please click here

Ubuntu Phone security updates end in June, app store closing

When Mark Shuttleworth, founder of Canonical (the company behind the Ubuntu Linux distribution), announced his company would not only be abandoning their custom desktop environment (Unity), but also halting development on their phone/tablet operating system, many questions were left unanswered.One of those questions: What happens to the existing phones and tablets running Ubuntu Touch that have already been sold? To read this article in full or to leave a comment, please click here

Russian man receives longest-ever prison sentence in the US for hacking

A 32-year-old Russian hacker was sentenced to 27 years in prison in the U.S. for stealing millions of payment card details from businesses by infecting their point-of-sale systems with malware.The sentence is the longest ever handed out in the U.S. for computer crimes, surpassing the 20-year jail term imposed on American hacker and former U.S. Secret Service informant Albert Gonzalez in 2010 for similar credit card theft activities.Roman Valeryevich Seleznev, a Russian citizen from Vladivostok, was sentenced Friday in the Western District of Washington after he was found guilty in August of 10 counts of wire fraud, eight counts of intentional damage to a protected computer, nine counts of obtaining information from a protected computer, nine counts of possession of 15 or more unauthorized access devices and two counts of aggravated identity theft.To read this article in full or to leave a comment, please click here

8 ways the iPhone 8 can beat the Galaxy S8

If there wasn’t already a mountain of pressure on Apple to deliver something spectacular with this year’s iPhone update, there surely is now. If you haven’t noticed, Samsung has released the Galaxy S8 and S8+, and they’re pretty remarkable. As a former iPhone 7 Plus user, the S8+ might very well be the best phone I’ve ever used, with a stunning screen, speedy processor, and, yes, a gorgeous design.But what makes the S8 so amazing is how unique it is. I got to spend a week with it while writing my review, and I came away stunned. For the first time in a while, Samsung is standing alone on the cutting edge with a phone that needs to be seen to be believed. From its barely there bezels to its brilliant wraparound screen, the Galaxy S8 truly gives Apple a run for its money. No joke, it actually makes the iPhone 7 look pretty stale.To read this article in full or to leave a comment, please click here

Oracle floats Java hardware acceleration proposal

A proposal currently floating in the Java community would use hardware acceleration to improve bulk calculations in the platform.Project Trinity would explore enhancing execution of bulk aggregate calculations over Streams by offloading calculations to hardware accelerators. Streams in Java allow developers to express calculations so that data parallelism can be efficiently exploited, and the Stream capability in Java Standard Edition 8 is for processing data declaratively while leveraging multicore architectures.[ The big 4 Java IDEs reviewed: See how Eclipse, NetBeans, JDeveloper, and IntelliJ IDEA stack up. | Keep up with hot topics in programming with InfoWorld's App Dev Report newsletter. ] "Such calculations are prime candidates for leveraging enhanced data-oriented instructions on CPUs, such as SIMD instructions or offloading to hardware accelerators, such as the SPARC Data Accelerator co-processor," said Karthik Ganesan, from Oracle's performance and applications engineering group, in his proposal made Friday in an email-based OpenJDK discussion forum.To read this article in full or to leave a comment, please click here
