Disruptive Technologies on the Post Exascale Horizon

Although the timeline for reaching exascale class computing continues to stretch farther into the future, research teams are keeping an eye on what technologies will shape the machines of the post-exascale timeframe, which is in the 2022-2030 timeframe.

While many of the technologies stated in a comprehensive report about post-exascale supercomputers are already in process, albeit in various stages of development and adoption, there is little consensus about which mode of computing will lead us into an era of unprecedented data and simulation potential. Still, the effort on behalf of the EuroLab-4-HPC program is notable in its divisions between where …

SkyGiraffe’s Tableau connector aims to ease business data visualization

While business intelligence software like Tableau helps companies better understand the data that they have saved up in systems of record like databases and CRM software, it can be hard to get the entire picture of a business from the plethora of different sources available.SkyGiraffe is launching a new connector Tuesday to help with that by allowing companies to take live data from a diverse set of systems of record and visualize it in Tableau. The connector is supposed to give businesses a single consistent means of visualizing data, without having to repeatedly configure a bunch of different integrations.To read this article in full or to leave a comment, please click here

BrandPost: Network Performance On Demand

Organizations today need speed and reliability, but also want flexibility and freedom to adjust their services levels and costs to meet changing needs. As health care providers shift to electronic records and files, they’re finding the need to scale up network performance but in a cost-conscious environment are wary about locking themselves into expensive options they need only for high-peak periods.For the Austin Cancer Center, huge imaging files can be a vital component of diagnosis and treatment. But moving large data sets such as digital PET scan images of a gigabyte or more between the 12 campuses in the system would create a huge bottleneck over most enterprise Ethernet LANs, or a huge expense to create peak capacity that is often underutilized.To read this article in full or to leave a comment, please click here

Ganging up Accelerators to Beat Scale Limits

It is not news that offloading work from CPUs to GPUs can grant radical speedups, but what can come as a surprise is that scaling of these workloads doesn’t change just because they run faster. Moving beyond a single node means encountering a performance wall, that is, unless something can glue everything together so it can scale at will.

There are already technologies that can take multiple units of compute and have them share work from supercomputing and other areas (consider ScaleMP, for instance) but there are limitations to these approaches and thus far, they haven’t extended to meet the …

Samsung Note7: A phenomenal phablet flame-out timeline

The Samsung Galaxy Note7 smartphone's demise has been swift: Introduced in early August, the phablet is now off the market due to it being a fire hazard. Early reviews of the Samsung Galaxy Note7 phablet were generally positive. Headlines described the latest Apple iPhone 7 rival as a "Pricey phablet made for power users" and "an excellent phone for the high-price market." But batteries that burn too hot and burst into flames have resulted in much less glowing headlines and a full-fledged business disaster for Samsung, which has now issued a recall of both the original and replacement Note7 phones. To read this article in full or to leave a comment, please click here

Igneous Melds ARM Chips And Disks For Private S3 Storage

The only companies that want – and expect – all compute and storage to move to the public cloud are those public clouds that do not have a compelling private cloud story to tell. But the fact remains that for many enterprises, their most sensitive data and workloads cannot – and will not – move to the public cloud.

This almost demands, as we have discussed before, the creation of private versions of public cloud infrastructure, which interestingly enough, is not as easy as it might seem. Scaling infrastructure down so it is still cost effective and usable by …

Worth Reading: Elliptic Curve Cryptography and DNS

Erasthosthenes of Cyrene was an ancient Greek of some astounding learning, becoming the Chief Librarian at that fabled wonder of the ancient world, the library of Alexandria, in the third century BCE. Not only has he been credited as the first person to calculate the circumference of the earth, but for the purposes of this article his claim for posterity is based on his work in number theory, and in particular his invention of the Sieve of Erastosthenes as a means of identifying prime numbers. His method is complete and accurate, but for very large numbers the process is inordinately slow. And we haven’t really made it much faster in the intervening 2,200 years. The related problem, that of computing the prime number factors of a very large integer also takes a long time as at its heart is a basic enumeration problem that grows as the size of the number grows. —Potaroo

Samsung officially announces the Galaxy Note 7 and a refreshed GearVR

Samsung’s next phone-tablet hybrid device has officially landed. The company introduced the sixth-generation Galaxy Note 7 phablet in New York City on Tuesday. It features the latest hardware, a pressure sensitive stylus, and a spruced up interface, all packaged into a shiny metal-and-glass, water-resistant shell. And for the virtual reality-obsessed, Samsung has announced a new GearVR headset designed just for the Galaxy Note 7.  Meet the new phablet  You might be wondering why there’s no Galaxy Note 6 this year. That’s because Samsung opted to skip that number and jump straight to the number 7 so that its phablet line and flagship family—the Galaxy S7 and Galaxy S7 Edge—are directly aligned. Frankly, it makes sense to have both device types on the same page, so to speak. To read this article in full or to leave a comment, please click here

Microsoft released 10 patches: 5 rated critical, 5 fixed zero-day flaws

It is the first month for Microsoft’s new patching model. Older Windows OSes will be treated like Windows 10, with the patches all rolled into a big bundle meant to fix security and non-security issues. However, there will also be a monthly security update that is supposed to resolve that month’s issues without the previous month's fixes as well. On the third Tuesday of the month, the week after Patch Tuesday, Microsoft will release a preview of the upcoming patches so the non-security fixes can be tested to make sure the big rolled-up patch doesn’t blow anything up on some systems.To read this article in full or to leave a comment, please click here
