A First Look at Summit Supercomputer Application Performance

Big iron aficionados packed the room when ORNL’s Jack Wells gave the latest update on the upcoming 207 petaflop Summit supercomputer at the GPU Technology Conference (GTC18) this week.

In just eight years, the folks at Oak Ridge have pushed the high performance bar from the 18.5 teraflop Phoenix system to the 27 petaflop Titan. That’s a 1000x + improvement in eight years.

Summit will deliver 5-10x more performance than the existing Titan machine, but what is noteworthy is how Summit will do this. The system is set to have far fewer nodes (18,688 for Titan vs. ~4,800 for Summit) …

Let’s Encrypt Offers Free Multi-Domain HTTPS Certificates

Let’s Encrypt, a nonprofit certificate authority launched in 2016, has delivered on its pledge to offer free certificates that enable secure HTTP connections for complete domains.

The organization’s new wildcard certificate service, allowing website operators to secure all subdomains of a domain with a single certificate, should help the Internet become more secure by enabling wider deployment of HTTPS, Josh Aas, executive director of the Internet Security Research Group, wrote in a blog post. (Full disclosure: the Internet Society is a major sponsor of Let’s Encrypt.)

Last July, Let’s Encrypt had promised that it would offer free wildcard certificates. With the recent release of the ACMEv2 [Automatic Certificate Management Environment] Protocol, the organization delivered on that promise.

“Wildcard certificates can make certificate management easier in some cases, and we want to address those cases in order to help get the Web to 100% HTTPS,” Aas wrote. “We’re excited about the prospect of a 100% HTTPS Web and we’re working hard to get there.”

A wildcard certificate isn’t recommended for all websites, Aas noted. In most cases, other certificates, such as single-domain ones, will be more appropriate.

Although wildcard certificates enable streamlined management of HTTPS, some security Continue reading

Au revoir

Today I’m announcing my departure from Docker, the company I helped create ten years ago and have been building ever since. A founder’s departure is usually seen as a dramatic event. Sadly, I must report that reality is far less exciting in this case. I’ve had many roles at Docker over the years, and today I have a new, final one – as an active board member, a major shareholder and, I expect, a high maintenance Docker user. But I will no longer be part of day-to-day operations. Instead, after obsessing for so many years over my own ideas, I am rediscovering the joys of putting myself at the service of others – my friends, my family, and the brilliant entrepreneurs I’ve been lucky enough to advise and invest in over the years. Over the coming months I plan to use my experience to help them in any way I can.

This transition is simply another chapter in a long story of change, growth, hard work… and a lot of luck.

Ten years ago, I quit my job, returned to live with my mother in Paris and, together with my friends Kamel Founadi and Sebastien Pahl, started a company called Continue reading

People are really worried about IoT data privacy and security—and they should be

A new study from the Economist Intelligence Unit (EIU) shows that consumers around the world are deeply worried about in how their personal information is collected and shared by the Internet of Things (IoT). But let’s be honest, the problem isn’t that unsophisticated consumers are panicking for no reason. In fact, consumers are merely picking up on the very real inherent risks and uncertainties surrounding IoT data.Businesses are also worried about IoT security I’ll get into the results and implications of the survey in a moment, but first I want to note that business and professionals are equally concerned. Perhaps that’s why Gartner just predicted that IoT security spending will hit $1.5 billion by the end of the year, up 28 percent from 2017, and more than double to $3.1 billion by 2021.To read this article in full, please click here

How Edge Computing Compares with Cloud Computing

How Edge Computing Compares with Cloud Computing

What is the Open Compute Project?

The Open Compute Project began in 2011 when Facebook published the designs of some homebrew servers it had built to make its data centers run more efficiently.Facebook hoped that other companies would adopt and adapt its initial designs, pushing down costs and improving quality – and they have: Sales of hardware built to Open Compute Project designs topped $1.2 billion in 2017, double the previous year, and are expected to reach $6 billion by 2021.[ Don’t miss customer reviews of top remote access tools and see the most powerful internet of things companies . | Get weekly insights by signing up for our CIO Leader newsletter. ] Those figures, from IHS Markit, exclude hardware spending by OCP board members Facebook, Intel, Rackspace, Microsoft and Goldman Sachs, which all use OCP to some degree. The spend is still a small part of the overall market for data-center systems, which Gartner estimated was worth $178 billion in 2017, but IHS expects OCP’s part to grow 59 percent annually, while Gartner forecasts that the overall market will stagnate, at least through 2019.To read this article in full, please click here
