IO-500 Goes Where No HPC Storage Metric Has Gone Before

The landscape of HPC storage performance measurement is littered with unrealistic expectations. While there are seemingly endless strings of benchmarks aimed at providing balanced metrics, these far too often come from the vendors themselves.

What is needed is an independent set of measurements for supercomputing storage environments that takes into account all of the many nuances of HPC (versus enterprise) setups. Of course, building such a benchmark suite is no simple task—and ranking the results is not an easy exercise either because there are a great many dependencies; differences between individual machines, networks, memory and I/O tricks in software, and …

Oak Ridge Lab’s Quantum Simulator Pulls HPC Future Closer

Oak Ridge National Laboratory has been investing heavily in quantum computing across the board. From testing new devices, programming models, and figuring out workflows that combine classical bits with qubits, this is where the DoE quantum investment seems to be centered.

Teams at Oak Ridge have access to the range of available quantum hardware devices—something that is now possible without having to own the difficult-to-manage quantum computer on sight. IBM’s Q processor is available through a web interface, as is D-Wave’s technology, which means researchers at ORNL can test their quantum applications on actual hardware. As we just …

How to gauge your network’s openness

So, you’ve done your research, learned about the many benefits of open networking, and decided you’re interested in building an open network. Congratulations, and welcome to the future of networking! You’ve made a great first step, but maybe you’re concerned about where to begin when it comes to vendors. A lot of network providers will claim that they have open solutions…but how can you be sure you’re choosing the best one? Or how can you determine if your vendor is truly an open solution? Fortunately, there are ways to gauge if your solution is as open as you need it to be. If you don’t want to get duped by phony open vendors, make sure to keep these three things in mind:

The definition of “open networking” is not set in stone

While there are common criteria and ideologies that tend to be associated with open networks, the definition of open networking is still very fluid and can mean different things to different vendors. So, when you’re trying to decide which vendor to go with, don’t let them off easy with simple answers. Ask specific questions about what exactly “open” means to them. Simplicity, flexibility, and modularity are Continue reading

Security with Fish: My First Couple Months

In late June I wrote Security Here I Come!  The transition wasn’t quite as fast as I thought it would be.     But for the past couple months I’ve been able to really start digging in.

My initial response after watching just 2 CiscoLive VoDs?  FEAR!

• Defense Against Emerging Threats – BRKSEC-1010 by Neil Lovering
• Simple Hacking Tools For Your Own Network – BRKSEC-1008 by Jerry Lin

I really enjoyed these sessions a great deal!!  They were the absolute perfect eye-opener to me!

Neil Lovering had the “Verizon Data Breach Report” in his slides (below).

Its funny because I have seen it before.  To be completely honest I have seen it quite a number of times.  But it was just something about how he presented it.  He got past my not wanting to really “hear” about the risk and the danger and the reality of the security landscape in the world around us.  I paused the VoD on this slide…. paused it and just really took the time to take it all in.

My reaction to this slide?  Lol. This is when the fear began.  Two simple facts on the Continue reading

Worth Reading: Anonymous Speech Takes a Hit

First Amendment protections for anonymous speech online were dealt a serious blow earlier today when the United States Court of Appeals for the Ninth Circuit issued its opinion in United States v. Glassdoor. In its opinion, the Court ruled in favor of the US government’s efforts to compel Glassdoor to unmask anonymous reviews of employers by employees posted on the site. The ripple effects of this case for online speakers could be severe, and with the case having been placed under seal from day one, it’s not surprising that the decision reflects a clear lack of understanding of its potential impact from the Court. — Lisa A Hayes @ Center for Democracy and Technology

IDG Contributor Network: 5 reasons why IT can’t tame the user experience for the network manager

Every vendor today is spewing about the importance of managing the user experience. What this actually means, however, remains a mystery to most, and there are precious few approaches available to help you get a handle on the issue.Good and predictable user experience is no longer negotiable in this age of constant online business communications. Computer networks have effectively become the single most important tool driving corporate productivity.But user experience is one of the most difficult problems to address, especially on enterprise access networks, because each experience is influenced by a long list of moving parts, many of which are increasingly outside the control of IT. To read this article in full, please click here

Worth Reading: Continuous Infrastructure

Continuous delivery (CD) and continuous integration (CI) are two well-known aspects of DevOps. But the CI in vogue today is missing a critical “I:” infrastructure. There was a time when “infrastructure” meant headless black boxes, enormous server rooms, and towering racks—not to mention procurement processes that stretched for months and load estimates that erred on the side of surplus. Then came the virtual machine revolution, which made the infrastructure, well, virtual—and the world has never been the same. We no longer need to manage brick-and-mortar boxes. We can create and destroy, start and stop, upgrade and downgrade machines with just a few clicks. — Girish Managoli @ opensource.com

Europe Elbows For A Place At Exascale Table

When talking about the ongoing international race to exascale computing, it might be easy to overlook the European Union. A lot of the attention over the past several years has focused on the efforts by the United States and China, the world’s economic powerhouses and the centers of technology development.

Through its Exascale Computing Project, the United States is putting money and resources behind its plans to roll out the first of its exascale systems in 2021. For its part, China is planning at least three pre-exascale systems using mostly home-grown technologies, backed by significant investments by the Chinese …
