Engineering Code Scales Across 200,000 Cores on Cray Super

Teams at Saudi Aramco using the Shaheen II at King Abdullah University of Science and Technology (KAUST) supercomputer have managed to scale ANSYS Fluent across 200,000 cores, marking top-end scaling for the commercial engineering code.

The news last year of a code scalability effort that topped out at 36,000 cores on the Blue Waters machine at the National Center for Supercomputing Applications (NCSA) was impressive. That was big news for ANSYS and NCSA, but also a major milestone for Cray. Just as Blue Waters is a Cray system, albeit one at the outer reaches of its lifespan (it was installed …

Transforming IT Security in Three Key Steps

Several years ago, the CEO of a Fortune 100 company remarked: “If you went to bed last night as an industrial company, you’re going to wake up this morning as a software and analytics company.”

Today, these words are more true than ever—but so is the reality that the digital transformation in business has also given rise to significant changes across the IT landscape and, in turn, significant new challenges for IT security.

As people, devices, and objects become more connected, protecting all these connections and environments has become a top priority for many IT organizations. At the same time, it’s also become one of their biggest challenges. Securing each and every interaction between users, applications, and data is no easy feat—especially when you consider that securing these interactions needs to be done across environments that are constantly changing and increasingly dynamic.

So how do you mitigate risk in a world where IT complexity and “anytime, anywhere” digital interactions are growing exponentially? For organizations that are embracing cloud and virtualized environments, three common-sense steps—enabled by a ubiquitous software layer across the application infrastructure and endpoints that exists independently of the underlying physical infrastructure—are proving to be key for providing Continue reading

What SDN is and where it’s going

Forrester analyst Andre Kindness says a lot of clients ask him how they should think about software-defined networking (SDN), which has been heralded for years as the next great thing in the industry.SDN – which is an architecture approach, not a specific product - has traditionally been thought of as virtualizing data center networks. This typically means separating the management of the control plane of network devices from the underlying data plane that forwards network traffic. Using a software-defined system to control this disaggregation brings many benefits, including increased network management flexibility and being able to more easily implement fine-grained security policies.To read this article in full or to leave a comment, please click here

3 ways to track people using location-based services

There are lots of motivations driving organizations to install location-tracking technologies. The obvious driver is to find things, especially things on wheels, such as medical equipment in a hospital. It can also be smart to keep tabs on things in transit, such as a container. But the biggest reason to track things is simply because we can. We can also use these technologies to track people. Some solutions such as facial recognition can literally track people, but usually we just track a device someone might be carrying. We can now literally track the customer’s journey (through a retail store). There’s a popular misconception that global positioning satellites (GPS) are usable inside, but they range from worthless to unhelpful. GPS satellite signals require a direct line of sight to multiple satellites. To read this article in full or to leave a comment, please click here

Worth Reading: Ethernet Getting back on Moore’s Law

It would be ideal if we lived in a universe where it was possible to increase the capacity of compute, storage, and networking at the same pace so as to keep all three elements expanding in balance. The irony is that over the past two decades, when the industry needed for networking to advance the most, Ethernet got a little stuck in the mud. —The Next Platform

Oracle beefs up cloud sales team with 1,000 EMEA openings

Oracle is the latest legacy software vendor looking to reorganise its sales teams to be more focused on cloud services, as it announces 1,000 job openings in EMEA.Oracle is targeting "people from diverse backgrounds and profiles with between two to six years work experience", the official press release states.This follows some positive financial results for Oracle, as it posted a 66 percent year-on-year growth in cloud revenues for Q4 2016. That figure comes in at $1.4 billion and includes PaaS, IaaS and SaaS, which has been boosted by the recent NetSuite acquisition. By comparison AWS posted revenues of $3.66 billion in its latest results back in April.To read this article in full or to leave a comment, please click here

An Introduction to oVirt Ansible Roles

Today I would like to share with you some of the integration work with Ansible 2.3 that was done in the latest oVirt 4.1 release. The Ansible integration work was quite extensive and included Ansible modules that can be utilized for automating a wide range of oVirt tasks, including tiered application deployment and virtualization infrastructure management.

While Ansible has multiple levels of integrations, I would like to focus this article on oVirt Ansible roles. As stated in the Ansible documentation: “Roles in Ansible build on the idea of include files and combine them to form clean, reusable abstractions – they allow you to focus more on the big picture and only dive into the details when needed.”

We used the above logic as a guideline for developing the oVirt Ansible roles. We will cover three of the many Ansible roles available for oVirt:

For each example, I will describe the role's purpose and how it is used.

oVirt Infra

The purpose of this role is to automatically configure and manage an oVirt datacenter. It will take a newly deployed- but not yet configured- oVirt engine (RHV-M for RHV users), hosts, and storage and Continue reading

2 reasons to migrate off of Microsoft Exchange Server

A few weeks back, I wrote that “choosing Microsoft Windows for your organization should get you fired.”It’s a statement that, while certainly a bit on the inflammatory side, I completely stand by—mostly due to the known insecure nature of running Windows as a server operating system.What I didn’t do was give specific examples of what to move your existing Windows-based infrastructure to. Sure, the obvious answer for most SysAdmins is simply “migrate the servers over to Linux.” But what about specific server applications that your organization might already rely upon? That’s a whole other can of worms.To read this article in full or to leave a comment, please click here

The Trials And Tribulations Of IBM Systems

IBM is a bit of an enigma these days. It has the art – some would say black magic – of financial engineering down pat, and its system engineering is still quite good. Big Blue talks about all of the right things for modern computing platforms, although it speaks a slightly different dialect because the company still thinks that it is the one setting the pace, and therefore coining the terms, rather than chasing markets that others are blazing. And it just can’t seem to grow revenues, even after tens of billions of dollars in acquisitions and internal investments over …
