What Next-Generation Wi-Fi Models Could Mean for Secure Mobility

With the adoption of the Internet of Things and Internet of Everything, advances in mobility and next-generation Wi-Fi are driving faster speeds, higher signal quality and more reliable connectivity. With the upcoming ratification of the two waves of the 802.11ac Wi-Fi standard, how are emerging Wi-Fi models creating new security features that are defining the next-generation Wi-Fi experience?

Next Generation Wi-Fi Models

Migration to the 5 GHz-only 802.11ac is quickly becoming a reality. In a recent article by Lisa Phifer, Chris Spain, Vice President of Product Marketing for Cisco’s Wireless Networking Group, discusses more about how this migration will drive a shift in mobile device support for 5 GHz. “An increasing percentage of new mobile devices provide dual-band capability, and they generally prefer the less congested 5 GHz band,” Spain said. New Wi-Fi models, like those listed below, can help drive mobile devices to the 5GHz band:

The Importance of Executive Sponsorship

Executive sponsorship is one of the most important non-technical aspects of a project. Everyone knows about the technical: do we have rack space, is there enough power, did fibers get ordered, did the equipment ship, are the cut sheets ready? But rarely is thought given to the people aspect of projects.

What is Executive sponsorship? Executive sponsorship by definition is a role in project management, usually filled by the senior member of the project board and often the chair. The project sponsor will be a senior executive in a corporation (often at or just below board level) who is responsible to the business for the success of the project. Each company has a different structure and it will mean something different in each case, but the concept is the same for the majority. At our company the primary sponsor was the CIO.Executive Sponsorship

Digital Transformation: Is Your Company Making the Pivot?

December 18, 2013 at 4:24 pm PST

80% of survey respondents [administered by MIT/Sloan and Cap Gemini] believe that their companies need to go through a significant digital transformation. However, 63% of those respondents also believe that their current pace is too slow.

Sound familiar? Is your company moving too slowly? Are you moving at all?

I heard these stats while attending the recent Digital Leaders Summit in San Francisco. Aimed at those responsible for guiding their enterprises into the new digital future, the summit highlighted trends, best practices and case studies from a number of media and other companies including leaders from The New York Times, The Economist, Turner Broadcasting, Jump Associates, Coca-Cola, The LA Times, Politico, and others.

Open MPI: Binding to core by default

December 18, 2013 at 12:55 pm PST

After years of discussion, the upcoming release of Open MPI 1.7.4 will change how processes are laid out (“mapped”) and bound by default.  Here’s the specifics:

  • If the number of processes is <= 2, processes will be mapped by core
  • If the number of processes is > 2, processes will be mapped by socket
  • Processes will be bound to core
  • MPI_COMM_WORLD ranks will be assigned by slot

These are all the default values — they, of course, can be changed by the user via mpirun CLI options, environment variables, etc.
