The slides below are from my presentation at EuroMPI’13 about Open MPI’s flexible process affinity interface (in OMPI 1.7.2 and later). I described this system in a prior blog entries (one, two, three), but many people keep asking me about it.
Josh Hursey from U. Wisconsin, LaCrosse, wrote this IMUDI paper about the interface (IMUDI is a sub-workshop of EuroMPI focusing on end-user issues) to get a little more publicity and awareness of this process affinity system. Specifically, we designed this affinity system so that we could get feedback from real end users about what is useful and what is not.

This past week, the Meeting of the Minds convened in Toronto, Canada with more than 375 invited CXOs debating the convergence of urban sustainability and connected technologies. During the three-day summit, a variety of smart public policies and breakthrough technology innovations were presented by leading innovators.
The solutions showcased– from lighting to energy grids to parking – are all designed to enable cities and metro-regions to better respond to increasingly complex challenges: urban planning, city design, network technology and infrastructure. As a keynote speaker, I had the opportunity to address a topic that was top of mind for many of these leaders – The Smart City Powered by the Internet of Everything (IoE).

Last month, the Internet of Things was added to Oxford Dictionaries Online. IoT was added along with such august terms as BYOD, Bitcoin, and even selfie. While the ODO isn’t the OED – it’s the younger, hipper sibling focused on current English and modern meanings – this addition is just one more datapoint on the growing awareness around the coming Internet of Things.
Internet of things has been around as a term since about 1999, however, it’s recent popularity is due to a few emerging trends. In the consumer space there’s been wide adoption of connected products such as smart thermostats and intelligent pedometers. In the enterprise (and here I am using enterprise to represent many types of larger organizations – including local and national governments, non-profits, academia and companies) we’ve seen the rise of BYOD which you could argue is the first mainstream IoT form-factor.

Cisco Catalyst 2960-X is our greenest Catalyst access switch ever. If all similar switches shipped in 2012 were as energy efficient as Catalyst 2960-X, you would save enough energy to power every household in San Francisco for more than 3 years. Here’s how:
- At power up, Catalyst 2960-X consumes lower power than other comparable switches.
- Cisco EnergyWise monitors and controls the power consumption of PoE and PoE+ devices connected to the switch. You can turn off IP phones and wireless access points automatically after business hours.
- Energy Efficient Ethernet provides power savings when there is no traffic on switch ports. This saves about 15 watts for a 48 port-switch and 8 watts for a 24 port-switch.
- Downlink Hibernation Mode shuts down the downlink interface to save half watt per port when the connected devices are not in use, for example, after the office hours.
- Switch Hibernation Mode puts the switch to sleep mode during off hours and weekends. In this mode, the switch consumes as low as 6 watts, compared to 47 watts in active mode.
Collectively, these green features can reduce power consumption by up to 80%. Read More »

As a working mom of two of the best and brightest kids (no bias here!) I couldn’t be prouder that Cisco again made the Working Mother 100 Best Companies list. When you think about it though, “Mother” is a bit of a misnomer here. Really most Cisco employees, about 99 percent in fact, benefit from the flexible work practices that have become the hallmark of our corporate culture and one of the things that makes Cisco such a great place to work.
Progressive, flexible work policies are table stakes, but lets not forget about the technology that has made it all possible. I remember back in the day, I was working late one night at home when my dial up (yes, dial up) malfunctioned. I had to hop in the car close to midnight and drive to the Cisco office just to log onto the corporate network and send an email. Today, thanks to the power of the network (do I sound like a commercial?) I can work from anywhere, at anytime and be productive.
While flexibility is key, it’s not the only thing that Working Mother highlights as a characteristic of a “Best Company.” Check out the complete story for more details.
