How many network links do you have for MPI traffic?

July 19, 2013 at 5:00 am PST

If you’re a bargain basement HPC user, you might well scoff at the idea of having more than one network interface for your MPI traffic.

“I’ve got (insert your favorite high bandwidth network name here)! That’s plenty to serve all my cores! Why would I need more than that?”

I can think of (at least) three reasons off the top of my head.

Cisco Service Discovery Gateway – Enabling Zeroconf in Enterprise Networks

Cisco Service Discovery Gateway – Enabling Zeroconf in Enterprise Networks

I’ll admit it: I’m what others call an Apple fan boy. One of the many reasons for being one is the polished user experience and the ease-of-use of their products. One of the underlying technologies that enables the user to discover devices and services on the network is Zeroconf or, as Apple calls it, Bonjour.

Zeroconf consists of three major components:

  • Address auto configuration,
  • Naming –and–
  • Service discovery.

If your network doesn’t have a DHCP server or you haven’t statically assigned an IP address to your host, most operating systems will use an automatic private IP address. I’m not going into much detail on address auto configuration except that this is typically done using a technique called APIPA (Automatic Private IP Addressing) for IPv4 the host will use the famous 169.254.0.0/16 addresses or, in case of IPv6, by using link-local addresses only (FE80::/10) which has been designed into IPv6 as a basic functionality from day one. Also, naming is not of much of a concern in the context of this discussion. However, it is worth mentioning that Zeroconf names can contain Unicode characters and whitespace, which can make those names a lot more user friendly and meaningful contrary to pure DNS names.

The more interesting part, as it pertains to Zeroconf, is the service discovery. Read More »

ACE Network: Building Stronger Team Relationships with Video Calls

In my job as Program Manager for the Cisco IT Advanced Cisco Experience (ACE) Program, I need to meet regularly with my team members, leaders of the user communities we serve, and other colleagues who are all over the world.

Sure, I could handle some of these interactions with an audio-only phone call, but I’d miss the face-to-face interaction and I don’t have time to travel to meet each team in person. But today I conduct many of these small group meetings and individual conversations as HD-quality video calls over the personal Cisco TelePresence EX90 endpoint that’s on my desk, using the ACE network video services.
