How many ways to send?

Pop quiz, hotshot: how many types of sends are there in MPI?

Most people will immediately think of MPI_SEND.  A few of you will remember the non-blocking variant, MPI_ISEND (where I = “immediate”).

But what about the rest — can you name them?

Here’s a hint: if I run “ls -1 *send*c | wc -l” in Open MPI’s MPI API source code directory, the result is 14.  MPI_SEND and MPI_ISEND are two of those 14.  Can you name the other 12?

Enterprise Video & Medianet at Cisco Live London

If I had to summarize Cisco Live London in one word, I choose “educational”. In the four days I was at Cisco Live London, I had the opportunity to meet our local medianet experts, Patrick Charretour and Peter Matthews, learn about our broad core network portfolio, and listen to the challenges our customers face as they use video solutions in their organization.  Whether customers are deploying video surveillance, signage, or telepresence, each seemed to want help on where to start with their deployment and wondering if medianet would be the solution.

Conversations at the medianet station were engaging and all seem to start with the same question, “What is medianet?”.  Medianet is Cisco’s end-to-end video architecture, optimize for the pervasive deployment of video. So at Cisco Live, we demonstrated how Cisco’s medianet architecture makes it easier for you to plan, deploy and manage video in your organization.  Using Cisco TelePresence EX 90 systems, we demonstrated the performance monitoring and mediatrace capabilities in a Cisco medianet, allowing application and network managers to easily identify and troubleshoot issues that may occur during a telepresence call.  We also showed a new capability, but since we haven’t officially launched it, I can’t say much.  You’ll just have to go to Interop Las Vegas or Cisco Live San Diego to find out.
