EuroMPI 2013: CFP

November 30, 2012 at 6:07 pm PST

It’s that time of year again — time to start preparing for Euro MPI 2013!

Next year, we’ll be heading to Madrid, Spain September 15-18.   Here’s a snipit from the call for papers:

Topics of interest include, but are not limited to:

  • MPI implementation issues and improvements
  • Extensions to and shortcomings of MPI
  • Tools and environments for MPI
  • Hybrid and heterogeneous programming with MPI and other interfaces

Come join us for some sangria in scenic Madrid next year.  Submission deadline is March 29th.

Cisco ultra low latency support for MPI

November 16, 2012 at 9:42 am PST

My team demonstrated our new ultra-low latency Ethernet solution in the Cisco booth at SC this past week (it was so busy that I didn’t get to post this until it was all over!).

The short version is that we have implemented operating system bypass and NIC hardware offload via the Linux OpenFabrics verbs API stack. We call it “userspace NIC”, or “USNIC”.

But let’s cut to the chase — what’s the performance?  Let’s break it down:

Cisco @SC2012

November 9, 2012 at 6:24 am PST

Going to Salt Lake City for Supercomputing 2012 next week?  So are we!

Be sure to drop by and see us in the Cisco booth (#2517).  I’ll be there, demonstrating and talking about our latest developments in ultra low latency Ethernet (hint: it includes 250ns port-to-port Ethernet switch latency and our latest MPI/OS-bypass technology on the Cisco Virtualized NIC in Cisco UCS servers).

In short: everyone assumes Ethernet is slow.  Everyone is wrong.

I’ll also be co-hosting the Open MPI State of the Union BOF with George Bosilca from the University of Tennessee in the Wednesday noon timeslot (room 155B).

I’ll also be one of the judges in the Student Cluster Competition.  Be sure to drop by and see the teams; they make an amazing effort every year.

Finally, this isn’t really SC-related, but Cisco will be hosting the MPI Forum meeting again in December.  Register and come join in the discussion that shapes HPC for the next 10 years.
