Network interoperability lab

I found out about a place where networking interoperability is the main focus.  It happens to be where I live in New Hampshire.

HPC for high IO


Enabled by Cluster family of EC2 instances, which includes:

  • Cluster Compute instances: cc1.4xlarge,cc2.8xlarge
  • Cluster GPU instances : cg1.4xlarge
  • New c3.large, c3.xlarge, c3.2xlarge, c3.4xlarge and c3.8xlarge
Attributes of these instances:


  • 10 Gbps Ethernet
  • Latency and bandwidth about 10X better than “EC2 Classic” 
  • Uses jumbo frames between cluster instances
  • New EC2 API: Placement Groups. A placement group is a logical cluster 


Because HPC instance types have 10 Gbps networks, using 20 volumes attached to an HPC instance you can achieve in the neighborhood of 100 IOPS using 4K PIOPS volumes.

Network speeds and Moore's Law


The speed of the Ethernet has increased from 1 Gbps in 1997 to 100 Gbps in 2010; this increase is slightly slower than the Moore law for traffic [251] which would require 1 Tbps Ethernet by 2013.
