The thinking was that researchers from government institutions, universities and industry could use these testbeds to experiment with disruptive network technologies without interfering with traffic on a major production network.

Now in its 20th year, the event focuses on the latest developments in the field with a special emphasis on how the technology is advancing in the realm of supercomputing and large-scale datacenters. The event covers both chip-to-chip interconnects as well as networking fabrics that bind whole systems and datacenters together.

And although Brocade was not the first vendor to market with such gear, it has quickly become one of the largest providers of 100 GbE ports, a lot of which are ending up in science and research networks. Organizations such as CERN, Indiana University and the Howard Hughes Medical Center are already employing the technology to power performance-demanding applications
John D’Ambrosia, chair of the Ethernet Alliance weighed in on the focus of the Ethernet Alliance at SC11, expanding on their interoperability goals and describing the overall role of Ethernet technologies in HPC.
It was a bit of a surprise when QLogic beat out Mellanox as the interconnect vendor on the NNSA’s Tri-Lab Linux Capacity Cluster 2 contract. Not only was Mellanox the incumbent on the original Tri-Lab contract, but it is widely considered to have the more complete solution set for InfiniBand. Nevertheless, QLogic managed to win the day, and did so with somewhat unconventional technologies.
In an effort to evaluate creative methods of participating in large scientific projects, research out of Brigham Young University done by Spencer Taylor examined the open source software HTCondor, which makes use of computing power from idle computers to perform jobs on a local network.
