NERSC director Kathy Yelick shares insights on programming petascale systems like the Hopper system.
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 March 2009, Cray announced the Cray XT5m system, a compatible midrange extension of the high-end Cray XT5 product line that was first to break the sustained petaflop performance barrier on real-world applications. In this interview, HPCwire asked Barry Bolding, Cray’s vice president of scalable systems, for an update on the midrange product.
