For this issue,wehave three interesting
articles on the theme of Hot Interconnects.
Such interconnects are an increasing part
of obtaining good performance, especially
in high-end machines, such as those
vying for top spots in the Top 500 list
(http://top500.org). The computing deals
with increasing data volumes in everything
from meteorology and climate to earthquake
prediction to brain modeling to business
analytics and web traffic, so having
appropriate interconnects becomes more
important. Guest Editors Torsten Hoefler,
Patrick Geoffray, Fabrizio Petrini, and Jesper
Larsson Tra¨ ff have done an excellent
job of recruiting and selecting articles on
this topic. I hope you find them as interesting
and informative as I did.
