proposed a new industry benchmark to measure the power efficiency for the
High-Productivity Computing (HPC) segment, which includes data center
computing. This metric, the Green Computing Performance Index (GCPI), measures
is to reduce the need of data centers to be built near hydroelectric
dams, or even at
sea. More efficient computing reduces the power consumption of not
only the electronics but also the power required to cool them.
optimistic that the GCPI will spawn needed dialogue in the industry,
calling companies, including SiCortex, to live up to their claims surrounding
green HPC,” said Chris Stone, president and CEO of SiCortex.
the money quote right there. Maybe it’s not the end-all measurement, but
at least it raises awareness and helps their customers make informed decisions.
has a vested interest of course. They sell low-power high-performance
computing systems. The approach they took is exactly what is needed –
building power into everything from the ground-up, not as an
afterthought. The way they designed their processor architecture, the
communication fabric, even their own flavor of Linux – all took power
efficiency into account.
is also the approach we have taken here at Cadence. I know our “green
campaign” has been the first advertising campaign around this, but our product
teams built power optimization and awareness into our tools from the
ground-up. This makes it easier to for instance, minimize power in the
context of aggressive performance goals, or to verify power functionality the
same way and at the same throughput as any other function your chip
performs. Power can no longer be an afterthought or a bolt-on. And
at the same time, it can’t be a barrier to achieving your other goals.
needs to have this dialogue – to understand the power efficiency of their
approach, and to make all of their architecture, design, and implementation
decisions in this context.
