Ren et al (2010) Google-Wide Profiling: A Continuous Profiling Infrastructure for Data Centers (IEEE Micro)

June 21, 2011 paper

Google-Wide Profiling is theoretically an extension of the Digital Continuous Profiling Infrastructure (DCPI) [Anderson et al, 1997] to data centers. It is a continuous profiling infrastructure that samples across machines in multiple data centers and collects various events. GWP collects profiles on stack traces, hardware events, lock contention profiles, heap... [more]

Abts et al (2010) Energy Proportional Datacenter Networks (ISCA)

May 30, 2011 paper

A paper from Google describing how to make data center network energy proportional, i.e. the energy consumption in watts is proportional to the utilization. The current status is that, servers are more power-hungry than network because of the over-subscription. However, server is also easier to be energy proportional. Network equipments,... [more]
