Power Aware Dynamic Provisioning of HPC Networks

Abstract: Future exascale systems are under increased pressure to find power savings. The network, while it consumes a considerable amount of power is often left out of the picture when discussing total system power. Even when network power is being considered, the references are frequently a decade or older and rely on models that lack validation on modern interconnects. In this work we explore how dynamic mechanisms of an Infiniband network save power and at what granularity we can engage these features. We explore th… Show more

“…Improving communication EE consists of three groups of methods: (a) saving network fabric power with power-aware networks (Alonso et al, 2006; Conner et al, 2007; Groves and Grant, 2015; Miwa et al, 2014; Miwa and Nakamura, 2015; Nedevschi et al, 2008; Saravanan et al, 2013, 2014; Totoni et al, 2014a), (b) improving communication EE using energy-aware data transfer algorithms (Alan et al, 2015; Jana and Chapman 2015; Jana et al, 2014a, 2014b, 2014c; Kandalla et al, 2010; Lim et al, 2006; Venkatesh et al, 2015; Vishnu et al, 2013), and (c) decreasing network traffic using communication-avoiding algorithms (Demmel et al, 2013; Grigori et al, 2011).…”

“…Some of these methods depend on energy improvement of compiler techniques (Hsu and Kremer, 2003b;Keramidas et al, 2010;Leon et al, 2015;Saputra et al, 2002). (3) Improving communication EE consists of three groups of methods: (a) saving network fabric power with power-aware networks (Alonso et al, 2006;Conner et al, 2007;Groves and Grant, 2015;Miwa et al, 2014;Miwa and Nakamura, 2015;Nedevschi et al, 2008;Saravanan et al, 2013Saravanan et al, , 2014Totoni et al, 2014a), (b) improving communication EE using energy-aware data transfer algorithms (Alan et al, 2015; Jana and Chapman 2015; Jana et al, 2014aJana et al, , 2014bJana et al, , 2014cKandalla et al, 2010;Lim et al, 2006;Venkatesh et al, 2015;Vishnu et al, 2013), and (c) decreasing network traffic using communication-avoiding algorithms (Demmel et al, 2013;Grigori et al, 2011). (4) Automatic tuning: This category treats a parallel application as a black box and improves its EE by tuning several energy and performance parameters (Balaprakash et al, 2013;Gschwandtner et al, 2014;Jordan et al, 2012;Miceli et al, 2012;Rahman et al, 2011;Tiwari et al, 2012).…”
