Title:  Towards Energy Efficient Scientific Computing

Abstract:
We consider the problem of achieving energy efficient sparse scientific 
computing by characterizing the interactions between application and 
architecture attributes toward energy and performance trade-offs. Our 
goal is to improve the energy efficiency while maintaining or improving 
application performance. Toward this, we investigate energy and 
performance improvements at three levels of abstraction: (i) global 
application workload balancing across multiprocessor nodes, (ii) global 
inter node opportunities for energy improvements, such as: dynamic 
voltage frequency scaling (DVFS), interconnect link scaling and just in 
time computation; and (iii) single node on-chip optimizations for 
power-aware high performance computing, such as: adaptive hardware 
selection and novel cache architectures for multi-core processors.
