Process variation—deviation in parameters from their nominal specifications—threatens to
slow down and even pause technological scaling, and mitigation of it is the way to continue …

We consider a multi-user multi-server mobile edge computing (MEC) network with time-
varying fading channels and formulate an offloading decision and resource allocation …

Dynamic Voltage Frequency Scaling (DVFS) has been the tool of choice for balancing
power and performance in high-performance computing (HPC). With the introduction of …

In recent years, GPU-CPU heterogeneous architectures have been increasingly adopted in
high performance computing, because of their capabilities of providing high computational …

Future many-core microprocessors are likely to be heterogeneous, by design or due to
variability and defects. The latter type of heterogeneity is especially challenging due to its …

Electricity cost is becoming a major portion of Internet data center (IDC)'s operation cost and
large-scale IDCs are becoming important consumers of regional electricity markets. IDC's …

In this paper, we present measured within-die core-to-core Fmax and leakage variation data
for an 80-core processor in 65 nm CMOS and 1) populate a parameterized …

Future microprocessors increasingly rely on an unreliable CMOS fabric due to aggressive
scaling of voltage and frequency, and shrinking design margins. Fortunately, many …

As we approach the exascale era, power has become a primary bottleneck. The US
Department of Energy has set a power constraint of 20MW on each exascale machine. To …

The global energy crisis and environmental concerns (eg global warming) have driven the IT
community into the green computing era. Of clean, renewable energy sources, solar power …
