In recent years, the limits of the multicore approach emerged in the so-called “dark silicon”
issue and diminishing returns of an ever-increasing core count. Hardware manufacturers …

Main memory bandwidth is a critical bottleneck for modern GPU systems due to limited off-
chip pin bandwidth. 3D-stacked memory architectures provide a promising opportunity to …

The open-source and community-supported gem5 simulator is one of the most popular tools
for computer architecture research. This simulation infrastructure allows researchers to …

Increasing demand for power-efficient, high-performance computing has spurred a growing
number and diversity of hardware accelerators in mobile and server Systems on Chip …

Specialized on-chip accelerators are widely used to improve the energy efficiency of
computing systems. Recent advances in memory technology have enabled near-data …

Prior work shows that Rowhammer attacks---which flip bits in DRAM via frequent activations
of the same row (s)---are viable. Adversaries typically mount these attacks via instruction …

Memory channel contention is a critical performance bottleneck in modern systems that have
highly parallelized processing units operating on large data sets. The memory channel is …

Architecture designers tend to integrate both CPUs and GPUs on the same chip to deliver
energy-efficient designs. It is still an open problem to effectively leverage the advantages of …

For over 50 years, Amdahl's Law has been the hallmark model for reasoning about
performance bounds for homogeneous parallel computing resources. As heterogeneous …

Originally developed to support video games, graphics processor units (GPUs) are now
increasingly used for general-purpose (non-graphics) applications ranging from machine …
