The Moore's Law era enjoyed a long run of lithographically-enabled pitch shrinking that
directly reduced the cost per (von Neumann) function, as well as system power and …

The high access latency of DRAM continues to be a performance challenge for
contemporary microprocessor systems. Prefetching is a well-established technique to …

In this paper, we describe the IBM POWER8™ cache, interconnect, memory, and
input/output subsystems, collectively referred to as the “nest.” This paper focuses on the …

In recent years, the HPC landscape has shifted away from traditional multi-core CPU
systems to energy-efficient architectures, such as many-core CPUs and accelerators like …

Chiplet-based systems have recently received much attention for scaling-up processing
power in HPC systems due to their high energy efficiency and low cost manufacturing; …

Among the emerging technologies recently proposed as alternatives to the classic CMOS,
quantum-dot cellular automata (QCA) is one of the most promising solutions to design …

Cloud computing has evolved into a promising computing paradigm. However, it remains a
