As our Dark Silicon study shows, the benefits from continuous transistor scaling are diminishing due to energy and power constraints. Further, our results show that the current paradigm of general-purpose processors, multicore processors, will fall significantly short of historical trends of performance improvements in the next decade. These shortcomings may drastically curtail computing industry from continuously delivering new capabilities, the backbone of its economic ecosystem.
Computer Architecture Seminar: Approximate Acceleration: Trading off Certainty for Efficiency and Speed AbstractTuesday, December 2, 2014 - 4:00pmHadi EsmaeilzadehGeorgia Institute of Technology
Tuesday, December 2, 2014 - 4:00pm to 5:00pmAssociate Professor Laura McLay, PhDDepartment of Industrial & Systems Engineering, UW-Madison
Laura McLay will speak on "Delivering Emergency Medical Services: Research, Application and Outreach." Dr. McLay will describe her research projects that apply operations research methodologies to emergency medical services. These projects have resulted in several key insights into optimally using scarce public resources for responding to health emergencies.

Cryptography inherently relies on mathematical problems that are
conjectured to be infeasible, e.g., factoring large integers.
However, most of the commonly used problems result in cryptosystems
that are too inefficient or inflexible for use in many environments.
Moreover, all of the commonly used problems behind today's public-key
cryptography can in principle be broken by quantum computers.

Virtualization provides value for many workloads, but its cost rises for workloads with poor memory access locality. This overhead comes from translation lookaside buffer (TLB) misses where the hardware performs a 2D page walk (up to 24 memory references on x86-64) rather than a native TLB miss (up to only 4 memory references). The first dimension translates guest virtual addresses to guest physical addresses, while the second translates guest physical addresses to host physical addresses.
