Debugging concurrent programs is difficult. This is primarily because the inherent non-determinism that arises because of scheduler interleavings makes it hard to easily reproduc...
We present a general scheme for virtualizing main memory errorcorrection mechanisms, which map redundant information needed to correct errors into the memory namespace itself. We ...
To make efficient use of CMPs with tens to hundreds of cores, it is often necessary to exploit fine-grain parallelism. However, managing tasks of a few thousand instructions is ...

This paper introduces a new abstraction to accelerate the readbarriers and write-barriers used by language runtime systems. We exploit the fact that, dynamically, many barrier exe...
Aggressive technology scaling provides designers with an ever increasing budget of cheaper and faster transistors. Unfortunately, this trend is accompanied by a decline in individ...

Computer systems with virtual memory are susceptible to design bugs and runtime faults in their address translation (AT) systems. Detecting bugs and faults requires a clear speci...

The behavior of a multithreaded program does not depend only on its inputs. Scheduling, memory reordering, timing, and low-level hardware effects all introduce nondeterminism in t...

Multicore technology is making concurrent programs increasingly pervasive. Unfortunately, it is difficult to deliver reliable concurrent programs, because of the huge and non-det...
DRAM is facing severe scalability challenges in sub-45nm technology nodes due to precise charge placement and sensing hurdles in deep-submicron geometries. Resistive memories, suc...

Temperature is a dominant factor in the performance, reliability, and leakage power consumption of modern processors. As a result, increasing numbers of researchers evaluate therm...
