With the right techniques, multicore architectures may be able to continue the exponential performance trend that elevated the performance of applications of all types for decades...

A large number of user requests execute (often concurrently) within a server system. A single request may exhibit fluctuating hardware characteristics (such as instruction comple...
Growing transistor counts, limited power budgets, and the breakdown of voltage scaling are currently conspiring to create a utilization wall that limits the fraction of a chip tha...

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...
