Modelling parallel overhead from simple run-time records

Visual Behavior: Mice Run from Overhead Danger

Mice show an innate protective behavior to looming shadows approaching from above: they either run for cover or freeze in place. This newly discovered 'looming response' adds to the repertoire of stereotyped behaviors that can be utilized to study visual pathways.

Run-Time Minimization of Reconfiguration Overhead in Dynamically Reconfigurable Systems

Dynamically Reconfigurable Hardware (DRHW) can take advantage of its reconfiguration capability to adapt at run-time its performance and its energy consumption. However, due to the lack of programming support for dynamic task placement on these platforms, little previous work has been presented studying these run-time performance/power trade-offs. To cope with the task placement problem we have...

Techniques for Reducing the Overhead of Run-Time Parallelization

Current parallelizing compilers cannot identify a significant fraction of parallelizable loops because they have complex or statically insufficiently defined access patterns. As parallelizable loops arise frequently in practice, we have introduced a novel framework for their identification: speculative parallelization. While we have previously shown that this method is inherently scalable its p...
