Structure-driven optimizations for amorphous data-parallel programs
Irregular algorithms are organized around pointer-based data structures such as graphs and trees, and they are ubiquitous in applications. Recent work by the Galois project has pr...

x-f SENSE: optimal spatio-temporal sensitivity encoding for dynamic MR imaging
For high quality MR imaging of time-varying objects such as beating heart or brain hemodynamics, we need to reduce signal acquisition time without sacrificing the spatial resolut...

Comparing the Optimal Performance of Different MIMD Multiprocessor Architectures
We compare the performance of systems consisting of one large cluster containing q processors with systems where processors are grouped into k clusters containing u processors eac...

Highly-Available, Fault-Tolerant, Parallel Dataflows
We present a technique that masks failures in a cluster to provide high availability and fault-tolerance for long-running, parallelized dataflows. We can use these dataflows to im...

A Formal Framework for Specifying and Verifying Time Warp Optimizations
Parallel and distributed systems are representative of large and complex systems that require the application of formal methods. These systems are often unreliable because implemen...
