Avoiding Program Failures Through Safe Execution Perturbations
We present an online framework to capture and recover from program failures and prevent them from occurring in the future through safe execution perturbations. The perturbations a...

Linear analysis and optimization of stream programs
As more complex DSP algorithms are realized in practice, an increasing need for high-level stream abstractions that can be compiled without sacrificing efficiency. Toward this en...
