Application Performance Modeling via Tensor Completion
Edward Hutter, Edgar Solomonik
Performance tuning, software/hardware co-design, and job scheduling are among the many tasks that rely on models to predict application performance. We propose and evaluate low-ran…

Accelerating Distributed-Memory Autotuning via Statistical Analysis of Execution Paths
Edward Hutter, Edgar Solomonik
The prohibitive expense of automatic performance tuning at scale has largely limited the use of autotuning to libraries for shared-memory and GPU architectures. We introduce a fram…

Communication-avoiding Cholesky-QR2 for rectangular matrices
Edward Hutter, Edgar Solomonik
Scalable QR factorization algorithms for solving least squares and eigenvalue problems are critical given the increasing parallelism within modern machines. We introduce a more gen…
