Structural plasticity of the brain describes the creation of new and the deletion of old synapses over time.

Learning to Make Compiler Optimizations More Effective

no code implementations24 Feb 2021 Rahim Mammadli, Marija Selakovic, Felix Wolf, Michael Pradel

Applying the transformations that our model deems most favorable prior to compilation yields an average speedup of 1. 14x.

Static Neural Compiler Optimization via Deep Reinforcement Learning

no code implementations20 Aug 2020 Rahim Mammadli, Ali Jannesari, Felix Wolf

Provided with sub-sequences constituting LLVM's O3 sequence, our agent learns to outperform the O3 sequence on the set of source codes used for training and achieves competitive performance on the validation set, gaining up to 1. 32x speedup on previously-unseen programs.

A Fast Isogeometric BEM for the Three Dimensional Laplace- and Helmholtz Problems

no code implementations30 Aug 2017 Jürgen Dölz, Helmut Harbrecht, Stefan Kurz, Sebastian Schöps, Felix Wolf

We present an indirect higher order boundary element method utilising NURBS mappings for exact geometry representation and an interpolation-based fast multipole method for compression and reduction of computational complexity, to counteract the problems arising due to the dense matrices produced by boundary element methods.
