Union: A Unified HW-SW Co-Design Ecosystem in MLIR for Evaluating Tensor Operations on Spatial Accelerators

no code implementations15 Sep 2021 Geonhwa Jeong, Gokcen Kestor, Prasanth Chatarasi, Angshuman Parashar, Po-An Tsai, Sivasankaran Rajamanickam, Roberto Gioiosa, Tushar Krishna

The algorithms and accelerator cost models are connected via a novel mapping abstraction that captures the map space of spatial accelerators which can be systematically pruned based on constraints from the hardware, workload, and mapper.

Concentric Spherical GNN for 3D Representation Learning

no code implementations18 Mar 2021 James Fox, Bo Zhao, Sivasankaran Rajamanickam, Rampi Ramprasad, Le Song

Learning 3D representations that generalize well to arbitrarily oriented inputs is a challenge of practical importance in applications varying from computer vision to physics and chemistry.

Accelerating Finite-temperature Kohn-Sham Density Functional Theory with Deep Neural Networks

no code implementations10 Oct 2020 J. Austin Ellis, Lenz Fiedler, Gabriel A. Popoola, Normand A. Modine, J. Adam Stephens, Aidan P. Thompson, Attila Cangi, Sivasankaran Rajamanickam

We present a numerical modeling workflow based on machine learning (ML) which reproduces the the total energies produced by Kohn-Sham density functional theory (DFT) at finite electronic temperature to within chemical accuracy at negligible computational cost.

How Robust Are Graph Neural Networks to Structural Noise?

no code implementations21 Dec 2019 James Fox, Sivasankaran Rajamanickam

Graph neural networks (GNNs) are an emerging model for learning graph embeddings and making predictions on graph structured data.

An Algebraic Sparsified Nested Dissection Algorithm Using Low-Rank Approximations

1 code implementation9 Jan 2019 Léopold Cambier, Chao Chen, Erik G Boman, Sivasankaran Rajamanickam, Raymond S. Tuminaro, Eric Darve

We evaluate the algorithm on some large problems show it exhibits near-linear scaling.
