Development of Krylov and AMG linear solvers for large-scale sparse matrices on…
This research introduce our work on developing Krylov subspace and AMG solvers on NVIDIA GPUs. As SpMV is a crucial part for these iterative methods, SpMV algorithms for single GPU and multiple GPUs are implemented. A HEC matrix format and a communic...
Generalized Optimal AMG Convergence Theory for Nonsymmetric and Indefinite Probl…
Algebraic multigrid (AMG) is known to be an effective solver for many sparse symmetric positive definite (SPD) linear systems. For SPD systems, the convergence theory of AMG is well-understood in terms of the $A$-norm, but in a nonsymmetric setting,...
Parallel Performance of Algebraic Multigrid Domain Decomposition (AMG-DD)
Algebraic multigrid (AMG) is a widely used scalable solver and preconditioner for large-scale linear systems resulting from the discretization of a wide class of elliptic PDEs. While AMG has optimal computational complexity, the cost of communication...

A subspace constrained randomized Kaczmarz method for structure or external know…
We study a version of the randomized Kaczmarz algorithm for solving systems of linear equations where the iterates are confined to the solution space of a selected subsystem. We show that the subspace constraint leads to an accelerated convergence ra...
An Asymptotic Equivalence between the Mean-Shift Algorithm and the Cluster Tree
Two important nonparametric approaches to clustering emerged in the 1970's: clustering by level sets or cluster tree as proposed by Hartigan, and clustering by gradient lines or gradient flow as proposed by Fukunaga and Hosteler. In a recent paper, w...

Sets, Lists and Noncrossing Partitions
Partitions of [n]={1,2,...,n} into sets of lists are counted by sequence number A000262 in the On-Line Encyclopedia of Integer Sequences. They are somewhat less numerous than partitions of [n] into lists of sets, A000670. Here we observe that the f...

Simulation of White Light Generation and Near Light Bullets Using a Novel Numeri…
An accurate and efficient simulation has been devised, employing a new numerical technique to simulate the derivative generalised non-linear Schrödinger equation in all three spatial dimensions and time. The simulation models all pertinent effects s...

Performance Evaluation of Bitstring Representations in a Linear Genetic Programm…
Different bitstring representations can yield varying computational performance. This work compares three bitstring implementations in C++: std::bitset, boost::dynamic_bitset, and a custom direct implementation. Their performance is benchmarked in th...

Doppler Signatures of the Atmospheric Circulation on Hot Jupiters
The meteorology of hot Jupiters has been characterized primarily with thermal measurements, but recent observations suggest the possibility of directly detecting the winds by observing the Doppler shift of spectral lines seen during transit. Motivate...

There was a big line for this chicken at the buffet, so I’m worried the cook was a bit rushed and didn’t cook it fully Sorry I posted here thats the only cooking subreddit I found that authorizes...
Complete description of polarization effects in emission of a photon by an elect…
We consider emission of a photon by an electron in the field of a strong laser wave. Polarization effects in this process are important for a number of physical problems. A probability of this process for circularly or linearly polarized laser phot...
