Krylov.jl: Elevating JuliaSmoothOptimizers to New Heights!

Excitement is buzzing within the JuliaSmoothOptimizers community as we proudly announce a significant achievement—the publication of the Krylov.jl paper in the Journal of Open Source Software. Krylov.jl is not just a package; it's a success story that showcases the growing impact of our community in the world of computational mathematics.

Krylov.jl is a powerhouse of carefully selected Krylov methods designed to tackle a diverse range of linear problems. Initiated by Alexis Montoison and Dominique Orban, Krylov.jl is more than a success—it's a testament to the collaborative spirit of our community. This work was part of Alexis' PhD work that he successfully defended this Winter ✨.

From Theory to Practice: Your Go-To Toolbox

Imagine having the largest collection of Krylov processes and methods at your fingertips. With six processes and an impressive thirty-five methods (as of today), Krylov.jl is breaking records and setting a new standard. Whether you're dealing with square systems, linear least-squares problems, or generalized saddle-point systems, this toolbox has got you covered.

Precision Unleashed: Any System, Anywhere

Krylov.jl understands that multiprecision is crucial and supports real and complex data in any floating-point system that Julia supports. From single and double precision to extended precision using GNU MPFR, this toolbox adapts to your needs, ensuring accuracy in every computation.

GPU Magic: Transforming Bottlenecks into Speedways

Krylov methods are renowned for their parallelizability, and Krylov.jl takes this to the next level with seamless GPU computing support. Whether you're working with CUDA, ROCm, or oneAPI, our toolbox leverages the power of Julia's multiple dispatch and broadcast features, making your linear problems soar on GPUs.

Linear Operators: Redefining Efficiency

In the world of high-dimensional problems, building and storing matrices can be impractical. Krylov.jl introduces the concept of linear operators, allowing you to represent Hessians and Jacobians without the computational baggage. It's a game-changer for nonlinear optimization, reducing computation time and memory requirements.

Performance Boost: In-Place Methods and Beyond

Memory allocations slowing you down? Not with Krylov.jl! All solvers come with in-place variants, minimizing those pesky allocations and deallocations. And when it comes to performance, we've got you covered—dispatching operations to BLAS routines and dynamically switching between backends for the win.
