Hi guys, i understood from the documentation that I can use LinearSolve with Krylov in both CPU and GPU. i am trying to solve a sparse linear system Ax=b as...

Passing a `CuSparseMatrixCOO` matrix to `LinearProblem` gives incorrect results

5

Here's an MWE: ```julia using Statistics using SparseArrays using LinearSolve using CUDA using CUDA.CUSPARSE n = 10 A_cpu = spdiagm(-1 => ones(n-1), 0 => -2*ones(n), 1 => ones(n-1)) colptr, rowval,...

Allow to distinguish between Pardiso and MKLPardiso

1

Hi, At the moment, in the Pardiso extension: https://github.com/SciML/LinearSolve.jl/blob/3881230cf34d6a0414e8ca12de1280d00f5a0e8b/ext/LinearSolvePardisoExt.jl#L28 it is not possible to distinguish between Pardiso and MKLPardiso Since MKL Pardiso was forked off in the early 2000's these...

`cache.isfresh` can be a confusing name

2

It seems like `cache.isfresh` is used to check if the cache is out of date, e.g. in the docs: https://github.com/SciML/LinearSolve.jl/blob/3881230cf34d6a0414e8ca12de1280d00f5a0e8b/docs/src/advanced/developing.md?plain=1#L25-L33 But I think a fresh cache usually refers to one...

Hello, I can't precompile DifferentialEquations pointing me to an issue with LinearSolve, and several other packages( Also not pre-compiling: StochasticDiffEq.jl, OrdinaryDiffEq.jl). I was trying to add the package standalone, and...

Unified handling of preconditoners and factorizations ?

Hi, I see that 2.0 is underway, so this may be an occasion to have some discussion about the API. The current API handles preconditioners and direct solvers very differently....

Using HYPRE solver in DifferentialEquations.jl causes stack overflow

1

Stack overflow at https://github.com/SciML/LinearSolve.jl/blob/main/src/common.jl#L160-L162 I think some dispatches are missing. E.g. I had to overload `LinearSolve.needs_concrete_A(::HYPREAlgorithm)` to come this far. Reproducer ```julia using DifferentialEquations, HYPRE, MPI, LinearSolve MPI.Init() HYPRE.Init() function...

Extra memory usage that cannot be released from GC when reuse_symbolic=true

Hi, I am now designing a package that needs to solve multiple times of `A \ b`, but with different `A`s. This package really benefits a lot, thanks for the...
