Splines recover lapack backend

Open blegouix opened this issue 2 years ago • 2 comments

Matrix classes support strided m-rhs (but spline_builder still involves transpositions, to get DimI as coalescent dimension for Ginkgo and DimI as contiguous one for Lapack. It may be improved in another MR).
Schur complement and several banded matrixes are implemented.
Ginkgo and Lapack backends are both available
Tests for matrices and both backends

Note: performance is pretty bad on GPU because we perform CPU<->GPU deepcopies and CPU Lapack calls in the solver. It is adressed in the #276.

I put it in draft until CI passes

I suggest to split this MR in 2 parts, a first part with only Matrix related files and an other one related to splines

@blegouix Shall we keep the branch ? If so can you rename it following our convention ?

I prefer to keep them at least while the others are not merged, thx for the remind
