Linalg improvements #276

Closed kburns closed 10 months ago

kburns commented 10 months ago

This PR includes some improvements to linear algebra using cython routines.

For 2D RBC at (Nx, Nz) = (256, 512), this speeds things up by about 5%, and for 3D HOT at 256^3 it speeds things up by about 4%. Bigger differences on other more anisotropic simulations where inverse Jacobi added a lot.

The old behavior, if desired, is available through the OLD_CSR_MATVECS config option.
