	Commit message (Collapse)	Author	Age
*	Switch to external ndarray library.	Anton Khirnov	2020-06-25
\|
*	egs: constify a function argument	Anton Khirnov	2019-06-14
\|
*	egs: add support for MPI-based multi-component solves	Anton Khirnov	2019-05-23
\|
*	Make the ghost points explicit in prolongation	Anton Khirnov	2019-05-21
\|
*	egs: allow the same context to be used for both relaxation and exact solves	Anton Khirnov	2019-05-06
\|
*	egs: merge residual calc and correct when possible	Anton Khirnov	2019-04-24
\| \| \| \| \|	Also, merge the reflect boundary condition into residual calc+add. Improves performance due to better locality.
*	Add and use a new timer API.	Anton Khirnov	2019-04-19
\|
*	mg2d: extend stats logging	Anton Khirnov	2019-04-01
\|
*	egs_exact: do not construct the matrix more often than necessary	Anton Khirnov	2019-03-26
\| \| \| \|	It does not change unless the diff coeffs change.
*	egs_exact: avoid explicit matrix transpoe	Anton Khirnov	2019-03-26
\|
*	egs: add more timers	Anton Khirnov	2019-03-25
\|
*	ell_grid_solve: switch to ndarray in its external API	Anton Khirnov	2019-03-22
\|
*	mg2d: print stats properly for exact solves	Anton Khirnov	2019-02-02
\|
*	mg2d: account for effect of the ~u term on the relaxation factor	Anton Khirnov	2019-01-29
\| \| \| \| \|	The maximum allowed time step in the presence of a -K * u term goes like 2 (dx 2) / (4 + K (dx 2))
*	Solve the discretized system exactly on the coarsest level.	Anton Khirnov	2019-01-26
\|
*	ell_relax -> ell_grid_solve	Anton Khirnov	2019-01-26
	Generalize the API to allow for multiple solver types. This is done in preparation for the exact linear system inversion solver.
