	Commit message (Collapse)	Author	Age
*	mg2d: add MG2DContext.adaptive_step	Anton Khirnov	2024-04-16
\| \| \| \|	Unused, for API compatibility with the adaptive step branch.
*	mg2d: export the residual norm to the caller	Anton Khirnov	2020-01-20
\|
*	mg2d: add a designated error code for reaching maxiter	Anton Khirnov	2020-01-20
\| \| \| \| \|	Allows to reliably distinguish it from other error cases. Also specify that the values of u are defined for this error code.
*	mg2d: make init_guess() MPI-aware	Anton Khirnov	2019-06-29
\| \| \| \|	API and ABI break.
*	mg2d: add API for specifying singular diff coeffs at the boundaries	Anton Khirnov	2019-06-13
\| \| \| \|	API and ABI break.
*	mg2d: export the local component extents in public API	Anton Khirnov	2019-06-02
\|
*	mg2d: add support for MPI-based multi-component solves	Anton Khirnov	2019-05-23
\| \| \| \| \|	For the moment, only the finest component is distributed, any coarser levels are gathered to rank 0. That should change in the future.
*	mg2d: add API for interpolating an initial guess from a provided grid	Anton Khirnov	2019-04-02
\|
*	mg2d: make the refinement depth/exact solve size configurable	Anton Khirnov	2019-03-11
\| \| \| \|	API bump
*	mg2d: factor out the boundary condition-related API	Anton Khirnov	2019-01-25
\|
*	mg2d: split the constant definitions into their own header	Anton Khirnov	2019-01-25
\| \| \| \|	This will allow sharing them with ell_relax.
*	mg2d: failer earlier when relaxation does not converge	Anton Khirnov	2019-01-21
\|
*	mg2d: add a context variable to control the log level	Anton Khirnov	2019-01-16
\| \| \| \| \| \|	Simpler to use than overriding the log callback. API bump.
*	mg2d: add a function for getting maximum supported fd_stencil	Anton Khirnov	2019-01-16
\| \| \| \| \| \| \|	This is needed for the caller to know the number of boundary zones that can be filled. API bump.
*	mg2d: make the cfl factor runtime-configurable	Anton Khirnov	2019-01-13
\|
*	Add threading support through libthreadpool.	Anton Khirnov	2018-12-27
\|
*	mg2d: define log levels	Anton Khirnov	2018-12-06
\|
*	Finish support for 4th order accuracy.	Anton Khirnov	2018-11-28
\| \| \| \|	ABI and API break.
*	Add a function to measure timings for benchmarking.	Anton Khirnov	2018-09-26
\|
*	Better names for the boundary locations.	Anton Khirnov	2018-08-02
\|
*	Add support for non-power-of-2 sized grids.	Anton Khirnov	2018-08-01
\|
*	Implement the multigrid scheme.	Anton Khirnov	2018-08-01
