| * | meson.build: add a trailing slash to asm include path | Anton Khirnov | 2020-07-13 |
| | | | | | Required by earlier nasm versions. | ||
| * | Track forgotten timer files. | Anton Khirnov | 2020-07-13 |
| | | |||
| * | mg2d: avoid leaks in mg_dh_init() | Anton Khirnov | 2020-07-12 |
| | | |||
| * | mg2d: add logging to some error paths | Anton Khirnov | 2020-07-11 |
| | | |||
| * | Switch to external ndarray library. | Anton Khirnov | 2020-06-25 |
| | | |||
| * | bicgstab: drop unused label | Anton Khirnov | 2020-01-26 |
| | | |||
| * | common: print the source location in mg2di_assert() | Anton Khirnov | 2020-01-26 |
| | | |||
| * | mg2d: create a per-level logging context | Anton Khirnov | 2020-01-26 |
| | | |||
| * | 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. | ||
| * | transfer: slightly relax the domain overlap check | Anton Khirnov | 2020-01-20 |
| | | | | | | Allow the destination domain to be outside the source by a small margin (1e-12). | ||
| * | common: do not interpret printf sequences in mg2di_assert() | Anton Khirnov | 2019-07-10 |
| | | |||
| * | mg2d: calculate the cfl from continuous diff coeffs | Anton Khirnov | 2019-07-06 |
| | | |||
| * | mg2d: reduce restriction order to 1 | Anton Khirnov | 2019-06-29 |
| | | | | | This seems to work more reliably. | ||
| * | egs: reduce the max number of BiCGSTAB iterations to 4 | Anton Khirnov | 2019-06-29 |
| | | | | | | Since we typically do many multigrid iterations per step, being more aggressive about a full inverse gives better performance. | ||
| * | egs: sync the residual maximum across components. | Anton Khirnov | 2019-06-29 |
| | | |||
| * | transfer: implement and use 1D interpolation | Anton Khirnov | 2019-06-29 |
| | | | | | Stop abusing "2D of y size 1" for this. | ||
| * | mg2d: make init_guess() MPI-aware | Anton Khirnov | 2019-06-29 |
| | | | | | API and ABI break. | ||
| * | implement several relax steps per sync | Anton Khirnov | 2019-06-29 |
| | | |||
| * | egs: make array allocation more readable | Anton Khirnov | 2019-06-29 |
| | | |||
| * | egs: allocate mpi sync parameters only after we know the fd stencil | Anton Khirnov | 2019-06-18 |
| | | | | | | Also, forbid it to change after first init. That is not ever used and allowing it unnecessarily complicates the logic. | ||
| * | egs: skip boundary corners for inter-component boundaries | Anton Khirnov | 2019-06-18 |
| | | |||
| * | egs: simplify reflection boundary handling | Anton Khirnov | 2019-06-14 |
| | | |||
| * | rescalc: improve reflection boundary conditions | Anton Khirnov | 2019-06-14 |
| | | | | | | Make parameter names more clear/consistent, document them, implement missing 1U boundary. | ||
| * | egs: constify a function argument | Anton Khirnov | 2019-06-14 |
| | | |||
| * | mg2d: add API for specifying singular diff coeffs at the boundaries | Anton Khirnov | 2019-06-13 |
| | | | | | API and ABI break. | ||
| * | mg2d: relax condition on divergence | Anton Khirnov | 2019-06-13 |
| | | |||
| * | ndarray: fix handling SLICE_NULL | Anton Khirnov | 2019-06-13 |
| | | |||
| * | mg2d: implement multicomponent solves for coarser levels | Anton Khirnov | 2019-06-13 |
| | | |||
| * | mg2d: do not pass NULL as a dummy MPI datatype | Anton Khirnov | 2019-06-04 |
| | | | | | Use MPI_DATATYPE_NULL. | ||
| * | mg2d: use the all-comp global residual norm for divergence testing | Anton Khirnov | 2019-06-04 |
| | | | | | | Residual may grow dramatically in certain components while globally decreasing. | ||
| * | mg2d: export the local component extents in public API | Anton Khirnov | 2019-06-02 |
| | | |||
| * | egs: handle falloff boundaries properly with multiple components | 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. | ||
| * | egs: add support for MPI-based multi-component solves | Anton Khirnov | 2019-05-23 |
| | | |||
| * | mg2d_test: scale the tolerance with step size | Anton Khirnov | 2019-05-23 |
| | | |||
| * | transfer: allow optional extrapolation | Anton Khirnov | 2019-05-23 |
| | | |||
| * | Make the ghost points explicit in prolongation | Anton Khirnov | 2019-05-21 |
| | | |||
| * | transfer: implement fw4 | Anton Khirnov | 2019-05-17 |
| | | |||
| * | transfer: allow grids that do not start at coordinate zero | Anton Khirnov | 2019-05-17 |
