| | ||||
* | 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. | |||
* | 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. | |||

| | | | | | Do nb_relax_post steps in the post-correct relaxation phase, not nb_relax_pre. | |||

| | ||||
* | 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. | |||
* | log: allow specifying a NULL callback to disable logging | Anton Khirnov | 2019-01-16 | |
| | ||||
* | 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. | |||
* | ell_relax: compute the residual norm in residual_calc() | Anton Khirnov | 2019-01-13 | |
| | | | | It is cheap and avoids an extra step in mg2d. | |||
* | ell_relax: do not calculate the residual at the fixed-val boundaries | Anton Khirnov | 2019-01-13 | |
| | | | | | Keep it at zero there to begin with, rather than enforce this later. This will be useful in the following commits. | |||
* | residual_calc.asm: fix partial stores | Anton Khirnov | 2019-01-13 | |
| | | | | .store1 and .store3 were switched | |||
* | residual_calc.asm: calculate x*=16 by x*=8; x+=x | Anton Khirnov | 2019-01-13 | |
| | | | | Frees up one mm register for future use. | |||

| | ||||
* | residual_calc.asm: implement writing partial blocks | Anton Khirnov | 2019-01-10 | |

| | ||||
* | residual_calc.asm: reduce the use of magic constants | Anton Khirnov | 2019-01-10 | |
| | ||||
* | residual_calc.asm: reduce register use in the s1 variant | Anton Khirnov | 2019-01-10 | |
| | | | | | Make it similar to the s2 version, which should make it easier to templatize the code in the future. | |||
