  • 01437411b6 Comment jpekkila 2019-07-04 16:39:20 +03:00
  • 91f119e8dd Deprecated the old implementation of acIntegrateStep. acIntegrateStep now calls acIntegrateStepWithOffset instead of device.cuh functions. jpekkila 2019-07-04 16:37:55 +03:00
  • 5049dadc1c Implemented acIntegrateStepWithOffset jpekkila 2019-07-04 16:31:16 +03:00
  • a53e0a170d Overloaded max/min for int3 and removed old comments jpekkila 2019-07-04 16:24:08 +03:00
  • e1d545b0eb Code readability and cleanup (remembered that int3 has + and - operators defined in math_utils.h) jpekkila 2019-07-04 16:16:49 +03:00
  • 30254d9abb Removed a redundant and old gridIdxx function which I though I already removed a long time ago. jpekkila 2019-07-04 16:10:29 +03:00
  • b3a0b10a86 Removed old comments jpekkila 2019-07-04 16:02:13 +03:00
  • 24f49ce461 Host code now compiled according to the C++11 standard. The device code has used C++11 for a while now and it's good to use a single standard consistently throughout the project. Old Intel compilers (~14.0) do not seem to support C++11 but the code should still compile since the flag is ignored in that case. jpekkila 2019-07-04 16:01:02 +03:00
  • 0884c4bf38 Moved the definition of acForcingVec to host_forcing.cc since it depends on user parameters that may not be defined in all projects jpekkila 2019-07-04 15:28:18 +03:00
  • 698d04c57d Removed a deprecated code block jpekkila 2019-07-04 15:08:42 +03:00
  • 317df4c025 Re-enabled the check for implicit float-double-float conversions with gcc jpekkila 2019-07-04 13:45:09 +03:00

  • 2c4d129216 -Werror-all disabled from Intel compiler flags Miikka Vaisala 2019-07-04 11:25:04 +08:00
  • 0a030742f9 Added support for calling compile_acc.sh with custom headers jpekkila 2019-07-03 19:06:39 +03:00
  • 7abb959828 Overhaul to the user-defined parameters done: All logical switches, parameters and vertex buffer handles are now defined in a single header file (the default location is acc/mhd_solver/stencil_defines.h). This header is used when preprocessing the DSL sources and is linked to the include/ directory when calling scripts/compile_acc.sh. astaroth.h is now used for configuring internal stuff only and should not be modified by users jpekkila 2019-07-03 19:01:16 +03:00
  • 6907d74ea3 Suppressed an unused variable warning for globalVertexIdx jpekkila 2019-07-03 18:46:17 +03:00
  • 7d6255ba14 Suppressed unused variable warnings in kernels.cuh jpekkila 2019-07-03 18:12:48 +03:00
  • 556cb77dbb Removed weird unused functions from model_rk3.cc. I have no idea where these came from. Probably remnants from the time I was pulling all-nighters to finish my thesis. jpekkila 2019-07-03 18:06:40 +03:00
  • b4eea4b6b6 Changed #if 0 to #if LFORCING instead to get the code to compile if forcing is used (even though autotesting does not support it yet). Also more autoformatting. Maybe I should disable it or then everyone should start using it to avoid cluttering commits with these superficial changes jpekkila 2019-07-03 17:49:34 +03:00
  • 609cfaea14 Commenting the unused variables in simulation.cc a few commits back was the wrong move since the variables are needed if LFORCING it set. jpekkila 2019-07-03 17:46:50 +03:00
  • acc53e1c2b Merged master to acc_parameter_overhaul jpekkila 2019-07-03 17:37:37 +03:00
  • e8a5579b50 Made the gcc error flags more lenient temporarily since there are so many float-double-float conversion errors in host_forcing.cc jpekkila 2019-07-03 17:25:26 +03:00
  • 81a09501b8 Removed deprecated LNT0 and LNRHO0 defines, now the actual configuration parameters are used (AC_lnrho0 and AC_lnT0). Also accidental autoformatting again, there seems to be stray spaces before linebreaks in some files which get automatically removed by my text editor jpekkila 2019-07-03 17:23:37 +03:00
  • 8ed947ce98 Removed deprecated sinusoidal forcing from kernels.cuh jpekkila 2019-07-03 17:13:45 +03:00
  • d7228f0647 Added an explicit cast from double to AcReal to avoid a narrowing conversion error jpekkila 2019-07-03 17:11:26 +03:00
  • 919d446222 Commented out unused variables in simulation.cc jpekkila 2019-07-03 17:10:40 +03:00
  • d54ccc1da8 Deprecated a block of old code that was used a long time ago for testing forcing jpekkila 2019-07-03 17:10:01 +03:00
  • 945751e585 Autoformatted host_forcing.cc jpekkila 2019-07-03 17:06:57 +03:00
  • af3a1e211e Suppressed unused variable and function warnings in model_rk3.cc jpekkila 2019-07-03 17:03:26 +03:00

  • 08e9a32cb1 Added a comment about acForcingVec jpekkila 2019-07-03 16:37:16 +03:00
  • d4d2680f40 Added a new generic function to the interface (astaroth.h) for loading arbitrary device constants. Also (unintended) autoformatting. jpekkila 2019-07-03 16:19:25 +03:00
  • 32c8520543 Removed testfile.txt. Demonstration over. Miikka Vaisala 2019-07-03 17:37:27 +08:00
  • 46a2ef4847 Commit demonstration for student. Miikka Vaisala 2019-07-03 15:13:01 +08:00
  • 98713ff9d2 A possible bug note added. Will look into late. Miikka Vaisala 2019-07-03 14:49:10 +08:00
  • f0d2be831e host_forcing now committed. Sorry. Miikka Vaisala 2019-07-03 09:55:23 +08:00
  • 334ff868d9 Forcing disabled from autotest and from defaults. Miikka Vaisala 2019-07-02 18:46:04 +08:00
  • 4766441ffb Tryin to prepare autotest for forcing. Miikka Vaisala 2019-07-02 18:24:41 +08:00
  • 03689709df Merge branch 'master' into forcing Miikka Vaisala 2019-07-02 16:43:10 +08:00
  • d0eb308f17 Better interface to forcing. Miikka Vaisala 2019-07-02 16:35:14 +08:00
  • d9b07a59b5 Tested with hydro, hydro + magnetic, hydro + magnetic + entropy and hydro + magnetic + entropy + forcing. Autotests passed in all cases. jpekkila 2019-07-01 19:01:33 +03:00
  • 1e6740f999 Added the equations for hydro only for both CPU and GPU. NOTE: NOT RIGOROUSLY CHECKED FOR CORRECTNESS. I just took the equations used with entropy and removed the terms which included entropy and magnetic fields jpekkila 2019-07-01 18:56:13 +03:00
  • 75f74526f4 Fixed incorrect logic with ifdefs: LMAGNETIC etc are toggle switches and are always defined jpekkila 2019-07-01 18:43:04 +03:00
  • 21e9fc943b Removed all defines from the stencil assembly and processing files and moved them to the new stencil_defines header. There were spaces after some linebreaks which were removed when I autoformatted the code and that's why there seems to be more changes that there actually is. jpekkila 2019-07-01 18:40:13 +03:00
  • b8869bb848 Linked the defines used by the DSL and astaroth.h. Now f.ex. LENTROPY has to be set only once in acc/mhd_solver/stencil_defines.h and it is propagated throughout the whole project. The name for stencil_defines.h is not final and may change if I come up with a better name. In any case, there is now a standard header associated with each DSL solver where the user can set defines, and declare arrays (VTXBUF_LNRHO) and device constants (uniforms). jpekkila 2019-07-01 18:37:56 +03:00
  • 9a87053f26 README.md edited online with Bitbucket jpekkila 2019-07-01 14:08:59 +00:00

  • 11ceca4cb1 Second test commit (feature branches) jpekkila 2019-07-01 14:54:55 +03:00
  • 30b7cda35c Testing the git commands for creating feature branches and merging them back to master jpekkila 2019-07-01 14:42:36 +03:00
  • a3ca6cf132 Added skeletons for packing parts of the ghost zones into buffers to speed up data transfers jpekkila 2019-07-01 13:56:05 +03:00
  • d9be66f65f NOTE: Renamed LINDUCTION to LMAGNETIC throughout the project. jpekkila 2019-07-01 13:40:24 +03:00
  • 0600790f41 Corrected a bug in the timestep and some scaling problems. Miikka Vaisala 2019-07-01 14:19:56 +08:00
  • 9f0be0d9ff Solved the forcing function boundary problem. Miikka Vaisala 2019-07-01 11:06:42 +08:00
  • 0c63d55fd7 Worked around a compiler bug in CUDA 9.1, which caused an "Internal Compiler Error (codegen): "there was an error in verifying the lgenfe output!". Apparently the compiler got confused by overloaded is_valid() if the input parameter was not passed as a reference in both cases. jpekkila 2019-06-29 10:49:15 +03:00
  • f04ef8e64c Forcing function issue not yet fully resolved. Miikka Vaisala 2019-06-28 19:23:18 +08:00
  • 9b45716186 Modified user.h such that astaroth compiles with Pencil Code. Note that this is a temporary fix: we should ultimately set the default parameters for all the logical switches in astaroth.h and let the user redefine them at will, either with the DSL or with user.h jpekkila 2019-06-27 18:12:14 +03:00
  • b694702cf8 Removed an old comment jpekkila 2019-06-27 17:11:21 +03:00
  • 94a25383a9 Trying to calculate the forcing scaling. Miikka Vaisala 2019-06-27 19:20:18 +08:00
  • 30c21ff420 Formatting: defines stay indented if clang-format is turned off temporarily jpekkila 2019-06-27 13:31:50 +03:00
  • 8ca09668c1 Added an advance notice about LINDUCTION to be renamed to LMAGNETIC in the near future throughout the project. LMAGNETIC would be better name since he define is used to enable the magnetic field. jpekkila 2019-06-27 13:28:52 +03:00
  • fc96283c37 Reordered logical flags in a more logical order, density -> hydro -> induction -> entropy -> others jpekkila 2019-06-27 13:22:14 +03:00
  • 75fb756ad4 Autoformatted with clang-format. Clang-format does not support indented defines as far as I know, so this will have to do. The alternative would be not to use autoformatting at all (or some other tool). jpekkila 2019-06-27 13:16:41 +03:00
  • 9b2e9d376f helical_forcing_k_generator() added. Miikka Vaisala 2019-06-27 18:12:15 +08:00
