ae0d4de23c The root host mesh is no longer allocated during benchmarking as this caused out-of-memory errors in weak scaling tests 2020-10-29 16:33:41 +02:00

d966afe830 Added VERBOSE CMake option and made various prints optional to clean the output. VERBOSE is by off by default, pass cmake -DVERBOSE=ON to re-enable various non-critical warning and status prints (important warnings are still visible regardless of the flag). 2020-08-21 21:19:42 +03:00

f7d8de75d2 Reduction test pipeline added to mpitest, Error struct changed: new label field 
- CHANGED: Error struct has a new label field for labeling an error
   - The label is what is printed to screen
   - vtxbuf name lookup moved out of printErrorToScreen/print_error_to_screen
 - NEW: acScalReductionTestCase and acVecReductionTestCase
   - Define new test cases by adding them to a list in samples/mpitest/main.cc:main
 - Minor style change in verification.c to make all Verification functions similar
   and fit one screen

17c935ce19 Added padding to param name buffers to make them have NUM_*_PARAMS+1 elements. This should satisfy some strict compilation checks. 2020-01-28 18:53:09 +02:00

0ccd4e3dbc Major improvement: uniforms can now be set to default values. The syntax is the same as for setting any other values, f.ex. 'uniform Scalar a = 1; uniform Scalar b = 0.5 * a;'. Undefined uniforms are still allowed, but in this case the user should load a proper value into it during runtime. Default uniform values can be overwritten by calling any of the uniform loader funcions (like acDeviceLoadScalarUniform). Improved also error checking. Now there are explicit warnings if the user tries to load an invalid value into a device constant. 2020-01-28 18:17:31 +02:00

7215e842fc Simplified the include directory. Everything is now in only two headers: astaroth.h and astaroth_utils.h. Removed old and unused stuff. user.h is unused in standalone but might be used with Pencil Code, so left that intact. 2020-01-23 19:59:44 +02:00

d51d48071f Updated documentation and made it work with Doxygen. Now the doc/doxygen/index.html generated with it looks quite good and contains lots of useful and up-to-date information about Astaroth 2020-01-13 21:11:04 +02:00

794e4393c3 Added a new function for the legacy Astaroth layer: acGetNode(). This functions returns a Node, which can be used to access acNode layer functions 2020-01-13 11:33:15 +02:00

f14e35620c Now nvcc is used to compile kernels only. All host code, incl. device.cc, MPI communication and others are now compiled with the host C++ compiler. This should work around an nvcc/MPI bug on Puhti. 2019-12-03 15:12:17 +02:00

f1e988ba6a Added stuff for the device layer for testing GPU-GPU MPI. This is a quick and dirty solution which is primarily meant for benchmarking/verification. Figuring out what the MPI interface should look like is more challenging and is not the priority right now 2019-10-17 14:40:53 +03:00

0865f0499b Various improvements to the MPI-GPU implementation, but linking MPI libraries with both the host C-project and the core library seems to be a major pain. Currently the communication is done via gpu->cpu->cpu->gpu. 2019-10-15 19:32:16 +03:00

aa6c2b23d9 Built-in parameters are now added during compilation instead of defining them in CUDA sources. IMPORTANT: DCONST macro should no longer be used when accessing built-in variables. Now all uniforms are consistently accessed with the handle only 2019-10-07 17:39:27 +03:00
