d801ebdd41 Now parameters and vertexbuffers (fields) can be declared with the DSL only. TODO: translation from the DSL header to C 2019-08-19 17:35:03 +03:00
jpekkila
bcdd827a4f Added a proper declarations for all user-specified uniform. Note: built-in uniforms are not correctly translated into CUDA 2019-08-19 17:05:56 +03:00
jpekkila
0208d55e4e Moved STENCIL_ORDER and NGHOST out of user-defined parameter as these are actually internal defines used to configure the built-in functions. Additionally, renamed all explicitly declared uniforms from dsx -> AC_dsx in the DSL in preparation for having clear connection between DSL uniforms and the library parameter handles created by the user (AcRealParam etc) 2019-08-19 16:40:47 +03:00

787363226b Added functions for loading int, int3, scalar and vector constants to the device layer (acDeviceLoad...Constant) 2019-08-19 15:28:16 +03:00

41805dcb68 Added some error checking for the case where user supplies an incomplete meshinfo to acDeviceLoadMeshInfo 2019-08-19 15:17:51 +03:00
jpekkila
598799d7c3 Added a new function to the device interface: acDeviceLoadMeshInfo 2019-08-19 15:14:00 +03:00

e89897985e Battled with math.h and cmath. We probably should move from C standard libraries to C++ ones internally (in places which are not visible via the interface) 2019-08-19 14:02:30 +03:00

36fea70560 Moved basic built-in functions for vector operations to math_utils.h from integration.cuh so that they are shared with the CPU and GPU 2019-08-15 11:04:22 +03:00

d5b2e5bb42 Added placeholders for new built-in variables in the DSL. Also overloads to DCONST_INT etc. Naming still pending and old DCONST_REAL etc calls still work. 2019-08-12 14:05:35 +03:00

b53cabbc44 Made the DSL syntax less confusing: Input and output arrays are now ScalarField and VectorFields instead of scalars and vectors. C++ initializers are now also possible, removing the need to declare Fields as int or int3 which was very confusing, like "what, you assing an int value to a real, what the &^%@?" 2019-08-08 21:07:36 +03:00

5f4246fb42 Standalone now uses O2 optimization level instead of O3. Also removed -march=native since this causes issues if the program is compiled on a different architecture than it is run on. Since we do not do heavy arithmetic on the host side and the host code is not performance-critical part of the code, -march-native is not very useful anyways 2019-08-06 14:46:13 +03:00

f3de2fa03c Made globalVertexIdx available during preprocessing. NOTE: potentially dangerous. globalVertexIdx should never be used for reading data from the vertex buffers. 2019-08-05 15:03:02 +03:00

6dfd03664d Still does not work. I'm starting to think that instead of this one huge revision, we should modify the existing interface step-by-step. 2019-08-02 15:31:24 +03:00

567ad61465 Multinode MPI implementation should be done later in its own branch. The focus of this branch is to revise the node and device layers. Commented out references to the Grid layer. 2019-08-02 13:54:54 +03:00
