e4b981fc62 Removed the O2 flag since cmake still defines the O3 flag in CMAKE_CXX_FLAGS_RELEASE and it's confusing which one gcc chooses if both O3 and O2 are passed during compilation. If the issue was the march=native flag then this should also work on Tiara 2019-08-06 14:59:41 +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

fa6e1116cb The interface revision now actually works. The issue was incorrect order of src and dst indices when storing the mesh. 2019-08-05 17:26:05 +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

15ad7182db Added sum reduction. NOTE: Scalar sum does not pass the automated test but vector sum does. I couldn't see anything wrong with the code itself and I strongly suspect that the failures are caused by loss of precision due to summing a huge amount of numbers of different magnitudes. However I'm not yet completely sure. Something like the Kahan summation algorithm might be useful if the errors are really caused by fp arithmetic. 2019-07-31 17:07:03 +08:00

a3359b0d04 CONFIG_PATH is now supplied by ac_mkbuilddir. While using would be a bit more idiomatic, ASTAROTH_CONF_PATH is probably safer since ac_mkbuilddir.sh does the copying and knows for sure what the correct path is. 2019-07-29 15:55:27 +03:00

d1ca196ccd Added declaration of constants for sink particle. Still in the process of understanding how values are passed, but I've realized how physical equations are defined in stencil_process.sps and in principle I can replicate that for sink particle(which will mostly be gravity). 2019-07-29 13:18:24 +08:00

9d625688ac Apparently my edit this time was unsuccessful, tons of error messeages showed up when I ran "make -j" command in working directory. However this commit is mainly for education purposes, it's so that Miikka (main) and others can see what I changed easily and can use as teaching reference. 2019-07-26 16:22:04 +08:00

be44354b33 Astaroth does not require any additional libraries to be included, which is good. Previously required CUDA and C/C++ math libraries. 2019-07-23 21:03:42 +03:00
