Development Notes

• many changes happened in support_funcs.cpp, need to be carefull when check functions in UVZsolver.cpp since they call many kernels in support_funcs.cpp

Done:

• Get rid of global constant
• Load all inputs from files
• Tested Memcopy from host to device
• Rewrite makefile
• Check kernels without constants in support_funcs.cpp
• Test kernels without constants in UVZsolver_multithreads.cpp
• change sediment transport kernels to work with non_constant versions
• Put things to gether
• Call kernels one by one to check if things are in their right positions
• Test final result for hydraulic module
• test sediment transport functions
• test the program with sediment transport

Todo:

• Use new tridiag solver to test performance

Running Instruction:

1. Fill in correct coefficients for input mesh in Load_coeffs() function in loader.cpp files
2. Copy input files to Inputs/ directory with corresponding names:

• bandodosau.txt : depth map of to-be compute mesh data
• hsnhotroiA.txt: visco coefficient map
• hsnham.txt: roughness index map
• Fw_map.txt: Fw coefficient map
• FS_bientren.txt: FS boundary condition for upper boundary
• FS_bienduoi.txt: FS boundary condition for lower boundary
• FS_bientrai.txt: FS boundary condition for left side boundary
• FS_bienphai.txt: FS boundary condition for right side boundary
• bientren.txt: boundary condition for upper boundary
• bienduoi.txt: boundary condition for lower boundary
• bientrai.txt: boundary condition for left side boundary
• bienphai.txt: boundary condition for right side boundary
• boundary_type.txt: boundary type of each side (solid type or water type)

3. Run standardize_inp.py to transpose inputs into Python-style coordinates
4. run command: ~$ make to compile changes
5. input arguments in args.txt with following options:

• -f Directory that contains input files -h Number of running hour -m number of running mins -s number of running seconds -i time interval in which output is saved -b time, in second, at which Sediment transport is started to be computed

6. run command: $ ./rep `cat args.txt` to run rep file with the specified arguments in args.txt
