# C source skeleton
|
||||
|
||||
## Build
|
||||
|
||||
1. Configure the toolchain and additional options in `config.mk`:
|
||||
```
|
||||
# Supported: GCC, CLANG, ICC
|
||||
TAG ?= GCC
|
||||
ENABLE_OPENMP ?= false
|
||||
|
||||
OPTIONS += -DARRAY_ALIGNMENT=64
|
||||
#OPTIONS += -DVERBOSE
|
||||
#OPTIONS += -DVERBOSE_AFFINITY
|
||||
#OPTIONS += -DVERBOSE_DATASIZE
|
||||
#OPTIONS += -DVERBOSE_TIMER
|
||||
```
|
||||
|
||||
The verbosity options enable detailed output about solver, affinity settings, allocation sizes and timer resolution.
|
||||
For debugging you may want to set the VERBOSE option:
|
||||
```
|
||||
# Supported: GCC, CLANG, ICC
|
||||
TAG ?= GCC
|
||||
ENABLE_OPENMP ?= false
|
||||
|
||||
OPTIONS += -DARRAY_ALIGNMENT=64
|
||||
OPTIONS += -DVERBOSE
|
||||
#OPTIONS += -DVERBOSE_AFFINITY
|
||||
#OPTIONS += -DVERBOSE_DATASIZE
|
||||
#OPTIONS += -DVERBOSE_TIMER
|
||||
`
|
||||
|
||||
2. Build with:
|
||||
```
|
||||
make
|
||||
```
|
||||
|
||||
You can build multiple toolchains in the same directory, but notice that the Makefile is only acting on the one currently set.
|
||||
Intermediate build results are located in the `<TOOLCHAIN>` directory.
|
||||
|
||||
To output the executed commands use:
|
||||
```
|
||||
make Q=
|
||||
```
|
||||
|
||||
3. Clean up with:
|
||||
```
|
||||
make clean
|
||||
```
|
||||
to clean intermediate build results.
|
||||
|
||||
```
|
||||
make distclean
|
||||
```
|
||||
to clean intermediate build results and binary.
|
||||
|
||||
4. (Optional) Generate assembler:
|
||||
```
|
||||
make asm
|
||||
```
|
||||
The assembler files will also be located in the `<TOOLCHAIN>` directory.
|
||||
|
||||
## Usage
|
||||
|
||||
You have to provide a parameter file describing the problem you want to solve:
|
||||
```
|
||||
./exe-CLANG dcavity.par
|
||||
```
|
||||
|
||||
Examples are given in in dcavity (a lid driven cavity test case) and canal (simulating a empty canal).
|
||||
|
||||
You can plot the resulting velocity and pressure fields using gnuplot:
|
||||
```
|
||||
gnuplot vector.plot
|
||||
```
|
||||
and for the pressure:
|
||||
```
|
||||
gnuplot surface.plot
|
||||
```
