# MD-Bench
|
|
|
|
A simple, sequential C implementation of the [Mantevo miniMD](https://github.com/Mantevo/miniMD) benchmark in less than 1000 LOC.
|
|
|
|
## Build
|
|
|
|
1. Open `config.mk` and edit the `TAG` value according to the tool chain used. Currently supported is GCC, CLANG (LLVM), and ICC (Intel).
|
|
2. Change `DATA_LAYOUT` and `DATA_TYPE` if desired in config.mk.
|
|
3. Open and adapt the compiler flags in `<include_<TOOLCHAIN>.mk`, e.g. in `include_ICC.mk` for the Intel tool chain.
|
|
4. Build the binary calling `make`.
|
|
|
|
You can clean intermediate build results with `make clean`, and all build results with `make distclean`.
|
|
You have to call `make clean` before `make` if you changed the build settings.
|
|
|
|
## Configuration
|
|
|
|
Currently all settings apart from the options described below are hard-coded in `main.c`.
|
|
|
|
## Run the benchmark
|
|
|
|
Without any options 200 steps with system size 32x32x32 is used.
|
|
|
|
The default can be changed using the following options:
|
|
```
|
|
-n / --nsteps <int>: set number of timesteps for simulation
|
|
-nx/-ny/-nz <int>: set linear dimension of systembox in x/y/z direction
|
|
```
