Installation

Libraries

2 libraries are required: GSL and boost:serialization. GSL can be omitted if you don't need to generate random walk dataset on your own. Just remove related line in CMakeLists.txt, with the file name "src/Expr/RandDataGenerator.cpp" "include/Expr/RandDataGenerator.h" in COMMAND add_executable (10th line in CMakeLists.txt) boost:serialization is used to serialize the memory index structure, so it is necessary for NOW, though an ad-hoc serialization version might be developed in the future.

Build

Here is a Cmake project. All the information about compiling is in CMakeList.txt. We test this project in Cmake 3.20 with C++ language standard 23, however, we SUBJECTIVELY think it can run on relatively lower versions.

If you can use IDE like Clion, just open this project use that and build it automatically and then run it.

Else, please refer to following instructions.

1. create a "build" directory under the project

2. cd build

3. cmake ..

4. make

5. cd .. && ./bin/FADAS

Run

All the configuration is written on the config.ini, including the information about dataset. To finish your task, please READ and UPDATE config.ini IN DETAIL.
