CUDA library for calculating beta vectors for multiplane lensing situations using multiple Plummer lenses. This is in development and many problems may occur. This has only been tested on linux (Arch Linux and CentOS).
Build requirements:
g++
cmake
cuda
gtest (optional)
By default this library will be build for sm sm_30. If you have a
newer card, you might get better results specifying a newer arch.
cmake CMakeLists.txt
make
To specify another arch, set SM_VER for cmake
cmake CMakeLists.txt -DSM_VER=sm_61
To build for usage on the VSC (Tesla p100) use:
cmake CMakeLists.txt -DVSC_BUILD=1
cmake CMakeLists.txt -DCMAKE_BUILD_TYPE=DEBUG
make
To build the unit tests you need to have GTest installed. If GTest is not found, the tests are skipped. The tests are only build in the DEBUG configuration.
./bin/unit_tests
./bin/cu_unit_tests
For Arch Linux a PKGBUILD can be found here
By default it installs the library to /usr/local/ on linux, on
archlinux this doesn't work out of the box (/usr/local/lib is not in
the ld path, depends on distro).
sudo make install
For archlinux and others you can specify DESTDIR.
sudo make DESTDIR="$pkgdir/" install
Alternatively add to the ld config if you encounter an error like this:
./example: error while loading shared libraries: liblens_common.so: cannot open shared object file: No such file or directory
By executing the following commands.
sudo sh -c 'echo "/usr/local/lib" >> /etc/ld.so.conf.d/multiplanecuda.conf'
sudo ldconfig
To use this library see example/example.cpp.
You can run Doxygen to generate the documentation. Some
documentation is still missing or outdated.
For the example there is a notebook that generates some test parameters. A file generated by this notebook can be used as a test file.
This project was made for my bachelor's thesis for the School for Information Technology from the tUL.
