Simulator for the Linear Collider (SLIC)

The SLIC simulator is a Geant4 package that uses LCDD as its geometry input.

To see the available command line options, execute the following from the shell:

slic --help 

To print the version of the application, execute the following:

slic --version 

The primary source of documentation for SLIC is its Confluence Wiki page.

Any questions can be directed to Jeremy McCormick or Norman Graf.

Installation

SLIC is a C++ application that is built using the standard GCC compiler toolchain and the CMake build generation system.

Required Tools

• Recent gcc compiler toolchain (tested with GCC 7 on CentOS7)
  • You cannot use the default gcc on RHE6 or a similarly old distribution, so you would need to install one yourself or use a dev toolset.
  • The build is not compatible with gcc 4.8.5 now due to Geant4 updates.
• CMake 3.8 or greater due to requirements of the Geant4 build system (tested with 3.17)

Build Instructions

Start by cloning the project to a local directory.

mkdir /scratch && cd /scratch
git clone https://github.com/slaclab/slic

Create the build directory within your slic project directory:

mkdir build && build

The SLIC build system is able to download and install all dependencies for the project if they are not found on your system. This requires a multi-step build for the dependencies to first be downloaded and installed before SLIC itself is built.

From the build dir created above execute the following:

cmake ..

You should see a number of messages printed that indicate dependencies were not found and will be built.

There are a few cmake options that can be used for configuring SLIC:

Variable	Default Value	Description	Notes
WITH_GEANT4_UIVIS	NO	Enable Geant4 visualization and UI	Requires X11 and Qt
WITH_GEANT4_VERSION	10.6.1	Geant4 release tag to use	master is not allowed
CMAKE_INSTALL_PREFIX	${CMAKE_BUILD_DIR}/install	Installation prefix for slic and deps

Here is an example of all these options being used together:

cmake -DWITH_GEANT4_UIVIS=ON -DWITH_GEANT4_VERSION=10.6.1 -DCMAKE_INSTALL_PREFIX=/work

These options should be passed the first time you execute the cmake command when building the application.

Now to the dependencies and SLIC, execute the following:

make

Now, you should be ready to install slic if the above completed without errors:

make install
