GGEMS

Description

GGEMS is an advanced Monte Carlo simulation platform using CPU and GPU architecture targeting medical applications (imaging and particle therapy). This code is based on the well-validated Geant4 physics model and capable to be executed in both CPU and GPU devices using the OpenCL library.

Features:

Photon particle tracking
Multithreaded CPU (Intel, AMD not tested)
GPU (NVIDIA, Intel, AMD not tested)
Multi devices (GPUs+CPU) approach
Single or double float precision for dosimetry application
External X-ray source
Navigation in simple box volume or voxelized volume
Flat or curved detector for CBCT/CT application
OpenGL visualization
Dosimetry application (photon)
TLE (Track Length Estimator) method for dosimetry

Requirements

GGEMS is a multiplatform application using OpenCL.

OpenCL v1.2 or more must be installed on your system.

Supported operating system:

Windows
Linux

Tested compilers:

gcc 7/8/9 on Linux
clang from version 9 to 13 on Linux and Windows
Visual C++ 2022 on Windows

Installation

To install GGEMS, please follow the procedure here: https://doc.ggems.fr/v1.2/building_and_installing.html

GGEMS using Docker for Linux users

A docker image for GGEMS version 1.2 is available here:

foo@bar~: docker pull ggems/ggems:v1.2

Important

To use the docker image on your linux machine, the nvidia driver must be installed as well as the 'nvidia-container' library. To install 'nvidia-container' run the following commands:

foo@bar~: sudo apt install curl
foo@bar~: curl -s -L https://nvidia.github.io/nvidia-container-runtime/gpgkey | sudo apt-key add -
foo@bar~: distribution=$(. /etc/os-release;echo $ID$VERSION_ID)
foo@bar~: curl -s -L https://nvidia.github.io/nvidia-container-runtime/$distribution/nvidia-container-runtime.list | sudo tee /etc/apt/sources.list.d/nvidia-container-runtime.list
foo@bar~: sudo apt update
foo@bar~: sudo apt install nvidia-container-runtime

To test the docker image, run this command:

foo@bar~: docker run -it --rm --gpus all ggems/ggems:v1.2 nvidia-smi
