Researchers can make use of the same software as on their own infrastructure. ARC middleware enables users to use any software on the clusters. Environment modules are preinstalled. Clusters also offer support for running container images, which can contain diverse operating systems, applications and libraries.
Larger VOs use make use of CVMFS or containers to run their experiments. They also provide a list of required packages that need to be installed on the worker nodes.
If researches use software that runs on Windows operating system, they can only run their workflow in the virtualized environments in the cloud.
Existing software and tools
Some disciplines have developed their own software, adjusting the existing packages. The EGI register of applications and virtual appliances is available in the EGI application database.
