The FCC-ee software tutorial for the FCC-ee BNL workshop (April 24–26, 2023) requires a Linux computer with the mounted CVMFS (/cvmfs/sw.hsf.org/key4hep/). This key4hep directory includes key4hep software, C++ compiles and other external C++ libraries. If you do not plan to install the CVMFS pointed to the CERN libraries, one can use the following interactive nodes:

• lxplus.cern.ch - for people associated with CERN and having the CERN computer accounts.
• Members from the ATLAS/CMS and other collaborations can use their Tier3 computers which have cvmfs
• BNL participants can use …
• OSG interactive nodes can be used by all other participants who cannot use the options above. These resources are available for the USA participants associated with USA institutes.

How to get the OSG account: : If you are already associated with a USA institution, use this https://www.osgconnect.net/ link to sign-up. During the sign-up, request the project osg.FutureColliders (Sergei Chekanov is the project PI). Then you will be explained how to obtain the account. This project typically uses the “login05.osgconnect.net” interactive node. This note links the /cvmfs/sw.hsf.org/key4hep/ which will be needed for this tutorial.
