37 37  Via choosing a different lab execution site it is be possible to choose a specific site, if there are specific needs for the created Jupyter virtual machine for a given task (e.g. a large memory requirement). Currently all the examples do not need any site specific features, so you can select in principle any site. BUT (as of end of August 21) there is a sporadic problem with the NMPI communication, if running at Jülich. Thus for now, please use CSCS as the primary execution site.
