 JURON und JURECA both share a common file system (*GPFS*). For working on both machines simultaneously, a dedicated folder for a build on each machine might be helpful.
 
 JURECA offers `$HOME` and `$WORK` for long-term and short-term (but somewhat faster) storage of data. JURON offers both locations as well, but without any difference in connection speed.
