#488: Reduce space taken by Formaline tarballs --------------------------+------------------------------------------------- Reporter: hinder | Owner: Type: enhancement | Status: review Priority: minor | Milestone: Component: Cactus | Version: Resolution: | Keywords: Formaline --------------------------+-------------------------------------------------
Comment (by eschnett):
Formaline already uses hardlinks e.g. for executables and for checkpoint files. This just adds another use case. Such space optimizations were present from the beginning, since they were very important -- otherwise it would be too expensive to keep simulations and restarts independent.
Tarballs will be larger for production runs involving additional, non-ET thorns. People will also want to handle several (many) simulations, and the sizes add up.
Simfactory assumes that, once a restart has finished (and has been cleaned up), its contents are not modified any more. It is okay to add more content, but it is not okay to modify or remove files.
