memory efficient parallel compting

[ArthurPERE]

Hello,

I have a question about the memory of the parallel. I am on linux so the parameter for the parallelism is MulticoreParam.

Each time a session spawn, the whole memory is copied to this session (at least that what I understand). But I don't want that the whole memory of the session to be copied. Is there a trick to be used to not do that, for exemple spawning a whole new session (even if it means putting aside a little performance), detached from the inital session

Thank you for your answer
