As no copy is involved, performance should not be altered (but memory occupation will be higher). This solution actually works really good for a good number of MPI -application. Its main limitation is that if the application loads dynamic +applications. Its main limitation is that if the application loads dynamic libraries, their global variables won't be privatized. This can be avoided by linking statically with these libraries (but NOT with libsimgrid, as we need SimGrid's own global varibles).
