Hi, In http://www.mpich.org/static/docs/v3.1/www3/MPI_Win_attach.html, for MPI 3, The API MPI_Win_attach is supported :
int MPI_Win_attach(MPI_Win win, void *base, MPI_Aint size) It allows multiple (but non-overlapping) memory regions to be attached to the same window, after the window is created. Therefore, I should be able to have multiple such “attach” calls for the same window, with different “base” address to be specified in each attach call. If that is the case, when I issue the MPI_Get, how can I specify which “base address” on the window is what I need to fetch the data? As MPI_get has the window handle to be one of the input parameters, but not“base address”. The base address should be resolved by the target process from the registered window handle. So my question is: how can MPI_Get handle the situation where multiple memory regions are attached to the same window? Thank you! -- Lokah samasta sukhinobhavanthu Thanks, Madhurima
