[mpich2-dev] Is there any most basic send and receive functions inMPICH2?

[Rajeev Thakur]

Dear Xiaojun,
                        At what level do you plan to implement the
encryption? Initially, you could try to add encryption just for the two main
sends MPI_Send and MPI_Isend. They are implemented in
src/mpid/ch3/mpid_send.c and src/mpid/ch3/mpid_isend.c.

Hi, there,
I am trying to add encryption algorithms in MPICH2. So I need to find the
most basic sending and receiving functions in MPICH2. 
However, it seems that all different sending functions (Bsend, Isend, send)
call their own sending routines.
I was wondering that does an atomic sending (and receiving) operation exist
in MPICH2? If it does, where is it?

Thanks a lot. 
Have a great weekend,
