Hi!!!! I am Pooja.I am working with chaitali on this project. We want to shift BTL transport to the higher levels. So we are configuring MPi using all development header file . This will enable us to call btl /Bml functions directly at the higher level. So we will send a normal file across the network calling BTL btl_send function directly . Another option is not to use BTL_send but to send using TCp socket (writing our own tcp_send code). SO we just want to ask whether that is possible and if yes what we are thinking ahead is right??
