Hi, In open MPI, where are the binaries stored. Let's say I have a program P that adds the numbers in an array of length 10 I want to distribute the execution between 2 computers A and B A adds from array[0] to array[4] B adds from array[5] to array[9]
I understand that I have to tell mpi that machines A and B exist and that I want the processes to be exected as required. No problem with this, my confusion is in the implementation. lets say I am running the adding program P from machine C. When I execute the P program, how do computers A and B know what binary to execute? My binaries are in copmuter C! Does MPI copy the binaries to machines A and B from C? and then executes the program? How is the program P loaded to memory in A and B, is P stored on disk in A and B? Do I have to copy the P binaries in A and B prior to executing the program? When the program P has finished execution , what happens to the binaries. I have not found anything on the web to answer my question Thank you
