It seems to me that it would be easier to have a discussion if you quoted the questions and comments (from me) you're replying to. I notice that you seem to be posting using Google's interface. I'm not, so I don't really know what the options are, but if you can reply to one of your own posts, it seems like you should be able to reply to someone else's. > > Thanku, > > > > M D C > > Its not that i want quick response. Its just my bad i could not club my queries in a single question.sorry for that. But why would you want to ("club your queries" -- I'm guessing you mean "group them together"? not criticizing your English if it's not your first language, and probably not that important to be clear about this anyway)? > U r right in front of -np there should be no. of processes, in my case its 1 but i forgot to put that here. I executed this command properly while running it. It's often a good idea, if you're asking about a command, to copy and paste exactly what you enter rather than retyping it, so you don't make this kind of mistake. > While running a program on cluster I came to know that u need to give machinefile as an input to find hosts/slaves in your cluster network. But I could not get how exactly I can implement it. > Doesn't your installed version of MPICH include documentation, such as man pages? I can't just quote from the ones on the systems I use because what we have is OpenMPI, and some of the details of arguments to mpirun could be different. Anyway, if you don't have local documentation or can't make sense of it, here's the documentation page at the official MPICH site: http://www.mpich.org/documentation/guides/ and in particular http://www.mpich.org/static/downloads/3.0.4/mpich-3.0.4-README.txt has a simple example of using the -machinefile option to say which computers you want to run the program on. (Notice also that there seem to be other options for specifying this.) I can't quite tell from the documentation whether you first have to start some kind of background server process with the command "mpd". Once I again I ask: Have you been able to run any MPI programs on this system? among other things that would tell you whether you need that "mpd" command first. -- B. L.
