Where: {NP} is Total number of threads in the test {Working Dir} is the directory where files get created {Machine File} is a list of clients involved in the test, this is either created by hand, or by a scheduler {IOR Pathname} The full path to IOR, this must be accessible on all clients {FileSize} The size of the file each thread will use. This should be a multiple of client memory, to prevent cache effects.
