Hello everyone, My name is Kay. I’m a huge "oom-pi" fan, but only recently have been looking at from devel perspective.
I appreciate if somebody shows me the entry point into understanding how orterun and user program interact, and more importantly how to change the way they interact. The reason: I am making a plugin for MPI support in another message passing system. This plugin is loaded from a dynamic library sometime after the process is started and is run on a separated tread. Therefore, (1) it does not receive any command line arguments, and (2) it is not allowed to use standard pipes (file descriptors 0,1, 2). With that in mind, I’de like to interface this plugin from inside so-called ARE (which is the name for the runtime environment for this particular message passing system) to our old friend ORTE. I have the option to run “are” as a user program run by orterun. $orterun are ./actual-user-program It might be wishful thinking, but I am also kindda hoping that I could get orterun out of the way all together by embedding a part of its implementation directly inside that plugin. I’de appreciate to hear your insights. Best, — Kay
