- it will now wait for the child procs to exit then kill off the daemons - if orted is in your path it will automatically be found, or you can specify its location. - your LD_LIBRARY_PATH is now forwarded to the backend to make it easier to use shared libraries in nonstandard places Still need to work on cleanup on the backend nodes. This commit was SVN r6462.

/**
|
|
* Header file for the bproc launcher. This launcher is actually split into 2
|
|
* modules: pls_bproc & pls_bproc_orted. The general idea behind this launcher is:
|
|
* 1. pls_bproc is called by orterun. It figures out the process mapping and
|
|
* launches orted's on the nodes
|
|
* 2. pls_bproc_orted is called by orted. This module intializes either a pty or
|
|
* pipes, places symlinks to them in well know points of the filesystem, and
|
|
* sets up the io forwarding. It then sends an ack back to orterun.
|
|
* 3. pls_bproc waits for an ack to come back from the orteds, then does several
|
|
* parallel launches of the application processes. The number of launches is
|
|
* equal to the maximum number of processes on a node. For example, if there
|
|
* were 2 processes assigned to node 1, and 1 process asigned to node 2, we
|
|
* would do a parallel launch that launches on process on each node, then
|
|
* another which launches another process on node 1.
