1. completely and cleanly separates responsibilities between the HNP, orted, and tool components. 2. removes all wireup messaging during launch and shutdown. 3. maintains flow control for stdin to avoid large-scale consumption of memory by orteds when large input files are forwarded. This is done using an xon/xoff protocol. 4. enables specification of stdin recipients on the mpirun cmd line. Allowed options include rank, "all", or "none". Default is rank 0. 5. creates a new MPI_Info key "ompi_stdin_target" that supports the above options for child jobs. Default is "none". 6. adds a new tool "orte-iof" that can connect to a running mpirun and display the output. Cmd line options allow selection of any combination of stdout, stderr, and stddiag. Default is stdout. 7. adds a new mpirun and orte-iof cmd line option "tag-output" that will tag each line of output with process name and stream ident. For example, "[1,0]<stdout>this is output" This is not intended for the 1.3 release as it is a major change requiring considerable soak time. This commit was SVN r19767.

\fIompi-iof\fR displays a copy of the indicated stdout, stderr, and/or stddiag streams

The program will terminate cleanly, telling the associated mpirun to close the requested
|
|
streams before exiting.
