large clusters, as there's no way to wire them up in 10 seconds most of the

I know it's just a technicality, but it is time to address such things rather than just letting them continue to propagate. :-)

This has now been corrected. The singleton startup will dutifully call the mapper framework so that the proper data storage locations get initialized. Unfortunately, we then had to instruct the RMAPS not to allocate a vpid range for this job - otherwise, it would make a mistake and think there were two processes in it. Hence, a change was required to RMAPS to tell it "map this job, but don't allocate a vpid range for it".
This change will need to migrate across to 1.2 after it "soaks" the appropriate time.

rc (which is -1 or 4 if we hit this case) resulted in an odd error that a
signal killed the proc (instead of a startup error, as is reality).
Instead, use the W_EXITCODE macro (if available) to build up an exit
code that has an error code for exit status, but does not make it look
like the process died from a signal

1. no -np provided - put one proc/node across all allocated nodes
2. -np N provided, N > #nodes - we print a pretty error message and exit
3. -np N provided, N <= #nodes - put one proc/node across N nodes
I also added a new orte constant (ORTE_ERR_SILENT) that allows us to pass up the chain that an error was encountered, but NOT print ORTE_ERROR_LOG messages. This is intended to be used for cases where the error we encounter is NOT an orte error, but rather is one associated with incorrect user input (e.g., the preceding case 2). In such cases, there is no point in printing an ORTE_ERROR_LOG chain of messages as it isn't an orte error.

I found only two places that were looking at the tokens:
1. the odls - we used the tokens to separately process the globals container data from everything else. In this case, I left the subscription that returned the globals data alone, but "stripped" the subscription that returned the launch data for the procs. These subscriptions have nothing to do with the xcast message.
2. the pml_base_modex - the callback function was getting process names from the returned tokens. Actually, this function was doing a very bad thing - it was assuming that the first token returned was *always* the process name. This is currently true, but is one of those assumptions that someone could have easily changed - and suddenly found the system inexplicably failing. I modified the function to (a) get the name sent back to us, (b) "stripped" the value structures of tokens and segment strings, and (c) correctly obtained process names from the returned values. I also reindented the heck out of the code so it was legible (at least, to my old eyes).

Obviously, people like bproc will have to get the app_num via another avenue...but that's a problem for another day. Several options are easily available.

1. implement and enable the non-described buffer operations. I will send out a more detailed explanation separately. However, this mode of operation (which is now the default) significantly reduces message size during startup. If you want the described buffers, set the mca param "-mca dss_describe_buffer 1".
2. revise the xcast system to support both linear and binomial tree broadcast methods. Since we are seeing scenarios where the binomiall tree can cause problems, I have made the linear method the default. To run with the binomial tree, set the mca param "-mca oob_xcast_mode binomial".
3. add some detailed timing reports to the xcast operation. These are enabled via "-mca oob_xcast_timing 1".
4. add some more unit tests for the dss and gpr (focused on support for the non-described buffer)

Ralph identified the problem, I tracked down ''where'' the fd was
being closed, and Brian figured out ''why'' (and the fix).
What was happening is that a remote process was closing its
stdout/stderr and therefore sending a 0-byte IOF message to mpirun.
mpirun, in turn, closed the iof endpoint associated with that stream
(i.e., stdout/stderr). IOF does this to handle the case where
mpirun's stdin is closed -- this therefore causes the stdin on all the
ORTE-started processes to have their stdin's closed as well.
So the workaround here is to check that if we get a 0-byte IOF message
on a sink (indicating a remote closure), and if that sink is the
special stdout or stderr stream, don't actually close anything in the
local process.
