threads to create new communicators. There is nothing in the standard about threading
and communicaotr functions, but as they include collective communications I expect the
same rules have to be applied. As such, on an incorrect MPI program we deadlock (!).

build it's possible that we have to process an ack before this function
returns. If we don't release the lock here we cause a deadlock later
in ack processing function.

Fix the blasted iof null component so it only is selected if/when directed.

You will not see any impact from this change unless you use the syntax described in ticket #1023. I've tried as many of the RAS components as possible and saw no problem - there may be issues with other RAS components that would not compile on any of my systems. Anything that appears should be trivial to fix.

(duh). The first form is the bmtree suitable for bcast, but the latter is better for reduce.
Updating default decision function accordingly.

This fixes C/R support for the trunk which regressed in r15390 due to the RTE

We no longer store whether we are a singleton in a MCA parameter, we now use a global constant. So all references to the MCA parameter must be removed.

The problem stemmed from no longer launching a local orted on the same node as mpirun. The orted would save and reuse the base environment. Mpirun didn't do that, and the odls was using the orted's globally saved environment (which wasn't being set).
This fix establishes a globally accessible base launch environment that both the orted and mpirun can utilize. Since we now use that, we don't need to pass it to the odls_launch_proc function, so remove that param from the API (and modify all components to handle the change).

There are several interesting things:
1. less NFS traffic [as we potentially access less files]
2. faster loading time [in case the user tune it's execution environment]
3. (1) + (2) -> faster startup time [at least everything which do not depend on the network]
4. MX bug will go away if the pml is specified.
5. No useless BTL will be opened, which will solve few others issues.

It solve the problem with the MPI_Aint alignment that showed up on Solaris
Sparc and on heterogeneous environments when dealing with the data-type description.
The solution is to move the displacement array from the packed array if we
detect that the local architecture required MPI_Aint to be aligned to an
MPI_Aint boundary (which is not the case for x86 architectures if MPI_Aint
is a 64 bits type).

instead of just the procs for MCW (in MCW order). Should make resolving
ptl_process_id_t structures for arbitrary communicators easier for
applications that need it.
This commit was SVN r15393.
Short description: major changes include -
1. singletons now fork/exec a local daemon to manage their operations.
2. the orte daemon code now resides in libopen-rte
3. daemons no longer use the orte triggering system during startup. Instead, they directly call back to their parent pls component to report ready to operate. A base function to count the callbacks has been provided.
I have modified all the pls components except xcpu and poe (don't understand either well enough to do it). Full functionality has been verified for rsh, SLURM, and TM systems. Compile has been verified for xgrid and gridengine.

an override here in ompi_info to force the loading of all components.
This is ok because we *only* call opal_init_util() (not orte_init() or
ompi_mpi_init()).

that exactly describes the buffer to be used as the target of the
operation
* Use the above flag to disable components setting the flag from being
used for real RDMA operations for the one-sided component (the
BTLs will still be used for RDMA transfers for the PML and for
send/receive communication for the OSC component)
