(which is currently the default, although we may argue over this later
:-) ), a new field in the ompi_proc_t named proc_hostname will have
the string hostname of that peer. If 0, this field will be NULL.
This allows for printing nicer error messages in environments where
peer hostnames are not otherwise easily obtainable, such as the mvapi
BTL (requested by Sandia, who has both a *huge* number of nodes and
6GB of RAM per node, so they don't care about the extra memory usage
;-) ).

to make sure that we need to export this variable out to the MCA layer.

exit out, rather than trying to have the pls exit. Since singletons
weren't started with a pls, there's no way the pls is going to be
able to kill the process. So just exit and save the error message.

- We had a bad conditional choice, such that asking for pvfs2 would
result in pvfs trying to build as well, which was going to fail.
- We didn't try to link in the libray for PVFS2's adio component.
- We were clobbering romio_flags, so it was impossible to pass
flags to romio (like the selection of filesystems)

- LDFLAGS set at the top level of Open MPI were not passed to the
ROMIO configure script
- If ROMIO was explicitly required (with --enable-io-romio) and
not able to be built, abort OMPI's configure script.
This needs to go to the v1.0 and v1.1 branches.

- change MASK behavior for tags - we need the upper bit to be whether
the tag is reseved or not. MPI_ANY_TAG should not pull off any
reserved tag communication

spewing out of here.

message from a known peer (not MPI_ANY_SOURCE) then we can attach the
remote proc and initialize the convertor as soon as we know the data-type,
and the count (so basically in the _INIT macro). If it's not the case, then
create them in the _MATCHED macro (as in the original version). Of course,
beforeinitializing the convertor we check that there will be some data
in the message.
This commit, plus the convertor improvements from few days ago, lower the
latency for my test case environment (mvapi) by 0.1 microseconds. The convertor
now is as slim as it can be, I don't think there is anything else to
remove/improve.
