916397f358 Use thread specific data and static buffers for the return type of
opal_net_get_hostname() rather than malloc, because no one was freeing
the buffer and the common use case was for printfs, where calling
free is a pain.

b6c60dfc07 Bring over the extra debugging output that helped a user find his NSF mount problems. This just adds ERROR_LOG messages when the session directory creation process fails so we can see where it is happening - really helps users (and us as well) figure out what specifically went wrong.

d837f1446b It is work around for Ticket #1092.
It will prevent the error failure in openib finalize
but it doesn't resolve the actual issue. I guess that
oneside tests some how allocates memory (mpool?) and doesn't 
release it. Need to check it.

3bc940ac27 Fix three things from r15474 (thanks to Brian for noticing):
* bml.h had a change that introduced a variable named "_order" to
   avoid a conflict with a local variable.  The namespace starting
   with _ belongs to the os/compiler/kernel/not us.  So we can't start
   symbols with _.  So I replaced it with arg_order, and also updated
   the threaded equivalent of the macro that was modified.
 * in btl_openib_proc.c, one opal_output accidentally had its string
   reverted from "ompi_modex_recv..." to
   "mca_pml_base_modex_recv....".  This was fixed.
 * The change to ompi/runtime/ompi_preconnect.c was entirely
   reverted; it was an artifact of debugging.

8ace07efed This commit brings in two major things:
1. Galen's fine-grain control of queue pair resources in the openib
   BTL.
1. Pasha's new implementation of asychronous HCA event handling.

Pasha's new implementation doesn't take much explanation, but the new
"multifrag" stuff does.  

Note that "svn merge" was not used to bring this new code from the
/tmp/ib_multifrag branch -- something Bad happened in the periodic
trunk pulls on that branch making an actual merge back to the trunk
effectively impossible (i.e., lots and lots of arbitrary conflicts and
artifical changes).  :-(

== Fine-grain control of queue pair resources ==

Galen's fine-grain control of queue pair resources to the OpenIB BTL
(thanks to Gleb for fixing broken code and providing additional
functionality, Pasha for finding broken code, and Jeff for doing all
the svn work and regression testing).

Prior to this commit, the OpenIB BTL created two queue pairs: one for
eager size fragments and one for max send size fragments.  When the
use of the shared receive queue (SRQ) was specified (via "-mca
btl_openib_use_srq 1"), these QPs would use a shared receive queue for
receive buffers instead of the default per-peer (PP) receive queues
and buffers.  One consequence of this design is that receive buffer
utilization (the size of the data received as a percentage of the
receive buffer used for the data) was quite poor for a number of
applications.

The new design allows multiple QPs to be specified at runtime.  Each
QP can be setup to use PP or SRQ receive buffers as well as giving
fine-grained control over receive buffer size, number of receive
buffers to post, when to replenish the receive queue (low water mark)
and for SRQ QPs, the number of outstanding sends can also be
specified.  The following is an example of the syntax to describe QPs
to the OpenIB BTL using the new MCA parameter btl_openib_receive_queues:

{{{
-mca btl_openib_receive_queues \
     "P,128,16,4;S,1024,256,128,32;S,4096,256,128,32;S,65536,256,128,32"
}}}

Each QP description is delimited by ";" (semicolon) with individual
fields of the QP description delimited by "," (comma).  The above
example therefore describes 4 QPs.

The first QP is:

    P,128,16,4

Meaning: per-peer receive buffer QPs are indicated by a starting field
of "P"; the first QP (shown above) is therefore a per-peer based QP.
The second field indicates the size of the receive buffer in bytes
(128 bytes).  The third field indicates the number of receive buffers
to allocate to the QP (16).  The fourth field indicates the low
watermark for receive buffers at which time the BTL will repost
receive buffers to the QP (4).

The second QP is:

    S,1024,256,128,32

Shared receive queue based QPs are indicated by a starting field of
"S"; the second QP (shown above) is therefore a shared receive queue
based QP.  The second, third and fourth fields are the same as in the
per-peer based QP.  The fifth field is the number of outstanding sends
that are allowed at a given time on the QP (32).  This provides a
"good enough" mechanism of flow control for some regular communication
patterns.

QPs MUST be specified in ascending receive buffer size order.  This
requirement may be removed prior to 1.3 release.

e782da00e0 Don't allow the same communicator to be used in a multi-threaded build by several
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 (!).

d109e9a6f4 Roll in the Voltaire core/socket/etc process mapping implementation. Only change I made was to cleanup some of the diagnostic output in the odls_default component so it uses the -mca odls_base_verbose parameter.
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.

2bded34a1d Fix a problem observed by Brian where processes launched local to mpirun lost their environment except for MCA params.
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).

59dc6b95f3 Modifications in the way user-specified modules are loaded. Once we get the list of filenames from the libtool, we add the statically defined ones and then based on the include/exclude string we only keep the ones requested by the user. If no include/exclude was provided, we keep [as expected] everything. Once we have the list of whatever is requested we open them. Therefore, as an example, if the user specify "--mca pml ob1" we will never try to load/open/init DR nor CM.
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.
