bb3d258562 Round up a few places where PATH_MAX was used instead of
OMPI_PATH_MAX.  Thanks to Andrea Iob for the bug report.

1872a7b75d This change allows the trunk to be compiled with Sun
Studio compilers again. It has been broken since
1/14/2009 when some changes exposed a bug in autoconf
and how it handles support for the restrict keyword.
Basically, Sun Studio C supports the restrict keyword
but Sun Studio C++ does not.

I am also pursuing a fix with the autoconf folks, but
this change was needed to get things building again.

03434f8f10 Some compilers complain about casting a pointer to a integer type with a different
size. The correct way is to cast to an integer type that has the same length, and
then allow the compiler to upgrade to the read type.

e9c50a29ba Some (rare) platforms only have a #define for htonl and friends,
but not anything in libc.  Which causes an incorrect answer for
AC_CHECK_FUNCS.  Work around that by also checking for the
#define.

b0cbeb0b41 - Add detection of __attribute__((hot)) and __attribute__((cold))
to allow explicit grouping of hot functions into similar code
   sections upon link-time. Should decrease TLB misses (iff the code-
   section is really too large)...
   Candidates for __opal_attribute_hot__ are MPI_Isend MPI_Irecv,
   MPI_Wait, MPI_Waitall
   Candidates for __opal_attribute_cold__ are MPI_Init, MPI_Finalize and
   MPI_Abort...

e0fb3957cb Patch from Brian:
* The opal_sys_timer_get_cycles() call was implemented for
   Sparc v9 using inline assembly, but not in the assembly files.
   This would only currently matter on Linux Sparc systems using
   a compiler that didn't support inline assembly (not many of
   those), but it should be there for completion.
 * The linux timer component would always build on non-Alpha
   platforms, rather than only building on platforms where
   opal_sys_timer_get_cycles() was implemented.  This would
   only matter on a very narrow set of platforms that we don't
   really support, but still, it could be more right.  We now
   only build the component on platforms where we have the
   assembly call to get the cycle counter.
 * Added a comment to opal/sys/timer.h to note that the linux
   timer component needed to be updated if another platform was
   added.

This should be harmless to commit.  It will only really change
behaviors on platforms we don't have assembly support for, which
currently won't make it through configure.  It really only matters
when (if?) we support atomic operations through libatomic_ops.

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.

  * Move the networking code in opal that isn't directly related to if
    detection into net.h
  * Add quicky function to get the port out of either a sockaddr_in
    or sockaddr_in6, saving a bunch of code in the oob.

0ba47105ed Merge the /tmp/jms-installdirs-trunk branch into the trunk. This
finally brings in functionality that is already on the 1.2 branch, and
was developed and tested in the v1.2ofed branch (and other places).

Short version of new features:

 * Support for ibv_fork_init() 
 * Automatically fill in the openib BTL bandwidth value by 
   querying the HCA port 
 * Installdirs functionality 
 * Fixes to always use -I in the Fortran wrapper compilers (#924) 
 * Gleb's mpool updates 
 * Remove some kruft in btl/openib/configure.m4, therefore 
   fixing the harmless warnings noted in #665 
 * Bunches of updates to the Linux RPM spec file 

I.e., effectively the same thing that r14411 brought to the v1.2
branch.

Also effectively brought in r14432 and r14433 (some fixes on top of
the original r14411 commit to v1.2).  Still need to bring in the moral
equivalent of r14445 after this commit (fixes to installdirs).

dce72aab70 Prior to Mac OS X 10.3, the length modifier "ll" wasn't
supported, but "q" was for long long.  This isn't ANSI
C and causes a warning when using PRI?64 macros.  We
don't support versions prior to OS X 10.3, so we dont'
need such backward compatibility.  Instead, redefine
the macros to be "ll", which is ANSI C and doesn't
cause a compiler warning.

4890636581 Work around what appears to be an odd error in the pathscale compiler where
the dispatch function opal_atomic_cmpset_acq_xx was used to call
opal_atomic_cmpset_acq_32  would cause the compiler / linker to fix up a
jump address to be itself, leading to an infinite loop.

We're still looking into exactly what caused this, but during the
investigation into the hang, we determined that the compiler (both pathcc
and gcc) weren't always inlining both the call to opal_atomic_cmpset_acq_xx
and opal_atomic_cmpset_acq_32, meaning there was a function call in
opal_atomic_lock.  The atomic lock will always be 32 bit, so there's no
need for the dispatch function, so might as well remove the dispatch
function that may or may not be inlined.

A bug fix that leads to potentially better performance.  Gotta love the
few times that happens...

to flush all writes pending (ie, the data being protected) out of the memory

full mb, which is at least slightly less intrusive.  Also, after much
thought, no need for a memory barrier in init.
