mpi_show_mpi_alloc_mem_leaks
When activated, MPI_FINALIZE displays a list of memory allocations
from MPI_ALLOC_MEM that were not freed by MPI_FREE_MEM (in each MPI
process).
* If set to a positive integer, display only that many leaks.
* If set to a negative integer, display all leaks.
* If set to 0, do not show any leaks.

some time ago (last summer) that included checking for M_TRIM_THRESHOLD and
M_MMAP_MAX, unfortunately we didn't include <malloc.h> which is where these
are define, so disabling sbrk for the registration cache has been busted for
some time.

mca_mpool_base_page_size_log. They are exported by the mpool/base/base.h,
if some other code need them, then it should include this file
instead of having it's own redefinition of these externals.

needlessly registered in multiple different places, and none of them
had a good help string. There was also an inconsistent check for
setting both mpi_leave_pinned and mpi_leave_pinned_pipeline (i.e., it
was only in ob1). This commit moves the registration of these params
to one central place (ompi/runtime/ompi_mpi_params.c, with all other
mpi_* MCA params) and uses globals to propagate the values as
relevant. The error check was also moved to the central location to
ensure that we can consistency everywhere.

all platforms. The only exceptions (and I will not deal with them
anytime soon) are on Windows:
- the write functions which require the length to be an int when it's
a size_t on all UNIX variants.
- all iovec manipulation functions where the iov_len is again an int
when it's a size_t on most of the UNIXes.
As these only happens on Windows, so I think we're set for now :)

sbrk and the use of mmap(). So rather than checking just for mallopt(),
we should also be checking for those defines when determining if we can
disable giving memory back to the OS or not.

allocation. This is necessary to detect if the user requests a specific
mpool for the allocationi. Searching the key values for a specific mpool
name does not work for the case that the user provides an info object
without mpool specific information (see Ticket #254).
- In the case that the user provides a info object without requesting a
specific mpool we use malloc to allocate buffer instead of returning
NULL (fix for Ticket #254 )

where to look for registrations that were used in the alloc/free code don't
work (because the memory returned from malloc() -- whowever gets around to
calling it) might actually be registered already. So just call malloc
and free directly and avoid the whole issue when leave pinned is on. After
all, you have to pay the registration cost sometime, and if leave pinned
is on, you only have to pay it once. It makes things much simpler to
have that once be at first use rather than during ALLOC_MEM, and as far
as I can read, we're still standards conformant this way.

1) don't need tree if memory is just malloc'd
2) fix memory and free list leak..
3) deregister first and then free... doh..
This commit was SVN r10251.
Added a tree to track memory allocation from MPI_Alloc_mem, this allows us to
free the registrations in a sane fashion.. also should be faster..
This commit was SVN r10248.
2. fix for MPI_Free_mem, was calling deregister but never called mpool_free.. so
we leaked memory. Still an open issue here though, if the memory is alloc'd
and the mpool doesn't create and cache a registration, we will never find the
mpool to free with.

add object size to opal class
no longer need the size when allocating a new object as this is stored in
the class structure

Previous rev. maintained state on the communicator used for acking duplicate
fragments, but the communicator may be destroyed prior to successfull
delivery of an ack to the peer. We must therefore maintain this state
globally on a per peer, not a per peer, per communicator basis.
This requires that we use a global rank on the wire and translate this as
appropriate to a local rank within the communicator.

to let the PML (or io, more generally the low level request manager)
to have it's own release function (what was before the req_fini). This
function will only be called from the low level while the req_free will
be called from the upper level (MPI layer) in order to mark the request
as not used by the user anymore.
From the request point of view the requests will be marked as inactive
everytime we read their status (true for persistent as well). As
MPI_REQUEST_NULL is already marked as inactive, the test and wait functions
are simpler. The drawback is that now we have to change in the
ompi_request_{test|wait} the req_status of the request once we get it's
status.

- move files out of toplevel include/ and etc/, moving it into the
sub-projects
- rather than including config headers with <project>/include,
have them as <project>
- require all headers to be included with a project prefix, with
the exception of the config headers ({opal,orte,ompi}_config.h
mpi.h, and mpif.h)

deallocation came from the allocator (malloc, fee, etc) or somewhere
else (the user calling mmap/munmap, etc). Going to be used by Galen
to determine if it is worth searching the allocations tree
Set flag if it is possible to intercept mmap (not always possible
due to a circular dependency between mmap, dlsym, and calloc)

component/base Makefile.am files, reducing the time configure spends
stamping out Makefiles at the end
* Install base_impl.h file when devel-headers are being installed
This commit was SVN r8200.
When compiling C++ code that includes something that looks for the C++
header file "memory" (stupid C++ headers not having .h extensions), it
goes through the header file search path, which includes $(topsrcdir)/opal,
so it finds the directory $(topsrcdir)/opal/memory/ and tries to load
that as the memory header file and all goes downhill.

--with-devel-headers is given to configure:
* allocator, rcache, and mpool were putting things in the wrong place
* timer wasn't installing the inline implementations at all

searching the tree. Modified the memory callback to search the tree at each
page boundary for registrations. This is necessary as an application may
malloc memory and send out of any portion of that memory, even discontiguous
regions.

add misc asserts to check for proper reference counting.
ugly hack 1 -- use mallopt to never release memory ala sbrk - this is
commented out in mca_btl_mvapi_component_init
ugly hack 2 -- test registrations comming out of the tree via rcache_find, for
an unknown reason the tree is returning registrations where the address is not
within the base or bound of the registration. If this happens, we return
NULL.
comment out code to enable mem hooks if leave_pinned is set, note we can do
this via an mca param and will default it to leave_pinned with mem_hooks when
we iron out these issues.
I am adding a unit test for the rcache. Note that we have a unit test for the
rb tree but the compare function is significantly different than that used for
registrations. After we have tracked down the issues with rcache_rb we will
remove the above hacks.

be used in MPI_Alloc_mem operations. Note that we found an interesting bug in
which if memory was allocated by the sm mpool (via mmap) and then registered
via the mvapi mpool, the registration would fail on certain systems.
Added mca param mpool_base_use_mem_hooks, set to 1 to enable the memory hooks
so that memory is deregistered if the user frees it behind our back. This is
only useful if the mca param mpi_leave_pinned is also set to 1. Otherwise all
registrations are deregistered within the MPI library or via
MPI_Free_buf. After testing we should probably set both mpi_leave_pinned and
mpool_base_use_mem_hooks to default to 1.

AM_INIT_AUTOMAKE, instead of the deprecated version.
* Work around dumbness in modern AC_INIT that requires the version
number to be set at autoconf time (instead of at configure time, as
it was before). Set the version number, minus the subversion r number,
at autoconf time. Override the internal variables to include the r
number (if needed) at configure time. Basically, the right thing
should always happen. The only place it might not is the version
reported as part of configure --help will not have an r number.
* Since AM_INIT_AUTOMAKE taks a list of options, no need to specify
them in all the Makefile.am files.
* Addes support for subdir-objects, meaning that object files are put
in the directory containing source files, even if the Makefile.am is
in another directory. This should start making it feasible to
reduce the number of Makefile.am files we have in the tree, which
will greatly reduce the time to run autogen and configure.

add a -I to find the included ltdl.h (vs. a system-installed ltdl.h)
- Clean up kruft in a bunch of Makefile.am's to remove now-unnecessary
AM_CPPFLAGS settings to get static-components.h for each framework
- Move the component_repository API functions out of opal/mca/base/base.h
and into opal/mca/base/mca_base_component_repository.h in order to
decrease unnecessary dependencies (e.g., before this, almost
everything in the tree depended on ltdl.h, which is unnecessary --
only a small number of files really need ltdl.h)

multiple components to share a single mpool module (e.g., the
ptl/btl and coll sm components).
- Re-tool the ptl, btl, and coll sm components to first look for the
target mpool module, and if they don't find it, to create it.
- coll sm component now correctly identifies when it is supposed to
run or not (i.e., if all the processes in the communicator are on
the same host). Now we just need to fill in some algorithms. :-)
This commit was SVN r6530.
- move mpool and allocator frameworks back to ompi (from opal)
- specialize the ompi_free_list class to use an mpool instance
- un-specialize opal_free_list to *not* use mpool; just use malloc/free
