- split mpif.h into mpif.h and mpif-common.h[.in]
- mpif-common.h is included by various f90 things and contains output
from configure
- mpif.h defines some f77-specific stuff and then includes
mpif-common.h

less than we posted for). We were passing by value, so this update was
not being propgated back up the stack and we could segfault. Make the
count argument a pointer so that updates will be passed as expected.
This needs to go to the v1.1 branch

comment in ompi_comm_invalid() in
source:/trunk/ompi/communicator/communicator.h.
Short version:
- ompi_comm_invalid() returns TRUE for MPI_COMM_NULL
- therefore MPI_COMM_C2F needs to explicitly check for MPI_COMM_NULL
(because it uses ompi_comm_invalid())
- make ~20 MPI functions only call ompi_comm_invalid() instead of
calling ompi_comm_invalid() *and* checking for MPI_COMM_NULL (~40 MPI
functions already only called ompi_comm_invalid() -- we should be
consistent)
- similar issue for ompi_win_invalid(), so I added a cross-referencing
comment in win.h and fixed MPI_WIN_SET_NAME to only call
ompi_win_invalid() (and not check for MPI_WIN_NULL)

pipeline. See lengthy comment in iof_base_endpoint.c for the details, but
the short version is that we shouldn't set O_NONBLOCK on standard I/O
file descriptors, so we no longer do.

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.

reentrant for free(), so we can't call free() from inside an sbrk() handler.
The solution is never call sbrk() with a negative number. The mmap() allocator
used for large allocations does not have this problem and continues to give
memory back to the OS as soon as possible.
This should go to both the v1.1 and v1.0 branches.

derefence through it. It is legal for endpoint_addr to be NULL in the
destructor because if btl_tcp_add_procs() -> btl_tcp_proc_insert()
returns UNREACH, then endpoint_addr will be NULL and we'll OBJ_RELEASE
it.

option as discussed on the devel-core mailing list. The Big
Difference is that instead of hard-coding the strings "/lib" and
"/bin" in to append to the prefix, we append the basename of the local
libdir and bindir. Hence, if your libdir is $prefix/lib64, we'll
append /lib64 to construct the remote node's LD_LIBRARY_PATH (etc.).
Also appended the orterun.1 man page to include a description of
--prefix, how it is constructed, what it handles / what it does not,
etc.

Sorry for committing configure changes during the day, but this is
necessary for some testing via multiple people at different sites.

easier to do event accounting that way
* greatly increase receive event and buffer sizes. We're still about half
of what Cray defaults to, so I don't feel bad about the increases
* Implement a pre-pinning optimization for eager fragments - will be
pinned on first use and left pinned for the life of the fragment
* Since we can't have two receive frag callbacks fired at the same time,
don't have receive free list - just keep one receive fragment in the
module. Saves a big free list and all that interaction.

things I found:
- Locking should prevent it from happening (I think), but there was a
race condition in the component progress -- a callback could be
triggered that would free the request before it was off the outstanding
requests list.
- When pulling a request off the component free list, make sure to
reinitialize the free_called state on the IO request. This was
what was causing Edgar's failures
- In the request cleanup code, pull the request out of the per-
component free list before returning to the free list. This
probably would cause asserts to fire, although it looks like
I wrote the loops such that it would have been memory safe if
the asserts didn't fire. Not really sure why I did that, but
let's try it again...
This should go to the v1.0 and v1.1 branches.

(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
;-) ).
