In OMPI 2.1.2, buildrpm.sh could work with a value of rpmtopdir that was
set in the environment. In newer versions this is no longer true,
causing such values to be ignored. This patch adds a new argument to
buildrpm.sh, -R, which allows the user to specify where to build the
RPMs.

The new routine transfers the data asynchronously from the source PE to all
PEs in the OpenSHMEM job. The routine returns immediately. The source and
target buffers are reusable only after the completion of the routine.
After the data is transferred to the target buffers, the counter object
is updated atomically. The counter object can be read either using atomic
operations such as shmem_atomic_fetch or can use point-to-point synchronization
routines such as shmem_wait_until and shmem_test.

make-authors.pl checks that .git exists and is a directory before
getting the git log - but when a repo is checked out as a submodule of a
larger repository, .git is not a directory, it's just a text file. This
can cause make-authors.pl to terminate inappropriately.

There are a couple MPI_Alltoallv calls in ad_gpfs_aggrs.c where the
send/recv data comes from places like req[r].lens, and the send
buffer and send displacements for example were being calculated as
sbuf = pick one of the reqs: req[bottom].lens
sdisps[r] = req[r].lens - req[bottom].lens
which might be okay if the .lens was data inside of req[] so they'd
all be close to each other. But each .lens field is just a pointer
that's malloced, so those addresses can be all over the place, so the
integer-sized sdisps[] isn't safe.
I changed it to have a new extra array sbuf and rbuf for those two
Alltoallv calls, and copied the data into the sbuf from the same
locations it used to be setting up the sdisps[] at, and after the
Alltoallv I copy the data out of the new rbuf into the same
locations it used to be setting up the rdisps[] at.
For what it's worth I was able to get this to fail -np 2 on a GPFS
filesystem with hints romio_cb_write enable. I didn't whittle the
test down to something small, but it was failing in an
MPI_File_write_all call.

the return code was ignored. So the code fell back on both btl_put and

In fint_2_int.h there are some conversion macros for logicals. It has
one path for OMPI_SIZEOF_FORTRAN_LOGICAL != SIZEOF_INT where a new array
would be allocated and the conversions then might expand to
c_array[i] = (array[i] == 0 ? 0 : 1)
and another path for OMPI_SIZEOF_FORTRAN_LOGICAL == SIZEOF_INT where it
does things "in place", so the same conversion there would just be
array[i] = (array[i] == 0 ? 0 : 1)
The problem is some of the logical arrays being converted are INPUT
arguments. And it's possible for some compilers to even put the argument
in read-only memory so the above "in place" conversion SEGV's. A
testcase I have used
call MPI_CART_SUB(oldcomm, (/.true.,.false./), newcomm, ierr)
and gfortran put the second arg in read-only mem.
In cart_sub_f.c you can trace the ompi_fortran_logical_t *remain_dims arg.
remain_dims[] is for input only, but the file uses
OMPI_LOGICAL_ARRAY_NAME_DECL(remain_dims);
OMPI_ARRAY_LOGICAL_2_INT(remain_dims, ndims);
PMPI_Cart_sub(..., OMPI_LOGICAL_ARRAY_NAME_CONVERT(remain_dims), ...);
OMPI_ARRAY_INT_2_LOGICAL(remain_dims, ndims);
to convert it to c-ints make a C call then restore it to Fortran logicals
before returning.
It's not always wrong to convert purely in-place, eg cart_get_f.c has
a periods[] that's exclusively for OUTPUT and it would be fine with the
macros as they were. But I still say the macros are invalid because they
don't distinguish whether they're being used on INPUT or OUTPUT args and
thus they can't be used in a way that's legal for both cases.
It might be possible to fix the macros by adding more of them so that
cart_create_f.c and cart_get_f.c would use different macros that give
more context. But my fix here is just to turn off the first block and
make all paths run as if OMPI_SIZEOF_FORTRAN_LOGICAL != SIZEOF_INT.
The main macros that get enlarged by this change are
define OMPI_ARRAY_LOGICAL_2_INT_ALLOC : mallocs now
define OMPI_ARRAY_LOGICAL_2_INT : also mallocs now
But these are only used in 4 places, three of which are the purpose of
this checkin, to avoid the former in-place expansion of an INPUT arg:
cart_create_f.c
cart_map_f.c
cart_sub_f.c
and one of which is an OUPUT arg that was fine and that gets
unnecessarily expanded into a separate array by this checkin.
cart_get_f.c
So I think an unnecessary malloc in cart_get_f.c is the only downside
to this change, where the logicals array argument could have been used
and converted in place.
