- -check-shmem-params is OFF by default. It checks OSHMEM API params and will abort on bad input
- hcoll do not save fallback coll pointers for unsupported collectives.

The library filenames for the Fortran MPI APIs have changed over time,
so update the text that refers to these libraries to be a bit more
generic.

branch; it will likely be easiest just to copy over a new copy of
bullet 3)
This commit was SVN r30994.
The datatype unpacking code assumes that the packed datatype buffer has the
same alignment as an OPAL_PTRDIFF_TYPE. This was not enforced by the rdma
one-sided component. I changed the ordering and sized of various osc/rdma
headers to ensure their sizes are a multiple of 8-bytes and modified the
fragment allocation call to ensure all headers are 8-byte aligned. While
not the cleanest way to handle this situation it should resolve the issue.
Fixes trac:4315

The following Trac tickets were found above:
Ticket 4315 --> https://svn.open-mpi.org/trac/ompi/ticket/4315
assumes the send request is derived from mca_pml_base_send_request_t,
but this is not true for pml cm, so we end up freeing invalid pointer.
We cannot take the data pointer from the pml send request, so we pass
the allocated buffer pointer in req_complete_cb_data, and put the
osc_rdma_module pointer in that buffer as well.
Previously, osc_pt2pt was used with pml_cm which didn't have this
problem.

In the function sstore_stage_select() the local variables
were set up and defined. Unfortunately this function was
never called. This patch moves variable set up to the
sstore_stage_register() function and checks the return
values of the variable initialization.

* clang warning stomp
* memory barrier for volatile variable use
These can go to 1.7.5 or can slip to v1.8 -- RM decision.

* Older versions of libusnic_verbs actually return 0 when querying for
an unknown port. So also check for a magic ID in the returned data
to *really* know if the usnic extensions are supported.
* Use a union (in the common_verbs area) and memcpy (in the btl) to
avoid undefined C type aliasing behavior.
* Ensure to memset the function table to 0 if the usnic extensions
are not supported.

In the OPAL_ENABLE_FT_CR code path there used to be a variable
'mca_base_component_distill_checkpoint_ready' which got removed.
The FT code was not compiling and while trying to get it to compile
again the old variable was #ifdef'd out. This re-introduces the
variable with a new name 'opal_base_distill_checkpoint_ready'
and enables the code previously #ifdef'd out.
This removes the last hack introduced to get the FT code to compile
again.
This commit was SVN r30928.
When compiling --with-ft there are a few compiler warnings about
unused variables. This patch fixes those compiler warnings.
This commit was SVN r30927.
Realistically, the usnic BTL doesn't need to know anything about the
underlying transport except for its header length (so that it knows
where the payload begins in a received buffer). So remove the use of
the specific transport prefix union and just rely on the usnic verbs
extension to tell us what the header length is if we're using the
usNIC/UDP transport, or sizeof(struct ibv_grh) if we're using usNIC/L2
transport.
This commit was SVN r30914.
Check the IBV_TRANSPORT_* values. In the case of IBV_TRANSPORT_IWARP,
there's an ambiguity and we need to also check to see whether the
usnic verbs externsion probe exists.
This commit was SVN r30913.
If they exist, call the usnic verbs extensions to both enable UDP
support and get the UD receiver header length that should be used
(rather than assume 40/struct GRH).
