Use of the old ompi_free_list_t and ompi_free_list_item_t is
deprecated. These classes will be removed in a future commit.
This commit updates the entire code base to use opal_free_list_t and
opal_free_list_item_t.
Notes:
OMPI_FREE_LIST_*_MT -> opal_free_list_* (uses opal_using_threads ())
Signed-off-by: Nathan Hjelm <hjelmn@lanl.gov>
Please verify your components have been updated correctly. Keep in
mind that in terms of threading:
OPAL_FREE_LIST_GET -> opal_free_list_get_st
OPAL_FREE_LIST_RETURN -> opal_free_list_return_st
I used the opal_using_threads() variant anytime it appeared multiple
threads could be operating on the free list. If this is not the case
update to _st. If multiple threads are always in use change to _mt.
This commit adds an owner file in each of the component directories
for each framework. This allows for a simple script to parse
the contents of the files and generate, among other things, tables
to be used on the project's wiki page. Currently there are two
"fields" in the file, an owner and a status. A tool to parse
the files and generate tables for the wiki page will be added
in a subsequent commit.
The fi_fabric function appears to free the provider string passed in
in the fabric_attr. This causes MCA to free an invalid pointer when
the parameter is freed.

Squash compiler warnings now showing up in the
query methods for the mtls. Cast pointers to the different
mtl module specific types to the mca_base_module_t.
Also, fix up a missing extern in mtl_psm_types.h.
This was causing "multiple definition" errors when building
the mca_mtl_psm.so shared library.
Switch to using the query/priority method for selecting
MTLs. This switch was motivated by the fact that now
on some platforms, its possible for multiple MTLs to
be initializable, but only one MTL should be selected.
In addition, there is a complication with the PSM and
IFO (with PSM provider) MTLs owing to the fact that
they cannot both intialize the underlying PSM context,
i.e. only one call to psm_init is allowed per process.
The mxm component has not been compiled as the author
doesn't currently have access to a system with a recent
enough mxm installed to allow for a compile.
The portals4, ofi, and psm components have been checked
for compilation. The ofi and psm components have been
checked for runtime correctness on a intel/qlogic system
with up to date PSM installed.
PSM has issues when trying calling psm_ep_connect() more than once for a
specific peer. Use the psm_ep_connect mask argument to avoid connecting
to processes that are already connected.
OMPI ticket #268.
We recognize that this means other users of OPAL will need to "wrap" the opal_process_name_t if they desire to abstract it in some fashion. This is regrettable, and we are looking at possible alternatives that might mitigate that requirement. Meantime, however, we have to put the needs of the OMPI community first, and are taking this step to restore hetero and SPARC support.
When running many ranks on a single node using PSM, it's possible to
exhaust the network hardware contexts (there are 16). This patch checks
if only a single node is being used. If so, the 'ipath' component of PSM
is disabled and no hardware contexts are opened.
