This commit was SVN r15924.
The following SVN revisions from the original message are invalid or
inconsistent and therefore were not cross-referenced:
r15795
r15921
flag, new flags to be included when convertor is initialized
- modified pml/btl module defs and added stub functions for diagnostic
output routines to dump state of queues / endpoints
- updates to data reliability pml
This commit was SVN r9329.
- 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)
This commit was SVN r8985.
- remove redundant OBJ_CONSTRUCT in bcast
- fix up some macros in coll_sm.h
- check to ensure that if there are too many processes in the
communicator (i.e., if we couldn't fit a flag for each of them in
the control segment), then fail selection
- setup the in_use flags properly
- adapt to new mpool API
- first working copy of reduce -- not tree-baed (but still
NUMA-aware), and only processes in order from process 0 to process
N-1 -- do not have a tree-based and/or commutative version yet
(i.e., process the results in whatever order they arrive)
Reduce now passes the new ibm reduce_big.c test. Woo hoo! Time to
declare success for the evening (and run the intel test tomorrow).
This commit was SVN r7379.
- finally added "in use" flags -- one flag protects a set of segments
- these flags now used in bcast to protect (for example) when a
message is so long that the root loops around the segments and has
to re-use old segments -- now it knows that it has to wait until the
non-root processes have finished with that set of segments before it
can start using them
- implement allreduce as a reduce followed by a bcast (per discussion
with rich)
- removed some redundant data on various data structures
- implemented query MCA param ("coll_sm_shared_mem_used_data") that
tells you how much shared memory will be used for a given set of MCA
params (e.g., number of segments, etc.). For example:
ompi_info --mca coll_sm_info_num_procs 4 --param coll sm | \
grep shared_mem_used_data
tells you that for the default MCA param values (as of r7172), for 4
processes, sm will use 548864 bytes of shared memory for its data
transfer section
- remove a bunch of .c files from the Makefile.am that aren't
implemented yet (i.e., all they do is return ERR_NOT_IMPLEMENTED)
Now on to the big Altix to test that this stuff really works...
This commit was SVN r7205.
The following SVN revision numbers were found above:
r7172 --> open-mpi/ompi@bc72a7722b
- bcast now works properly for root!=0 and multi-fragment messages
- destroy mpool when communicator is destroyed
Still need to implement:
- "in use" flags for groups of fragments so that "wrapping around" in
the data segment doesn't overwrite not-yet-read data
- ensure that shared memory isn't removed before all processes have
finished with it (e.g., during COMM_FREE)
This commit was SVN r7172.
