No need for any CMRs to 1.5... that was already done in CMR 2728.
This commit was SVN r24545.
The following SVN revision numbers were found above:
r22841 --> open-mpi/ompi@b400b84162
* rename ib_path_rec_service_level -> ib_path_record_service_level
* use mad.h and ib_types.h
* free all resources
* move ibv_post_recv to be just before ibv_post_send
* cleanup and beatify code
This commit was SVN r24507.
Update the CMake script for checking mca subdirs.
Add windows support for __attribute__ packed structures.
Define usleep and posix_memalign with equivalent windows functions.
And a few minor fixes, type casts.
This commit was SVN r24429.
- poll() can return POLLRDNORM even if not requested (Solaris bug)
- MIN macro not defined in btl_openib.c
and while we're at it, we clean up the MIN definition in ad_bgl_pset.h
- btl_openib_connect_rdmacm.c was calling rdma_destroy_id() twice
leading to undefined behavior (a hang on Solaris)
This commit was SVN r24356.
code from upper level into btl configure.m4. Changed
prefix from "OMPI" to "BTL" in preprocessor macro. Add
an mca param that shows it has been configured in.
This commit was SVN r24270.
on some systems caused by the definition of malloc in
opal_config_bottom.h getting expanded in the system malloc.h when
OPAL_ENABLE_MEM_DEBUG is set to 1.
This commit was SVN r24210.
verbose statement that shows up when you --mca btl_base_verbose 100.
It clearly states that the openib BTL disqualifies itself when
MPI_THREAD_MULTIPLE is used.

This commit was SVN r24196.
New mca parameter is added (ib_path_rec_service_level) - positive value means that we should get the SL from the SA.
This is usable for torus topologies where different SL value is used for different endpoints.
A cache is kept of ib queue pairs used to communicate with the SA for a particular device and port and path record SL values retrieved from that SA.
The interaction with the cache assumes that there are no recursive calls to these routines. This must be solved either by code flow, by using higher level locks, or by adding a locking mechanism to these routines along with some method for avoiding deadlock.
This code use a UD queue pair to talk to the SA, and not need to chmod /dev/infiniband/umad* for use by normal users.
The request to the SA is a SubnAdmGet(), not a SubnAdmGetTable().
In the future we might add a support of a SubnAdmGetTable(), but it will require implementing RMPP (Reliable Multi-Packet Transaction Protocol) and I'm not sure we want to do that.
This patched is based on the work of David McMillen <davem@systemfabricworks.com>.
This commit was SVN r24195.
The patch includes the following:
* Add new mca parameter - btl_openib_max_hw_msg_size - Maximum size (in bytes) of a single fragment of a long message when using the RDMA protocols (must be > 0 and <= hw capabilities).
* If btl_openib_max_hw_msg_size is larger than the maximum hw limitation print error message.
* Change the default openib flags to include only PUT and not GET.
* Print error message if user choose manually GET flag in openib btl.
* In prepare_dst: limit the message size to be the minimum of both endpoint's hw_limitation and the user limitation (if requested).
This commit was SVN r24191.
If specified, a comma-delimited list of TCP interfaces. Interfaces
will be assigned, one to each MPI process, in a round-robin fashion
on each server. For example, if the list is "eth0,eth1" and four
MPI processes are run on a single server, then local ranks 0 and 2
will use eth0 and local ranks 1 and 3 will use eth1.
This feature is only useful for environments with virtual ethernet
interfaces on the same network. For example, if eth0 and eth1 are
virtual interfaces to the same NIC on the same subnet, and if the NIC
provides different hardware resources to eth0 and eth1 (not just
different kernel resources), some HOL blocking and congestion issues
can be eased in a modest fashion.
This commit was SVN r24181.
Note: the ompi_check_libfca.m4 file had to be modified to avoid it stomping on global CPPFLAGS and the like. The file was also relocated to the ompi/config directory as it pertains solely to an ompi-layer component.
Forgive the mid-day configure change, but I know Shiqing is working the windows issues and don't want to cause him unnecessary redo work.
