Fix a few places where we weren't completely identifying hostfile-based operations against "localhost" entries. Tell the mapper base to be silent when we don't want errors announced because nodes aren't available for mapping (something it is okay if they are fully used). Fix an infinite loop in the file prepositioning code. This commit was SVN r27210.

Sorry for mid-day commit, but I had promised on the call to do this upon my return. Roll in the ORTE state machine. Remove last traces of opal_sos. Remove UTK epoch code. Please see the various emails about the state machine change for details. I'll send something out later with more info on the new arch. This commit was SVN r26242.

Bring the map fixes into the main trunk. This should fix several problems, including the multiple app_context issue. I have tested on rsh, slurm, bproc, and tm. Bproc continues to have a problem (will be asking for help there). Gridengine compiles but I cannot test (believe it likely will run). Poe and xgrid compile to the extent they can without the proper include files. This commit was SVN r12059.

The rest of the multi app_context fix. Remove the restriction on number of app_contexts that can have zero np specified as multiple mappers now support that use-case. Update the ranking algorithms to respect and track bookmarks. Ensure we properly set the oversubscribed flag on a per-node basis. This commit was SVN r25578.

ORTE_DECLSPEC int orte_rmaps_base_compute_vpids(orte_job_t *jdata,
orte_app_context_t *app,
opal_list_t *nodes);
Compute and pass the local_rank and local number of procs (in that proc's job) on the node. To be precise, given this hypothetical launching pattern: host1: vpids 0, 2, 4, 6 host2: vpids 1, 3, 5, 7 The local_rank for these procs would be: host1: vpids 0->local_rank 0, v2->lr1, v4->lr2, v6->lr3 host2: vpids 1->local_rank 0, v3->lr1, v5->lr2, v7->lr3 and the number of local procs on each node would be four. If vpid=0 then does a comm_spawn of one process on host1, the values of the parent job would remain unchanged. The local_rank of the child process would be 0 and its num_local_procs would be 1 since it is in a separate jobid. I have verified this functionality for the rsh case - need to verify that slurm and other cases also get the right values. Some consolidation of common code is probably going to occur in the SDS components to make this simpler and more maintainable in the future. This commit was SVN r14706.

Modify the OMPI paffinity and mapping system to support socket-level mapping and binding. Mostly refactors existing code, with modifications to the odls_default module to support the new capabilities. Adds several new mpirun options: * -bysocket - assign ranks on a node by socket. Effectively load balances the procs assigned to a node across the available sockets. Note that ranks can still be bound to a specific core within the socket, or to the entire socket - the mapping is independent of the binding. * -bind-to-socket - bind each rank to all the cores on the socket to which they are assigned. * -bind-to-core - currently the default behavior (maintained from prior default) * -npersocket N - launch N procs for every socket on a node. Note that this implies we know how many sockets are on a node. Mpirun will determine its local values. These can be overridden by provided values, either via MCA param or in a hostfile Similar features/options are provided at the board level for multi-board nodes. Documentation to follow...

ORTE_DECLSPEC int orte_rmaps_base_compute_local_ranks(orte_job_t *jdata);
At long last, the fabled revision to the affinity system has arrived. A more detailed explanation of how this all works will be presented here: https://svn.open-mpi.org/trac/ompi/wiki/ProcessPlacement The wiki page is incomplete at the moment, but I hope to complete it over the next few days. I will provide updates on the devel list. As the wiki page states, the default and most commonly used options remain unchanged (except as noted below). New, esoteric and complex options have been added, but unless you are a true masochist, you are unlikely to use many of them beyond perhaps an initial curiosity-motivated experimentation. In a nutshell, this commit revamps the map/rank/bind procedure to take into account topology info on the compute nodes. I have, for the most part, preserved the default behaviors, with three notable exceptions: 1. I have at long last bowed my head in submission to the system admin's of managed clusters. For years, they have complained about our default of allowing users to oversubscribe nodes - i.e., to run more processes on a node than allocated slots. Accordingly, I have modified the default behavior: if you are running off of hostfile/dash-host allocated nodes, then the default is to allow oversubscription. If you are running off of RM-allocated nodes, then the default is to NOT allow oversubscription. Flags to override these behaviors are provided, so this only affects the default behavior. 2. both cpus/rank and stride have been removed. The latter was demanded by those who didn't understand the purpose behind it - and I agreed as the users who requested it are no longer using it. The former was removed temporarily pending implementation. 3. vm launch is now the sole method for starting OMPI. It was just too darned hard to maintain multiple launch procedures - maybe someday, provided someone can demonstrate a reason to do so. As Jeff stated, it is impossible to fully test a change of this size. I have tested it on Linux and Mac, covering all the default and simple options, singletons, and comm_spawn. That said, I'm sure others will find problems, so I'll be watching MTT results until this stabilizes. This commit was SVN r25476.

Roll in the Voltaire core/socket/etc process mapping implementation. Only change I made was to cleanup some of the diagnostic output in the odls_default component so it uses the -mca odls_base_verbose parameter. You will not see any impact from this change unless you use the syntax described in ticket #1023. I've tried as many of the RAS components as possible and saw no problem - there may be issues with other RAS components that would not compile on any of my systems. Anything that appears should be trivial to fix. This commit was SVN r15427.
