fceabb2498 Update libevent to the 2.0 series, currently at 2.0.7rc. We will update to their final release when it becomes available. Currently known errors exist in unused portions of the libevent code. This revision passes the IBM test suite on a Linux machine and on a standalone Mac.
This is a fairly intrusive change, but outside of the moving of opal/event to opal/mca/event, the only changes involved (a) changing all calls to opal_event functions to reflect the new framework instead, and (b) ensuring that all opal_event_t objects are properly constructed since they are now true opal_objects.

Note: Shiqing has just returned from vacation and has not yet had a chance to complete the Windows integration. Thus, this commit almost certainly breaks Windows support on the trunk. However, I want this to have a chance to soak for as long as possible before I become less available a week from today (going to be at a class for 5 days, and thus will only be sparingly available) so we can find and fix any problems.

Biggest change is moving the libevent code from opal/event to a new opal/mca/event framework. This was done to make it much easier to update libevent in the future. New versions can be inserted as a new component and tested in parallel with the current version until validated, then we can remove the earlier version if we so choose. This is a statically built framework ala installdirs, so only one component will build at a time. There is no selection logic - the sole compiled component simply loads its function pointers into the opal_event struct.

I have gone thru the code base and converted all the libevent calls I could find. However, I cannot compile nor test every environment. It is therefore quite likely that errors remain in the system. Please keep an eye open for two things:

1. compile-time errors: these will be obvious as calls to the old functions (e.g., opal_evtimer_new) must be replaced by the new framework APIs (e.g., opal_event.evtimer_new)

2. run-time errors: these will likely show up as segfaults due to missing constructors on opal_event_t objects. It appears that it became a typical practice for people to "init" an opal_event_t by simply using memset to zero it out. This will no longer work - you must either OBJ_NEW or OBJ_CONSTRUCT an opal_event_t. I tried to catch these cases, but may have missed some. Believe me, you'll know when you hit it.

There is also the issue of the new libevent "no recursion" behavior. As I described on a recent email, we will have to discuss this and figure out what, if anything, we need to do.

3f7f8df40f Fix singleton comm_spawn by having the host orted create a map object for the singleton job. Even though this isn't filled in, the pidmap function will ignore any job that doesn't have a map object. Thus, this ensures that the singleton's location is included in the pidmap, thereby allowing messages to be routed to/from it.

12cd07c9a9 Start reducing our dependency on the event library by removing at least one instance where we use it to redirect the program counter. Rolf reported occasional hangs of mpirun in very specific circumstances after all daemons were done. A review of MTT results indicates this may have been happening more generally in a small fraction of cases.
The problem was tracked to use of the grpcomm.onesided_barrier to control daemon/mpirun termination. This relied on messaging -and- required that the program counter jump from the errmgr back to grpcomm. On rare occasions, this jump did not occur, causing mpirun to hang.

This patch looks more invasive than it is - most of the affected files simply had one or two lines removed. The essence of the change is:

* pulled the job_complete and quit routines out of orterun and orted_main and put them in a common place

* modified the errmgr to directly call the new routines when termination is detected

* removed the grpcomm.onesided_barrier and its associated RML tag

* add a new "num_routes" API to the routed framework that reports back the number of dependent routes. When route_lost is called, the daemon's list of "children" is checked and adjusted if that route went to a "leaf" in the routing tree

* use connection termination between daemons to track rollup of the daemon tree. Daemons and HNP now terminate once num_routes returns zero

Also picked up in this commit is the addition of a new bool flag to the app_context struct, and increasing the job_control field from 8 to 16 bits. Both trivial.

afbe3e99c6 * Wrap all the direct error-code checks of the form (OMPI_ERR_* == ret) with
(OMPI_ERR_* = OPAL_SOS_GET_ERR_CODE(ret)), since the return value could be a
 SOS-encoded error. The OPAL_SOS_GET_ERR_CODE() takes in a SOS error and returns
 back the native error code.

* Since OPAL_SUCCESS is preserved by SOS, also change all calls of the form
  (OPAL_ERROR == ret) to (OPAL_SUCCESS != ret). We thus avoid having to
  decode 'ret' to get the native error code.

55889934d8 After hours spent chasing the stupid "abort" file, it became clear that we were always going to be plagued by that idiot contraption when trying to be good citizens and properly cleanup. So get rid of it by instead doing a messaging handshake with the local daemon.
Note that this isn't a problem since MPI_Abort and orte_abort are only called under controlled circumstances - i.e., we are doing an orderly abort and not segfaulting. If we can't get the message out for some reason, then too bad - we'll still see an abnormal process termination and act accordingly.

efbb5c9b7c Revamp the errmgr framework to provide a greater range of optional behaviors, including different behaviors for daemons, and remove several looping messages across the code base:
* add hnp and orted modules to the errmgr framework. The HNP module contains much of the code that was in the errmgr base since that code could only be executed by the HNP anyway.

* update the odls to report process states directly into the active errmgr module, thus removing the need to send messages looped back into the odls cmd processor. Let the active errmgr module decide what to do at various states.

* remove the code to track application state progress from the plm_base_launch_support.c code. Update the plm modules to call the errmgr directly when a launch fails.

* update the plm_base_receive.c code to call the errmgr with state updates from remote daemons

* update the routed modules to reflect that process state is updated in the errmgr

* ensure that the orted's open the errmgr and select their appropriate module

* add new pretty-print utilities to print process and job state. Move the pretty-print of time info to a globally-accessible place

* define a global orte_comm function to send messages from orted's to the HNP so that others can overlay the standard RML methods, if desired.

* update the orterun help output to reflect that the "term w/o sync" error message can result from three, not two, scenarios

18c7aaff08 Update the grpcomm framework to be more thread-friendly.
Modify the orte configure options to specify --enable-multicast such that it directs components to build or not instead of littering the code base with #if's. Remove those #if's where they used to occur.

Add a new grpcomm "mcast" module to support multicast operations. Still some work required to properly perform daemon collectives for comm_spawn operations. New module only builds when --enable-multicast is provided, and when specifically selected.

16b100219d A patch from UTK to allow orte_init(), opal_init(), and associated
friends also receive &argc and &argv (George asked Jeff to Ralph to
review before committing).  The thought is that passing argv and argc
to opal/orte_init be useful to other projects outside of OMPI that are
using OPAL and/or ORTE (especially in conjunction with some other
bootstrapping code where it is helpful to modify argv).  It's such a
small thing that it's easy to apply here to make others' lives a
little easier.

Ask George for more details; I'm just the messenger.  :-)

Judging by the copyrights on this patch, it's been around for a
while.  :-)

a0d5c80ce0 Add a new framework for discovering local resource information such as cpu type/model, #cpus, available physical memory, etc. Two initial components (darwin and linux) are provided. This is needed to support bootstrap operations where daemons are started at node boot, and applications where initial knowledge of cpu identification is needed to guide framework component selection.
Add orte configuration option to control the use of the framework in the system. Although the code will build, it will not be active unless configured with --enable-bootstrap.

If bootstrap is enabled and the new opal_sysinfo framework can successfully determine the cpu model, pass that info to the application as an MCA param to support some work at Sun.

Also, have daemons report back the resources they find to guide process mapping in bootstrap operations (i.e., where the daemon starts at node boot as opposed to being launched at application start).

Adjust some platform files to enable these capabilities.

addaf7aaf8 Repair the tree spawn. The problem seems to come from the fact
that now the HNP send the messages using the routed component. In the case
of tree spawn, when a intermediary node spawn a child it doesn't know how
to forward a message to it, so when the node-map message is coming from
the HNP (as there is nothing yet in the contact/routing table) the message
is sent back the way it came. As a result the node-map message keeps jumping
between the HNP and the first level orteds.

The solution is to add a new option to the children orte_parent_uri, which
is only set when the orted is _not_ directly spawned by the HNP. When this
option is present on the argument list, the orted will add the parent to
its routing, and force the parent to update his routes (by sending the URI).
With this approach, the routing tree is build in same time as the processes
are spawned, and all messages from the HNP can be routed to the leaves.

However, this is far from an optimal solution. Right now, this so called tree
spawn, only spawn the children in a tree without doing anything about the
"connect back to the HNP" step. The HNP is flooded with reports from all the
orted. The total number of messages is higher than in the non tree startup
scheme, so we do not expect this approach to be scalable in the current
incarnation. A complete overhaul of the tree startup is required in order
improve the scalability. Stay tuned!

c45ff0d59f Take the next step towards fully utilizing static ports for the daemons to eliminate the initial "phone home" to mpirun by modifying the orted termination procedure to eliminate the need for a full barrier-like operation. Instead, we add a "onesided" barrier to the grpcomm framework API that releases the orted once it has completed its own contribution to the barrier - i.e., the orteds now exit as the "ack" message rolls up towards mpirun instead of sending the "ack" directly to mpirun.
This causes the orteds in the routing tree to remain alive until all termination "acks" from orteds below them have passed through. Thus, if we use static ports, we no longer require a direct orted-to-mpirun connection.

Also modify the binomial routed module so it conforms to what all the other routed modules do and have all messages pass along the routing tree instead of short-circuiting between orteds. This further reduces the number of ports being opened on backend nodes.
