e3105a85be Don't require a progress function from the PML. If there is one then the
PML base will take care of the registration with the event library.
Otherwise, (and this apply for the CM case) the MTL are in charge of
registering their own progress function.

62ade993ca Seperate finalize and close for the PML, this gives the PML a chance to complete any outstanding operations prior to close. Before this change we just called pml_finalize in pml_close which causes problems if there are outstanding events that a BTL/MTL needs to progress during finalize. The problem is that MPI_COMM_WORLD and others were destroyed prior to closing the PML, pml_close would call pml_finalize, events would progress in the BTL, and these events expected MPI_COMM_WORLD to still be around..

fd51d9cf28 The call to opal_list_insert() had an off by one error (I think), causing selected components to get lost with certain load orderings.
I went ahead and rewrote the code to use opal_list_insert_pos() instead, which gives a cleaner flow and more speed.

7437f37e96 This commit contains the following:
* Fix some missing includes in a few places.
 * Add the cr_request() functionality to the BLCR CRS component.
   We are now dependent upon the 0.6.* series of BLCR.
 * Made the CR notification mechanism a registered function.
   This way we can have an OPAL-only version and it can be replaced at
   runtime with the ORTE version.
 * Add a 'opal_cr_allow_opal_only' parameter that will enable OPAL-only
   CR functionality when the user wants it. Default: Disabled.
 * Fix the placement of a checkpoint request check in MPI_Init
 * Pull the OPAL notification mechanism into the SnapC framework.
   * We no longer fork/exec the 'opal-checkpoint' command for local
   checkpointing, the Local coordinator in the orted does this directly.
   * The Local and Application coordinator talk together bypassing the OPAL
   notifiation mechanism.
   * Optimized the Local <-> App Coordinator communication.
   * Improved the structure used to track vpid_snapshots in the local coord.
 * Fix a race condition in which an application under heavy communication load
   may produce an inconsistent global checkpoint.

f92d9097d8 Some more changes to update to coll v1.1.0 that were missed
yesterday.  This actually exposed a very, very long-standing bug where
part of the coll base was incorrectly checking the coll API version
against the MCA API version.  When coll went to v1.1 (yesterday) and
was no longer the same as the MCA v1.0, the test started failing.

This commit fixes to check for v1.1 everywhere in the coll base, and
to ensure to check coll framework/API version numbers against coll
framework/API version numbers (vs. against the MCA API version
number).

54b2cf747e These changes were mostly captured in a prior RFC (except for #2 below) and are aimed specifically at improving startup performance and setting up the remaining modifications described in that RFC.
The commit has been tested for C/R and Cray operations, and on Odin (SLURM, rsh) and RoadRunner (TM). I tried to update all environments, but obviously could not test them. I know that Windows needs some work, and have highlighted what is know to be needed in the odls process component.

This represents a lot of work by Brian, Tim P, Josh, and myself, with much advice from Jeff and others. For posterity, I have appended a copy of the email describing the work that was done:

As we have repeatedly noted, the modex operation in MPI_Init is the single greatest consumer of time during startup. To-date, we have executed that operation as an ORTE stage gate that held the process until a startup message containing all required modex (and OOB contact info - see #3 below) info could be sent to it. Each process would send its data to the HNP's registry, which assembled and sent the message when all processes had reported in.

In addition, ORTE had taken responsibility for monitoring process status as it progressed through a series of "stage gates". The process reported its status at each gate, and ORTE would then send a "release" message once all procs had reported in.

The incoming changes revamp these procedures in three ways:

1. eliminating the ORTE stage gate system and cleanly delineating responsibility between the OMPI and ORTE layers for MPI init/finalize. The modex stage gate (STG1) has been replaced by a collective operation in the modex itself that performs an allgather on the required modex info. The allgather is implemented using the orte_grpcomm framework since the BTL's are not active at that point. At the moment, the grpcomm framework only has a "basic" component analogous to OMPI's "basic" coll framework - I would recommend that the MPI team create additional, more advanced components to improve performance of this step.

The other stage gates have been replaced by orte_grpcomm barrier functions. We tried to use MPI barriers instead (since the BTL's are active at that point), but - as we discussed on the telecon - these are not currently true barriers so the job would hang when we fell through while messages were still in process. Note that the grpcomm barrier doesn't actually resolve that problem, but Brian has pointed out that we are unlikely to ever see it violated. Again, you might want to spend a little time on an advanced barrier algorithm as the one in "basic" is very simplistic.

Summarizing this change: ORTE no longer tracks process state nor has direct responsibility for synchronizing jobs. This is now done via collective operations within the MPI layer, albeit using ORTE collective communication services. I -strongly- urge the MPI team to implement advanced collective algorithms to improve the performance of this critical procedure.


2. reducing the volume of data exchanged during modex. Data in the modex consisted of the process name, the name of the node where that process is located (expressed as a string), plus a string representation of all contact info. The nodename was required in order for the modex to determine if the process was local or not - in addition, some people like to have it to print pretty error messages when a connection failed.

The size of this data has been reduced in three ways:

(a) reducing the size of the process name itself. The process name consisted of two 32-bit fields for the jobid and vpid. This is far larger than any current system, or system likely to exist in the near future, can support. Accordingly, the default size of these fields has been reduced to 16-bits, which means you can have 32k procs in each of 32k jobs. Since the daemons must have a vpid, and we require one daemon/node, this also restricts the default configuration to 32k nodes.

To support any future "mega-clusters", a configuration option --enable-jumbo-apps has been added. This option increases the jobid and vpid field sizes to 32-bits. Someday, if necessary, someone can add yet another option to increase them to 64-bits, I suppose.

(b) replacing the string nodename with an integer nodeid. Since we have one daemon/node, the nodeid corresponds to the local daemon's vpid. This replaces an often lengthy string with only 2 (or at most 4) bytes, a substantial reduction.

(c) when the mca param requesting that nodenames be sent to support pretty error messages, a second mca param is now used to request FQDN - otherwise, the domain name is stripped (by default) from the message to save space. If someone wants to combine those into a single param somehow (perhaps with an argument?), they are welcome to do so - I didn't want to alter what people are already using.

While these may seem like small savings, they actually amount to a significant impact when aggregated across the entire modex operation. Since every proc must receive the modex data regardless of the collective used to send it, just reducing the size of the process name removes nearly 400MBytes of communication from a 32k proc job (admittedly, much of this comm may occur in parallel). So it does add up pretty quickly.


3. routing RML messages to reduce connections. The default messaging system remains point-to-point - i.e., each proc opens a socket to every proc it communicates with and sends its messages directly. A new option uses the orteds as routers - i.e., each proc only opens a single socket to its local orted. All messages are sent from the proc to the orted, which forwards the message to the orted on the node where the intended recipient proc is located - that orted then forwards the message to its local proc (the recipient). This greatly reduces the connection storm we have encountered during startup.

It also has the benefit of removing the sharing of every proc's OOB contact with every other proc. The orted routing tables are populated during launch since every orted gets a map of where every proc is being placed. Each proc, therefore, only needs to know the contact info for its local daemon, which is passed in via the environment when the proc is fork/exec'd by the daemon. This alone removes ~50 bytes/process of communication that was in the current STG1 startup message - so for our 32k proc job, this saves us roughly 32k*50 = 1.6MBytes sent to 32k procs = 51GBytes of messaging.

Note that you can use the new routing method by specifying -mca routed tree - if you so desire. This mode will become the default at some point in the future.


There are a few minor additional changes in the commit that I'll just note in passing:

* propagation of command line mca params to the orteds - fixes ticket #1073. See note there for details.

* requiring of "finalize" prior to "exit" for MPI procs - fixes ticket #1144. See note there for details.

* cleanup of some stale header files

d2ef0d445a Add some basic timing hooks so I can extract a few more detailed performance
numbers for tuning.

Switch the bookmark_recv to be non-blocking. If this is blocking then for
process counts >= 32 slight process delays were causing cascading performance
delays in the protocol. This lead to checkpoints either taking about 3 sec or
45 sec (or more) for 64 procs due to the cascading delays. With the nonblocking
receive version this is no longer the case we get the speedup we expect for this
part of the protocol.

58a018c16d The code tries to prevent itself from running for more then one communicator
simultaneously, but is doing it incorrectly. If the function is running already
for one communicator and it is called from another thread for other communicator
with lower cid the check comm->c_contextid != ompi_comm_lowest_cid()
will fail and the function will be executed for two different communicators by
two threads simultaneously. There is nothing in the algorithm that prevent it
from been running simultaneously for different communicators as far as I can see,
but ompi_comm_unregister_cid() assumes that it is always called for a communicator
with the lowest cid and this is not always the case. This patch removes bogus
lowest cid check and fix ompi_comm_register_cid() to properly remove cid from
the list.

3d7b5b306f Fix a problem with OPAL_ALIGN that causes the upper bytes to get chopped

message queues not showing up when debugging a 64 bit app on a 32 bit

bc34a46969 * complete the fix started in r15915, that is, to prevent negative tags
from showing up in the message queue graph. Tags are now casted to int
  before the negative checks, since tags by the spec are stored as 
  mqs_tword_t, an unsigned long long.

59b22533f2 Enable RDMA for heterogeneous situations. Currently done by overloading
the ompi_convertor_need_buffers function to only return 0 if the convertor
is homogeneous (which it never does on the trunk, but does to on v1.2, but
that's a different issue).  Only enable the heterogeneous rdma code for
a btl if it supports it (via a flag), as some btls need some work for this
to work properly.  Currently only TCP and OpenIB extensively tested
