69de442136 orterun: allow DDT if options contain :'s
There is a bug in MPMD detection that disables totalview if a : is
found anywhere on the command line. This includes inside an argument
option or MCA variable value. This commit changes the check to look
for the string " : " instead of the character : which should eliminate
the issue in most cases.

60a7bc2e50 Enable the PMIx notification callback system. This currently is only supported by the pmix120 component, which is not selected by default. All other components will ignore error registration requests, and thus do not support debugger attach when launched via mpirun. Note that direct launched applications will support such attachment, but may not do so in a scalable fashion.

06c3dfc052 Refactor the ORTE DVM code so that external codes can submit multiple jobs using only a single connection to the HNP.
* Clean up the DVM so it continues to run even when applications error out and we would ordinarily abort the daemons.
* Create a new errmgr component for the DVM to handle the differences.
* Cleanup the DVM state component.
* Add ORTE bindings directory and brief README
* Pass a local tool index around to match jobs.
* Pass the jobid on job completion.
* Fix initialization logic.
* Add framework for python wrapper.
* Fix terminate-with-non-zero-exit behavior so it properly terminates only the indicated procs, notifies orte-submit, and orte-dvm continues executing.
* Add some missing options to orte-dvm
* Fix a bug in -host processing that caused us to ignore the #slots designator. Add a new attribute to indicate "do not expand the DVM" when submitting job spawn requests.
* It actually makes no sense that we treat the termination of all children differently than terminating the children of a specific job - it only creates confusion over the difference in behavior. So terminate children the same way regardless.

Extend the cmd_line utility to easily allow layering of command line definitions

Catch up with ORTE interface change and make build more generic.

Disable "fixed dvm" logic for now.

Add another cmd_line function to merge a table of cmd line options with another one, reporting as errors any duplicate entries. Use this to allow orterun to reuse the orted_submit code

Fix the "fixed_dvm" logic by ensuring we reset num_new_daemons to zero. Also ensure that the nidmap is sent with the first job so the downstream daemons get the node info. Remove a duplicate cmd line entry in orterun.

Revise the DVM startup procedure to pass the nidmap only once, at the startup of the DVM. This reduces the overhead on each job launch and ensures that the nidmap doesn't get overwritten.

Add new commands to get_orted_comm_cmd_str().

Move ORTE command line options to orte_globals.[ch].

Catch up with extra orte_submit_init parameter.

Add example code.

Add documentation.

Bump version.

The nidmap and routing data must be updated prior to propagating the xcast or else the xcast will fail.

Fix the return code so it is something more expected when an error occurs. Ensure we get an error returned to us when we fail to launch for some reason. In this case, we will always get a launch_cb as we did indeed attempt to spawn it. The error code will be returned in the complete_cb.

Fix the return code from orte_submit_job - it was returning the tracker index instead of "success". Take advantage of ORTE's pretty-print capabilities to provide a nice error output explaining why we failed to launch. Ensure we always get a launch_cb when we fail to launch, but no complete_cb as the job never launched.

Extend the error reporting capability to job completion as well.

Add index parameter to orte_submit_job().

Add orte_job_cancel and implement ORTE_DAEMON_TERMINATE_JOB_CMD.

Factor out dvm termination.

Parse the terminate option at tool level.

Add error string for ORTE_ERR_JOB_CANCELLED.

Add some safeguards.

Cleanup and/of comments.

Enable the return.

Properly ORTE_DECLSPEC orte_submit_halt.

Add orte_submit_halt and orte_submit_cancel to interface.

Cleanup the configury so we properly check for Singularity under the various typical use-cases

Bring the Singularity support online. We have to turn "off" the sm BTL as it segfaults from inside the container - root cause remains unclear. Also turned "off" the various OPAL shmem components in case they are involved and someone else tries to use them. Happily, the vader BTL works just fine!

fab1eca536 grpcomm: fix bugs in grpcomm algorithms
This commit fixes multiple issues in the bruck's and recursive
doubling grpcomm algorithms. The following changes are included:

 - Use the existing bitmap implementation instead of implementing a
   new one. There were bugs in the implementation that caused an
   overrun of the bitmap array.

 - Clean up the algorithms to eliminate errors.

 - Send as little extra data as possible in the bruck's
   algorithm.

The changes were testest with various numbers of ortes varying from 1
to 4096.

39367ca0bf plm/alps: only use srun for Native SLURM
Turns out that the way the SLURM plm works
is not compatible with the way MPI processes
on Cray XC obtain RDMA credentials to use
the high speed network.  Unlike with ALPS,
the mpirun process is on the first compute
node in the job.  With the current PLM launch
system, mpirun (HNP daemon) launches the MPI
ranks on that node rather than relying on
srun.

This will probably require a significant amount
of effort to rework to support Native SLURM
on Cray XC's.  As a short term alternative,
have the alps plm (which gets selected by default
again on Cray systems regardless of the launch system)
check whether or not srun or alps is being used on the
system.  If alps is not being used, print a helpful
message for the user and abort the job launch.

03eb1a80bf Update the PMIx native component to release v1.1.1, with addition of one bug-fix commit beyond the official release
Rename the pmix1xx component to pmix111 so it reflects the actual release it includes

Resolve the problem of PMIx being passed a bogus --with-platform argument when configuring the PMIx tarball code. There is no reason we should be passing --with-platform arguments to any internal subdirectory, so just leave that out when constructing the opal_subdir_args variable.

Update the PMIx code and continue attempting to debug direct modex

Fix a problem in the ORTE PMIx server - there was an early intent to optimize the direct modex by fetching data for all procs from the target job on the remote node, instead of fetching the data one proc at a time. However, this was never completely implemented, and so we would hang if we had multiple overlapping requests for data from more than one proc on the node.

22dc05194e Minor cleanup - explicitly NULL the last member of a function pointer module. Should default to that anyway, but this is cosmetically nicer. 2015-10-30 08:19:55 -07:00

267ca8fcd3 Cleanup the PMIx direct modex support. Add an MCA parameter pmix_base_async_modex that will cause the async modex to be used when set to 1. Default it to 0 for now
to continue current default behavior.

Also add an MCA param pmix_base_collect_data to direct that the blocking fence shall return all data to each process. Obviously, this param has no effect if async_
modex is used.

8b5810f7f7 mca/base: add priority output to mca_base_select
The mca_base_select function uses returned priorities to select the
best component/module. This priority may be of use to the caller so
pass that information back in an optional argument. If the priority is
not needed pass NULL.

363f62a506 Fix singleton operations when running under a SLURM allocation. Sadly, SLURM's PMI will return success even if the PMI server isn't actually available. This leads to erroneous selection of pmix and ess components. So add a further requirement (namely, that we see a job_step envar) to the SLURM pmix components along with some modification of ess selection code to avoid the problem 2015-10-17 20:24:03 -07:00
