Add the ability to forward SIGTSTP (converted to SIGSTOP) and SIGCONT to the a.outs. By default, they are not forwarded and the behavior remains as it has always been. However, if one runs with --mca orte_forward_job_control 1, then mpirun will catch those two signals and forward them to the orteds which will deliver them to the a.outs. We have had requests for this feature. This commit was SVN r20391.

#include "opal/mca/base/mca_base_param.h"
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...

#include "opal/util/output.h"
Modify the paffinity system to handle binding directives that are "soft" - i.e., when someone directs that we bind if the system supports it. This allows community members to distribute OMPI with default MCA param files that direct general binding policies, without having the distributed software fail if the system cannot support those policies. The new options work by adding an ":if-avail" qualifier to the "bind-to-socket" and "bind-to-core" MCA params. If the system does not support this capability, the job will launch anyway. Without the qualifier, the job will abort with an error message indicating that the required functionality is not supported on this system. This commit was SVN r21975.

Indeed, it is absolutely required by orterun as the first time has to be done prior to parsing the command line, which means that the mca values haven't been parsed yet!

Enable co-location of debugger daemons during initial launch and when debugging a running job. Provide support for four MPIR extensions that allow specification of debugger daemon executable, argv for the debugger daemon, whether or not to forward debugger daemon IO, and whether or not debugger daemon will piggy-back on ORTE OOB network. Last is not yet implemented. No change in behavior or operation occurs unless (a) the debugger specifically utilizes the extensions and, for co-locate while running, the user specifically enables the capability via an MCA param. Two of the MPIR extensions supported here are used in a widely-used debugger for a large-scale installation. The other two extensions are new and being utilized in prototype work by several debuggers for possible future release. This commit was SVN r19275.

Cleanly handle the failed start of an orted, or its unexpected failure after start. This commit will allow mpirun to exit cleanly when this occurs, and does a best-effort attempt to cleanup the mess. However, it still has two unresolved issues that need to be eventually addressed: 1. it depends upon the ability of the native environment to alert us that the orted has died/failed to start. I have included that support for SLURM, but other environments need to be done. 2. for some yet-to-be-determined reason, the message that tells the remaining daemons to "die" isn't getting out of the RML, even though no obvious blockage is standing in the way. Work will continue on resolving that problem. For now, the orteds appear to be exiting on their own quite nicely when they see their HNP "lifeline" disappear.

Modify the orte_process_info structure to handle a broader range of process types by replacing the individual booleans with a 32-bit bitmap. Use a set of #define's to define the individual bits, and a set of matching macros to test for them. Update the orte code base to use the macros instead of the booleans. Minor mod to the ompi layer to use the new #define's - just one-line name replacements. This commit was SVN r21144.

Upgrade the node/orted failure detection code to cover all environments. Use the native environment's capabilities where possible - e.g., SLURM detects orted failure and can report it. Elsewhere, use a heartbeat system to detect orted failure - e.g., for TM and rsh. Heart rate is set via mca param. The HNP checks for callback every 2*heartrate, declares orted failure if not seen in last 2*heartrate time. Also detect orted failed-to-start by setting timeout on launch. Currently only used in TM launcher. Neither detection is enabled by default, but are only active if heartrate is set and/or launch timeout is set.

/* whether to tag output */
Roll in the revamped IOF subsystem. Per the devel mailing list email, this is a complete rewrite of the iof framework designed to simplify the code for maintainability, and to support features we had planned to do, but were too difficult to implement in the old code. Specifically, the new code: 1. completely and cleanly separates responsibilities between the HNP, orted, and tool components. 2. removes all wireup messaging during launch and shutdown. 3. maintains flow control for stdin to avoid large-scale consumption of memory by orteds when large input files are forwarded. This is done using an xon/xoff protocol. 4. enables specification of stdin recipients on the mpirun cmd line. Allowed options include rank, "all", or "none". Default is rank 0. 5. creates a new MPI_Info key "ompi_stdin_target" that supports the above options for child jobs. Default is "none". 6. adds a new tool "orte-iof" that can connect to a running mpirun and display the output. Cmd line options allow selection of any combination of stdout, stderr, and stddiag. Default is stdout. 7. adds a new mpirun and orte-iof cmd line option "tag-output" that will tag each line of output with process name and stream ident. For example, "[1,0]<stdout>this is output" This is not intended for the 1.3 release as it is a major change requiring considerable soak time. This commit was SVN r19767.

Per the July technical meeting: Standardize the handling of the orte launch agent option across PLMs. This has been a consistent complaint I have received - each PLM would register its own MCA param to get input on the launch agent for remote nodes (in fact, one or two didn't, but most did). This would then get handled in various and contradictory ways. Some PLMs would accept only a one-word input. Others accepted multi-word args such as "valgrind orted", but then some would error by putting any prefix specified on the cmd line in front of the incorrect argument. For example, while using the rsh launcher, if you specified "valgrind orted" as your launch agent and had "--prefix foo" on you cmd line, you would attempt to execute "ssh foo/valgrind orted" - which obviously wouldn't work. This was all -very- confusing to users, who had to know which PLM was being used so they could even set the right mca param in the first place! And since we don't warn about non-recognized or non-used mca params, half of the time they would wind up not doing what they thought they were telling us to do. To solve this problem, we did the following: 1. removed all mca params from the individual plms for the launch agent 2. added a new mca param "orte_launch_agent" for this purpose. To further simplify for users, this comes with a new cmd line option "--launch-agent" that can take a multi-word string argument. The value of the param defaults to "orted". 3. added a PLM base function that processes the orte_launch_agent value and adds the contents to a provided argv array. This can subsequently be harvested at-will to handle multi-word values 4. modified the PLMs to use this new function. All the PLMs except for the rsh PLM required very minor change - just called the function and moved on. The rsh PLM required much larger changes as - because of the rsh/ssh cmd line limitations - we had to correctly prepend any provided prefix to the correct argv entry. 5. added a new opal_argv_join_range function that allows the caller to "join" argv entries between two specified indices Please let me know of any problems. I tried to make this as clean as possible, but cannot compile all PLMs to ensure all is correct. This commit was SVN r19097.

Establish an MCA param "orte_allocation_required" so that a system can require the user have an RM-provided allocation in order to run. This helps prevent the problem where a user forgets to get an allocation on an RM-managed cluster, and then executes mpirun on the head node - thus causing all of their mpi procs to launch on the head node, usually bringing it to its knees. Since OMPI allows mpirun to default to the local node, and since users want to retain the option to co-locate procs with mpirun, we needed another param to block this error case.

Create new orte_rsh_agent param so users can specify rsh agent from outside of rsh plm, and sym link that to the old plm_rsh_agent and pls_rsh_agent options. Modify the orte-bootproxy to pass prefix for the remote slave to support hetero/hybrid scenarios This commit was SVN r20492.

Provide a "progress meter" for launch that outputs progress as we are launching, especially on large jobs. Also, provide a timeout mechanism so that we cleanly abort if we don't get a response from the next daemon in a specified time. This commit was SVN r21359.

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...

Modify the paffinity system to handle binding directives that are "soft" - i.e., when someone directs that we bind if the system supports it. This allows community members to distribute OMPI with default MCA param files that direct general binding policies, without having the distributed software fail if the system cannot support those policies. The new options work by adding an ":if-avail" qualifier to the "bind-to-socket" and "bind-to-core" MCA params. If the system does not support this capability, the job will launch anyway. Without the qualifier, the job will abort with an error message indicating that the required functionality is not supported on this system. This commit was SVN r21975.

Revise the new binding system slightly: 1. finalize the logic for properly respecting externally assigned bindings. Thanks to Chris Samuel for his help with this. Still needs some acid testing, but appears to now work. 2. remove the double-logic of requiring opal_paffinity_alone AND bind-to-foo. If the user specifies bind-to-foo, trust her and just do it.

ORTE-level MCA params are defined in several places. Ompi_info cannot call orte_init due to an issue with the memory allocator, thus making it impossible for ompi_info to display all of the ORTE-level MCA params. By consolidating them all into one function, ompi_info can call that function and register the desired variables. This also requires, however, that ompi_info call orte_output_init to avoid generating tons of error messages, so make that adjustment too. Fixes ticket #1314 In addition, orte_output has a race condition issue whereby calls to orte_output/verbose can occur prior to either the RML being defined/setup, or the HNP being defined. This latter occurs during the initialization of the orte_process_info structure. In both cases, there is no way orte_output can send the output to the HNP. Hence, the message must be simply output locally. Fixes ticket #1315 This commit was SVN r18524.
