Next step in reducing launch time: begin reducing the size of the launch message itself. Start by expressing the daemon map as a set of three regular expression strings. On an 8k cluster, this reduces the nidmap contribution from over 200kBytes to 21 bytes in size. Signed-off-by: Ralph Castain <rhc@open-mpi.org>

Fix some major bit-rot on scalable launch. If static ports are provided, then daemons can connect back to the HNP via the routed connection tree instead of doing so directly. In order to do that at scale, the node list must be passed as a regular expression - otherwise, the orted command line gets too long. Over the course of time, usage of static ports got corrupted in several places, the "parent" info got incorrectly reset, etc. So correct all that and get the regex-based wireup going again. Also, don't pass node lists if static ports aren't enabled - they are of no value to the orted and just create the possibility of overly-long cmd lines. This commit was SVN r24860.

Continue development of regular expression support by implementing it for slurm launches. Works for both initial (cmd line and non-cmd line) and comm_spawn launch. Additional work required to fully enable static port support when using cmd line regular expression launch system. This commit was SVN r21502.

Update how we pass the node regex so we pass _all_ nodes, even those without daemons. This allows the backend daemons to form a complete picture of the allocation. Include info on which nodes have daemons on them, and populate that info on the backend as well. Set the daemons' state to "running" and mark them as "alive" by default when constructing the nidmap Get the DVM running again Fix direct modex by eliminating race condition caused by releasing data while sending it Up the size limit before compressing Signed-off-by: Ralph Castain <rhc@open-mpi.org>

Create an alternative mapping method that pushes responsibility onto the backend daemons. By default, let mpirun only pack the app_context info and send that to the backend daemons where the mapping will be done. This significantly reduces the computational time on mpirun as it isn't running up/down the topology tree computing thousands of binding locations, and it reduces the launch message to a very small number of bytes. When running -novm, fall back to the old way of doing things where mpirun computes the entire map and binding, and then sends the full info to the backend daemon. Add a new cmd line option/mca param --fwd-mpirun-port that allows mpirun to dynamically select a port, but then passes that back to all the other daemons so they will use that port as a static port for their own wireup. In this mode, we no longer "phone home" directly to mpirun, but instead use the static port to wireup at daemon start. We then use the routing tree to rollup the initial launch report, and limit the number of open sockets on mpirun's node. Update ras simulator to track the new nidmap code Cleanup some bugs in the nidmap regex code, and enhance the error message for not enough slots to include the host on which the problem is found. Update gadget platform file Initialize the range count when starting a new range Fix the no-np case in managed allocation Ensure DVM node usage gets cleaned up after each job Update scaling.pl script to use --fwd-mpirun-port. Pre-connect the daemon to its parent during launch while we are otherwise waiting for the daemon's children to send their "phone home" rollup messages Signed-off-by: Ralph Castain <rhc@open-mpi.org>
