Ralph Castain	7c7304466c	Add a binomial tree-based launch to ssh, turned "on" only when the plm_rsh_tree_spawned mca param is set to a non-zero value. This probably isn't a very optimized capability, but it does execute a tree-based launch that may scale better than linear at high node counts. ... Add the daemon map capability to the ODLS to create and save a map of daemon vpid vs nodename from the launch message. Cleanup a few places in the base plm launch support where we didn't adequately protect rml recv's from potentially executing sends. This commit was SVN r18143.	2008-04-14 18:26:08 +00:00
Ralph Castain	3a0d09300b	Fully implement the inbound binomial allgather for daemon-based collectives. Supports both modex and barrier operations. ... Comm_spawn still uses the rank=0 method - shifting that algo to the daemons is under study. This commit was SVN r18115.	2008-04-09 22:10:53 +00:00
Ralph Castain	d70e2e8c2b	Merge the ORTE devel branch into the main trunk. Details of what this means will be circulated separately. ... Remains to be tested to ensure everything came over cleanly, so please continue to withhold commits a little longer This commit was SVN r17632.	2008-02-28 01:57:57 +00:00
Ralph Castain	82a8e2d10d	Reorganize the odls framework to place common functionality in the base, thus making maintenance easier. We still need this to be a framework as some environments (e.g., bproc) require significantly different functionality. However, there is quite a bit of commonality across the components, so this ensures that fixes in one get propagated across the others. ... This patch also fixes a minor bug discovered along the way: we had "lost" the passing of the oversubscribed condition flag from the mapper to the orteds. Thus, we were not setting sched_yield correctly when in oversubscribed conditions (except when a hostfile was specified - different logic there because we treat the number of slots allocated on the node as "uncertain") I did not modify the process component in this patch - I will send a proposed patch to the maintainers of that component so they can review it first.

Ralph Castain	37dfdb76eb	Here is the major MAD-cure commit. I have written plenty about it, so I refer you here to those messages for a description of everything that was done. ... This commit was SVN r11661.	2006-09-14 21:29:51 +00:00
