Ralph Castain 897744cdeb Two major changes to the runtime: ... 1. implement and enable the non-described buffer operations. I will send out a more detailed explanation separately. However, this mode of operation (which is now the default) significantly reduces message size during startup. If you want the described buffers, set the mca param "-mca dss_describe_buffer 1". 2. revise the xcast system to support both linear and binomial tree broadcast methods. Since we are seeing scenarios where the binomiall tree can cause problems, I have made the linear method the default. To run with the binomial tree, set the mca param "-mca oob_xcast_mode binomial". 3. add some detailed timing reports to the xcast operation. These are enabled via "-mca oob_xcast_timing 1". 4. add some more unit tests for the dss and gpr (focused on support for the non-described buffer) This commit was SVN r12722.		2006-12-01 22:30:39 +00:00

ns	Bring over the update to terminate orteds that are generated by a dynamic spawn such as comm_spawn. This introduces the concept of a job "family" - i.e., jobs that have a parent/child relationship. Comm_spawn'ed jobs have a parent (the one that spawned them). We track that relationship throughout the lineage - i.e., if a comm_spawned job in turn calls comm_spawn, then it has a parent (the one that spawned it) and a "root" job (the original job that started things).	2006-11-14 19:34:59 +00:00
