Ralph Castain 90107f3c14 Fix an issue with comm_spawn over who sent/recv first in the modex. The modex assumes that the first name on the list is the "root" that will serve as the allgather collector/distributor. The dpm was putting that entity last, which forced us to pre-inform the parent procs of the child proc's contact info since the parent was trying to send to the child. ...

Clarify the setting of send_first in the mpi bindings (trivial, i know, but helpful)

Remove the extra xcast of child contact info to the parent job.

This commit was SVN r17952.

errmgr

Bring some sanity to the exit code returned by mpirun. Ensure that we provide a non-zero code if something goes wrong, including someone exiting after calling mpi_init without calling mpi_finalize.

ess

Remove the obsolete and largely unused orte_system_info structure. The only fields that were used in that struct were nodeid and nodename - these have been transferred to the orte_process_info structure.

grpcomm

Fix the allgather and allgather_list functions to avoid deadlocks at large node/proc counts. Violated the RML rules here - we received the allgather buffer and then did an xcast, which causes a send to go out, and is then subsequently received by the sender. This fix breaks that pattern by forcing the recv to complete outside of the function itself - thus, the allgather and allgather_list always complete their recvs before returning or sending.

Remove the orte_proc_table. Migrate all users of it to the opal_hash_table and a new name hash function in orte.

Revert that! Need to complete the rest of the change so the orted knows the correct nodeid...
