Ralph Castain 3f04d50cb0 Per the ticket, resolve our handling of overload conditions to provide a more consistent response. If we are overloaded (i.e., attempting to bind more processes to a location than the number of cpus under that location), then we consider the following conditions:
(a) default binding policy is in effect. In this case, we will emit a
warning and default to not binding unless the user provided the
"oversubscribe" or "overload" modifier to the "bind-to" option.

(b) user-specified binding policy is in effect. In this case, we will
error out unless the user provided the "oversubscribe" or "overload"
modifier to the "bind-to" option as we cannot meet the directive.

Either "bind-to" modifier (oversubscribe or overload) will be accepted for
now - in 1.9, we will deprecate the "overload" term in favor of
"oversubscribe".

Also added the ability to accept a --bind-to modifier without specifying the binding policy itself so a user can specify overload-allowed with the default policy.

Closes trac:4345

event Revert r31765 as it causes segfaults in all orte tools. We aren't getting all the events off of the event base in those tools prior to opal calling event_base_free, and that means there are stale memory references that libevent is trying to release. 2014-05-15 14:02:16 +00:00

sec Turns out that valgrind has issues with strings that don't fall on nice 4-byte alignments with some optimized builds. So make the default security credential a nice 7-characters (so we get 8-bytes with the NULL terminator) to make valgrind shut up. 2014-05-22 00:36:25 +00:00
