Ralph Castain f4f2287958 Singletons currently start out by spawning an HNP - this is required solely in the cases where the singleton subsequently calls MPI_Comm_spawn or publishes port info without support from an external orte-server. In all other cases, the HNP is of no value and can actually be a detriment by creating additional overhead on the node. This is particularly concerning for async operations where processes may begin as singletons and then dynamically wireup to perform pt2pt communications. ... So we now allow singletons to start on their own, only spawning an HNP when initiating an operation that actually requires it. cmr:v1.7.4:reviewer=jsquyres This commit was SVN r29354.		2013-10-04 02:58:26 +00:00

Makefile.am	Fix mistake that came in via the ompi-agen tree in r23764. The mistake wasn't part of the core autogen upgrade; it was an additional 'bonus' cleanup. Oops. The mistake will always create a set of directories under installdir, even if you do not --with-devel-headers. The set of directories will be empty, but still -- they should not be there at all. This commit fixes that -- the directories are not created at all if you do not --with-devel-headers	2010-09-24 22:53:28 +00:00
