Ralph Castain bae5dab916 If (and only if) a user requests, set the default number of slots on any node to the number of objects of the specified type. This *only* takes effect in an unmanaged environment - i.e., if an external resource manager assigns us a number of slots, then that is what we use. However, if we are using a hostfile, then the user may or may not have given us a value for the number of slots on each node.
For those nodes (and *only* those nodes) where the user does *not* specify a slot count, we will set the number of slots according to their direction: either to the number of cores, numas, sockets, or hwthreads. Otherwise, the slot count is set to 1.

Note that the default behavior remains unchanged: in the absence of any value for #slots, and in the absence of any directive to set #slots, we will set #slots=1.

This commit was SVN r27236.

help-ras-base.txt At long last, the fabled revision to the affinity system has arrived. A more detailed explanation of how this all works will be presented here: 2011-11-15 03:40:11 +00:00
Makefile.am Establish an MCA param "orte_allocation_required" so that a system can require the user have an RM-provided allocation in order to run. This helps prevent the problem where a user forgets to get an allocation on an RM-managed cluster, and then executes mpirun on the head node - thus causing all of their mpi procs to launch on the head node, usually bringing it to its knees. 2008-08-04 14:25:19 +00:00

ras_base_close.c Complete implementation of the --without-rte-support configure option. Working with Brian, this has been tested on RedStorm. 2008-06-18 03:15:56 +00:00
ras_base_node.c Fix a few places where we weren't completely identifying hostfile-based operations against "localhost" entries. Tell the mapper base to be silent when we don't want errors announced because nodes aren't available for mapping (something it is okay if they are fully used). Fix an infinite loop in the file prepositioning code. 2012-08-31 21:28:49 +00:00

ras_private.h Sorry for mid-day commit, but I had promised on the call to do this upon my return. 2012-04-06 14:23:13 +00:00
