Turns out, this isn't necessarily true. The Cray, for example, launches processes in a toroidal pattern, thus causing the daemons to wind up somewhere other than what we thought. Other environments (e.g., slurm) are also capable of such behavior, depending upon the default mapping algorithm they are told to use. Resolve this problem by making the daemon-to-node assignment in the affected environments when the daemon calls back and tells us what node it is on. Order the nodes in the mapping list so they are in daemon-vpid order as opposed to the order in which they show in the allocation. For environments that don't exhibit this mapping behavior (e.g., rsh), this won't have any impact. Also, clean up the vm launch procedure a little bit so it more closely aligns with the state machine implementation that is coming, and remove some lingering "slave" code. This commit was SVN r25551.

|
|
* The Open RTE Resource MAPping Subsystem (RMAPS)
|
|
*
|
|
* The resource mapping subsystem is responsible for mapping processes
|
|
* to specific nodes/cpus within a given job. In many systems, this
|
|
* functionality will not be supported - the system will map processes
|
|
* wherever it chooses and does not allow the user to specify the
|
|
* mapping. RMAPS components, therefore, provide services for those
|
|
* systems that do permit such mappings.
|
|
*
|
|
* RMAPS checks the MCA parameters to see if a mapping algorithm has
|
|
* been specified. If the user selected a mapping algorithm, the
|
|
* indicated RMAPS component will take information from the registry
|
|
* to determine the number of applications/processes to be run, and
|
|
* the identified resources that have been allocated to this job. The
|
|
* selected RMAP component will then assign processes to resources
|
|
* according to its algorithm, with the results stored on the
|
|
* appropriate job segment - the assigned nodename for each process is
|
|
* stored in that respective process' container on the segment.
