|
|
* 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.
