 *
 * The Open RTE Resource Allocation Subsystem (RAS)
 *
 * The resource allocation subsystem is responsible for determining
 * what (if any) resources have been allocated to the specified job
 * (via some prior action), and to obtain an allocation (if possible)
 * if resources have NOT been previously allocated. It is anticipated
 * that ORTE users will execute an "mpirun" or other command that
 * invokes ORTE through one of two channels:
 *
 * 1. the user will login to the computing resource they intend
 * to use, request a resource allocation from that system, and then
 * execute the mpirun or other command. Thus, the allocation has
 * already been obtained prior to ORTE's initialization.  In most
 * cases, systems pass allocation information via environmental
 * parameters.  Thus, the RAS components must know the correct
 * environmental parameter to look for within the environment they
 * seek to support (e.g., an LSF component should know that LSF passes
 * allocation parameters as a specific LSF-named entity).
 *
 * 2. the user issues an mpirun command or an application that uses
 * ORTE without obtaining an allocation in advance. Thus, the associated
 * RAS component must know how to request an allocation from the
 * designated resource. If it doesn't, or it cannot obtain the allocation,
 * then it shall indicate this by setting the system to an appropriate
 * state.
