| * job_test - Given a specification of scheduling requirements, |

| * "best" is defined as either a minimal number of consecutive nodes |
| * or if sharing resources then sharing them with a job of similar size. |
| * IN/OUT job_ptr - pointer to job being considered for initiation, |
| * set's start_time when job expected to start |
| * IN/OUT bitmap - usable nodes are set on input, nodes not required to |
| * satisfy the request are cleared, other left set |
| * IN min_nodes - minimum count of nodes |
| * IN req_nodes - requested (or desired) count of nodes |
| * IN max_nodes - maximum count of nodes (0==don't care) |
| * IN mode - SELECT_MODE_RUN_NOW (0): try to schedule job now |
| * SELECT_MODE_TEST_ONLY (1): test if job can ever run |
| * SELECT_MODE_WILL_RUN (2): determine when and where job can run |
| * IN preemptee_candidates - list of pointers to jobs which can be preempted. |
| * IN/OUT preemptee_job_list - Pointer to list of job pointers. These are the |
| * jobs to be preempted to initiate the pending job. Not set |
| * if mode=SELECT_MODE_TEST_ONLY or input pointer is NULL. |
| * IN resv_exc_ptr - Various TRES which the job can NOT use. |
| * IN will_run_ptr - Pointer to data specific to WILL_RUN mode |
| * RET zero on success, EINVAL otherwise |
| * globals (passed via select_p_node_init): |
| * node_record_count - count of nodes configured |
| * node_record_table_ptr - pointer to global node table |
| * NOTE: the job information that is considered for scheduling includes: |
| * req_node_bitmap: bitmap of specific nodes required by the job |
| * contiguous: allocated nodes must be sequentially located |
| * num_cpus: minimum number of processors required by the job |
| * NOTE: bitmap must be a superset of req_nodes at the time that |
| * select_p_job_test is called |
