5.2 Node Allocation While job prioritization allows a site to determine which job to run, node allocation policies allow a site to specify how available resources should be allocated to each job. The algorithm used is specified by the parameter NODEALLOCATIONPOLICY. There are multiple node allocation policies to choose from allowing selection based on reservation constraints, node configuration, available resource constraints, and other issues. The following algorithms are available and described in detail below: FIRSTAVAILABLE, LASTAVAILABLE, MACHINEPRIO, CPULOAD, MINRESOURCE, CONTIGUOUS, MAXBALANCE, FASTEST, and LOCAL. Additional load allocation polices such as may be enabled through extension libraries such as G2. Documentation for the extension library of interest should be consulted. 5.2.1 Node Allocation Overview 5.2.2 Resource Based Algorithms 5.2.2.1 CPULOAD 5.2.2.2 FIRSTAVAILABLE 5.2.2.3 LASTAVAILABLE 5.2.2.4 MACHINEPRIO 5.2.2.5 MINRESOURCE 5.2.2.6 CONTIGUOUS 5.2.2.7 MAXBALANCE 5.2.2.8 FASTEST 5.2.2.9 LOCAL 5.2.3 Time Based Algorithms 5.2.4 Locally Defined Algorithms
