OPTIMIZING SIMULTANEOUS STARTUP OR MODIFICATION OF INTER-DEPENDENT MACHINES WITH SPECIFIED PRIORITIES

Identify individual machines of a multi-machine computing system. Construct a graph of dependencies among the machines. Obtain estimated total administration times and administration priorities for each of the machines. Identify availability of administration resources to assist in administration of one or more of the machines. Select a first set of machines for administration in response to the graph, administration priorities, estimated total administration times, and availability of the first set of administration resources, and administer the first set of machines in parallel using the first set of administration resources. Update the graph in response to administration of the first set of machines. Select a subsequent set of machines for administration in response to the updated graph, administration priorities, estimated total administration times, and availability of a subsequent set of administration resources. Administer the subsequent set of machines in parallel using the subsequent set of administration resources.
