Abstract: One embodiment provides a method, the method including: identifying, using a cluster management system, a server is physically connected to a network; determining, using the cluster management system, the server needs to be provisioned to a server cluster of the network utilizing cluster information corresponding to the network included within a catalog that is unique to an entity corresponding to the network and includes information related to the network, server clusters of the network, and parameters of the network and the server clusters; and automatically provisioning, using the cluster management system, the server for inclusion in the server cluster using configuration information included within the catalog. Other aspects are claimed and described.

Abstract: Embodiments of the present invention provide a method for reducing load time of a program in a highly-parallelized or distributed computer. In one embodiment, this is accomplished by selectively reusing entries in a page table generated during a previous invocation of the program at a particular compute node of the highly-parallelized or distributed computer system.

Abstract: A method and apparatus improves the block allocation time in a parallel computer system. A pre-load controller pre-loads blocks of hardware in a supercomputer cluster in anticipation of demand from a user application. In the preferred embodiments the pre-load controller determines when to pre-load the compute nodes and the block size to allocate the nodes based on pre-set parameters and previous use of the computer system. Further, in preferred embodiments each block of compute nodes in the parallel computer system has a stored hardware status to indicate whether the block is being pre-loaded, or already has been pre-loaded. In preferred embodiments, the hardware status is stored in a database connected to the computer's control system. In other embodiments, the compute nodes are remote computers in a distributed computer system.

Abstract: A method, apparatus, system, and signal-bearing medium that, in an embodiment, receive a license to a number of resources in a cluster. The licensed resources may be activated and deactivated at any computer system in the cluster, so long as the number of active resources in the cluster is less than or equal to the number of licensed resources to the cluster. In this way, if a resource or a computer system containing resources in the cluster fails, the licensee may still use other licensed resources up to the number of licensed resources.
