Abstract: A cluster management system and method for synchronizing content libraries within a distributed computer system allows an on-demand synchronization option of a content library subscribed to a publishing content library, which includes at least a consumable software item and metadata of the consumable software item, to be enabled. As a result of the on-demand synchronization option of the subscribed content library being enabled, the metadata of the consumable software item is downloaded from the publishing content library to the subscribed content library without downloading the consumable software item. The consumable software item is downloaded from the publishing content library to the subscribed content library in response to user selection of the consumable software item at the subscribed content library.

Abstract: A large melting furnace suitable for borosilicate glass. The melting furnace includes a melting area, a reinforcing area, an ascending area and a clarifying area. The melting area includes no furnace crown, a surface of molten glass in the melting area is not covered by any wall and exposed for feeding. The reinforcing area includes a first furnace crown, the first furnace crown includes a first partition wall and a second partition wall, and the reinforcing area and the melting area are separated by the first partition wall, and a lower end of the first partition wall goes deep below a surface of molten glass but is not in contact with a bottom of the melting furnace, so as to guarantee that the molten glass in the melting area and the reinforcing area is interconnected.

Abstract: A cluster management system and method for synchronizing content libraries within a distributed computer system uses multiple replication processes to synchronize a subscribed content library with a publishing content library, which includes at least a consumable software item and metadata of the consumable software item. If the consumable software item of the publishing content library can be replicated at the subscribed content library using a first data replication process, then the consumable software item of the publishing content library is replicated at the subscribed content library using the first data replication process. If the consumable software item of the publishing content library cannot be replicated at the subscribed content library using the first data replication process, the consumable software item of the publishing content library is replicated at the subscribed content library using a second data replication process.

Abstract: A coordinated multi-cast content distribution process is used to distribute content, e.g., files, from a source node of a network to target nodes of the network. A minimum spanning tree is identified for the network based on costs of edges connecting the nodes. The minimum spanning tree includes the source node and all target nodes; the minimum spanning tree distinguishes leaf target nodes from non-leaf target nodes. Content parts are moved along the spanning tree in an iterative process in which, for each iteration, the highest-cost leaf nodes are identified and content parts are moved toward the identified leaf nodes. This process reduces avoids network congestion and reduces the total bandwidth consumption required to supply the content to all target nodes.

Abstract: A large melting furnace suitable for borosilicate glass. Which has a melting area, a reinforcing area, an ascending area and a clarifying area. The melting area and the reinforcing area are separated by a partition wall, and a lower end of the partition wall goes deep below a surface of molten glass but is not in contact with a bottom of the melting furnace, so as to guarantee that the molten glass in the two areas is interconnected. The structures of the melting area and reinforcing area can also improve the problem of boron volatilization of the borosilicate glass caused by flame melting during a melting process. The molten glass flows out from a throat of the reinforcing area, passes through the ascending area and enters the shallower clarifying area.
