Abstract

A method, apparatus, system, and signal-bearing medium that, in an embodiment, send a broadcast message to a cluster of servers receive a point-to-point message from a coordinating server of the cluster, where the coordinating server joined the cluster before all other servers in the cluster. The point-to-point message includes routing data regarding all of the servers in the cluster. In an embodiment, the broadcast message includes a record that includes an identification of a new server, resource data regarding the new server, and a time that the new server joins the cluster, and the servers in the cluster add the record to the routing data and send a request to the new server via the record. In another embodiment, the broadcast message includes records for all servers in a second cluster, and the new server sends the routing data to the servers in the second cluster. If a server leaves the cluster, its record is removed. In this way, a cluster can respond to servers dynamically joining and leaving the cluster while reducing network traffic.

Description

technical field [0001] Embodiments of the invention generally involve computers. In particular, embodiments of the invention generally relate to clusters of computer systems connected via a network. Background technique [0002] The development of the EDVAC computer system in 1948 is often cited as the beginning of the computer age. Since then, computer systems have grown into very complex devices, and computer systems can have many different setups. A computer system usually consists of a combination of hardware, such as semiconductors and circuit boards, and software, also known as a computer program. As advances in semiconductor processing and computer architecture drive higher performance computer hardware, more sophisticated and complex computer software has been developed to take advantage of the higher performance of the hardware, resulting in computer systems that are far more powerful than those of just a few years ago many of today's computer systems.
