According to one aspect of the invention, a method and apparatus for a server node is disclosed. This server node consists of one or more processors. The processors are configured to perform server functions as well as switch and router functions including load balancing and fail-over. The server nodes also have a plurality of ports. These ports allow the server nodes to be connected combined to form blocks and networks as well as to provide connection to external networks. When a server node receives a request, it determines whether it can handle the request. If possible, the server node handles the request. If the server node cannot handle the request, it routes the request to a second, neighboring server node.

Server node with interated networking capabilities

A present invention provides a system and method for avoiding memory hazards in a multi-threaded CPU which shares an L-1 data cache. The system includes a CPU and an AACAM. The AACAM is capable of copying memory addresses from the two or more threads being processed by the CPU. The method provides for comparing the AACAM memory address with the active threads to avoid memory hazards by thread switching before the memory hazard occurs.
