The present invention is directed to a high speed packet switching network and, in particular to a method and system for minimizing the time to establish a connection between an origin and a destination node. Due to high dynamicity of the traffic on transmission links, it is important to select a routing path according to a fully up-to-date information on all network resources. The simpler approach is to calculate a new path for each new connection request. This solution may be very time consuming because there are as many path selection operations as connection set up operations. On another hand, the calculation of paths based on an exhaustive exploration of the network topology, is a complex operation which may also take an inordinate amount of resources in large networks. Many of connections originated from a network node flow to the same destination network node. It is therefore possible to take a serious benefit in reusing the same already calculated paths for several connections towards the same node. The path calculated at the time the connection is requested is recorded in a Routing Database and updated each time a modification occurs in the network. Furthermore, alternate paths for supporting non-disruptive path switch on failure or preemption, and new paths towards potential destination nodes can be calculated and stored when the connection set up process is idle. These last operations are executed in background with a low processing priority and in absence of connection request.

A file management system for use with a computer system is disclosed. The file management system comprises a real filesystem for accessing files stored on a storage medium and a custom filesystem. The custom filesystem comprises a hierarchical arrangement of links to a subset of files of the real filesystem. In operation, the custom filesystem has processing priority over the real filesystem. As such, the custom filesystem processes requests relating to files of the file subset prior to processing, if any, of the requests by the real filesystem.

The present invention observes the status on the server side from the storage device side, and controls the processing priority in accordance with the server status. The storage device 2 is utilized by numerous servers 1A through 1C. The server 1A and server 1B form a failover cluster. The status detection part 5 judges whether or not an event observed from the server 1A or 1B corresponds to a specified event (link down or the like). In cases where such a specified event is observed, the status detection part 5 detects the occurrence of failover. In accordance with the detection of the occurrence of failover, the priority control part 6 sets the processing priority of the failover destination server at a priority that is higher than the ordinary processing priority. When the preset failover time has elapsed, the priority during failover is returned to the ordinary priority.

A clustered computer system includes multiple computer systems (or nodes) on a network that can become members of a group to work on a particular task. Each node includes a main thread and one or more work threads. The main thread receives messages from other computer systems in the group, and routes messages intended for the work thread to a response queue and a work queue in the work thread, depending on the type of the message. If the message is a response to a currently-executing task, the message is placed in the response queue in the work thread. If the message is a new non-priority task that needs to be processed, the message is routed to the work queue in the work thread. If the message is a priority message, the message is written to both the work queue and the response queue in the work thread. A priority message processing mechanism uses a priority queue defined in the work thread to assure that the priority message is processed the next time the work thread is ready to process a new task, even if the priority message was received after other tasks have been sent to the work queue.

Each instruction thread in a SMT processor is associated with a software assigned base input processing priority. Unless some predefined event or circumstance occurs with an instruction being processed or to be processed, the base input processing priorities of the respective threads are used to determine the interleave frequency between the threads according to some instruction interleave rule. However, upon the occurrence of some predefined event or circumstance in the processor related to a particular instruction thread, the base input processing priority of one or more instruction threads is adjusted to produce one more adjusted priority values. The instruction interleave rule is then enforced according to the adjusted priority value or values together with any base input processing priority values that have not been subject to adjustment.

Algorithms can be classified according to the distribution situation of inter-frame coding modes and are arranged according to processing priority, different types are judged sequentially, possible modes are compared selectively, and the number of modes to be judged is reduced. Early termination judgment is utilized to carry out priority judgment on an SKIP mode, and whether other modes are early termination is judged through threshold value judgment. If threshold value judgment conditions are met, the SKIP mode is directly utilized to code. If the threshold value judgment conditions are not met, an Inter4*4 mode, an Inter 8*8 mode and an Inter 16*16 mode are used as initial modes. A part of macro block modes are removed according to whether rate-distortion cost meets monotony, and accordingly useless block mode search processes are reduced. Compared with a full-mode selection algorithm, the calculating times is reduced by 52.5% to 85.8%, and the calculating complexity of inter-frame forecasting modules is reduced.
