摘要:
Improved techniques are disclosed for processing transactions or requests in a data processing system. For example, a method for processing requests in a system including a plurality of nodes includes the following steps. At least two nodes of the plurality of nodes receive a plurality of requests. The two nodes exchange information to determine an order for processing requests. The two nodes process the requests in accordance with the order. The order may include a total order or a partial order.

Automated techniques are disclosed for coordinating request or transaction processing in a data processing system. For example, a technique for handling requests in a data processing system comprises the following steps. A compound request comprising at least two individual requests of different types is received. An individual request r1 of the compound request is placed on a queue for requests of type t1, wherein t1 is the request type of r1. After r1 has reached the front of the queue, it is determined if at least one individual request of said compound request can execute. The compound request is executed if it is determined that all individual requests of the compound request can execute.

Automated techniques are disclosed for coordinating request or transaction processing in a data processing system. For example, a technique for handling compound requests, in a system comprising multiple nodes for executing requests in which an individual request is associated with a particular node, comprises the following steps. A compound request comprising at least two individual requests associated with a same node is received. It is determined if both of the at least two individual requests are executable. The compound request is executed if it is determined that all individual requests of the compound request can execute.

Automated techniques are disclosed for minimizing communication between nodes in a system comprising multiple nodes for executing requests in which a request type is associated with a particular node. For example, a technique comprises the following steps. Information is maintained about frequencies of compound requests received and individual requests comprising the compound requests. For a plurality of request types which frequently occur in a compound request, the plurality of request types is associated to a same node.As another example, a technique for minimizing communication between nodes, in a system comprising multiple nodes for executing a plurality of applications, comprises the steps of maintaining information about an amount of communication between said applications, and using said information to place said applications on said nodes to minimize communication among said nodes.

摘要:
Techniques are disclosed for processing requests in a data processing system. While the principles of the invention are not limited to a particular domain, they are particularly suitable for use in an electronic trading system. By way of example of one aspect of the invention, a method for directing requests to at least one node in a system comprising multiple nodes and a plurality of requests comprises associating a number to each request, assigning at least one number to each node so as to balance a load across the nodes, and sending a request to a node based on the number associated to the request. Various other aspects are disclosed.
摘要:
A technique for delivering content in a client-server system based on a request received at a computing device from a client includes determining a current load on a next-level computing device of a hierarchy. When this current load is such that a response time for delivery of the request from the next-level computing device would increase above a given threshold, a client type associated with the request is checked and, when the client type indicates that the client is below a given priority level, content to be delivered to the client in response to the request is personalized at the receiving computing device. When the current load is such that the response time would not increase above a given threshold, the request is sent from the receiving computing device to the next-level computing device and the content to be delivered is personalized at the next-level computing device.
