Abstract: A memory system comprising memory modules including memory chips stacked with switching circuits. A memory controller coupled to the memory modules is configured to initiate memory accesses. When a stacked switching circuit detects the memory access, the switching circuit routes the access to another memory module if the access is not directed to a memory chip of the receiving memory module, or processes the access locally if the access is directed to a memory chip of the receiving memory module. The memory controller and memory modules are coupled via bi-directional serial links. Each memory module may include multiple stacked switching circuits, each of which may be coupled to fewer than all of the memory chips within the memory module. Switching circuits further include circuitry configured to de-serialize data prior to conveyance to a memory chip, and serialize data received from a DRAM chip prior to transmitting the received data.

Abstract: A method and mechanism for enabling access to a protected register in a client. A system including multiple clients, such as components and devices, is coupled to a service processor which is configured to manage the system. Clients which are managed by the service processor include control and status registers which are protected from access by unauthorized entities. Access rights for particular registers may be restricted to only the service processor. Clients include a timer which the service processor periodically updates. In the event communication is lost between the service processor and a client, the timer is not updated. In response to detecting the timer was not updated, the client is configured to alter the access rights of the register in order to permit an alternate entity to access the protected register. The service processor may then utilize the alternate entity as a proxy in order to transfer the client state to another client and configure the affected client out of the system.

Abstract: A method and system for dynamically generating web based user interfaces. In one embodiment, a method is disclosed for displaying a user interface over a network to a user. The method begins by reading an HTTP request for authentication from a browser associated with the user. The HTTP request comprises credential information associated with the user. Based on the credential information, a first plug-in module from a plurality of plug-in modules is invoked to authenticate the user. Also, each of the plurality of plug-in modules provide similar authentication services. An authentication user interface is dynamically generated based on the HTTP request and configuration properties that are defined by the first plug-in module.

Abstract: An approach which enables the overhead of performing a task associated with performing a procedure (function) call to be shifted to clients from a reverse proxy server when the reverse proxy server forwards web pages, the content of which may be dynamically created on the clients according to a description (e.g., using Java Script Language). The reverse proxy server may include instructions associated with the description to re-define the procedure call such that the task (in addition to the logic of the pre-defined procedure call) is performed on the clients. For example, with reference to a procedure call containing a URL accessible only within an intranet, the reverse proxy server may insert instructions which cause each client to insert the URL of the reverse proxy server such that any requests for a resource (corresponding to the URL) are passed through the reverse proxy server.

Abstract: A method enables access of a plurality of data sources by a single access operation where each data source in the plurality of data sources requires a different driver to access the data source so that there is a plurality of different drivers. The method includes using an application programming interface (API) for each driver in the plurality of different drivers. The API is substantially identical for each of the drivers in the plurality of different drivers. A merging driver receives the single access operation, and in response to the single access operation, the merging driver accesses the plurality of different drivers through the API.

Abstract: A method of utilizing transport protocols to provide bidirectional web procedure calls is disclosed. A callback request included with a web procedure call provides a destination address and port on the requesting device to be utilized in a new connection for receiving the response from the receiving device. The utilization of a callback request included with a web procedure call enables a receiving device to terminate the original connection upon which it received the web procedure call while performing the requested procedure. In situations where the requested procedure takes an extended period of time or the receiving device is responding to a large number of requests, the ability to drop the original connection, perform the procedure, and respond to the requesting device via a new connection saves resources on the receiving device. Replies to the request are sent to the requesting device utilizing the destination address and port included as a parameter in the callback request.

Abstract: A method and apparatus for enqueuing and dequeuing packets to and from a shared packet memory, while avoiding collisions. An enqueue process or state machine enqueues packets for a communication connection (e.g., channel, queue pair, flow). A dequeue process or state machine operating in parallel dequeues packets and forwards them (e.g., to an InfiniBand node). Packets are stored in the shared packet memory, and status/control information is stored in a control memory that is updated for each packet enqueue and packet dequeue. Prior to updating the packet and/or control memory, each process interfaces with the other to determine if the other process is active and/or to identify the other process' current communication connection. If the enqueue process detects a collision, it pauses (e.g., for a predetermined number of clock cycles). If the dequeue process detects a collision, it selects a different communication connection to dequeue.
