Abstract: A system for dynamically configuring and scheduling input/output (I/O) workloads among processing cores is disclosed. Resources for an application that are related to each other and/or not multicore safe are grouped together into work nodes. When these need to be executed, the work nodes are added to a global queue that is accessible by all of the processing cores. Any processing core that becomes available can pull and process the next available work node through to completion, so that the work associated with that work node software object is all completed by the same core, without requiring additional protections for resources that are not multicore safe. Indexes track the location of both the next work node in the global queue for processing and the next location in the global queue for new work nodes to be added for subsequent processing.

Abstract: A method and apparatus configured to allow independent threads to communicate synchronously through a block of memory accessible to at least two independent threads for bi-directional communication. The method and apparatus simplify the conversion of computer code to a multi-threaded architecture by allowing threads to effectively interact through function calls and data returns.

Abstract: A system identifies one or more devices having faults in a communication loop. The system includes an interface, a decision module, and a connection processor. The interface is configured for sending requests for information to each device of the communication loop and for receiving responses to the requests. The devices may include computer disk drives for use in a storage system. The requests may include Read-Link Status (RLS) commands sent to the computer disk drives. The RLS commands may provide diagnostics of the disk drives connected to the loop. The decision module is communicatively connected to the interface for weighting the responses of each device to identify the devices having the faults. The responses may be weighted based on the relative potential for disrupting operability of the system. The communication loop may include an FC loop that allows communications between a host system and the computer disk drives.
