International Classification:

G06F 9/44

US Classification:

717114, 717116

Abstract:

A method is provided, the method comprising defining an actual size of each variable in a programming language at a declaration time when the actual size of the respective variable can be defined and declaring at least one variable in the programming language to have a dynamic size at the declaration time when the actual size of the at least one variable is not known. The method also comprises defining the actual size of the at least one variable in the programming language when the actual size of the at least one variable becomes known after the declaration time.

International Classification:

G06F 13/00
G06F 12/00

US Classification:

711156, 711100, 711154, 709223

Abstract:

A method for faster handling of state change notifications in a storage network such as storage area network (SAN). The method includes receiving a state change notification at a host. The notification is processed to identify a target device affected by a state change. The method includes cleaning an input/output (I/O) resource of the host of I/O operations associated with the target device. A new session request is transmitted from the host to the target device, such as the next communication from the host after receipt of the notification. The cleaning of the host's I/O resources may include killing or abandoning pending I/O operations related to the target device and may also include halting or stopping additional or future I/O operations to the target device. The method includes operating the affected target device to acknowledge the new session request and initiate a new session that includes refreshing target I/O resources.

International Classification:

G06F 3/00

US Classification:

710 8, 710 3, 710 9, 710 10, 710 33, 710 62

Abstract:

A target discovery manager associated with a target discovery layer is interposed between a host initiator and one or more discovery protocols. The target discovery manager maintains a list of target devices found by each of several target discovery protocols. For each discovered target device listed, the associated discovery protocols that discovered the target device are prioritized and coalesced into a single enumerated target device register. The target device register provides the host initiator with a single list of known target devices produced from multiple discovery protocols with the discovery protocols that independently discovered each device prioritized according to various parameters.

International Classification:

G06F 3/00
G06F 5/00

US Classification:

710 5, 710 36, 710 58, 710 60

Abstract:

A method for handling input/output (I/O) commands in a storage system includes establishing first and second counters for counting unfinished I/O commands, and establishing a reference which is initially set to the first counter. The reference is periodically switched between the first counter and the second counter, and the switching interval is less than the I/O timeout value. Upon placing an I/O command into an I/O command queue, a copy of the current reference is made into an I/O specific control block and the current referenced counter is incremented. Upon finishing of an I/O command, the counter referenced by the I/O specific control block is decremented and the I/O command is removed from the I/O command queue. When switching the reference, a problem is detected in the event that the counter being switched to is above a predetermined threshold. Upon detection of a problem, a more explicit I/O check is conducted.

US Classification:

710 2, 710 8, 710 36, 710 62, 711100

Abstract:

A storage array includes at least one target and a logical unit having a logical unit number. The storage array is configured to receive input defining a host group comprising at least one initiator and receive input defining a target group comprising the at least one target. The host group, target group and logical unit number define a view entry. The storage array is further configured to apply the view entry to the logical unit to provide a logical unit inventory that is provisioned for the at least one initiator.

Sumit Gupta - San Jose CA, US

International Classification:

G06F 16/23

Abstract:

In some examples, a system provides a data structure containing an entry to store information for an object for sharing by a plurality of entities. The system allocates the object to a first entity of the plurality of entities based on an atomic access of the entry, the atomic access to update, in one operation, multiple information elements in the entry relating to allocation of the object. The system returns, to the first entity, a handle to the object, the handle based on a value in the entry.

Abstract:

In one aspect, a graphics processing unit (GPU) data sniffing method includes the step of providing a video game software comprising a set of graphics data of a video game. The method includes the step of communicating the set of graphics data to a graphics library using an application programming interface (API) call to the graphics library. The graphics library includes at least one application API interface. The method includes the step of providing a sniffing module. The sniffing module intercepts the set of graphics data before the set of graphics data reaches the GPU. The sniffing module copies the set of graphics data to create a copy of the graphics data. The sniffing module forwards the copy of the graphics data to the graphics library for rendering to a receiving entity.
