Abstract: A processing system includes a plurality of processors and a bus to carry messages between the processors, wherein each of the processors has an operating instruction memory field holding stored operating instructions including a re-routing target address. Each processor is arranged to receive a message including operating instructions including a current target address and on receipt of the message operate as a current processor arranged to: check whether the current target address corresponds to an address associated with the current processor; if the current target address in the message does correspond to the address associated with the current processor, check the operating instructions in the message to determine whether the message is to be re-routed; and, if the message is to be re-routed, replace operating instructions within the message with the stored operating instructions, and place the message on the bus for delivery to the re-routing target address.

Abstract: Methods and systems for a copy-offload operation are provided. A soft range lock is placed for a data container for generating a token for a copy-offload operation for copying the data container from a source location to a destination location, where presence of the soft range lock indicates that content of the data container has not changed during the copy-offload operation. A token for the copy-offload operation represents the content of data container and includes information regarding the soft range lock. The token with the soft range lock information is provided to the client that requests the copy-offload operation. If the soft range lock exists, then the data container is copied without using a point in time copy of the data container.

Abstract: Method and system for detecting migration of a virtual machine are provided. The method detects that a first identifier for identifying a virtual machine and a second identifier identifying a source computing system hosting the virtual machine that accesses a storage space via a logical object have changed, when the virtual machine is migrated from the source computing system to a destination computing system. Thereafter, a storage device at the destination computing system is initialized to operate as a caching device for the migrated virtual machine.

Abstract: Storage device performance alignment notification includes informing a storage device of a starting logical block address (LBA) for each of one or more host containers to be stored on the storage device, and placing the one or more host containers at natural storage boundaries of the storage device based at least in part on the informing.

Abstract: The present disclosure involves a method. As a part of the method, a logically sequential range of memory blocks is allocated for sequential access. A pointer is initialized with an address of a first memory block that is within the range of the memory blocks. In response to a data write next request, data is written into the range of the memory blocks, starting with the first memory block and continuing sequentially in subsequent memory blocks within the range until the data write next request is completed. Thereafter, the pointer is updated based on a last memory block in which data is written.

Abstract: A processing system comprises a plurality of processors (12) and communication means (20) arranged to carry messages between the processors, wherein each of the processors (12) has an operating instruction memory field (32, 34, 36) arranged to hold stored operating instructions including a re-routing target address. Each processor is arranged to receive a message (38) including operating instructions including a target address.

Abstract: A method of implementing an invention exchange includes soliciting an invention disclosure of an invention, publishing the invention disclosure, selling a plurality of shares of rights to the invention to raise revenue, establishing a first threshold, determining if at least one of the revenue, number of shares sold, and total size of shares sold exceeds the first threshold, and based at least in part on the determining, causing at least one of a prior art search report to be drafted on the invention and a patent application to be drafted on the invention.

Abstract: A system and method are provided that allow for improved code sequence verification through the use of an abstract syntax tree. This is accomplished by first constructing an abstract syntax tree from the code sequence and then determining whether the abstract syntax tree satisfies a predefined set of conditions indicative of the code sequence being executable on the computer without generating a predefined class of execution errors. The abstract syntax tree is constructed by reassembling the code sequence into a plurality of instructions, combining the instructions into a plurality of blocks, examining the blocks to determine entry points of a plurality of loops, and tagging locations in the series of instructions where control is transferred at the end of each loop. The instructions, blocks, loops and tagged locations are then examined to generate a plurality of control structures (the coarse structure).
