A method for migrating virtual machines between hypervisors is disclosed. Initially, metadata describing a virtual machine are automatically scanned and parsed. The structure of the metadata of a source virtual machine are automatically analyzed. Elements of this structure are mapped to corresponding entries of a target virtual machine. A target metadata descriptor to be used as part of the target virtual machine is generated. A predefined layout description of the data stored in a file system image of the source virtual machine read. A predefined layout description of the data to be stored in a file system image to be used at the target virtual machine is also read. The data are extracted from the source virtual machine. A template of a file system image for the target virtual system is generated. Storage space corresponding to the target virtual machine is allocated, and the extracted data are inserted into the allocated storage space.

In managing and buffering packet data for transmission out of a host, descriptor ring data is pushed in from a host memory into a descriptor ring cache and cached therein. The descriptor ring data is processed to read a data packet descriptor, and a direct memory access is initiated to the host to read the data packet corresponding to the read data packet descriptor to a data transmission buffer. The data packet is written by the direct memory access into the data transmission buffer and cached therein. A return pointer is written to the host memory by the direct memory access indicating that the data packet descriptor has been read and the corresponding data packet has been transmitted. In managing and buffering packet data for transmission to a host, descriptor ring data is pushed in from a host memory into a descriptor ring cache and cached therein. Data packets for transmission to the host memory are received and cached in a data reception buffer. Data is read from the data reception buffer according to a data packet descriptor retrieved from the descriptor ring cache, and the data packet is written to a data reception queue within the host memory by a direct memory access. A return pointer is written to the host memory by the direct memory access indicating that the data packet has been written.

A method of receiving a broadcasting signal in an apparatus for receiving the broadcasting signal, is disclosed. The method includes receiving a first encoding data descriptor describing first encoding data of contents having the first encoding data and second encoding data, in non-real time, receiving the first encoding data in non-real time, according to the first encoding data descriptor, and decoding the first encoding data received in non-real time and the second encoding data received in real time together, according to the first encoding data descriptor, and outputting the contents.

Multimedia information retrieval is performed using meta-descriptors in addition to descriptors. A “descriptor” is a representation of a feature, a “feature” being a distinctive characteristic of multimedia information, while a “meta-descriptor” is information about the descriptor. Meta-descriptors are generated for multimedia information in a repository (10, 12, 14, 16, 18, 20, 22, 24) by extracting the descriptors from the multimedia information (111), clustering the multimedia information based on the descriptors (112), assigning meta-descriptors to each cluster (113), and attaching the meta-descriptors to the multimedia information in the repository (114). The multimedia repository is queried by formulating a query using query-by-example (131), acquiring the descriptor/s and meta-descriptor/s for a repository multimedia item (132), generating a query descriptor/s if none of the same type has been previously generated (133, 134), comparing the descriptors of the repository multimedia item and the query multimedia item (135), and ranking and displaying the results (136, 137).

A text-generation method and system includes receiving data records, such that each data record includes one or more data fields and a field value associated with each data field. A text-string is generated for each data record, such that each text-string includes one or more text-based data descriptors. Each data descriptor includes a field descriptor that defines a specific data field within the data record to which the text-string is related, and a value descriptor that defines the field value associated with the specific data field.

Provided is a five sensory data synchronizing and transmitting apparatus and method, and an actual-feeling multimedia data providing system and method using the same. The five sensory data synchronizing and transmitting apparatus and method forms packets by describing vibration, an odor and a taste expressed in video/audio based on touch, odor and taste data descriptors and synchronizes the touch/odor/taste packets with video/audio packets on a frame basis; and then, the actual-feeling multimedia data providing system and method demultiplexes the received packets transmitted from the five sensory data synchronizing and transmitting apparatus into video data, audio data, touch data, odor data and taste data and transmits them to corresponding devices to thereby provide a user with an actual-feeling multimedia service.

Signaling completion of a message transfer from an origin node to a target node includes: sending, by an origin DMA engine, an RTS message, the RTS message specifying an application message for transfer to the target node from the origin node; receiving, by the origin DMA engine, a remote get message containing a data descriptor for the message and a completion notification descriptor, the completion notification descriptor specifying a local direct put transfer operation for transferring data locally on the origin node; inserting, by the origin DMA engine in an injection FIFO buffer, the data descriptor followed by the completion notification descriptor; transferring, by the origin DMA engine to the target node, the message in dependence upon the data descriptor; and notifying, by the origin DMA engine, the application that transfer of the message is complete in dependence upon the completion notification descriptor.

DMA transfer completion notification includes: inserting, by an origin DMA engine on an origin node in an injection first-in-first-out (‘FIFO’) buffer, a data descriptor for an application message to be transferred to a target node on behalf of an application on the origin node; inserting, by the origin DMA engine, a completion notification descriptor in the injection FIFO buffer after the data descriptor for the message, the completion notification descriptor specifying a packet header for a completion notification packet; transferring, by the origin DMA engine to the target node, the message in dependence upon the data descriptor; sending, by the origin DMA engine, the completion notification packet to a local reception FIFO buffer using a local memory FIFO transfer operation; and notifying, by the origin DMA engine, the application that transfer of the message is complete in response to receiving the completion notification packet in the local reception FIFO buffer.

The invention relates to a method for generating on at least one display device a graphics display of data descriptors. The data descriptors, describing items of data, are arranged on an interactive timeline as interactive timeline elements along with interactive data elements. The interactive timeline elements and the interactive data elements allow retrieval of the items of data.

Methods and systems for estimating impact between metadata descriptors are provided. A software program compares a first metadata descriptor with a second metadata descriptor and determines an impact rating between the metadata descriptors. The impact rating may be used to map metadata descriptors or as an indication of how a change in one database will effect other interrelated databases.

Methods, apparatus, and products are disclosed for repeating DMA data transfer operations for nodes in a parallel computer that include: receiving, by a DMA engine on an origin node, a RGET data descriptor that specifies a DMA transfer operation data descriptor and a second RGET data descriptor, the second RGET data descriptor also specifying the DMA transfer operation data descriptor; creating, in dependence upon the RGET data descriptor, an RGET packet that contains the DMA transfer operation data descriptor and the second RGET data descriptor; processing the DMA transfer operation data descriptor included in the RGET packet, including performing a DMA data transfer operation between the origin node and a target node in dependence upon the DMA transfer operation data descriptor; and processing the second RGET data descriptor included in the RGET packet, thereby performing again the DMA transfer operation in dependence upon the DMA transfer operation data descriptor.
