The present invention addresses the problem of providing a migration system and a migration method by which a completion timing of a live migration of virtual machines can be adjusted. The migration system () comprises: a transfer means (A) for transmitting memory data of the virtual machines from a transfer source physical host () to a transfer destination physical host () to synchronize data of the virtual machines on the physical host () and the virtual machines on the physical host (); a determination means (A) for determining, for each of the virtual machines, whether the data of the virtual machine (A) on the transfer source physical host () is synchronized with the data of the virtual machine (B); and a control means () for issuing an instruction of switching from the virtual machines on the physical host () to the virtual machines on the physical host (), if the data of all the virtual machines is synchronized based on the determination result. The transfer means (A) continues transmitting the memory data until the instruction of switching is issued.

A domain management apparatus instructs physical nodes about the configuration of virtual nodes and virtual links of virtual networks. The physical nodes assign a virtual machine to a virtual node based on the definition of the virtual node contained in an instruction from the domain management apparatus. The physical nodes write a configuration associating virtual interfaces in the virtual node definition with virtual NICs on the virtual machine into a configuration file of the operating system to be started up on the virtual machine before the start-up of the virtual machine and, then, start up the virtual machine. Therefore, it is possible to recognize the correspondence relation between the virtual interface in the virtual node definition and the virtual NIC in the virtual machine without referring to the virtual network assignment result and without waiting for the start-up of the virtual machine.

Prefixes are registered on a first list as index elements for respective registration patterns. Each prefix is selected as the longest of different-length prefixes that are extractable from a registration pattern in accordance with an extraction rule. Suffixes, which are the remaining parts of the registration patterns excluding the respective prefixes, are registered on a second list. Using different-length prefixes that are extracted from a retrieval key in accordance with the extraction rule, a prefix retriever searches the first list to retrieve a registration pattern whose prefix matches any of the prefixes of the retrieval key. A suffix checker carries out a check on the suffix of the registration pattern retrieved by the prefix retriever, among the suffixes on the second list, as to whether the suffix of the registration pattern matches the suffix of the retrieval key.

Efficient retrieval of variable-length character string data

A data processing device includes a memory, a processing unit, a logic element, a first database and a management unit. The memory stores a plurality of software modules which processes input data. The processing unit enables to execute the plurality of software module. The logic element enables to configure a plurality of hardware modules, which can perform processings equivalent to those performed by the plurality of software module, using a dynamic reconfiguration. The first database stores configuration information indicating a configuration of the plurality of hardware modules when the plurality of hardware modules is set to the logic element. The management unit determines a first software module to be set to the logic element as a hardware module in the plurality of software modules on the basis of a predetermined condition with respect to a processing of the input data, and sets a first hardware module corresponding to the first software module to the logic element with reference to the first database.

Data processing device and data processing method

A data retrieval system includes a retrieval request block for generating a retrieval key including a current state number and a current character string including N characters latched from an input character string, and a state transition memory operating for retrieval based on a state transition table. The state transition table includes a plurality of input entries each including a combination of a current state number and a character pattern string having N characters, and a plurality of output entries each including combination of a next state number and a pattern number of a character pattern retrieved from the input character string. The state transition memory operates for a plurality of retrievals in parallel retrieval processing.

Method and system for retrieving a data pattern

The assignment result reception circuitreceives the accumulation assignment result from the external portion, and sends the already-assigned input port and output port information to the assignment request mask circuit. The assignment request mask circuituses the already-assigned input port and output port information received from the assignment result reception circuit, performs the mask process on the connection assignment request received from the external portion, and sends its result to the M&#xd7;N scheduler circuit. The M&#xd7;N scheduler circuitdetermines the assignment of the port connection in accordance with the information received from the assignment request mask circuit, and sends the connection assignment result to the external portion and the assignment result transmission circuit. The assignment result transmission circuitcarries out the logical OR between the connection assignment result received from the M&#xd7;N scheduler circuitand the accumulation assignment result received from the external portion, and outputs to the external portion. Thus, it is possible to carry out the connection assignment effectively with small waste.

A method and apparatus for recording electrocardiogram information, in which ST deviation can readily be visualized and ischemia can be diagnosed with ease at the same time. Compressed recorded waveforms of electrocardiogram waveforms are partitioned and recorded as compressed waveforms of a plurality of lines in a first recording area of a recording paper for recording electrocardiogram information. A predetermined number of lines of the recorded compressed electrocardiogram waveforms in the first recording area are selected in a second recording area neighboring the first recording area, the selected waveforms are superimposed in synchronism with a predetermined characteristic point of the selected waveforms, and the waveforms are recorded while changing location in the area neighboring the predetermined lines of the first recording area. An HR graph and an ST-trend graph of the electrocardiogram waveforms recorded in the first recording area are recorded in recording lines approximately perpendicular to the recording lines of the compressed electrocardiogram waveforms from a position of a recording starting line of the compressed electrocardiogram waveforms of the first recording area.
