摘要:
The present invention concerns allocating files in storage apparatuses efficiently while satisfying requirements of the files. An information system 1 includes a first server system 3a coupled to a first storage apparatus 10a, a second server system 3b coupled to a second storage apparatus 10b, and a third server system 3c coupled to a third storage apparatus 10c. When the first server system 3a receives a data I/O not needing access to the entity of a file responds to the data I/O request using metadata of the file and when the first server system 3a receives a data I/O needing access to the entity of a file acquires the entity of the file from the second storage apparatus 10b or the third storage apparatus 10c to process the data I/O request. The first server apparatus determines the allocation target of the entity of the files on the basis of a requirement set for the files and information relating to configurations of the storage apparatuses 10.

According to the prior art load distribution method, there was a drawback in that the time required from discovery of increase of load to the completion of countermeasures was long. In particular, upon receiving migration of data from other file devices, it was necessary to equalize not only the load accompanying normal processes but also the load accompanying the data migration processes. In a file system receiving migration of data from a plurality of file devices, a plurality of virtual NAS (VNAS) is provided within the file storage subsystem, and an associated VNAS for executing data migration from file devices and accesses from clients is respectively associated with each file storage subsystem. Then, the state of each VNAS is defined based on the state of progress of data migration in the file storage subsystem. According to the defined state, load distribution among VNAS is performed.

A reconfigurable, multi-core processor includes a plurality of memory blocks and programmable elements, including units for processing, memory interface, and on-chip cognitive data routing, all interconnected by a self-routing cognitive on-chip network. In embodiments, the processing units perform intrinsic operations in any order, and the self-routing network forms interconnections that allow the sequence of operations to be varied and both synchronous and asynchronous data to be transmitted as needed. A method for programming the processor includes partitioning an application into modules, determining whether the modules execute in series, program-driven parallel, or data-driven parallel, determining the data flow required between the modules, assigning hardware resources as needed, and automatically generating machine code for each module. In embodiments, a Time Field is added to the instruction format for all programming units that specifies the number of clock cycles for which only one instruction fetch and decode will be performed.

The present invention relates to a method for the preparation of (3S,4S)-3-hexyl-4-((R)-2-hydroxytridecyl)-oxetan-2-one and a product of the method. The method includes the following steps: a) reducing a substance represented by formula (II) to obtain a substance represented by formula (III), and then oxidizing the substance represented by formula (III) to form a substance represented by formula (IV); b) acylating n-octanoic acid to obtain n-octanoyl chloride using thionyl dichloride, then condensing the obtained n-octanoyl chloride with 2-mercapto-pyridine under basic condition to form a substance represented by formula (V), and then converting the substance represented by formula (V) to a substance represented by formula (VI); c) reacting the substance obtained in the step a) with the substance obtained in the step b) under catalytic condition of Lewis acid to generate a substance represented by formula (VII), and then reacting with a Lewis acid. The meanings of the signs in these formulas are the same as those in the description.

The present disclosure provides a new type of gapless semiconductor material having electronic properties that can be characterized by an electronic band structure which comprises valence and conduction band portions VB1 and CB1, respectively, for a first electron spin polarisation, and valence and conducting band portions VB2 and CB2, respectively, for a second electron spin polarisation. The valence band portion VB1 has a first energy level and one of CB1 and CB2 have a second energy level that are positioned so that gapless electronic transitions are possible between VB1 and the one of CB1 and CB2, and wherein the gapless semiconductor material is arranged so that an energy bandgap is defined between VB2 and the other one of CB1 and CB2.
摘要:
A configurable adaptive variable length data packet transmission output scheduler for enabling substantially simultaneous transmission on a common transmission link, as of fiber optics, of differentiated services for various different traffic types, executing different QOS algorithms while co-existing in a converged network environment, with simultaneous preserving of the different service characteristics for real-time or high-priority traffic and providing differentiated bandwidth allocation while achieving maximal link utilization—all through a fine and balanced control as to which type of traffic is transmitted on the link for a given duration, and how much of that traffic is transmitted on the link.

There is provided an apparatus 2 for desalinating non-potable water. The apparatus has a first vapor producing module 5 configured to receive a heated working fluid for producing vapor from a volume of non-potable water for driving at least one first distillation module 10 for producing condensate 12. The apparatus also includes a second vapor producing module 14 configured to receive working fluid from the first vapor producing module 5 for producing additional vapor from a further volume of non-potable water 8′.
摘要:
A dynamically reconfigurable network architecture includes a plurality of switching modules arranged in an ordered, multi-level, switched-tree configuration. A network is formed by selecting one switching module as the root and assigning it and all directly or indirectly subsidiary modules to the network. The operating mode of each switching module can be dynamically selected as either circuit-switched or packet-switched. The modules can be grouped into a single network or into a plurality of separate networks operating in parallel, including both circuit-switched and packet-switched networks. When a network is no longer needed, its operation can be halted and its resources released for reassignment to other networks. In embodiments, a selector controlled by allocation registers selects either a circuit-switching sequencer or a packet connection arbitration circuit to control the switching circuits. Switching modules can include crossbar switches. Circuit-switched connections can use TDM to share allocated physical resources.
