摘要： Disclosed is a distributed file system using the token method to allow file sharing by multiple clients (nodes) for improved system throughput. A storage device for holding files, and a server for managing tokens, and multiple clients for reading and writing the files in the storage device are connected over a network. On the distributed file system by which the client requests files by tokens, the server contains a token request means for requesting the return of tokens from the client holding the file. This token return request means sends a token return request means containing information on the client requesting the files by tokens and information showing the contents of the token.

摘要： There has never been disclosed a method of executing migration on a fine-grained basis than a file system basis in a manner that is transparent to clients in a storage system with a plurality of servers to which a global name space is applied. In a storage system with a plurality of servers and a disk subsystem, which is coupled to the plurality of servers, a file system in the disk subsystem is assigned a first identifier, which is unique throughout the storage system, at least one of directories contained in the file system is assigned a second identifier, which is unique throughout the storage system, and a file contained in the file system is assigned a third identifier, which is unique throughout the file system. The server identifies a file below the directory that has the second identifier by the second identifier and by the third identifier.

摘要： A roll bar is provided behind seats of an open car, and there is provided a wind deflector to deflect air flow coming from the vehicle rear during the open-state driving on the roll bar. The wind deflector is configured so as to have air permeability in such a manner that an air permeability rate of its upper section is greater than that of its lower section. Part of air flow passes through the wind deflector. Since the amount of the air flow passing through the lower section of the deflector directed to the neck portion is suppressed compared to the air flow passing through the upper section, both the reducing of the air flow beyond the wind deflector and the suppressing of the passenger feeling displeasure with the air flow (against the neck portion) can be attained, and thereby the passenger can be prevented effectively from feeling displeasure.
摘要翻译：在打开的汽车的座椅后面设置一个滚动条，并且在打开状态下在滚动条上行驶时设置有一个导风板，用于使来自车辆后方的气流偏转。挡风板构造成具有透气性，使得其上部的透气率大于其下部的透气率。气流的一部分通过导风板。由于与通过上部部分的空气流相比，通过导向器颈部的导流板的下部的空气流量被抑制，所以减少超过挡风板的气流和抑制乘客可以实现气流（相对于颈部）的不满，从而可以有效地防止乘客感到不适。

摘要： In multiprocessing system executing processing called NUMA prefetch, when a prefetch instruction is issued to a prefetch unit, an address converter converts an address specified by an operand of the instruction into a physical address. A prefetch type determiner determines whether the instruction is an NUMA prefetch instruction or a conventional perfect prefetch instruction. If the instruction is an NUMA prefetch instruction, an address determiner determines whether the physical address is a local address or a remote address. If the address is a local address, the processing of the prefetch instruction is terminated. If the address is a remote address, a cache tag checker checks a cache. When cache hit occurs, the processing is terminated. When cache mishit occurs, a prefetch request is issued to a main storage controller. As a result, data is prefetched from a remote main storage to a cache in a local main storage.
摘要翻译：在称为NUMA预取的多处理系统执行处理中，当向预取单元发出预取指令时，地址转换器将由指令的操作数指定的地址转换为物理地址。预取类型确定器确定指令是NUMA预取指令还是传统的完美预取指令。如果指令是NUMA预取指令，则地址确定器确定物理地址是本地地址还是远程地址。如果地址是本地地址，则预取指令的处理结束。如果地址是远程地址，则缓存标签检查程序将检查缓存。当发生缓存命中时，处理结束。当发生缓存混乱时，向主存储控制器发出预取请求。因此，数据从远程主存储器预取到本地主存储器中的高速缓存。

摘要： Difference information between two snapshots from a first point-in-time snapshot, which has been copied, to an N.sup.th point-in-time snapshot, which constitutes the latest point-in-time snapshot, is acquired to a memory module. The memory module stores two or more pieces of difference information. The two or more pieces of difference information comprise difference information that shows the difference between a first point-in-time snapshot and any snapshot other than the first point-in-time snapshot of N snapshots. Copy difference information, which is information that shows the difference between the first point-in-time snapshot and a specified snapshot from among N snapshots, and which is used in copying the specified snapshot, is created on the basis of the two or more pieces of difference information.
