摘要： When a subject of access of a transaction from an IO device is not any resource allocated to a logical partition to which the device having issued the transaction belongs, a report as an error is sent to a CPU, while the transaction is finished on the IO bus. To prevent a transaction between IO devices from gaining access to any resource in another logical partition, one access permission bit is provided for each combination of all the IO devices, and the access is permitted only when the bit has a predetermined value. A reset signal is provided by IO slot so that only an IO slot allocated to a specific logical partition can be reset without affecting any other logical partition. A transaction issued from an IO device in one logical partition is prevented from gaining access to a resource in another logical partition, while proper error handling can be performed.

摘要： A sever includes an SVP 206 which is a control device capable of executing processing independent of a CPU, and an interrupt 314 is periodically applied to the CPU. An SVP device driver 303, being triggered by the interrupt 314, acquires an amount of server resources used, such as CPU operating time and memory capacity, and user information used by using an API provided by an OS, and delivers such information to an SVP 206. The SVP 206 transmits resource information thus delivered to an accounting server via an NIC 211. The accounting server accounts an amount of server resource used on a user basis and bills the users according to the quantity of server resource used. With such arrangement, it is possible to accurately grasp the usage status of server resource regardless of server loading, and further, it is possible to execute accounting of server resources and billing based on such accounting regardless of types of OS or CPU.

SVP 206经由NIC211发送这样传送给计费服务器的资源信息。计费服务器根据用户的用户数量来计算使用的服务器资源量，并根据所使用的服务器资源的数量向用户收费。 通过这样的配置，无论服务器负载如何，都能够准确地掌握服务器资源的使用状态，而且，无论OS或CPU的种类如何，都可以基于这样的计费来执行对服务器资源的计费和计费。

摘要： A cache controller stores pre-set variables for pre-fetch block size and stride value. A cache controller receives an access request for the main memory from the processor, and generates a pre-fetch request based an the access request and the variables. The cache controller reads data from main memory based on the generated pre-fetch request and writes this data to the cache memory.

摘要： An information processing system that transfers transactions between a plurality of system modules. A request side interface unit in a request side module has a request ID queue in which issued request transactions are stored in order of issuance. A request side queue pointer points to an entry in this request ID queue corresponding to a response transaction to be accepted next. A response side interface unit in a response side module has a response queue in which accepted request transactions are stored in order of acceptance. A response side queue pointer points to an entry in this response queue corresponding to a response transaction to be issued next. Therefore, a request transaction and the corresponding response transaction are transferred between the request side interface unit and the response side interface unit without transferring transaction IDs. When the response order is changed, the response side interface unit issues a command, which changes the value of the request side queue pointer, to inform the request side interface unit of the change in the order.

摘要： A spark ignition internal combustion engine includes a sub-combustion chamber in which gas mixture with an air-fuel ratio adapted for an operating state of the engine over a wide operating range of the engine is supplied to a combustion chamber. The amount of hydrogen carbide discharged is less and a high efficiency can be attained. The sub-combustion chamber of the internal combustion engine communicates with the main combustion chamber. Gas mixture injecting apparatus intermittently injects gas mixture into the sub-combustion chamber. Ignition devices are arranged in the sub-combustion chamber. The engine is constructed such that the sub-combustion chamber is eccentric in a sideward direction from an extending line of injecting direction of the gas mixture injecting apparatus and communicated with the main combustion chamber. The gas mixture injecting apparatus includes a pressure accumulating chamber adjacent to the sub-combustion chamber and to which pressure air is filled, the opening or closing valve to cause the pressure accumulating chamber to be communicated with the sub-combustion chamber in such a way that they may be opened or closed, and the fuel injecting valve for injecting fuel to the pressure accumulating chamber.

摘要： A next-generation OS with a virtualization feature is executed as a user program on a first virtual processor by selecting, in response to a cause of a call for a host VMM, one of a guest status area (221) for executing a user program on a second virtual processor and a host status area (222) for executing the guest VMM, and by updating a guest status area (131) of a shadow VMCS for controlling a physical processor. Accordingly, without a decrease in performance of a virtual computer, the next-generation OS incorporating the virtualization feature is executed on a virtual server, and the next-generation OS and an existing OS are integrated on a single physical computer.
