A technology capable of achieving the LU migration in terms of a file system and a logical volume and the effective migration in a host computer which provides a file system function and a logical volume function is provided. A computer system has I/O access unification and management means that obtains RAID configuration information and RAID statistical information in a disk array system and manages an I/O access unified management table in which file system configuration information and logical volume configuration information managed by an OS are unified. Also, the computer system has migration volume deciding means that determines a migration method based on the I/O access unified management table, migration influence predicting means that obtains migration influence prediction information, and RAID linkage migration performing means.

Each node includes a node controller for decoding the control information and the address information for the access request issued by a processor or an I/O device, generating, based on the result of decoding, the cache coherence control information indicating whether the cache coherence control is required or not, the node information and the unit information for the transfer destination, and adding these information to the access request. An intra-node connection circuit for connecting the units in the node controller holds the cache coherence control information, the node information and the unit information added to the access request. When the cache coherence control information indicates that the cache coherence control is not required and the node information indicates the local node, then the intra-node connection circuit transfers the access request not to the inter-node connection circuit inter-connecting the node but directly to the unit designated by the unit information.

A parallel computer using a simply structured network which allows loads on message-transferring routes to be as equally distributed as possible and which eases possible conflict between different types of messages being transferred. Given a message to be transmitted, each processor (PE) on the network references a property setup table to determine property information depending on the message type and places the information into the message. For example, a route bit RB as the property information is set to "0" or "1" depending on whether the message is originated by the sending PE or is a message acknowledging the receipt of another message. According to the RB bit in the received message, a route instruction circuit in each exchange switch (EX) references a route instruction table to determine the message destination that depends on the receiving PE number designated by the message. Each EX has a plurality of virtual channel circuits. Each virtual channel circuit has a plurality of buffers assigned beforehand to different values of the RB bit within the message. The received message is placed into the buffer corresponding to the RB bit value of the message, whereby conflict between messages is minimized.

In a step for bonding a color filter to a solid-state image sensor so as to provide a color-sensitive image sensor (to be referred to as "a color-image sensor" in this specification), a method for bonding the color filter to the image sensor with an adhesive which is curable by ultraviolet radiation and also the constructions of color filters and image sensors which can facilitate the bonding step. Further techniques for mass producing high-precision and high-quality solid-state color-image sensors, each of which is bonded with a color filter with a higher degree of accuracy in alignment and by a higher degree of adhesive strength, by carrying out the bonding step in an atmosphere containing oxygen so as to inhibit an adhesive squeezed out of the space between the image sensor and the color filter from being cured and subsequently facilitate the removal of uncured adhesive and by forming protective layers or films over the surfaces to be bonded of the image sensor and color filter prior to the bonding step so as to prevent these surfaces from being damaged during the bonding step.

In a multi-tenant information processing system, when initially constructing a tenant, design items depending on the tenant are specified for each device constituting the tenant, and design values of the design items are calculated without overlapping with those of other tenants. In a tenant design item management table, the design items set for the devices and information indicating whether the design items depend on the tenant, are stored for each device. In a design algorithm management table, calculation formulae for making the design values to be different for each tenant are stored corresponding to the design items. A tenant design unit refers to the tenant design item management table, specifies the design items depending on the tenant among those corresponding to the devices constituting the tenant, calculates the design values of the design items according to the calculation formula, when initially constructing the tenant.

A computer system reduces an overhead by using an I/O switch high in versatility when realizing the sharing of an I/O between virtual computers. The system includes a CPU module #0 having plural CPU cores, an AS bridge 15 connected to the CPU cores, and a main memory that can be accessed from the CPU cores or the AS bridge 15, and AS switches SW0 and SW1 that connect the AS bridge 15 of the CPU module #0 and an I/O blade #5. The CPU module #0 has a hypervisor that divides the plural CPU cores and the main memory into plural logical partitions, and the AS bridge 15 adds virtual path information set in each of the logical partitions and path information of from the AS bridge 15 to the I/O blade #5 to the path information of the AS packet to switch over the AS packet between each of the logical partitions and the I/O blade #5 when relaying the AS packet transmitted or received between the logical partitions and the I/O blade #5.

To improve throughput in data transfer in a remote I/O system, this invention provides a computer system including: a host computer; a device which communicates with the host computer; and a network which connects the host computer and the device, in which the device is coupled to the network via a device bridge including a bridge memory, and the host computer includes a host memory and a device driver. The device driver writes, when at least one of data and an address is written in the host memory, in the bridge memory the at least one of the data and address stored through the writing in the host memory; and sends a data transfer request to the device bridge, and the device bridge reads, upon reception of the data transfer request, an address from a predetermined area; and reads data from an area that is indicated by the read address.
