Abstract: PROBLEM TO BE SOLVED: To allow a CPU to directly read and execute a boot code even when the size of the boot code exceeds the storage capacity of a randomly accessible buffer.
SOLUTION: A code B0 is read from a storage part 110 of a NAND flash memory 100 to a buffer part 120 randomly accessible from a CPU 200, the buffer part being provided in the flash memory 100. The code B0 read in the buffer part 120 is executed, whereby a code B1 is retained in a cache memory 210. The cached code B1 is executed, whereby a code APP that is a boot code is read from the storage part 110 to the buffer part 120, and retained in the cache memory while changing the base address. Further, cached codes APP are successively executed by jumping from the code B1 to the code APP.

Abstract: PROBLEM TO BE SOLVED: To swiftly change the operation using a local disk of a computer to a diskless operation when a failure occurs in the local disk. SOLUTION: A system includes a cluster 11, a cluster 12 and an image server 20. A host 101a constituting the cluster 11 has a root file system 111a for operating the host 101a in the local disk. The image server 20 has a root file system 221a for operating the host 101a, and the host 101a virtually constructs a root file system 121a by mounting the root file system 221a. When the root file system 111a is changed, the host 101a synchronizes the root file system 111a with the root file system 121a. The same applies to a host 102a constituting the cluster 12.

Abstract: PURPOSE: To facilitate transfer operation and restore data efficiently at a high speed in the case of fault occurrence by providing plural storage means, a data bus, and a selecting means having a function for parity arithmetic operation. CONSTITUTION: Two channels of 4-channel crossbar switches 11a and 11b having an exclusive OR operation function are connected to data buses DDO and DD1 as common buses. Other two channels of the crossbar switch 11a as the selecting means are connected to drives HDDO and HDD1. Other two channels of the crossbar switch 11b are connected to drives HDD2 and HDD3. Further, the crossbar switches 11a and 11b are controlled with an address signal and a control signal outputted from a data bus controller 13, and connections in optional combinations of drives and data buses are enabled. Thus, the selecting means itself is provided with the function for parity arithmetic operation.

Abstract: PROBLEM TO BE SOLVED: To provide a DMA (direct memory access) transfer technology which is adapted to HILS and can suppress an overhead.
SOLUTION: In this computer system including a data transfer device for transferring data to a peripheral apparatus from a memory of a computer by DMA, a continuous DMA mechanism responds to perform processing and continuously repeatedly gives a data transfer request. In a simulation system for the HILS, data on a result of simulation are arranged in a prescribed area of the memory. In response to the data reading transfer request from the continuous DMA mechanism, the data are transferred to the continuous DMA mechanism from the memory together with data on a generation ID. The continuous DMA mechanism stores the transferred generation ID as a reception ID, and receives the transferred data in response to an effect that the transferred generation ID differs (having updated) from the stored reception ID. The continuous DMA mechanism continuously repeats the data transfer request until it is disabled.

Abstract: PROBLEM TO BE SOLVED: To provide a method, a program and a system capable of guaranteeing a deployed application operation at all times, and capable of dynamically deploying an application according to resource states in each client node. SOLUTION: When a job is input, a job scheduler 110 decides deploy information of the application according to the resource states of a client node 300. An application execution environment management agent 210 discriminates whether an application execution environment in the client node 300 matches with an application execution environment in which the operation has been verified. Then, when they match, the application execution environment management agent 210 notifies the job scheduler 110 that deployment can be made, and when they do not match, the application execution environment management agent 210 switches to a matched application execution environment by restarting the client node 300.
