摘要:
A job scheduling analysis method and system are disclosed in which a job schedule is analyzed by use of historical job execution data in a computer system in which a plurality of jobs are executed in parallel. Historical execution data of a plurality of jobs and the file names of files accessed by the jobs are collected. The maximum multiplicity of jobs capable of operating in parallel on the computer system is inputted. When the file name of a file accessed by one job and the file name of a file accessed by another other job coincide with each other, an execution start condition of the plurality of jobs are determined to execute the one job and the other job at the earliest instants within the maximum job multiplicity so that the sequence of execution of processings by the one job and the other job is maintained and the execution time of the one job and the execution time of said other job do not overlap each other. Thereby, it is possible to simulate the influence of a change in system construction and to search for an effective batch processing with a reduced number of idle spaces.

摘要:
In a fault recovery method for a multi-processor system including a main storage and a plurality of virtual machines which are assigned to a plurality of processors under control of a host operating system and a plurality of guest operating systems and which operate on the processors associated therewith, a fault occurring in one of the processors is detected to recover functions of the system. The method includes the steps of setting recovery attributes for failure to each of the virtual machines, assigning a plurality of virtual machines to a plurality of processors and operating the virtual machines on the processors respectively associated therewith, storing, at detection of occurrence of a fault in one of the processors, data and status information of virtual machines assigned to the processor and status information of the processor respectively in a virtual machine save area and a real machine save area of the main storage, storing fault information of the processor in the main storage by a fault recovery circuit having received a report of the fault, restarting an interrupted process and causing an interruption according to the status information of the virtual machines and the status information and fault information of the processor which are obtained from the main storage, and retrieving, when the interruption is received, one of the virtual machines assigned to the processor according to the processor status information in the real machine save area and then assigning the plural virtual machines to the plural processors for operation thereof according to the recovery attributes for failure set to the retrieved virtual machine.

A friction stir welding device (1) includes a workpiece disposition unit (2) at which workpieces (W) is disposed, a main body section (3) disposed at a surface (W4) of the workpieces (W) disposed at the workpiece disposition unit (2), a tool holding unit (4) formed in the main body section (3) to enable advance and retreat in a direction facing the workpieces (Z), which is a direction approaching and separating from the workpieces (W) disposed at the workpiece disposition unit (2), and configured to hold a tool (100), and a support medium (5) formed to satisfy a predetermined relative positional relationship in the direction facing the workpieces (Z) with respect to a first shoulder surface of the tool (100) attached to the tool holding unit (4) and configured to support the tool holding unit (4) on the surface (W4) of the workpieces (W) disposed at the workpieces disposition unit (2).
摘要:
In a memory hierarchy system having two or more hierarchy storages of different access speeds and programs and/or data to be loaded on the hierarchy storages, an activity information acquisition unit and a display unit are provided to present information regarding selection of programs and/or data to be loaded on a higher level in memory hierarchy, a unit is provided which automatically decides loading of the programs and/or data on the higher level and executes reallocation of the programs and/or data on the basis of the information, and a unit is provided which permits the user to change the loading by using a user command. The user can make full use of these units during execution of the memory hierarchy control. In an embodiment, priority for the programs and/or data to be loaded on the higher level is calculated and decided. The programs and/or data are written into the real storage in accordance with their priority to increase the real storage hit rate upon occurrence of a next request for loading.

The present invention aims to provide a fluorine-containing polymer powder that is environmentally less harmful and forms a sufficiently smooth film without impairing the properties of the fluorine-containing polymers. The present invention relates to a fluorine-containing polymer powder including a fluorine-containing polymer prepared by suspension polymerization, which contains less than 0.1 ppm of a fluorine-containing surfactant and has an average particle size of not less than 1 μm and less than 100 μm and a bulk density of 0.90 to 1.50 g/cm3.
摘要:
In an organic EL panel inspection method, to determine whether an organic EL panel is good or bad, a plurality of voltages having different values are sequentially applied to the organic EL panel, thereby measuring the respective currents. According to the currents, the following three criteria are checked: criterion (1), whether or not a spike current is present in the measured currents, criterion (2), between when the plurality of voltages are sequentially applied from one direction to the other direction of the voltage and when the plurality of voltages are sequentially applied from the other direction to the one direction, whether or not currents having different current densities occur at the same voltage, and criterion (3), the absolute value of the current density of current flowing when a predetermined voltage in the reverse direction is applied to the organic EL panel.

It is an object of the present invention to provide a one-pack type fluororubber coating composition which is a material based on a polyol-curable coating excellent in sealing performance and can directly form a rubber coat layer on the metal surface without using any primer and, further, can satisfy the performance characteristics required in auto engine evaluation, such as the antifreeze resistance, oil resistance and heat resistance. The fluororubber coating composition of the present invention comprises a fluororubber, a polyol curing agent and a mercapto-group-containing metal compound each dissolved or dispersed in a liquid carrier.
摘要:
A coating composition of a fluororubber containing a fluorine-containing elastomeric copolymer which has repeating units of the formula: —CH2— in the backbone, a polyol curing agent, and a salt or a complex compound of a basic compound having a pKa of at least 8 and an organic acid as a curing accelerator. This composition is a one-pack type composition having a long pot life, and can provide a cured coating in a short time at a relatively low temperature. Furthermore, this composition can be applied by dispenser type coating or screen printing, even when the concentration of the fluorine-containing copolymer is high.
