摘要： An object movement control system, an object movement control method, a server, and a computer program that can update the positional information of an object in a virtual space at high speed by appropriately distributing processing loads. Client control units obtain information about the position of a first object in a virtual space and information about movement of the first object and detect other objects that exist in a virtual region that contains the first object, which has been moved. The distances between objects that exist in a virtual region are calculated, and only when the number of objects the distances to which are shorter than a predetermined threshold exceeds a predetermined number, information about the objects is sent to a server. The server assigns a collision determination client that performs collision determination to each pair of objects selected from the objects.

摘要： A system acquires an output program for sequentially executing a plurality of character string output instructions, and thereby for outputting a text in which a plurality of output character strings are combined. The system converts the character code set of the character string constants, which is outputted by at least one of the character string output instructions, from a first code set for internal processing to a second code set for output, before the output program is executed. In addition, the system buffers the values of two or more character string variables to be outputted by two or more of the character string output instructions without converting the character code set from the first code set, during the execution of the output program.

摘要： The present invention improves efficiency in processing for outputting a character string. A system of the present invention firstly acquires an output program for sequentially executing a plurality of character string output instructions, and thereby for outputting a text in which a plurality of output character strings are combined. The system then converts the character code set of the character string constants, which is outputted by at least one of the character string output instructions, from a first code set for internal processing to a second code set for output, before the output program is executed. In addition, the system buffers the values of two or more character string variables to be outputted by two or more of the character string output instructions without converting the character code set from the first code set, during the execution of the output program. Moreover, the system collectively converts the character code set of the values of the two or more buffered character string variables, from the first code set to the second code set. Furthermore, the system outputs the character string constant whose character code set has been converted; and the values of the two or more character string variables whose character code set has been converted, as at least a part of the text.

摘要： A method of converting a program code of a program running in multi-thread to a program code which causes fewer lock collisions. The method includes reading the program code into a memory and searching the program code for a first conditional statement making a branch to a path, which is in a synchronized block and has no side effect on the synchronized block; duplicating the path having no side effect to which the branch is made by the searched first conditional statement into the outside of the synchronized block; and adding a second conditional statement into the program code in response to the duplication, wherein the second conditional statement is a conditional statement making a branch to the duplicated path having no side effect. Also provided is a system and an article of manufacture which causes a computer to carry out the steps of the above method.

摘要： It is one object of the present invention to provide a program execution method for performing greater optimization. A program execution apparatus according to the present invention performs a transfer from an interpreter process to a compiled code process in the course of the execution of a method. At this time, if no problem occurs when a transfer point is moved to the top of a loop, the transfer point for code is so moved. And when a transfer point is located inside a loop, a point that post-dominates the top of the loop and the transfer point is copied to a position immediately preceding the loop. Then, information for generating recalculation code is provided for the transfer point, and a recalculation is performed.

摘要： A method, computer system, and computer readable article of manufacture for converting a first program code in a multi-threaded program into a second program code which causes less lock contention. A processing unit determines whether the first program code includes either a first class having a method call to a third class that operates while taking synchronization by locking, or a second class inheriting a parent class that operates while taking synchronization by locking. If the first class, then it is converted into a class with a method call to a concurrent operation executable class that is functionally equivalent and a shorter lock holding section. If the second class, then it is converted into a class with a method call to a concurrent operation executable class that is functionally equivalent to that of the parent class, and a shorter lock holding section.
