摘要:
A dependent element group which is invertibly contractible is found by using program analysis information including a plurality of dependent elements representing dependent relationships of statement and control, the statement and the control being included in a program. Next, a program dependence graph in which dependent elements are made to be contracted is generated by contracting the found dependent element group. The number of vertices and the number of edges of the program dependence graph are reduced by the contraction of the dependent elements, so that a program dependence graph with a rough granularity can be generated. As a result, a calculation amount (calculation time) necessary for optimization processing such as parallel processing of the program can be reduced. That is, by generating the contracted program dependence graph having invertibility, it is possible to realize the analysis and optimization of large-scale software in a realistic time.

When a normal interrupt occurs, data of processor operation before the normal interrupt are held in a normal return address register (452), a normal previous state register (453), and a normal factor register (454). When a break-interrupt occurs, data of processor operation before the break-interrupt is held in another break return address register (455). Hence, a break-interrupt can occur even within an interrupt inhibition period by a normal interrupt. Besides, when a break-interrupt occurs, the break-interrupt state is set in a flag register (456). By referring to the flag register (456) in executing an interrupt return instruction, the operation data before the break-interrupt or before the normal interrupt can accurately be restored.
摘要:
A first processor makes a procedure call, specifying an address of a procedure in an address space controlled by a second processor and an address of procedure control information generated in an address space controlled by the first processor. The second processor executes the procedure present at the address specified by the first processor. Upon finishing of execution of the procedure, the second processor returns the address of the procedure control information to the first processor. The first processor changes the execution status included in the procedure control information at the address returned from the second processor from “being executed” to “completed”.

Data shared by plural processes of a program are identified and identification information is affixed to the shared data. When the program is linked by a linker, only the shared data to which identification information is affixed are extracted and a shared data area is created for the shared data. During program execution, this shared data area is prevented from being and the main memory is referred to or updated or the cache is invalidated prior to access of the shared data area by the linker. An address of data in a processor is computed from an address of the data in another processor based on a specific expression.
摘要:
In a computer system having a plurality of processing elements (PE#0 to PE#n) and adopting a distributed-shared-memory-type multiprocessor scheme, a master PE (for example, PE#0) executing a multi PE loader transfers an MPMD program for PE#k to a predetermined area of memory space of PE#0 to which a unique memory (LM) of PE#k is temporally allocated. The LMs of PE#1 to PE#n can be allocated to different areas of the memory space of PE#0 respectively, or can be allocated the same area thereof.

摘要:
It is an object of the invention to provide a method and an apparatus for processing a very large number of fish eggs for gene injection and so on with a superior performance. An egg case has an egg-arranging plate and a cover plate. The fish eggs are dropped into concave portions of the egg-arranging plate, when the cover plate opens the concave portions. The cover plates closes the concave portions after fish eggs are accommodated in the concave portions.The egg case is fixed on a table of an egg-arranging apparatus. water is supplied on the egg-arranging plate in the egg plate. A scanning nozzle sprays water on upper surface of the egg-arranging plate. After closing the concave portions with the cover plate, the egg case is inclined for dropping fish eggs remaining on the cover plate.
