Parallel computer with distributed shared memories and distributed task activating circuits

摘要

In accessing a memory, each element processor executes a program constructed so as to designate an address belonging to a predetermined local address area for each element processor. When a memory write instruction is executed by an element processor, it is detected if the memory address designated by the instruction coincides with a predetermined address. If detected, a predetermined address belonging to a local address space of another element processor and assigned to the first-mentioned predetermined address, and the data written in response to the write instruction, are sent to the other element processor to instruct the data to be written therein as a copy data. A next task to be executed is decided independently for each element processor.
