Abstract: A parallel computer system includes a plurality of processors, each of which is placed in data communication with an interconnecting network. Pairs of a data signal and a data identification code, predetermined for the data signal, are received by each processor and stored in a memory. Structure is provided for reading a data signal belonging to one of the pairs having a data identification code designated by a data readout instruction.

Abstract: A parallel computer has an operation request function and a plurality of processor elements. Each processor element has a sharable distributed memory for holding data, and is interconnected to a network to permit communication. Each processor element comprises a request sent unit for sending an operation request message for causing another processor element connected to a memory module to execute a recursive defining operation. The memory module stores data to be recursively defined. Each processor element further comprises an operation request execution element for accepting a message from another processor, temporarily stopping any other operation of the processor element in accordance with the content of the message, and executing the requested operation. Registers are also used for executing the operation requested by the other processor in addition to the general purpose registers and floating point registers.

Abstract: A plurality of elemental processors each include a local memory for storing data and task programs and an execution section for executing the task programs. A communications section transfers data among the processors. In a method of parallel processing with these elemental processors, a task program is executed in one of the processors. A detection operation is conducted to determine whether the data from the task program is to be copied to the local memories of other processors. The detection is based on predetermined information which is stored in the local memory of the processor which performs the task program and indicates which of the other processors will need the data. The detection also determines which of the other processors that will require access to the data are ready to receive the data.

Abstract: An enzyme immobilized membrane comprising an anisotropic ultrafiltration membrane having a porous layer and a dense layer, and an enzyme immobilized therein is disclosed. The porous layer of the ultrafiltration membrane retains a water-soluble polymer having at least two functional groups in the crosslinked state, and the enzyme is covalently bonded to the membrane through the functional groups of the polymer. Preferably, the membrane is prepared from polysulfone. The enzyme immobilized membrane is produced by a process which comprises impregnating a solution of the water-soluble polymer into the porous layer of the ultrafiltration membrane under a pressure of 0.1 to 1.0 kg/cm.sup.

Abstract: 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.

Abstract: A sequence of calling clauses and all clauses in a procedure that includes the selected clauses are displayed simultaneously, and the present point of execution is displayed being overlapped on the above displays. In particular, the program source list of a procedure being processed is displayed, and the latest execution statuses of the executed terms are graphically displayed around the terms on the displayed program source list.

Abstract: In order to improve the efficiency of test and debug procedure based on delarative program understanding of a program described by a logical language, the operation which has been executed for each procedure is grasped. On the basis of information relating to the grasped operation, the operation range of each procedure is expressed clearly by making thick only sides which have actually operated among four sides of a box-shaped figure surrounding each head term and end body term of each clause included in each procedure.

Abstract: In order to highly speed up the pattern matching of tree structured data in a logic programming language, the priority order is set when the data owned by the individual nodes of a tree structure are to be transversely sought, and the tree structured data are expressed in a vector type, in which they are arranged in that priority order, so that they are compared consecutively from the head for each element of the vector.
