A method for increasing performance of an operation on a distributed memory machine is provided. Asynchronous parallel steps in the operation are transformed into synchronous parallel steps. The synchronous parallel steps of the operation are rearranged to generate an altered operation that schedules memory accesses for increasing locality of reference. The altered operation that schedules memory accesses for increasing locality of reference is mapped onto the distributed memory machine. Then, the altered operation is executed on the distributed memory machine to simulate local memory accesses with virtual threads to check cache performance within each node of the distributed memory machine.

A bubble domain storage system is described which has the best features of contiguous element bubble propagation systems and bubble lattice file systems. An array of magnetic bubble domains, such as a lattice, is moved along contiguous propagation patterns in response to the reorientation of a magnetic field in the plane of the bubble domain film. Adjacent rows of bubble domains in the array move in opposite directions to provide individual storage loops within the array. Information accessing can be achieved by the use of input/output registers similar to those used in other contiguous disk bubble domain storage systems. For example, the storage system can be a conventional major/minor loop organization using contiguous element propagation patterns for the storage registers and for the input/output registers. Every bit position in the storage registers is populated by a bubble domain where the average distance between adjacent bubble domains is less than that in a system where bubbles are isolated from one another. For example, the storage registers can be arranged so that the separation between adjacent bubble domains in the storage registers is 2-3 bubble diameters.

A magnetic bubble domain storage device comprising a plurality of storage shift registers and at least one major shift register, which serves to provide bubble domains to the storage register and to receive bubble domains from the storage registers. A novel transfer switch, or gate, is located between each of the storage registers and the major register, which is typically configured in the conventional major/minor loop type of storage organization. This transfer switch can be made using single level masking or multiple level masking and is characterized in that the locus of bubble domain propagation paths through the switch element generally defines the letter "Y". These propagation paths are from one arm of the Y to the other arm, from one arm of the Y to the stem or base portion, or the reverse where a bubble domain travels from the stem (base) of the Y to one of the arms of the Y. In a particular embodiment, the transfer switch is comprised of a Y-shaped magnetic element having a current carrying conductor which crosses the stem portion of the Y-shaped magnetic element. The particular path travelled by bubble domains through the transfer switch is determined by the presence or absence of a current through the conductor.

An improved magnetic bubble domain nucleator is provided which uses a magnetic wall, such as a charged wall, Neel wall, or Bloch wall, to assist nucleation. In a preferred embodiment, a magnetic charged wall is produced in an ion implanted region of a magnetic material with an in-plane magnetic field, and an applied nucleating magnetic field is produced by current in a conductor. The combination of the first magnetic field associated with the charged wall and the second magnetic field produced by current through the conductor is sufficient to nucleate a bubble domain in the magnetic medium whereas each of these fields acting alone is not sufficient for nucleation. Since the first magnetic field provides a component of the total nucleating field, the amount of nucleation current required in the conductor is reduced. Any structure that can be used to provide the magnetic charged wall, including ion implanted regions of a magnetic material, or an apertured layer of magnetically soft material is suitable in the practice of this invention. The structure for providing the second magnetic field is conveniently provided by a current carrying conductor, or by a magnetic element having a stray field associated therewith, or even by another magnetic bubble domain.

A method and apparatus for retrieving and organizing data using a self-organizing map in a parallel transaction data base system. With this invention, input records of data are represented as n dimensional vectors. Each of these vectors then compressed by eliminating zeros in the components of these vectors. Then, the self-organizing map algorithm is applied to the compressed input records to group the records into a number of clusters, where each cluster comprises a number of records having common input parameters.

A method for making a high density magnetic bubble domain system including the functions of read, write, storage, transfer, and annihilation. Only three masking steps are required, of which only one requires critical alignment. The proces makes use of the fact that magnetic disks can be placed on non ion implanted regions without adversely affecting the propagation properties of the implanted regions. Thus, the magnetic disks can be used to define ion implantation masks as well as for providing functions such as generation, propagation, reading, and annihilation. Magnetic elements for generation, storage and propagation, reading and annihilation are deposited in the same non-critical masking step, while all condutors used for writing, reading, and transfer are deposited by a single masking step requiring critical alignment.

A three-dimensional magnetic bubble device formed by depositing, on a flexible substrate, a plurality of pseudo-chips of amorphous metallic film capable of supporting magnetic bubbles. These pseudo-chips are interconnected by thin-film conductors also deposited on the flexible substrate. The substrate is then folded, on itself, a number of times to produce a three-dimensional magnetic bubble device. Optionally, a low temperature lamination step can be employed to complete the process. The folding step or steps, result in a number of layers, to which a common rotating magnetic field may be applied for propagation purposes.
