A memory system architecture / interconnect topology includes a configurable width buffered memory module having a configurable width buffer device with at least one switch element. A buffer device, such as a configurable width buffer device, is positioned between or with at least one integrated circuit memory device positioned on a substrate surface of a memory module, such as a DIMM.

Systems and methods for scheduling jobs in a multiprocessor machine are disclosed. The status of resources in the multiprocessor machine is periodically determined. The status indicates the resources available to execute jobs. This information is accumulated by the topology-monitoring unit and provided to the topology library. The topology library also receives a candidate host list which lists all resources available to execute the job being scheduled based on non-trivial scheduling. The topology library unit generates a free map F indicating the interconnection of the resources available to execute the job. The topology monitoring unit matches jobs to the resources available to execute the jobs, based on resource requirements including shape requirements indicative of interconnections of resources required to execute the job. The topology monitoring unit dispatches the job to the portion of the free map F which matches the shape requirements of the job.

The invention is directed towards method and apparatus that consider diagonal wiring in placement. Some embodiments of the invention are placers that use diagonal lines in calculating the costs of potential placement configurations. For instance, some embodiments estimate the wirelength cost of a placement configuration by (1) identifying, for each net in a net list, a bounding box that encloses all the circuit elements of the net, (2) computing an attribute of each bounding box by using a line that can be completely or partially diagonal, and (3) computing the wirelength cost estimate based on the computed attributes. To estimate the wirelength cost of different placement configurations, other embodiments construct connection graphs that model the net interconnect topologies. These connection graphs can have edges that are completely or partially diagonal. Other embodiments use diagonal lines to measure congestion costs of potential placement configurations. For instance, some placers use diagonal lines as cut lines that divide the IC layout into regions. These placers then generate congestion-cost estimates by measuring the number of nets cut by the diagonal cut lines.

Large area, high current, lateral GaN power transistors are implemented using an on-chip interconnect topology wherein the transistor is arranged as an array of sections, each section comprising a set of transistor islands; gate and source buses that form each gate drive loop have substantially the same track widths; the source bus runs over or under the gate bus, and the tracks are inductively coupled to provide flux cancellation in the gate drive loop, thereby reducing parasitic inductances. The gate delay in each gate drive loop is reduced, minimizing the gate drive phase difference across the transistor. An overlying current redistribution layer preferably has a track width no greater than that of the underlying source and drain buses, for efficient coupling. This topology provides improved scalability, enabling fabrication of multi-section, large scale, high current lateral GaN transistors with reduced gate drive loop inductance, for improved operational stability.

A systems power distribution tool integrates the design of the power source and distribution network to provide a robust interconnect topology and power source. This is accomplished with a machine of one or more computing devices configured as a systems power distribution tool. The tool “pulls” load current from the source through interconnects to the loads. This allows the interconnects to be designed to satisfy derating conditions for worst case voltage and current conditions and the power source to be designed to source the loads under actual conditions without margin stacking.
