Abstract: A method, a system and a computer program product for reconfiguring hardware network topology including graphics processor units (GPU) and central processing unit (CPU) interconnectivity on or across compute nodes of a rack-mount server. The re-configurability is based on detected thermal throttling or thermal hot spots when running workloads. For network re-configurability, a user can directly connect high-speed cable links between CPU/GPU connectors and between GPU/GPU connectors on a same PCB compute node, or across two PCB compute nodes as suggested by a control processor to avoid thermal and power hotspots when running the workload. The method recommends and generates a system map of the hardware network topology known to avoid/mitigate thermal throttling, and instructs a configuration of CPUs and GPUs such that GPUs are assigned to workloads at locations for mitigating thermal throttling based on detected thermal hot spots and power hot spots to optimize workload performance.

Abstract: A light weight extruder (20) is suitable for high production, in-line extrusion of flowable materials with high precision in the placement and control of the extruded material. The extruder uses a high torque hydraulic motor (72) to drive a feed screw (88) in dispensing highly viscous but flowable material through an extrusion die (126) of preselected configuration. A plurality of heating bands (114-118) surrounding the barrel (86) of the extruder provide precise control over the material temperature at the point of extrusion. In an alternate embodiment, an injection nozzle (120a) is provided with a plurality of independently controllable extrusion dies (128, 130, 132). The extruder is sufficiently light and manipulable such that it can be mounted on the end of the arm of a robot (122).
