Techniques for modeling elastic rods in position-based dynamics frameworks
In one embodiment of the present invention, a position-based dynamics (PBD) framework provides realistic modeling and simulation for elastic rods. In particular, the twisting and bending physics of elastic rods is incorporated into the PBD framework. In operation, an elastic rod model generator represents the center line of an elastic rod as a polyline of points connected via edges. For each edge, the elastic rod model generator adds a ghost point to define the orientation of a material frame that encodes the twist of the edge. Subsequently, a PBD simulator solves for positions of both points and ghost points that, together, represent the evolving position and torsion of the elastic rod. Advantageously, the ghost points enable more realistic animation of deformable objects (e.g., curly hair) than conventional PBD frameworks. Further, unlike force based methods, elastic rod simulation in the PBD framework performs acceptably in environments where speed is critical. |

Identification and classification of write stream priority
Increases in efficiency of storage device operation may be realized if the limited number of available high-priority communication channels are better optimized and assigned among hosts that may best utilize them. This assignment can occur in response to an evaluation of the overall zone usage or by received metadata and/or indicia from the host. The storage device may periodically, or in response to a command, reevaluate the assigned priority status of each communication channel and associated host/zone pair. For example, the storage device may demote or remove a communication channel from high-priority to low-priority. This process can be continued during a preconfigured time window which can be adjusted before, during, or after priority evaluation. The continuous operation of this process can allow for adjustments being made to priority levels within the storage device that may further increase total operational efficiency. |

Invalidation of a target realm in a realm hierarchy
An apparatus has processing circuitry for performing data processing in response to software processes and memory access circuitry for enforcing ownership rights for memory regions. A given memory region is associated with an owner realm specified from a multiple realms with each realm corresponding to a portion of at least one software process. The owner realm has a right to exclude other realms from accessing data stored in the given memory region (including realms executed at a higher privilege level). The realms are managed according to a realm hierarchy in which each realm other than a root realm is a child realm initialised in response to a command triggered by its parent realm. In response to an invalidation command, a realm management unit makes the target realm and any descendant realm of the target realm inaccessible to the processing circuitry. |
