Hierarchical power distribution in large scale computing systems
Techniques for managing power distribution amongst processors in a massively parallel computer architecture are disclosed. The techniques utilize a hierarchy that organizes the various processors of the massively parallel computer architecture. The hierarchy groups numbers of the processors at the lowest level. When processors complete tasks, the power assigned to those processors is distributed to other processors in the same group so that the performance of those processors can be increased. Hierarchical organization simplifies the calculations required for determining how and when to distribute power, because when tasks are complete and power is available for distribution, a relatively small number of processors are available for consideration to receive that power. The number of processors that are grouped together can be adjusted in real time based on performance factors to improve the trade-off between calculation speed and power distribution efficacy. |

Valve stem seal
A valve stem seal exhibits superior workability of mounting of a reinforcing ring to a valve stem guide and enables the reinforcing ring to be fixed to the valve stem guide in a stable manner. A reinforcing ring is mounted to a valve stem guide by fitting a cylindrical portion to the valve stem guide from a side opposite to an inward flange portion. The cylindrical portion includes a slit extending linearly in a circumferential direction and a locking protrusion that is provided on a side opposite to the inward flange portion with respect to the slit and that is to be locked by a locking recess formed in the valve stem guide. The locking protrusion is constituted by a curved portion that is gradually recessed radially inward from the side opposite to the inward flange portion with respect to the slit to a position that reaches the slit. |

Thermal energy recovery device
Provided is a thermal energy recovery device in which a site of a circulation flow path between an evaporated portion and an expander can be avoided having too high temperature upon stoppage of power recovery by a power recovery machine. The thermal energy recovery device includes an evaporator (10), an expander (12), a power recovery machine (14), a condenser (16), a pump (18), a circulation flow path (20), a cooling flow path (30) for supplying working medium of liquid phase flowing out of the pump (18) partially to a site of the circulation flow path (20) between the evaporator (10) and the expander (12), an on-off valve (V1) provided in the cooling flow path (30), and a control unit (40), in which upon reception of a stop signal for stopping power recovery by the power recovery machine (14), the control unit (40) opens the on-off valve (V1). |

Bearing housing and an exhaust gas turbocharger with such a housing
A bearing housing for an exhaust gas turbocharger may include a bearing housing cover arranged on a bearing housing wall. The bearing housing cover may include a penetrating rotation-symmetrical sealing recess with a centre axis and may have a locating surface facing the bearing housing wall and radially extending from the centre axis. The bearing housing may include a sealing bush arranged in at least one region of the sealing recess. The sealing bush may have a stop surface arranged opposite the locating surface and may include a penetrating shaft recess disposed rotation-symmetrical relative to the centre axis. The bearing housing cover may further include an at least partly circulating groove disposed on the locating surface radially spaced from the centre axis. The groove may include a drainage region arranged below the centre axis and extending from the centre axis radially to an outside. |
