摘要:
System, method, and apparatus for improving the performance of collective operations in High Performance Computing (HPC). Compute nodes in a networked HPC environment form collective groups to perform collective operations. A spanning tree is formed including the compute nodes and switches and links used to interconnect the compute nodes, wherein the spanning tree is configured such that there is only a single route between any pair of nodes in the tree. The compute nodes implement processes for performing the collective operations, which includes exchanging messages between processes executing on other compute nodes, wherein the messages contain indicia identifying collective operations they belong to. Each switch is configured to implement message forwarding operations for its portion of the spanning tree. Each of the nodes in the spanning tree implements a ratcheted cyclical state machine that is used for synchronizing collective operations, along with status messages that are exchanged between nodes. Transaction IDs are also used to detect out-of-order and lost messages.

摘要:
A food and beverage dispensing system having a main dispenser for holding and dispensing a food or beverage mixture comprised of water and dry concentrate. A replenishing dispenser is connected to and stationed entirely independent of the main dispenser. The replenishing dispenser has a mixing valve for automatically and periodically blending proportioned amounts of the water and dry concentrate to form the food or beverage mixture. The mixing valve intermittently dispenses a controlled amount of the food or beverage mixture therefrom. The replenishing dispenser also has a reservoir located below the mixing valve for receiving, holding and periodically delivering a food or beverage mixture to the main dispenser in accordance with the amount of food or beverage mixture dispensed from the main dispenser.

A gas washing device includes a permeable gas sink, a gas inlet for supplying gas through the sink to a molten metal container, a gas flow meter positioned upstream of the gas inlet, and a further gas sink having a gas permeability greater than that of the first-mentioned gas sink and positioned between the gas inlet and the first-mentioned gas sink.
摘要:
A post mix liquid dispensing system for combining a concentrate with a diluent including an arrangement in which the diluent is self-contained within the system, independent of any external diluent source such that the system is portable with respect to the diluent and concentrate. A concentrate pump having a pair of rollers cooperating with a rotor rotatably driven within a fixed race by a motor and spring biased into and out of clamping engagement with a conduit carrying the concentrate forces concentrate through the conduit during rotation of the rotor. The concentrate pump interacts with a diluent pump to transfer concentrate and diluent into a mixing valve for dispensing of a food or beverage of uniform consistency.
