In a computer-implemented method, an electronic communication from a first computing machine is received and includes a power value and one or more priority values. The power value represents a request for a power allotment expected to be used during a predetermined time and the priority values represent priorities of tasks expected to be executed during the predetermined time. A score for the request is calculated using a scoring function and the received priority values as inputs to the scoring function. The score is compared to one or more other scores respectively associated with requests for power allotments from other computing machines and previously calculated using the scoring function following receipt of one or more electronic communications each including a power value and one or more priority values. A top-ranked score is identified and an electronic communication is sent to the associated computing machine granting the requested power allotment.

A data center cooling system includes an evaporative cooling system. The evaporative cooling system includes fans configured to circulate outside air at ambient conditions through an entry zone of a data center, and atomizers positioned upstream of the entry zone configured to spray atomized water into the circulating outside air. The atomized water evaporates in an evaporation zone and cools the outside air to produce cooled air, which is directed through racks of computers positioned downstream of the evaporation zone.
A method of providing cooling by a cooling system to a computer data center. The method includes providing a plurality of air-and-water radiators and one or more chillers, the chillers each having a first side in fluid communication with a chilled water loop and a second side in communication with a condenser water loop. The method also includes circulating a first portion of return water coming from the computer data center to a first subset of the air-and-water radiators and through the condenser water loop, circulating a second portion of the return water from the computer data center to a second subset of the air-and-water radiators and through the chilled water loop, and circulating the first portion and the second portion of the return water to the computer data center as cooled supply water.
A data center includes a bank of computers, a plenum in fluid communication with the bank of computers, and a chimney in fluid communication with the plenum. The chimney is configured to use heat from the bank of computers to sufficiently lower an air pressure in the plenum to cause an air flow across the bank of computers sufficient to cool the bank of computers for normal operation.
A system for cooling air in a data center includes a data center having electronic equipment in operation, a cooling water source, and a plurality of on-floor cooling units. The cooling water source is configured to retain at maximum capacity a total amount of water. Each on-floor cooling unit is configured to cool air heated by a portion of the electronic equipment in the data center using water from the cooling water source. The total amount of water is insufficient to maintain a leaving air temperature of each on-floor cooling unit below an inside setpoint when a temperature outside of the data center is above a predetermined external temperature.

Apparatus and associated method and computer program products involve a highly efficient uninterruptible power distribution architecture to support modular processing units. As an illustrative example, a modular processing unit includes an integrated uninterruptible power system in which a PFC-boost AC-to- DC conversion occurs between the utility AC grid and the processing circuit (e.g., microprocessor) loads. In an illustrative data center facility, a power distribution architecture includes a modular array of rack-mountable processing units, each of which has processing circuitry to handle network-related processing tasks. Associated with each modular processing unit is an integrated uninterruptible power supply (UPS) to supply operating power to the network processing circuitry. Each UPS includes a battery selectively connectable across a DC bus, and a AC-to-DC rectifier that converts an AC input voltage to a single output voltage on the DC bus. The regulated DC bus voltage may be close to the battery's fully charged voltage.
