Abstract: An apparatus for cooling a plurality of rack-mountable servers containing heat generating electronic components in a server room including a dielectric liquid cooling apparatus located inside the tank and a secondary cooling apparatus comprising a remote heat exchanger and at least one pump. The volume of dielectric liquid coolant comprises at least one passage in the tank that is outside of the vertically oriented rack-mountable servers. When the at least one pump is operated to move the dielectric liquid coolant vertically across the heat producing components on the vertically oriented servers, a circuit is formed in which a first portion of dielectric liquid coolant is moved vertically upward across the heat producing components on the vertically oriented servers and then downward outside of the rack mountable servers in the at least one passage, while a second portion of the dielectric liquid coolant flows out of the tank.

Abstract: Described herein are technologies for application authentication and/or data encryption without stored pre-shared keys. In one resource controller, a processing device receives an application identifier (ID) from the application. The processing device provides a current nonce responsive to the application ID and provides the application access to the system resource responsive to determining that a hash of a current key received from the application equals a current tag. The current key is generated by the application based on code of the application and the current nonce. The current tag was previously provided from the application to the resource controller. The current tag can also be hashed by the application using the current key.

Abstract: A first address bus may be located in an upper layer of an integrated circuit that is associated with a memory and a memory controller. The first address bus may receive a first portion of a memory address. A second address bus may be located in a lower layer of the integrated circuit where the second address bus is to receive a second portion of the memory address. Furthermore, a data bus may be located in an intermediate layer where the data bus is to receive data corresponding to the memory address from the memory and may transmit the data to the memory controller. The intermediate layer may be between the upper layer and the lower layer. A layout of the signals of the data bus may vertically overlap with a layout of signals of the first address bus and a layout of signals of the second address bus.

Abstract: A first timing reference signal and a second timing reference signal are sent to a memory device. The second timing reference signal has approximately a quadrature phase relationship with respect to the first timing reference signal. A plurality of serial data patterns are received from the memory device. The transitions of the first timing reference and the second timing reference determining when transitions occur between the bits of the plurality of data patterns. Timing indicators associated with when received transitions occur between the bits of the plurality of data patterns are received from the memory device. The timing indicators are each measured using a single sampler. Based on the timing indicators, a first duty cycle adjustment for the first timing reference signal, a second duty cycle adjustment for the second timing reference signal, and a quadrature phase adjustment are determined and applied.
