摘要： A cooling device for cooling a chip, a server with such a cooling device, and a rack are disclosed. The cooling device comprises a cooling layer that is divided into multiple cooling regions; and an internal region that includes a vapor separation core. Two-phase coolant that enters a first cooling region of the cooling layer is converted to mixed fluid due to heat extracted from a corresponding region of the chip. The mixed fluid is elevated to the vapor separate core, which separates vapor from liquid in the mixed fluid. The vapor exits the cooling device while the liquid is transported to a second cooling region in the cooling layer. The cooling device can be used with a condenser in a server to form an internal server loop, and can be connected to a rack to form a main fluid loop. The two coolant recirculation loops are used together to maintain a predetermined liquid balance in the cooling device.

摘要： A cooling unit includes a channel frame assembled to a server chassis to form a region enclosing an electronic chip that is disposed on a server board contained within the server chassis, an inlet port coupled to a first side of the channel frame to receive a coolant fluid, an outlet port coupled to a second side of the channel frame for coolant fluid in either a liquid phase or a vapor phase to exit the channel frame, and an internal structure disposed on an inner surface of the channel frame between the inlet port and the outlet port. The internal structure guides the coolant fluid flow and/or distribution along a surface of the electronic chip, where the electronic chip transfers heat to the coolant fluid to cause a portion of the coolant fluid to change from a liquid to a vapor phase.

摘要： An electronic rack includes an array of server blades arranged in a stack. Each server blade contains one or more servers and each server includes one or more processors to provide data processing services. The electronic rack includes a coolant distribution unit (CDU) and a rack management unit (RMU). The CDU supplies cooling liquid to the processors and receives the cooling liquid carrying heat from the processors. The CDU includes a liquid pump to pump the cooling liquid. The RMU is configured to manage the operations of the components within the electronic rack such as CDU, etc. The RMU includes control logic to determine an optimal pump speed to minimize the total power consumption of the pump, acceleration servers and the host servers, based on the one or more parameters and the association between temperature and power consumption of the acceleration servers and the host servers. The RMU then controls the liquid pump based on the optimal pump speed.

摘要： Neural Architecture Search (NAS) is a laborious process. Prior work on automated NAS targets mainly on improving accuracy but lacked consideration of computational resource use. Presented herein are embodiments of a Resource-Efficient Neural Architect (RENA), an efficient resource-constrained NAS using reinforcement learning with network embedding. RENA embodiments use a policy network to process the network embeddings to generate new configurations. Example demonstrates of RENA embodiments on image recognition and keyword spotting (KWS) problems are also presented herein. RENA embodiments can find novel architectures that achieve high performance even with tight resource constraints. For the CIFAR10 dataset, the tested embodiment achieved 2.95% test error when compute intensity is greater than 100 FLOPs/byte, and 3.87% test error when model size was less than 3M parameters. For the Google Speech Commands Dataset, the tested RENA embodiment achieved the state-of-the-art accuracy without resource constraints, and it outperformed the optimized architectures with tight resource constraints.
