    摘要: An information technology (IT) equipment cooling system includes a coolant unit to be coupled to an electronic rack, the coolant unit to supply a two phase liquid coolant to one or more IT equipment cooling sets mounted within on an electronic rack. Each of the one or more IT equipment cooling sets includes an IT unit having one or more pieces of IT equipment configured to provide IT services and is at least partially submerged within the two phase liquid coolant, where, while the IT equipment provides the IT services, the IT equipment generates heat that is transferred to the two phase liquid coolant thereby causing at least some of the two phase liquid coolant to turn into vapor phase. The IT equipment cooling set includes an IT condensing unit having a condenser positioned above the IT unit and the condenser is to condense the vapor back into liquid state.

    摘要: A rack cooling system includes a primary cooling condenser and a secondary cooling condenser. The primary cooling condenser is positioned above servers of a server rack and the secondary cooling condenser is position above the primary cooling condenser. Each of the severs, the primary cooling condenser, and the secondary cooling condenser is connected to a liquid manifold via one of a plurality of liquid ports on the liquid manifold, and to the vapor manifold via one of a plurality of vapor ports on the vapor manifold. A cooling capacity of the rack cooling system can be extended by switching on a vapor flow between the secondary cooling condenser and the primary cooling condenser using a first valve on the vapor manifold. Further, a second valve on a primary cooling loop can be used to control cooling fluid flowing into the secondary cooling condenser after the first valve is trigged open.

    摘要: A method for information processing for accelerating neural network training. The method includes: acquiring a neural network corresponding to a deep learning task; and performing iterations of iterative training on the neural network based on a training data set. The training data set includes task data corresponding to the deep learning task. The iterative training includes: processing the task data in the training data set using a current neural network, and determining, based on a processing result of the neural network on the task data in a current iterative training, prediction loss of the current iterative training; determining a learning rate and a momentum in the current iterative training; and updating weight parameters of the current neural network by gradient descent based on a preset weight decay, and the learning rate, the momentum, and the prediction loss in the current iterative training. This method achieves efficient and low-cost deep learning-based neural network training.

    摘要: Described herein are embodiments for a feature-scattering-based adversarial training approach for improving model robustness against adversarial attacks. Conventional adversarial training approaches leverage a supervised scheme, either targeted or non-targeted in generating attacks for training, which typically suffer from issues such as label leaking as noted in recent works. Embodiments of the disclosed approach generate adversarial images for training through feature scattering in the latent space, which is unsupervised in nature and avoids label leaking. More importantly, the presented approaches generate perturbed images in a collaborative fashion, taking the inter-sample relationships into consideration. Extensive experiments on different datasets compared with state-of-the-art approaches demonstrate the effectiveness of the presented embodiments.

    摘要: According to one embodiment, a method is provided for video repainting performed by at least one processor of a computer device. The method includes receiving a video sequence having one or more image frames; detecting presences of a target object within the one or more image frames and determining pose condition and style shift of the detected objects; generating content representing a replacement object for the one or more image frames by applying the corresponding pose condition and style shift to the replacement object; and repainting the detected target object in the one or more image frames with the generated content.

    摘要: A fluid distribution apparatus for servers mounted onto a rack. The apparatus includes one or more pairs of distribution units that are rotationally symmetric and are attached to each other to form the pair. Each of the distribution units includes a main supply port and main return port that are connected to the rack's fluid manifolds. Each of the distribution units also includes plurality of supply and return connectors that connect to the servers. A pump in each of the distribution units delivers fluid from the rack's fluid manifolds to the servers for cooling. Each server is connected to fluid ports on both distribution units, so as to provide full redundancy. A controller receives signals form the servers and sends operation signals to the pumps to control the fluid delivery for cooling the servers.
