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： 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： Described herein are embodiments for end-to-end reinforcement learning based coreference resolution models to directly optimize coreference evaluation metrics. Embodiments of a reinforced policy gradient model are disclosed to incorporate reward associated with a sequence of coreference linking actions. Furthermore, maximum entropy regularization may be used for adequate exploration to prevent a model embodiment from prematurely converging to a bad local optimum. Experiments on datasets compared with state-of-the-art methods verified the effectiveness of embodiments.

摘要： According to one embodiment, a system receives, at a host channel manager (HCM) of a host system, a request from an application to establish a secure channel with a data processing (DP) accelerator, where the DP accelerator is coupled to the host system over a bus. In response to the request, the system generates a first session key for the secure channel based on a first private key of a first key pair associated with the HCM and a second public key of a second key pair associated with the DP accelerator. In response to a first data associated with the application to be sent to the DP accelerator, the system encrypts the first data using the first session key. The system then transmits the encrypted first data to the DP accelerator via the secure channel over the bus.

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.

摘要： A two-phase immersion cooling system for cooling electronics. The electronics are immersed in immersion tank filled with phase change liquid. As liquid evaporates due to heat generated by the electronics, it enters a vapor passageway that leads the vapor to a condenser situated remotely from the immersion tank. Upon condensing at the condenser, the condensed liquid is directed to a resupply tank, wherein the condensed liquid cools. When the level of the two phase liquid in the immersion tank drops below a set threshold, a pump is activated to deliver the condensed liquid from the resupply tank to the immersion tank. The immersion tank, vapor passageway and condenser are position inside a containment passageway. The containment passageway captures any vapor not entering the vapor passageway and direct such vapor to the condenser. An air mover generates pressure differential within the containment passageway to direct the vapor towards the condenser.
