Abstract: Systems and methods are provided for detecting anomalies on multiple layers of a computer system, such as a compute server. For example, the system can detect anomalies from the lower firmware layer up to the upper application layer of the compute server. The system collects train data from the computer system that is under testing. The train data includes features that affect performance metrics, as defined by a selected benchmark. This train data is used in training machine learning (ML) models. The ML models create a train snapshot corresponding to the selected benchmark. Additionally with every new release, a test snapshot can be created corresponding to the selected benchmark or workload. The system can detect an anomaly based on the train snapshot and the test snapshot. Also, the system can recommend tunings for a best set of features based upon data collected over generations of compute server.

Abstract: An Adaptive and Distributed Tuning System (ADTS) includes a distributed framework for full-stack performance tuning of workloads. Given a large search space, the framework leverages domain-specific contextual information, in the form of probabilistic models of the system behavior, to make informed decisions about which configurations to evaluate and, in turn, distribute across multiple nodes to converge rapidly to best possible configurations.

Abstract: Components for positioning devices that can be welded together via a resistance welding process. The one component exhibits at least one circulatory embossing that protrudes beyond its surface toward the connection side and that engages in the complementary recess of the other component. The embossing can be pressed into the recess during the resistance welding process. At least one of the components exhibits on the side spaced from the circulatory embossing additional embossings that limit the impression depth of the circulatory embossing of the one component into the recess of the other component. This is done such that the surfaces facing each other of the two components maintain a fixed distance to one another.

Abstract: A method and a tool are provided for producing structural parts from sheet metal which have a vault-structured stiffening zone and adjacent, flat connection zones. The starting point for producing these structural parts is vault-structured blanks which are smoothed in the region of the connection zones in the course of the forming, whereas the vault structure is retained unchanged in the region of the stiffening zone. These structural parts are produced by an embossing tool which has a die and a two-piece punch including of a fixing punch and a forming punch. In the process, the blank is first of all fixed relative to the fixing punch in the region of the vault-structured stiffening zone by a fixing element which is in a leading position with respect to the die. The connection zones are then shaped between the punch and the forming punch.

Abstract: The support structure of a body for a motor, vehicle is assembled from large-size partial modules. Two partial modules connected to each other comprise support sections and wall and/or floor sections connected thereto. Support sections of one partial module are connected to associated support sections of the other partial module at abutment points. In order to design a highly stressed connection between partial modules of the support structure in a very stable and simple manner, the support sections of the two partial modules, which support sections are assigned in each case to one another, are assembled to form a continuous support. Abutting surfaces of the assembled support sections run obliquely with respect to the direction of extent of the support. This oblique profile of the abutting surfaces creates a connection over a very large area in relation to the cross section of the support, which ensures an extremely stable connection of the two parts to each other.
