Abstract: Systems for self-configuring health monitoring instrumentation for clustered storage platforms. Master and slave health modules implement a health monitoring system in a clustered virtualization environment comprising a plurality of nodes of the cluster with an installed health module instance running on the nodes. The health module system may gather and analyze data on a node level and at a cluster level to manage the cluster. The cluster health module system observes I/O commands issued to, and I/O command responses returned from, a common storage pool. Health data is stored in the storage pool.

Abstract: Measurements comprising time-series stimuli and time-series responses of a computing platform that has executed a first set of jobs are collected over a first time period. The measurements are used to form a query-able predictive model pertaining to resource usage demand predictions for the first set of jobs. A second set of job records describe a second set of jobs to be invoked in a second time period. The predictive model is queried to determine a likelihood to complete by the predicted finish time based on resource usage demand predictions for the first set of jobs. A weighting factor related to a likelihood to complete the second set of jobs by a particular time is calculated. A reward value based on the weighting factor is assigned to respective jobs in the second set of jobs. Some of the second set of jobs are rescheduled, based on a then-current reward value.

Abstract: In one embodiment, a method may comprise receiving a query to search for one or more entities of the data center, the query including one or more query tokens. The method may then identify one or more entity-type nodes corresponding to the query, and rank the entity-type nodes based on a score determined for each of the identified entity-type nodes. For at least a portion of the ranked entity-type nodes, the method may generate a structured query associated with each of the entity-type nodes based at least in part of one or more activity-type nodes connected to each of the entity-type nodes. Then, the method may retrieve, based on the structured queries, results from one or more databases.

Abstract: In one embodiment, a system includes a cluster of host machines implementing a virtualization environment. Each host machine a hypervisor, a user virtual machine (UVM), a connection manager, an I/O controller, and a virtual disk. The virtual environment may include storage devices and may be accessible by all of the I/O controllers. A management module of the virtualization environment may display a graphical user interface that includes an alert rule configuration interface, which may be operable to configure one or more alert policies each associated with an operating status of a component of the virtualization environment. The management module may receive inputs associated with the alert policies. The management module may update the alert policies in accordance with the inputs.

Abstract: The present invention is method for permanently compressing tissues in the body. The method employs a compression device made of a spring and a flexible sheet that cooperate to form a compressive envelope around the desired tissue. The spring is preferably Z-shaped or a coil. The sheet is made of a flexible material and the material is preferably elastic. The sheet is preferably a biocompatible elastic material, such as a mesh made of stainless steel or a woven or non-woven elastomer. The method is minimally invasive because it deploys the compression device through the patient's skin directly to the tissue, as opposed to through catheterization or open invasive surgery, such as open-heart surgery. The preferred use is for compressing the left atrial appendage to prevent clots from forming and circulating, thereby preventing strokes.

In connection with processing connections with a timer thread, a plurality of connections are processed with a plurality of timer threads. A plurality of hash buckets are provided, and each connection is mapped to one of the hash buckets. Further, each hash bucket is assigned to a processor timer thread based on a workload thereof.

Abstract: Enhanced memory management schemes are presented to extend the flexibility of using either internal or external packet memory within the same network device. In the proposed schemes, the user can choose either static or dynamic schemes, both or which are capable of using both internal and external memory, depending on the deployment scenario and applications. This gives the user flexible choices when building unified wired and wireless networks that are either low-cost or feature-rich, or a combination of both. A method for buffering packets in a network device, and a network device including processing logic capable of performing the method are presented.

Abstract: Methods and systems for providing confidentiality and/or integrity to fragmented packet transmissions, without reassembly of the fragments, across wired and wireless communications networks are disclosed. Encryption of a first fragmented packet can be performed by using an initial encryption state variable and keying material resulting in a first ciphertext fragment and a first encryption state variable. Then encryption of a second fragments packet can be performed by using the first encryption state variable and the keying material resulting in a second ciphertext fragment. Decryption of fragments can be performed in a similar manner as encryption. Computation of a message authentication code can be performed by computing a first hash state value for a first block size of bytes of a first packet fragment using an initial hash state value, and storing the first hash value and a first set of remainder bytes of the first packet fragment.

Abstract: An apparatus and graphical method for tracking image volume review is provided. An image volume data set is stored in a memory and selected portions of the image volume data set is displayed on a human readable display. A mapping of the displayed portion of the image volume data set is performed relative to a volume completion data set. The volume completion data set with the first portion thereof identified according to the mapping is colorized using a shading function to visually differentiate first portions of the volume completion data set reviewed by a radiologist from remaining portions of the volume completion data set. In that way, a complete review of the image volume can be conducted without missing portions thereof and without redundancy.
