One of the plurality of processing entities is allocated for execution of a critical task. In response to the allocating of one of the plurality of processing entities for the execution of the critical task, other processing entities of the plurality of processing entities are folded. The critical task utilizes the local cache of the other processing entities that are folded, the shared memory, and the shared cache, in addition to the local cache of the processing entity allocated for the execution of the critical task.

Abstract: A plurality of ordered lists of dispatch queues corresponding to a plurality of processing entities are maintained, wherein each dispatch queue includes one or more task control blocks or is empty. A determination is made as to whether a primary dispatch queue of a processing entity is empty in an ordered list of dispatch queues for the processing entity. In response to determining that the primary dispatch queue of the processing entity is empty, a task control block is selected for processing by the processing entity from another dispatch queue of the ordered list of dispatch queues for the processing entity, wherein the another dispatch queue from which the task control block is selected meets a threshold criteria for the processing entity.

Abstract: Provided are techniques for detecting a type of storage adapter connected to an Input/Output (I/O) bay and miscabling of a microbay housing the storage adapter. Under control of an Input/Ouput (I/O) bay, cable sidebands are driven high for a predetermined period of time. It is determined whether a cable sidebands response has been detected that indicates that the cable sidebands have been driven low. In response to determining that the cable sidebands response has been detected, it is determined that the I/O bay is connected to a first storage adapter supporting a first protocol for the cable sidebands. In response to determining that the cable sidebands response has not been detected, it is determined that the I/O bay is connected to a second storage adapter supporting a second protocol for the cable sidebands. Moreover, I/O bay and port numbers stored by the microbay are used to determine miscabling.

Abstract: A process and apparatus provides alternative hydrotreating reactor trains for hydrotreating a hydrocarbon stream. One hydrotreating reactor train is smaller than the other and the smaller train comes on stream to allow replacement or regeneration of catalyst in the larger train. A sulfide system also sulfides the catalyst volume in the reactor train that is off stream to prepare it for renewed hydroprocessing of feed when back on stream. The process and apparatus can be used to keep hydroprocessing reactors on stream to continuously provide feed to an FCC unit which has a longer period before shut down.

Abstract: The disclosed embodiments relate to a computer system with a cache memory that supports tagless addressing. During operation, the system receives a request to perform a memory access, wherein the request includes a virtual address. In response to the request, the system performs an address-translation operation, which translates the virtual address into both a physical address and a cache address. Next, the system uses the physical address to access one or more levels of physically addressed cache memory, wherein accessing a given level of physically addressed cache memory involves performing a tag-checking operation based on the physical address. If the access to the one or more levels of physically addressed cache memory fails to hit on a cache line for the memory access, the system uses the cache address to directly index a cache memory, wherein directly indexing the cache memory does not involve performing a tag-checking operation and eliminates the tag storage overhead.

Abstract: A plurality of processing entities are maintained in a processor complex. In response to determining that a task is a critical task, the critical task is dispatched to a scheduler, wherein it is preferable to prioritize execution of critical tasks over non-critical tasks. In response to dispatching the critical task to the scheduler, the scheduler determines which processing entity of the plurality of processing entities has a least amount of processing remaining to be performed for currently scheduled tasks. Tasks queued on the determined processing entity are moved to other processing entities, and the currently scheduled tasks on the determined processing entity are completed. In response to moving tasks queued on the determined processing entity to other processing entities and completing the currently scheduled tasks on the determined processing entity, the critical task is dispatched on the determined processing entity.

Abstract: It is possible to reduce the overhead associated with downlink channel estimation in massive Multiple-Input-Multiple-Output (MIMO) networks by processing training sequences according to a transformation matrix. The transformation matrix maps a generic dictionary to a non-generic dictionary associated with an antenna geometry of a MIMO antenna array. The transformation matrix can be computed based on the two dictionaries. In one embodiment, the training reference signal is precoded to obtain a precoded training reference signal, which is then transmitted over a MIMO antenna array. The training precoder used to precode the training reference signal is designed according to the transformation matrix to mitigate a dependence that the training reference signal transmission has on the antenna geometry.

Abstract: Systems and methods described herein can provide clinicians with a dental office management service that can programmatically provide treatment recommendations and streamline the patient record building process. These systems and methods can enable clinicians to select from a short list of recommended treatments based on the existing condition and pathology of a tooth, for example, as the dentist is giving instructions and treatment recommendations. A list of recommended treatments for a patient may be automatically compiled based on the treatment recommendations selected by the clinician as the dentist was examining the patient's teeth one by one. Further, systems and methods described herein can enable clinicians to take notes and thereby build a patient record efficiently using one or more completed treatment templates.

Abstract: A single light emitting diode (LED) structure includes an array of spaced discrete light emitting zones separated by isolation areas. Each emitting zone includes an epitaxial structure configured to emit an emitting light having a particular wavelength over an effective emission area. In addition, the effective emission area for each emitting zone can be geometrically defined and electrically configured to provide a desired light intensity. For example, each effective emission area can have a selected size and spacing depending on the application and light intensity requirements. Each emitting zone also includes a wavelength conversion member on its effective emission area configured to convert an emitting wavelength of the emitting light to a different color. The single (LED) structure can include multiple colors at different zones to produce a desired spectra or design.
