  • Publication number: 20230419119
    Abstract: Methods, systems, and apparatuses include determining a set of data. The set of data includes multiple numerical ranges associated with an embedding and an attribute. The numerical range is sampled to obtain a sample value which is also associated with the embedding and the attribute. A set of sample value training data is generated, the set including the sample value, the associated embedding, and the associated attribute. A trained neural network prediction model is generated by applying a prediction model to the set of sample value training data. A set of input data is applied to the trained neural network prediction model. An output is determined by the trained neural network prediction model based on the set of input data. The output is a predicted range of values based on an output mean and an output standard deviation.

  • Patent number: 9836406
    Abstract: A method, system, and computer-readable medium for evicting cache lines that includes determining that a first cache line is to be evicted from a first Last Level Cache (LLC) partition of a partitioned LLC, and sending, based on the determination, a first notification to a second LLC partition of the partitioned LLC. The method may also include receiving, in response to the first notification, an available indication indicating that the second LLC partition is available as a designated victim cache partition; performing a selection of the second LLC partition as the designated victim cache partition; and evicting the first cache line to the second LLC partition based on the selection.

  • Patent number: 9836326
    Abstract: A method and system for allocating data streams that includes receiving, at an allocator, a data stream. The data stream includes a memory address and data associated with the memory address. The method also includes examining, by the allocator, the data stream to make a determination that the data stream is a soft allocating data stream, and then sending, from the allocator based on the determination, a plurality of write probes to a plurality of caches, wherein each write probe of the plurality of write probes includes at least part of the memory address. Additionally, the method includes receiving, at the allocator in response to a write probe of the plurality of write probes, a cache line present acknowledgement from a cache of the plurality of caches, and directing, by the allocator in response to the cache line present acknowledgement, the data of the data stream to the cache.

  • Patent number: 9808193
    Abstract: An apparatus and method for inflicting brain injury on a laboratory animal that employs a platform for supporting the laboratory animal. The platform defines an opening for positioning the head of the laboratory animal over the opening. A projectile is launched from a projectile launching device orientated below the opening of the platform. The projectile launching device has a means for propelling the projectile directly at and/or through the opening of said platform, thereby inflicting brain injury on the animal via either a pressure wave or concussive impact of the projectile. Without helmet, direct impact of the projectile results in severe traumatic brain injury. Use of helmet protects animals from skull fracture, subdural hematoma, intracerebral hemorrhage and contusion yet produces mild concussion-like pathology.
