Patent number: 11327900Abstract: Multiprocessor clusters in a virtualized environment conventionally fail to provide memory access security, which is frequently a requirement for efficient utilization in multi-client settings. Without adequate access security, a malicious process may access what might be confidential data that belongs to a different client sharing the multiprocessor cluster. Furthermore, an inadvertent programming error in the code for one client process may accidentally corrupt data that belongs to the different client. Neither scenario is acceptable. Embodiments of the present disclosure provide access security by enabling each processing node within a multiprocessor cluster to virtualize and manage local memory access and only process access requests possessing proper access credentials. In this way, different applications executing on a multiprocessor cluster may be isolated from each other while advantageously sharing the hardware resources of the multiprocessor cluster.Type: GrantFiled: July 23, 2020Date of Patent: May 10, 2022Assignee: NVIDIA CorporationInventors: Samuel Hammond Duncan, Sanjeev Jain, Mark Douglas Hummel, Vyas Venkataraman, Olivier Giroux, Larry Robert Dennison, Alexander Toichi Ishii, Hemayet Hossain, Nir Haim Arad

Patent number: 11100558Abstract: A recommendation service that utilizes a machine learning algorithm trained with association vectors is provided. To allow for filtering of unrelated items, a recommendation service generates vectors that represent a quantization of items within a browse node that are considered complementary or a substitute of a selected item. Using an association vector, a machine learning algorithm can be trained to determine whether a particular item recommendation is considered noise, complementary or a substitute. Thereafter, the recommendation service can utilize the trained machine learning algorithm to filter a set of recommendations to remove items considered to be noise or to prioritize items identified as complementary or a substitute.Type: GrantFiled: May 19, 2017Date of Patent: August 24, 2021Assignee: Amazon Technologies, Inc.Inventors: Gaurav Chanda, Sanjeev Jain
