Patent number: 12130741Abstract: Systems, apparatuses, and methods for implementing a multi-tiered approach to cache compression are disclosed. A cache includes a cache controller, light compressor, and heavy compressor. The decision on which compressor to use for compressing cache lines is made based on certain resource availability such as cache capacity or memory bandwidth. This allows the cache to opportunistically use complex algorithms for compression while limiting the adverse effects of high decompression latency on system performance. To address the above issue, the proposed design takes advantage of the heavy compressors for effectively reducing memory bandwidth in high bandwidth memory (HBM) interfaces as long as they do not sacrifice system performance. Accordingly, the cache combines light and heavy compressors with a decision-making unit to achieve reduced off-chip memory traffic without sacrificing system performance.Type: GrantFiled: November 23, 2022Date of Patent: October 29, 2024Assignee: Advanced Micro Devices, Inc.Inventors: SeyedMohammad SeyedzadehDelcheh, Shomit N.

Patent number: 11436103Abstract: Replication of a filesystem or a mount point or share may replicate all data that it consists of irrespective of where the data is stored. Replication protects data irrespective of location. One method is to replicate the filesystem namespace as is while skipping the data outside of the appliance/machine so that replication cost and time are reasonable. The data outside of the machine, like cloud/tape data is protected differently. One example method includes a data protection operation configured to replication a namespace associated with multiple data tiers. During replication, data from one of the tiers is skipped while all of the namespace metadata is replicated. The recovery restores the namespace metadata and the data that was replicated from the other tier. This may be performed in connection with cyber security, for example when replicating multi-tier data to a vault.Type: GrantFiled: October 13, 2020Date of Patent: September 6, 2022Assignee: EMC IP HOLDING COMPANY LLCInventors: Nitin Madan, Kalyan C.

Patent number: 11429733Abstract: A method for sharing secret data between multiple containers. In response to the initial booting of an operating system instance in a container, a unique operating system identifier is generated for the operating system instance. A grant authority stores the unique operating system identifier in a reserved area of a secure storage device. In response to a request from the operating system instance to access secret data in the secure storage device, the grant authority determines whether the unique operating system identifier is stored in the secure storage device. The operating system instance may be granted access to secret data in the non-reserved area of the secure storage device.Type: GrantFiled: November 15, 2018Date of Patent: August 30, 2022Assignee: International Business Machines CorporationInventors: Klaus Werner, Jakob C. Lang, Joerg Schmidbauer, Angel Nunez Mencias

Patent number: 11392488Abstract: Methods, systems, and computer readable media for optimizing storage of application data in memory are disclosed. According to one method for optimizing storage of application data in memory, the method includes receiving application data associated with an application. The method also includes generating, using information about the application, information about a processor, and information about a memory, a memory map indicating one or more memory locations in the memory for storing the application data. The method further includes storing, using the memory map, the application data in the one or more memory locations. The method also includes executing, using the processor, the application that uses the application data.Type: GrantFiled: April 9, 2018Date of Patent: July 19, 2022Assignee: KEYSIGHT TECHNOLOGIES SINGAPORE (SALES) PTE. LTD.Inventor: Matthew R. Bergeron

Patent number: 11388271Abstract: A first event occurs at a first computer at a first time, as measured by a local clock. A second event is initiated at a second computer by sending a message that includes the first time. The second event occurs at a second time, as measured by a local clock. Because of clock error, the first time is later than the second time. Based on the first time being later than the second time, an alternate second time, that is based on the first time, is used as the time of the second event. When a third system determines the order of the two events, the first time is obtained from the first computer, and the alternate second time is obtained from the second computer, and the order of the events is determined based on a comparison of the two times.Type: GrantFiled: October 6, 2020Date of Patent: July 12, 2022Assignee: Cloudera, Inc.Inventors: David Alves, Todd Lipcon

Patent number: 11307904Abstract: A system-on-chip (SOC), includes a memory, a partition access module coupled to the memory, a partition requesting unit coupled to the partition access module, and a first input-output (IO) device coupled to the partition access module. The partition access module creates a first partition of the SOC. The first partition includes a first portion of a first processor, the first IO device, and a first portion of the memory. Based upon a partition request, the partition access module repartitions the SOC to create a dynamic partition. The dynamic partition includes the first portion of the first processor, the first input-output (IO) device, the first portion of the memory, and a second IO device not included in the first partition.Type: GrantFiled: December 18, 2018Date of Patent: April 19, 2022Assignee: ATI TECHNOLOGIES ULCInventors: Michael McLean, Philip Ng
