Patent number: 9965392Abstract: Existing multiprocessor computing systems often have insufficient memory coherency and, consequently, are unable to efficiently utilize separate memory systems. Specifically, a CPU cannot effectively write to a block of memory and then have a GPU access that memory unless there is explicit synchronization. In addition, because the GPU is forced to statically split memory locations between itself and the CPU, existing multiprocessor computing systems are unable to efficiently utilize the separate memory systems. Embodiments described herein overcome these deficiencies by receiving a notification within the GPU that the CPU has finished processing data that is stored in coherent memory, and invalidating data in the CPU caches that the GPU has finished processing from the coherent memory. Embodiments described herein also include dynamically partitioning a GPU memory into coherent memory and local memory through use of a probe filter.Type: GrantFiled: August 24, 2016Date of Patent: May 8, 2018Assignees: Advanced Micro Devices, Inc., ATI Technologies ULCInventors: Anthony Asaro, Kevin Normoyle, Mark Hummel

Patent number: 9898416Abstract: In a multithreaded data processing system including a plurality of processor cores and a system fabric, translation entries can be invalidated without deadlock. A processing unit forwards translation invalidation request(s) received on the system fabric to a processor core via a non-blocking channel. Each of the translation invalidation requests specifies a respective target address and requests invalidation of any translation entry in the processor core that translates its respective target address. Responsive to a translation snoop machine of the processing unit snooping broadcast of a synchronization request on the system fabric of the data processing system, the translation synchronization request is presented to the processor core, and the translation snoop machine remains in an active state until a signal confirming completion of processing of the one or more translation invalidation requests and the synchronization request at the processor core is received and thereafter returns to an inactive state.Type: GrantFiled: December 22, 2015Date of Patent: February 20, 2018Assignee: International Business Machines CorporationInventors: Guy L.

Patent number: 9830094Abstract: A system, method, and computer program product is described for providing dynamic enabling and/or disabling of protection information (PI) in array systems during operation. A storage system receives a request to transition a volume from PI disabled to PI enabled during regular operation. The storage system synchronizes and purges the cache associated with the target volume. The storage system initiates an immediate availability format (IAF-PI) process to initialize PI for the associated data blocks of the volume's storage devices. The storage system continues receiving I/O requests as the IAF-PI process sweeps through the storage devices. The storage system inserts and checks PI for the write data as it is written to the storage devices. The storage system inserts PI for requested data above the IAF-PI boundary and checks PI for requested data below the IAF-PI boundary. The transition remains an online process that avoids downtime.Type: GrantFiled: June 23, 2015Date of Patent: November 28, 2017Assignee: NetApp, Inc.Inventors: Mahmoud K. Jibbe, Charles D. Binford, Wei Sun
