Abstract: A system and method for supporting a scalable thread pool in a multi-threaded processing environments such as a distributed data grid. A work distribution system utilizes a collection of association piles to hold elements communicated between a service thread and multiple worker threads. Worker threads associated with the association piles poll elements in parallel. Polled elements are not released until returned from the worker thread. First in first out ordering of operations is maintained with respect to related elements by ensuring related elements are held in the same association pile and preventing polling of related elements until any previously polled and related elements have been released. By partitioning the elements across multiple association piles while ensuring proper ordering of operations with respect to related elements the scalable thread pool enables the use of large thread pools with reduced contention compared to a conventional single producer multiple consumer queue.

The work distribution parameters may define a number of CTAs that are launched to process the same work queue entries. Finally, the work distribution parameters may define a step size that is used to update pointers to the work queue entries.

Abstract: An application sends a first request to an operating system to provide a hardware device with direct memory access to contents of a virtual memory location in an application memory of the application, wherein the virtual memory location is mapped to a physical memory location. In response to determining that the virtual memory location is to be reclaimed, the application sends a second request to the operating system to unmap the physical memory location from the virtual memory location. The second request causes the virtual memory location to be mapped to a new physical memory location. Responsive to receiving an indication from the operating system that the request to unmap the physical memory location has completed, the application then accesses the new physical memory location mapped to the virtual memory location.

Abstract: Embodiments herein provide a testing apparatus (whether physical or simulated) for testing a non-core MMU in a processor chip. Unlike core MMUs, non-core MMUs may be located in a part of the processor chip outside of the processing cores in the chip.

Using the data provided in the translation requests, the non-core MMU performs virtual to physical address translations. The non-core MMU transmits the results of these translations to the MMU testor which compares these results to expected results to identify any design flaws in the non-core MMU.

Abstract: A PCI host bridge (PHB) includes a warm reset mode and a full reset mode. When a fatal error occurs, the type of fatal error is determined, a reset mode corresponding to that type of fatal error is determined, and a reset corresponding to the reset mode is performed. A full reset clears the error registers, status registers and configuration registers, which then requires the configuration registers to be reconfigured before the PHB can be reinitialized. A warm reset clears the error registers and status registers, but does not clear the configuration registers. A warm reset thus does not require the time to write to the configuration registers, and the PHB can be reinitialized using the existing configuration data in the configuration registers while link training is done in parallel. When initialization of the PHB after a warm reset is not successful, a full reset is performed.

Remaining available pending updates are ignored for the respective partially backed out operational system resource after the respective fully functional data indexing and access state is achieved to expedite system restart.

The array cells which are associated with the determined one or more bit positions are disabled.

Abstract: A method begins by a dispersed storage (DS) processing module transmitting a set of write commands for storing a set of encoded data slices in storage units of a dispersed storage network (DSN) and determining whether at least a first threshold number of write responses have been received within a response time period.

When the total number of responses have not been received within the other response time period, the method continues with the DS processing module issuing a sub-set of write commit commands corresponding to a response number of encoded data slices for which a response was received.
