摘要： One exemplary method of assigning addresses in two or more address spaces with address fields of different lengths comprises defining address types, assigning a value to first bits at the high ends of the address fields to identify a first said address type, assigning second bits at the low ends of the address fields to identify addresses of the first said address type, and inserting different numbers of additional bits between the first bits and the second bits in the two or more address spaces.

摘要： A method and system for operating a computer system are disclosed. In at least some embodiments, the present invention relates to a method of operating a computer system that includes operating a first cell of the system in accordance with a first memory access configuration, and migrating a first attribute of a first core of the first cell to a second cell of the system. The method additionally includes configuring a portion of the first cell so that the first cell is capable of operating in accordance with a second memory access configuration, and migrating at least one of the first attribute and a second attribute from the second cell back to the first core of the first cell, whereby subsequently the first cell operates in the second mode of operation. In at least some embodiments, the first and second configurations are direct and agent access memory configurations, or vice-versa.

摘要： A system for moving checksums within memory utilizes a plurality of memory systems and a system manager. A first memory system has a first memory location that is correlated with a checksum indicator. The checksum indicator identifies the memory system that is storing the checksum of the value presently stored at the first location. The system manager dynamically moves the checksum to a destination memory location and updates the checksum indicator such that the checksum indicator identifies the memory system of the destination memory location. While the checksum is being moved, checksum updates may occur to the memory location from which the checksum was moved. Thus, after moving the checksum, the system manager updates the checksum with the value stored at the location from which the checksum was moved. As a result, the checksum stored in the checksum destination location should be sufficiently updated to enable data recovery.

摘要： A system comprises a plurality of computing nodes and a plurality of separate memory devices. A separate memory device is associated with each computing node. The separate memory devices are configured as partition memory in which memory accesses are interleaved across multiple of such memory devices. A protected portion of the partition memory is reserved for use by complex management (CM) code that coordinates partitions implemented on the system. The protected portion of partition memory is restricted from access by operating systems running in the partitions.

摘要： Disclosed in some examples, are methods, systems, devices, and machine-readable mediums which solve the above problems using a global shared region of memory that combines memory segments from multiple CXL devices. Each memory segment is a same size and naturally aligned in its own physical address space. The global shared region is contiguous and naturally aligned in the virtual address space. By organizing this global shared region in this manner, a series of three tables may be used to quickly translate a virtual address in the global shared region to a physical address. This prevents TLB thrashing and improves performance of the computing system.

摘要： A system for performing data error recovery includes a memory unit and a memory controller. The memory unit includes a plurality of memory locations, and the memory controller maintains a checksum in one of the memory locations. At various times, the memory controller receives requests to update the checksum with data values identified by the requests. In response, the memory controller combines the checksum with these data values and stores the foregoing data values into memory. In one embodiment, the memory controller stores the foregoing data values into a plurality of stacks based on which protection domains are associated with the data values. In response to a detection of a data error, the memory controller retrieves a plurality of the stored data values and recovers a previous state of a particular memory location by combining each of the retrieved data values to the checksum.

摘要： A data storage system utilizes a plurality of memory systems, at least one processor, and a mapping system. Each of the memory systems has memory and a memory controller for storing and retrieving data. The processor transmits requests for writing data values. These requests include bus addresses. The mapping system maps the bus addresses into memory addresses. The mapping system maps consecutive bus addresses such that the memory addresses mapped from the consecutive bus addresses are interleaved across a plurality of the memory systems. In response to the foregoing requests from the processor, the mapping system identifies checksum system identifiers that identify locations where checksum values to be updated based on the aforementioned data values are stored. The checksum system identifiers preferably identify each of the plurality of mapping systems so that the checksum identifiers and, therefore, the checksum updates that occur based on these checksum system identifiers are interleaved across these memory systems.
