An integrated circuit (IC) including a plurality of processor cores, a plurality of graphics processing units, a plurality of peripheral circuits, and a plurality of memory controllers is configured to support scaling of the system using a unified memory architecture. For example, the IC may include an interconnect fabric configured to provide communication between the one or more memory controller circuits and the processor cores, graphics processing units, and peripheral devices; and an off-chip interconnect coupled to the interconnect fabric and configured to couple the interconnect fabric to a corresponding interconnect fabric on another instance of the integrated circuit, wherein the interconnect fabric and the off-chip interconnect provide an interface that transparently connects the one or more memory controller circuits, the processor cores, graphics processing units, and peripheral devices in either a single instance of the integrated circuit or two or more instances of the integrated circuit.

A data access system including a processor and a storage system including a main memory and a cache module. The cache module includes a FLC controller and a cache. The cache is configured as a FLC to be accessed prior to accessing the main memory. The processor is coupled to levels of cache separate from the FLC. The processor generates, in response to data required by the processor not being in the levels of cache, a physical address corresponding to a physical location in the storage system. The FLC controller generates a virtual address based on the physical address. The virtual address corresponds to a physical location within the FLC or the main memory. The cache module causes, in response to the virtual address not corresponding to the physical location within the FLC, the data required by the processor to be retrieved from the main memory.

A page directory entry cache (PDEC) can be checked to potentially rule out one or more possible page sizes for a translation lookaside buffer (TLB) lookup. Information gained from the PDEC lookup can reduce the number of TLB checks required to conclusively determine if the TLB lookup is a hit or a miss.

To improve performance of a storage system. The storage system includes a plurality of storage nodes that communicate via a network. Each of the plurality of storage nodes includes one or more controllers. At least one controller in the controllers specifies at least two controllers that allocate a cache sub-area where write data is stored based on a controller that receives the write data from a host and a controller that processes the write date, and the cache sub-area is allocated in the specified controllers.

Embodiments are directed to providing a secure address translation service. An embodiment of a system includes DRAM for storage of data, an IOMMU coupled to the DRAM, and a host-to-device link to couple the IOMMU with one or more devices and to operate as a translation agent on behalf of one or more devices in connection with memory operations relating to the DRAM, including receiving a translated request from a discrete device via the host-to-device link specifying a memory operation and a physical address within the DRAM pertaining to the memory operation, determining page access permissions assigned to a context of the discrete device for a physical page of the DRAM within which the physical address resides, allowing the memory operation to proceed when the page access permissions permit the memory operation, and blocking the memory operation when the page access permissions do not permit the memory operation.

A computer-implemented method, according to one approach, includes: initiating an I/O request using a primary cache, where the I/O request includes supplemental information pertaining to an anticipated workload of the I/O request. Performance characteristics experienced by the primary cache while satisfying the I/O request are also evaluated. The supplemental information and the performance characteristics are further used to determine whether to satisfy a remainder of the I/O request using the secondary cache. In response to determining to satisfy a remainder of the I/O request using the secondary cache, the I/O request is demoted from the primary cache to the secondary cache, and a remainder of the I/O request is satisfied using the secondary cache. However, in response to determining to not satisfy a remainder of the I/O request using the secondary cache, a remainder of the I/O request is satisfied using the primary cache.

A system for distributed storage agents includes at least one memory and at least one compute node comprising at least one agent module. The at least one agent module is configured to cause at least a portion of data stored in the at least one memory to be pushed to a destination in accordance with an agent access plan.

An embodiment of a memory device includes technology for a memory cell array logically organized in two or more banks of at least two rows and two columns per bank, and two or more local caches respectively coupled to the two or more banks of the memory cell array, where each local cache has a size which is an integer multiple of a memory page size of the memory cell array. Other embodiments are disclosed and claimed.
