A time period is received from a user over which memory settings of a microservice are to be dynamically managed. Memory settings for the microservice are stored in a configuration file. During the time period, memory utilization of a set of memory regions provided by a process virtual machine for execution of the microservice is monitored. The memory utilization of each memory region is analyzed to identify memory regions that have been over-utilized and memory regions that have been under-utilized. For each memory region identified as being over-utilized or under-utilized, a memory setting in the configuration file and corresponding to an identified memory region is changed. After the change and once the microservice has entered an idle state, a command is generated to restart the microservice so that the changed memory settings can take effect.

In a further embodiment, a system on a chip integrated circuit (SoC) is provided that includes an active base die including a first cache memory, a first die mounted on and coupled with the active base die, and a second die mounted on the active base die and coupled with the active base die and the first die. The first die includes an interconnect fabric, an input/output interface, and an atomic operation handler. The second die includes an array of graphics processing elements and an interface to the first cache memory of the active base die. At least one of the graphics processing elements are configured to perform, via the atomic operation handler, an atomic operation to a memory device.

A technique for maintaining synchronization between two arrays includes assigning one array to be a preferred array and the other array to be a non-preferred array. When write requests are received at the preferred array, the writes are applied locally first and then applied remotely. However, when write requests are received at the non-preferred array, such writes are applied remotely first and then applied locally. Thus, writes are applied first on the preferred array and then on the non-preferred array, regardless of whether the writes are initially received at the preferred array or the non-preferred array.

A memory module may include a first memory device configured to be controlled by a host memory controller, to transmit/receive data to/from the host memory controller in a first mode, and to transmit/receive data to/from a module memory controller in a second mode, a second memory device configured to be controlled by the module memory controller and to transmit/receive data to/from the module memory controller in the second mode, and the module memory controller configured to monitor control of the first memory device by the host memory controller, to exchange data such that the data is transmitted/received between the first memory device and the second memory device in the second mode, and to control the second memory device.

A method for using an access triggered architecture for a computer implemented application is provided. The method receives a set of data at a designated functional block associated with a system memory location; performs an operation at the designated functional block, using the set of data, to generate a result, wherein the operation is performed each time information is received at the designated functional block; and returns the generated result to the system memory location.

The described embodiments include a computer system having a multi-level memory hierarchy with two or more levels of memory, each level being one of two or more types of memory. The computer system handles storing objects in the multi-level memory hierarchy. During operation, a system runtime in the computer system identifies an object to be stored in the multi-level memory hierarchy. The system runtime then determines, based on one or more attributes of the object, that the object is to be pinned in a level of the multi-level memory hierarchy. The system runtime then pins the object in the level of the multi-level memory hierarchy. In the described embodiments, the pinning includes hard pinning and soft pinning, which are each associated with corresponding retention policies for pinned objects.

Systems and methods are provided herein for efficient local caching of data tiered to cloud storage to help reduce the bandwidth cost of repeated reads and writes to the same region of a stubbed file, increase the performance of write operations, and increase performance of read operations to portions of a stubbed file accessed repeatedly. When operations are directed toward data tiered to the cloud, the data can be read from cloud storage and stored within a local cache. A cache tracking tree can be generated and used to track file regions of a stub file, cached states associated with regions of the stub file, a set of cache flags, and other file and mapping data. For example, the cache state of regions of a stub file can be tracked including a cached data state, a non-cached state, a modified state, or a truncated state. Operations directed toward stubbed files can then look to the cache tracking tree to determine the most efficient way to access, retrieve, or operate on the data that maximizes local file system performance while reducing network activity.

A system-on-chip includes a magnetic random access memory and a security interface. The magnetic random access memory includes a plurality of memory areas, each of the plurality of memory areas having a different security level. The security interface circuitry configured to: identify a memory area from among the plurality of memory areas based on a received memory address associated with a received memory command; determine a security level associated with the identified memory area; and perform a memory operation on received data based on the received memory command and the determined security level.

A technique for maintaining synchronization between two arrays includes assigning one array to be a preferred array and the other array to be a non-preferred array. When write requests are received at the preferred array, the writes are applied locally first and then applied remotely. However, when write requests are received at the non-preferred array, such writes are applied remotely first and then applied locally. Thus, writes are applied first on the preferred array and then on the non-preferred array, regardless of whether the writes are initially received at the preferred array or the non-preferred array.

A memory system includes a nonvolatile memory module and a first controller configured to control the nonvolatile memory module. The nonvolatile memory module includes a volatile memory device, a nonvolatile memory device, and a second controller configured to control the volatile memory device and the nonvolatile memory device. The first controller may be configured to transmit a read request to the second controller. When, during a read operation according to the read request, normal data is not received from the nonvolatile memory device, the first controller may perform one or more retransmits of the read request to the second controller without a limitation on a number of times that the first controller performs the one or more retransmits of the read request.
