A system includes having buffers and a processing device that receives a read request with a logical block address (LBA) value for a memory device, creates a logical transfer unit (LTU) value, to include the LBA value, that is mapped to a first physical address of the memory device, and generates command tags that are to direct the processing device to retrieve data from the memory device and store the data in buffers. The command tags include a first command tag associated with the first physical address and a second command tag associated with a second physical address that sequentially follows the first physical address. The processor further creates an entry in the read cache table for the buffers. The entry can include a starting LBA value set to the first LBA value and the read offset value corresponding to the amount of data.

An apparatus for managing a resource includes a buffer memory; and a processor configured to store, when target data for each of processes is acquired, the acquired target data in the buffer memory, the processes occurring asynchronously and periodically and being assigned degrees of priority, and assign a shared resource to some of the processes for which the target data is stored in the buffer memory in descending order of the priority at every predetermined timing, the shared resource being usable for each of the processes.

A network device in a communication network includes a controller and processing circuitry. The controller is configured to manage execution of an operation whose execution depends on inputs from a group of one or more work-request initiators. The processing circuitry is configured to read one or more values, which are set by the work-request initiators in one or more memory locations that are accessible to the work-request initiators and to the network device, and to trigger execution of the operation in response to verifying that the one or more values read from the one or more memory locations indicate that the work-request initiators in the group have provided the respective inputs.

An information processing apparatus capable of operating by switching between a first power mode and a second power mode with less power consumption than the first power mode is provided. The apparatus comprises a plurality of processors and a plurality of memories provided in correspondence with the plurality of processors, and controls power supplied to the plurality of processors and the corresponding plurality of memories. When operating in the second power mode, each of the plurality of memories stores a program to be loaded by a corresponding processor of the memory, and when one of the plurality of processors and the corresponding memory operate, power supply to processors and memories other than the one processor and the corresponding memory is limited.

Method and apparatuses for communicating instruction data items from a control apparatus to a device to be controlled are disclosed. The control apparatus receives a request for at least one instruction data item from a device and responds the request by sending a response message. The responding comprises selectively including at least one instruction data item in the response message based at least partly on determination whether the requested at least one data item has been sent before.

A client device sends a connection request to a virtual system in a Kubernetes cluster. The connection request identifies the client device and the application to which the request pertains. Based on a tenant associated with the client device, the virtual system connects the client device to an instance of the application. The instance of the application has access to data for the tenant but not for other tenants. Another client device of the tenant sends another connection request to the virtual system for a connection to another application. Because the tenant is the same, the instance of the other application may access the same data as the instance of the first application. In this way, applications for a single tenant may share data while maintaining the security of the data from other tenants.

Examples include techniques for managing high priority (HP) and low priority (LP) write transaction requests by a storage device. An embodiment includes receiving, at a storage controller for a storage device, a write transaction request from a requestor to write data to one or more memory devices in the storage device. When the write transaction request is for a high priority (HP) write, coalescing the write data into a transaction buffer in a memory of the storage device, sending an acknowledgment for the write transaction request to the requestor, and writing the write data into the one or more memory devices. When the write transaction request is for a low priority (LP) write, writing the write data into the one or more memory devices, and then sending an acknowledgment for the write transaction request to the requestor.

Methods and systems for conducting vector send operations are provided. The processor of a sender node receives a request to perform a collective send operation (e.g., MPI_Broadcast) from a user application, requesting a copy of data in one or more send buffers by sent to each of a plurality of destinations in a destination vector. The processor invokes a vector send operation from a software communications library, placing a remote enqueue atomic send command for each destination node of the destination vector in an entry of a transmit data mover (XDM) command queue in a single call. The processor executes all of the commands in the XDM command queue and writes the data in the one or more send buffers into each receive queue of each destination identified in the destination vector.

Systems and methods involve receiving requests to execute different processing tasks in a data processing system including first and second manycore processor units each having a processing unit and a programmable logic component, causing the tasks to be performed in different instances on the first processing unit and the first programmable logic component of the first manycore processor unit and on the second processing unit and the second programmable logic component of the second manycore processor unit including, in a particular instance, causing a particular task to be performed locally on the first programmable logic component based at least on a mapping consideration, and in another instance, partially reconfiguring the second programmable logic component to perform another task responsive to determining that the second programmable logic component is not already configured to perform the task.

A method and system for encrypting and reconstructing data files, including related metadata, is disclosed. The method involves separately encrypting data and metadata as chaining processes and integrating a plurality of encryption/encoding techniques together with strategic storage distribution techniques and parsing techniques which results in the integrated benefits of the collection of techniques. As disclosed, the content data is separated from its metadata, encryption keys may be embedded in the metadata, and in a content data encryption chaining process, the method chunks, encrypts, shards, and stores content data and separately shards and stores metadata, and stored in a flexible, distributed, and efficient manner, at least in part to assure improved resiliency In addition, the processes are preferably implemented locally, including at the site of the content data or a proxy server.
