One example method includes transmitting, by an application running in a host CPU, a notification to an application in a coprocessor/accelerator indicating that inbound data generated by the application is ready, receiving, by the application in the coprocessor/accelerator, the notification and delegating, by the application in the coprocessor/accelerator, an IO command to the application running in the host CPU, forwarding, by the application running in the host CPU, the IO command to an OS of the host CPU, transmitting, by the OS of the host CPU, an IO request to an IO device, initiating, by the IO device, a P2PDMA to transmit data associated with the IO request to a memory of the coprocessor/accelerator, and processing, by the application in the coprocessor/accelerator, the data.

Userspace split data-centric heterogeneous computing architecture

A method comprises: determining whether an event triggering processing of data at a storage device occurs, the data being predetermined to be processed at a computing device associated with the storage device; in response to determining that the event occurs, determining available resources of the storage device; and in response to an amount of the available resources exceeding a first predetermined threshold, causing the storage device to process the data and provide the processed data to the computing device. As such, operations to be performed to data may be adaptively allocated, deployed and adjusted on the storage device and the computing device, so that computing capabilities of both the storage device and the computing device may be fully leveraged, and further the computing efficiency of the entire data processing system may be improved.

Methods, devices, and computer program products for processing data

Embodiments of the present disclosure relate to a method and apparatus for determining a location of device. The method comprises obtaining locations of at least three reference points associated with the device and determining the location of the device based on the locations of the at least three reference points. The embodiments of the present disclosure have advantages such as cheapness, easy implementation and easy installation, may provide an administrator with various management interfaces and monitoring interfaces, and expand the scope of applicability.

Locating method and a locating device

Embodiments of the present disclosure provide an apparatus for testing a storage network comprising a processor configured to generate a configuration signal in response to a test request; and a tester coupled to the processor and configured to, by the configuration signal, operate under different operation modes so as to test different to-be-tested objects in the storage network. The test request indicates an operation mode of the tester, wherein various types of to-be-tested objects in a storage network can be tested by one test device, at a low test cost and with more convenient operations.
