Message splitting and aggregation in a multi-stage electrical interconnection network are disclosed. A method of operating an electronic device comprised of computing devices, includes splitting, into segments, a message to be transmitted from a first of the computing devices, transmitting the segments to a second of the computing devices through a multi-channel that is based on an electrical connection between the first computing device and a plurality of switches, wherein the multi-channel includes channels respectively including electrical connections, the electrical connections connecting the first computing device with the second computing device, and reconstructing the message by aggregating the segments in the second computing device, wherein a bandwidth of the multi-channel transmitting the segments is greater than a maximum bandwidth of a single electrical connection of the electrical connections.

Message split-aggregation for multi-stage electrical interconnection network

A method of operating a hardware accelerator, includes loading a lookup table, mapping each of input data values of input data to an index of indexes in the lookup table based on an input data distribution of the input data, and obtaining output data values corresponding to the input data values using the lookup table. The output data values are proportional to corresponding softmax values of the input data values.

Method and apparatus for operating accelerator using softmax approximation

A method of operating an accelerator includes receiving, from a central processing unit (CPU), commands for the accelerator and a peripheral device of the accelerator, processing the received commands according to a subject of performance of each of the commands, and transmitting a completion message indicating that performance of the commands is completed to the CPU after the performance of the commands is completed.

Accelerator, method of operating the accelerator, and device including the accelerator

A method and apparatus with cosmic ray fault protection is included. A method includes obtaining cosmic ray information indicating at least one cosmic ray event, determining a soft error mitigation policy based on the cosmic ray information, accessing the soft error mitigation policy by a device, and based on the soft error mitigation policy, performing, by the device, a mitigation action that mitigates for soft errors related to the cosmic ray event.

Method and apparatus with cosmic ray fault protection

A processor-implemented data processing method includes: normalizing input data of an activation function comprising a division operation; determining dividend data corresponding to a dividend of the division operation by reading, from a memory, a value of a first lookup table addressed by the normalized input data; determining divisor data corresponding to a divisor of the division operation by accumulating the dividend data; and determining output data of the activation function corresponding to an output of the division operation obtained by reading, from the memory, a value of a second lookup table addressed by the dividend data and the divisor data.

Method and apparatus with data processing

An electronic device and method with on-demand accelerator checkpointing are provided. In one general aspect, an electronic device includes a host processor, and an accelerator configured to operate according to instructions transmitted by the host processor to the accelerator, wherein, a memory of the host processor and a memory of the accelerator are respectively checkpointed to a storage at respective different intervals, and in response to a determination that a failure has occurred in the host processor, the memory of the accelerator is checkpointed to the storage.

Electronic device and method with on-demand accelerator checkpointing

A garbage collection method of a data storage system having storage devices is provided. The method includes determining whether a garbage collection is needed in one of the storage devices, transferring a multicast garbage collection command from one of the storage devices to at least one other storage device in a write group through a multicast operation, and performing the garbage collection in one of the storage devices.

Storage device and garbage collection method of data storage system having the storage device

Provided are a multi-process device and an inter-process communication (IPC) method thereof. The multi-processor device includes a first processor, a second processor, a first memory connected to the first processor, and a second memory connected to the second processor. When an inter-process communication (IPC) operation is performed between the first processor and the second processor, data is exchanged between the first memory and the second memory.

Multi-processor device and inter-process communication method thereof

A data storage device includes a data storage device controller configured to control a storage medium, and a tag duplicate check unit to determine, when a frame is received from an initiator, the initiator, tag information, and a type of the sent frame and providing an interrupt to the data storage device controller if a same frame type and same tag information are received from a same initiator.
