An immersion cooling system including an electronic device including a plurality of boards, the electronic device being configured in the immersive cooling system to be immersed in refrigerant that a reservoir is configured to accommodate, a pump array including a plurality of pumps disposed inside the reservoir, each pump of the plurality of pumps configured to individually generate a flow of the refrigerant by performing a discharging of the refrigerant, and a controller, the controller being configured to individually control an operation of each pump of the plurality of pumps, determine a board of the plurality of boards that requires cooling, identify a pump corresponding to the determined board among the plurality of pumps, and increase a flow quantity of the refrigerant discharged from the identified pump.

System, apparatus, and method with immersion cooling

Disclosed is a processor for performing a speculative execution for an out-of-order execution. The processor may include: a core; and an L1 cache memory, and the core may include a speculative track buffer (STB) storing speculative track information in order to track the speculative instruction when a speculative instruction is recorded in a reorder buffer (ROB), and a load queue (LQ) transmitting a commit doorbell signal or a restore doorbell signal for a first speculative block to which a first speculative instruction belongs to an L1 cache memory based on first speculative track information of the first speculative instruction when a speculative success or a speculative failure of the first speculative instruction included in the speculative instruction is decided, and the L1 cache memory may include a write buffer.

Processor and operation thereof to revoke cache memory states utilizing write-back buffer

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

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.
