Provided are a computer program product, system, and method for using at least one machine learning module to select a priority queue from which to process an Input/Output (I/O) request. Input I/O statistics are provided on processing of I/O requests at the queues to at least one machine learning module. Output is received from the at least one machine learning module for each of the queues. The output for each queue indicates a likelihood that selection of an I/O request from the queue will maintain desired response time ratios between the queues. The received output for each of the queues is used to select a queue of the queues. An I/O request from the selected queue is processed.

Embodiments herein relate to a universal component interconnect express (UCIe) link that includes a mainband and a sideband. One or more pieces of logic may identify a data that is to be transmitted on the sideband. The logic may then identify, based on factors such as a characteristic of the data or a characteristic of the link, whether to transmit the data on the mainband. Other embodiments may be described and/or claimed.

The present disclosure relates to a distributed console server system. The system may have a server and a software module loaded onto the server for communications with a plurality of remote devices within a data center. A remote serial port unit may be included which is in communication with the server and which is controlled in part by the server and the software module. The remote serial port unit may be in communication with the plurality of remote devices. The remote serial port unit may include at least one of a first module including a plurality of RJ45 ports, or a second module including a plurality of USB ports.

For polling communication devices in a communication system including a host device and communication devices. The host device is connected to the communication devices via a clock line for transmitting a clock signal to the communication devices and via an arbitration line implemented with OR logic for receiving arbitration signal transmitted by the communication devices. Each communication device is configured to pull up or down the arbitration line for sending an arbitration signal when the communication device is ready to send data to the host device. Each communication device is configured to pull down the arbitration line for sending an arbitration signal when the communication device has no data to send to the host device. The host device (HD) is able to: send a clock signal on the clock line during an arbitration cycle, causing the communication devices to send respective arbitration signals towards the arbitration line, during the arbitration cycle, receive a final signal corresponding to an addition of the arbitration signals, during the arbitration cycle, resulting from the OR logic applied to the arbitration signals, detect the communication devices ready to send data based on the 1 bit of the final signal, select, among the detected communication devices, the communication device associated with the highest priority in a priority table containing the priorities associated with the communication devices, and poll the selected communication device to receive data from the selected communication device during a communication cycle.

Disclosed herein is a technique for managing I/O requests transmitted between a computing device and a storage device. According to some embodiments, the technique can be implemented by the computing device, and include providing at least one I/O request to a submission queue configured to store a plurality of I/O requests. In conjunction with providing the at least one I/O request, the computing device can identify that at least one condition associated with the submission queueand/or a completion queueis satisfied, where efficiency gains can be achieved. In turn, the computing device can (1) update an operating mode of the storage device to cause the storage device to cease interrupt issuances to the computing device when I/O requests are completed by the storage device, and (2) update an operating mode of the computing device to cause the computing device to periodically check the completion queue for completed I/O requests.

An input/output response relation data storage 5 stores input/output response relations which are inputted by the user and in each of which an I/O station for input and an I/O station for output are defined. For input/output response relations in each of which the I/O station for input differs from the I/O station for output and each of which needs communications between the I/O stations, an interchange searcher 9 searches for an interchange candidate with which to make the I/O station for input and the I/O station for output be the same as a result of interchanging either of the I/O station for input and the I/O station for output with another I/O station, an interchanger 10 performs an interchange, and a display 3 displays a result of the interchange.

A bus traffic control apparatus includes a sizing block, a traffic request controller and a bus master engine. The sizing block is configured to determine a data transmitting size of a bus master based on bus traffic information. The traffic request controller is configured to control transmission of data from the bus master based on the data, a destination of the data, the data transmitting size. The bus master engine is configured to transmit the data to the destination in the data transmitting size based on the data, the destination of the data, the data transmitting size and a request received from the traffic request controller.

An information processing device includes a memory, and a plurality of processor cores capable of accessing the memory. The plurality of processor cores respectively executes processes to be executed by the plurality of processor cores in accordance with execution priority levels of the processes, when a polling process for repeatedly determining, by means of polling, whether or not reception data for input/output processing is received is underway in one of the plurality of processor cores, executes the input/output processing in response to a determination, made by the polling process, that the reception data have been received, and when the polling process is not underway in any of the plurality of processing cores, executes the input/output processing in response to a processor interrupt issued upon reception of the reception data.
