Concurrent maintenance of an input/output (I/O) adapter backing a virtual network interface connection (VNIC) including receiving, by a hardware management console (HMC), a request to disconnect the I/O adapter from a computing system, wherein the computing system comprises a logical partition and virtual I/O server; instructing, by the HMC over a communications link, the virtual I/O server to deconfigure and remove the server VNIC driver; determining, by the HMC, that a replacement I/O adapter is installed on the computing system; and in response to determining that the replacement I/O adapter is installed on the computing system, instructing, by the HMC over the communications link, the virtual I/O server to add and configure a replacement server VNIC driver.

System and method for dynamically managing message flow. According to the example embodiments, an intermediary network device or a client device dynamically manages the flow of messages received from an electronic exchange by analyzing the client device's capabilities, such as CPU utilization. Based on a percentage of total CPU utilization, the level of throttling is dynamically adjusted, such that if the percentage of CPU utilization, or load, increases, then throttling is increased from a lower level to a higher level. Similarly, if the percentage of CPU utilization decreases significantly enough, then throttling is decreased to a lower level.

A system, apparatus and method for enabling a FIFO-like (first-in-first-out) communication between a plurality of executing processes that are distributed throughout a computing system. Embodiments exploit locality in the hierarchy of the cache memory and communication busses within the computing system to enable the passing of messages or streams of bytes with a low latency and high throughput. In addition, this allows for participating components to be very simple, or very sophisticated, but still benefit from the improved communications patterns.

A method includes using a network interface controller to monitor a transmit ring, wherein the transmit ring comprises a circular ring data structure that stores descriptors, wherein a descriptor describes data and comprises a guest bus address that provides a virtual memory location of the data. The method also includes using the network interface controller to determine that a descriptor has been written to the transmit ring. The method further includes using the network interface controller to attempt to retrieve a translation for the guest bus address. The method includes using the network interface controller to read the descriptor from the transmit ring.
