摘要： An instruction is provided to establish various operational parameters for an adapter. These parameters include adapter interruption parameters, input/output address translation parameters, resetting error indications, setting measurement parameters, and setting an interception control, as examples. The instruction specifies a function information block, which is a program representation of a device table entry used by the adapter, to be used in certain situations in establishing the parameters. A store instruction is also provided that stores the current contents of the function information block.

摘要： One or more message signaled interruption requests from one or more input/output (I/O) adapters are converted to I/O adapter event notifications. Each I/O adapter event notification includes the setting of one or more specific indicators in system memory and an interruption request, the first of which results in a pending I/O adapter interruption request. While a request for an I/O adapter interruption is pending, subsequent message signaled interruption requests are converted to I/O adapter event notifications, but do not result in additional requests for I/O adapter interruptions.

摘要： Systems, methods and computer program products for automatically triggering operations on a queue pair (QP). Methods include receiving a command at a remote direct memory access (RDMA) capable adapter. A trigger event element associated with the command is determined. The trigger event element is posted on a triggered QP. A triggeror element on a triggeror QP is posted, where the triggeror QP includes a reference to the triggered QP. A notification that the triggeror element has completed is received. The trigger event element is automatically initiated in response to receiving the notification.

摘要： An Infiniband flow control scheme disables credit based flow control so that transmission distances can be extended. An Infiniband credit based flow control suffers from round trip time lag that slows transmission rates. Disabling Infiniband credit based flow control enables back to back packet transmission because credit counts are ignored. Nonetheless, packets can be lost due to overruns in a receive buffer, therefore, packet drop detection mechanisms are employed so that the Infiniband receiver can send requests to the Infiniband transmitter to temporarily slow its Infiniband transmission rate.
摘要翻译： Infiniband流量控制方案禁用基于信用的流量控制，从而可以扩展传输距离。基于Infiniband信用的流量控制受到往返延迟的影响，从而降低了传输速率。禁用基于Infiniband信用的流量控制可以实现背包传输，因为信用计数被忽略。尽管如此，由于接收缓冲区中的超载，分组可能丢失，因此采用分组丢弃检测机制，使得Infiniband接收机可以向Infiniband发射机发送请求，以暂时减慢其Infiniband传输速率。

摘要： A low latency multicasting receive and send apparatus and method comprising low latency receive and send queues. In an InfiniBand® network each destination group of nodes (recipients) is identified by a unique Global ID (GID)+Local ID (LID). Each node whose ports are part of a multicast group identify themselves via a LID which identifies participating ports. When a switch receives such a multicast packet with a multicast LID in the packet's DLID field it replicates the packet to each of the designated ports. Each destination adapter at a receiving node receives the multicast packet and distributes copies of the packet to QPs in the host system that are registered for the multicast address.
