摘要： The present invention provides a computer implemented method, apparatus, and computer usable program code for processing multiple interrupts for multiple packets concurrently. First, data packets are assigned one of a set of interrupt queues for a virtual adapter in response to detecting the data packets. Each of the interrupt queues is processed by one of a set of interrupt threads for executing an interrupt handler. Next, an interrupt is dispatched for each of the interrupt queues receiving the data packets. The data packets in the interrupt queues are concurrently processed by one of the set of interrupt threads.

摘要： A method, system, and computer program product for negotiating a smart maximum segment size of a network connection for a data transfer. A client request to initiate a network connection, which includes a first maximum segment size, is received at a server. The server calculates a second maximum segment size, wherein at least one of the first maximum segment size or the second maximum segment size is a cache line size aligned Ethernet frame size, or smart maximum segment size. The server determines the smaller of the first and second maximum segment sizes and sends the second maximum segment size to the client. The client then selects the smaller of the first and second maximum segment sizes, and sends an acknowledgement to the server to complete the connection. The smaller of the first and second maximum segment sizes is used for the network connection and subsequent data transfer.

摘要： An apparatus and method for an improved bulk read socket call are provided. With the apparatus and method, a new field, so_rcvlen, is added to the socket structure that identifies the bulk read size requested by the user. The kernel of the prior art recv( ) function is also modified so that it sets the so_rcvlen to the size requested by the user prior to the recv( ) function going to sleep and waiting for the full data size requested by the user. A new flag, SP_MSGWAITALL, is also provided in the socket structure. In the TCP input processing, when data is received for a particular socket, the current setting of the SP_MSGWAITALL is checked. If the SP_MSGWAITALL flag is set, it is determined whether the amount of data stored in the socket receive buffer is less than the value of so_rcvlen. If not, the TCP input processing does not wake up the recv( ) thread. However, for every alternate segment, the TCP input processing sends back an acknowledgment (ACK). In the TCP output processing, when the SP_MSGWAITALL flag is set and the amount of data in the socket receive buffer is less than so_rcvlen, the full window is advertised. Once the TCP input processing determines that there is at least an amount of data in the socket receive buffer equal to the value of so_rcvlen, the TCP input processing will wake up the recv( ) thread and the SP_MSGWAITALL flag is reset.

摘要： A computer implemented method, apparatus, and computer usable program code to determine whether an acknowledgment packet from an end point acknowledges receipt of unsent data in response to receiving the acknowledgement packet over a connection with the end point. A determination is made as to whether acknowledgement packets for unsent data have been received sequentially a selected number of times over the connection in response to the acknowledgement packet being for unsent data. The acknowledgment packet is dropped if acknowledgement packets have been received sequentially the selected number of times over the connection.

摘要： A method, system and computer-usable medium are presented for pausing a software thread in a process. An instruction from a first software thread in the process is sent to an Instruction Sequencing Unit (ISU) in a processing unit. The instruction from the first software thread is then sent to a first instruction holding latch from a plurality of instruction holding latches in the ISU. The first instruction holding latch, which contains the instruction from the first software thread, is then selectively frozen, such that the instruction from the first software thread is unable to pass to an execution unit in a processor core while the first instruction holding latch is frozen. This causes the entire first software thread to likewise be frozen, while allowing other software threads in the process to continue executing.

摘要： A method, apparatus, and computer instructions for transferring data from a memory to a network adapter in a data processing system. The frame size for a transfer of the data from the memory to the network adapter is identified. If the frame size is divisible by a cache line size without a remainder, a valid data length is set equal to the length field. However, if the frame size divided by the cache line size results in a remainder, the length field is set to align the data with the cache line size. The data transfer is then initiated using these fields.

摘要： The present invention relates to means, a method and a computer program product of administrating in a computer system a global data element shared by a multitude of exploiters within said computer system for reducing contention among said exploiters. It is suggested to execute a first step by a first exploiter of accumulating one or a multitude of modifications performed by said first exploiter with respect to the current contents of said global data element into a first local data element not shared by other exploiters. In a second step executed by the first exploiter a size of the accumulated modifications in the first local data element with respect to the current contents of the global data element is determined. Moreover it is determined, if said size exceeds a specified quantum. If said size exceeds the specified quantum, the global data element is updated with the accumulated modifications as new contents.
