摘要： In data processing systems that use a snoopy based cache coherence protocol and which contain a read only cache memory with a bounded range of addresses, a cache line hit is detected by assuming that, if an address contained in a request falls within the bounded range, the cache line is present in the cache memory for snoop results. This is equivalent to assuming that the cache line is marked as shared when it might not be so marked.

摘要： A fault tolerant computer system includes a fault tolerant data processing module which has means for detecting and correcting errors in the operation of the data processing module to maintain a high degree of data integrity. Data transmission control devices control the transmission of all data to the fault tolerant data processing module and the receipt of all data into the fault tolerant data processing module. Input/output terminals are coupled to the data transmission control means for receiving and transmitting data. A non-fault tolerant input/output module is coupled to transmit the data to the input/output terminals of the fault tolerant data processing module. This module includes a read device for transferring data to the fault tolerant computing system in response to requests from the data transmission control devices, and a firewall for preventing the non-fault tolerant input/output module from initiating transfers of data to the fault tolerant data processing module.

摘要： A method for transmitting messages between two processes includes creating a communications channel between a first channel adapter coupled to a client process and a second channel adapter coupled to a remote process. The method further includes reading a request message at the first channel adapter, segmenting the request message into a series of packets, assigning a sequence number to each packet, and transmitting the packets in order to the second channel adapter through the communications channel. The method further includes receiving the packets at the second channel adapter and sending at least one acknowledgement message to the first channel adapter in response to the received packets. The acknowledgement message has a packet sequence number field containing a packet sequence number and a payload containing a message sequence number, wherein the message sequence number identifies a complete message last received at the second channel adapter and the packet sequence number identifies a packet last received at the second channel adapter.

摘要： A system for servicing communication queues may include memory configured to store a hierarchical channel map having a plurality of levels wherein each bit of the lowest level is mapped to a different one of a plurality of communication channels and wherein each bit of each higher level is mapped to a group of bits at the next lower level. The system may include a host adapter configured to maintain the hierarchical bitmap wherein each bit at the lowest level is set if the channel to which it is mapped has a pending communication request and is cleared if not. Each bit of each higher level is set if at least one bit is set in the lower level group to which is mapped and cleared if not. The host adapter may be configured to examine the hierarchical bitmap in order to determine a next one of the communication channels to service. At each level of the hierarchical channel map a service mask may be provided to track which bits have already been traversed at that level. Multiple such service masks may be provided at each level to support different service classes.

摘要： In a bundled link system which partitions a data packet into varying size cells, a data packet is partitioned into a stream of cells of which the last two cells are partial cells. When the data has been partitioned so that less than the data required to fill two maximum size cells remains, the remaining data is divided into two cells where the cell size is selected so that each cell is larger than a predetermined minimum size. In a preferred embodiment, the remaining data is equally divided into partial size cells. In particular, in accordance with one embodiment, when there is less than two times the maximum size cell of data remaining to be partitioned in a packet and the remaining data is more than the maximum cell size, then the cell size used for the last two cells is the size of the remaining data divided by two.

摘要： In a switched configuration in which data links can be bundled to increase data throughput, the links in a bundle are ordered. A data sender sequentially transmits cells in the data packet over links in the bundle. For example, a first cell is transmitted over a first ordered link in the bundle. The next cell is transmitted over the next link in the bundle order and operation continues in a “round robin” fashion. The data receiver is informed in advance of the order of links in the bundle and expects cells to be distributed over the links in that order. The data sender transmits a bundle sequence number with each data cell. As each new data cell is transmitted, the bundle sequence number is incremented. The receiver uses the bundle sequence number to validate cell order, to detect lost cells, and to resynchronize cell order with the sender in the case of cell errors. Bundle sequence numbers are used on a single bundle on a single link, or “hop”, between a data sender and a data receiver. When the cells are received by the data receiver of a hop, the received bundle sequence numbers are replaced by new bundle sequence numbers generated by the data sender for transmission over the next hop.
摘要翻译：在可以捆绑数据链路以增加数据吞吐量的交换配置中，捆绑中的链路被排序。数据发送器通过链路中的链路顺序传输数据包中的小区。例如，第一小区通过该束中的第一有序链路传输。下一个小区以捆绑顺序通过下一个链路传输，操作以“循环”方式继续。数据接收者被提前通知捆绑中的链接的顺序，并且期望单元按顺序分布在链接上。数据发送器与每个数据单元发送一个包序列号。随着每个新的数据信元被传输，束序列号被递增。在单元格错误的情况下，接收器使用包序列号验证信元顺序，检测丢失的信元，并重新同步发送方的信元顺序。捆绑序列号在单个链路上的单个捆绑包上使用，或者在数据发送者和数据接收者之间使用“跳”。当小区被跳数的数据接收者接收时，接收到的束序列号由数据发送器生成的新的包序列号代替，用于在下一跳传输。
