摘要： An input/output (I/O) device includes a host interface for connection to a host device having a memory, and a network interface, which is configured to transmit and receive, over a network, data packets associated with I/O operations directed to specified virtual addresses in the memory. Processing circuitry is configured to translate the virtual addresses into physical addresses using memory keys provided in conjunction with the I/O operations and to perform the I/O operations by accessing the physical addresses in the memory. At least one of the memory keys is an indirect memory key, which points to multiple direct memory keys, corresponding to multiple respective ranges of the virtual addresses, such that an I/O operation referencing the indirect memory key can cause the processing circuitry to access the memory in at least two of the multiple respective ranges.

摘要： An input/output (I/O) device includes a host interface for connection to a host device having a memory and a network interface, which is configured to receive, over a network, data packets associated with I/O operations directed to specified virtual addresses in the memory. Packet processing hardware is configured to translate the virtual addresses into physical addresses and to perform the I/O operations using the physical addresses, and upon an occurrence of a page fault in translating one of the virtual addresses, to transmit a response packet over the network to a source of the data packets so as to cause the source to refrain from transmitting further data packets while the page fault is serviced.

摘要： A network interface adapter includes an outgoing packet generator, adapted to generate an outgoing request packet for delivery to a remote responder responsive to a request submitted by a host processor and a network output port, coupled to transmit the outgoing request packet over a network to the remote responder. A network input port receives an incoming response packet from the remote responder, in response to the outgoing request packet sent thereto, as well as an incoming request packet sent by a remote requester. An incoming packet processor receives and processes both the incoming response packet and the incoming request packet, and causes the outgoing packet generator, responsive to the incoming request packet, to generate, in addition to the outgoing request packet, an outgoing response packet for transmission to the remote requester.

摘要： A network communication device includes a host interface, which is coupled to communicate with a host processor, having a host memory, so as to receive a work request to execute a transaction in which a plurality of data blocks are to be transferred over a packet network. Processing circuitry is configured to process multiple data packets so as to execute the transaction, each data packet in the transaction containing a portion of the data blocks, and the multiple data packets including at least first and last packets, which respectively contain the first and last data blocks of the transaction. The processing circuitry is configured to compute a transaction signature over the data blocks while processing the data packets so that at least the first data block passes out of the network communication device through one of the interfaces before computation of the transaction signature is completed.

摘要： A method of controlling a peripheral device includes generating, in a host processor, a control message for transmission to the peripheral device, and calculating a signature for the control message. The control message and the signature are written to an address in a system memory of the host processor, and the peripheral device is notified of the address, so as to cause the device to read the control message and the signature from the system memory.

摘要： An improved cartridge for holding a fluid sample with a small volume is disclosed herein. The cartridge has a test chamber and a vestibule through which the test fluids are inserted into the test chamber. Improved grips are flared-out to aid manipulation. The handle portion is reinforced to prevent flexing, and a prefabricated trough along the edge of the land surface prevents introduction of the adhesive into the region for analysis. The cartridge has a stopper having a dual sealing mechanism, which seals the test chamber inlet between the vestibule and the test chamber, and the mouth of the vestibule so that when the stopper is in place, the test chamber is closed to the admission of air or other contaminants. The vestibule is similarly closed against escape of the overflow from the test chamber. The stopper is composed of a single elastomer. An improved locking mechanism has two flexible walls on either side of the handhold that locks into their respective keepers on the cartridge to provide a secure lock. Additionally, an improved method for loading the cartridge allows for an even distribution of magnetically responsive particles contained within a fluid sample to be viewed in an array through the optically clear land surface portion of the cartridge.
摘要翻译：本文公开了一种用于保持具有小体积的流体样品的改进的盒。盒具有测试室和前庭，测试流体通过该前庭插入测试室。改进的手柄被展开以帮助操纵。手柄部分被加强以防止弯曲，并且沿着陆面表面的边缘的预制槽防止粘合剂引入该区域用于分析。盒具有一个具有双重密封机构的塞子，该密封机构密封前庭和测试室之间的测试室入口以及前庭的口，使得当止动器就位时，测试室被关闭以允许空气或其他污染物。前庭也相似地封闭，防止溢出物从测试室逸出。止动器由单个弹性体组成。改进的锁定机构在手柄的任一侧具有两个柔性壁，其锁定在其相应的保持器上，以提供安全的锁定。此外，用于装载盒的改进方法允许包含在流体样品内的磁响应颗粒的均匀分布，以通过盒的光学透明的陆面表面部分在阵列中观察。

摘要： A method for controlling access by processes running on a host device to a communication network includes assigning to each of the processes a respective doorbell address on a network interface adapter that couples the host device to the network and allocating instances of a communication service on the network, to be provided via the adapter, to the processes. Upon receiving a request submitted by a given one of the processes to its respective doorbell address to access one of the allocated service instances, the adapter conveys the data over the network using the specified instance of the service, subject to verifying, based on the doorbell address to which the request was submitted, that the specified instance was allocated to the given process.
