Abstract: A method for data transfer includes receiving in a data transfer operation data to be written by a peripheral device to a specified virtual address in a random access memory (RAM) of a host computer. Upon receiving the data, it is detected that a page that contains the specified virtual address is marked as not present in a page table of the host computer. The peripheral device receives a notification that the page is not present and an estimate of a length of time that will be required to make the page available and selects a mode for handling of the data transfer operation depending upon the estimate.

Abstract: A method for processing data includes receiving in a peripheral device, which is connected by a bus to a host processor having host resources, a notification of a sleep state of at least one of the host resources. While the at least one of the host resources is in the sleep state, when the peripheral device receives data from a data source for delivery to the host processor, the peripheral device sends a message to the data source, which causes the data source to defer conveying further data to the peripheral device until the at least one of the host resources has awakened from the sleep state.

Abstract: A communication network includes multiple nodes, which are arranged in groups such that the nodes in each group are interconnected in a bipartite topology and the groups are interconnected in a mesh topology. The nodes are configured to convey traffic between source hosts and respective destination hosts by routing packets among the nodes on paths that do not traverse any intermediate hosts other than the source and destination hosts.

Abstract: A method for communication includes storing packets received from a sending node over a communication link in a receive buffer of a receiving node. The receive buffer includes one or more blocks having a first block size. A first credit count, corresponding to a number of available blocks in the receive buffer, is derived. The first credit count is converted to a second credit count so as to represent an available space in the receive buffer in accordance with a second block size, which is different from the first block size. A transmission rate of the sending node is controlled by publishing the second credit count to the sending node over the communication link.

Abstract: A method for memory access is applied in a cluster of computers linked by a network. For a given computer, a respective physical memory range is defined including a local memory range within the local RAM of the given computer and a remote memory range allocated to the given compute within the local RAM of at least one other computer in the cluster, which is accessible via the network using the network interface controllers of the computers. When a memory operation is requested at a given address in the respective physical memory range, the operation is executed on the data in the local RAM of the given computer when the data at the given address are valid in the local memory range. Otherwise the data are fetched from the given address in the remote memory range to the local memory range before executing the operation on the data.

Abstract: A method in a network node that includes a host and an accelerator, includes holding a work queue that stores work elements, a notifications queue that stores notifications of the work elements, and control indices for adding and removing the work elements and the notifications to and from the work queue and the notifications queue, respectively. The notifications queue resides on the accelerator, and at least some of the control indices reside on the host. Messages are exchanged between a network and the network node using the work queue, the notifications queue and the control indices.

Abstract: A network interface device includes a host interface for connection to a host processor and a network interface, which is configured to transmit and receive data packets over a network, and which comprises multiple distinct physical ports configured for connection to the network. Processing circuitry is configured to receive, via one of the physical ports, a data packet from the network and to decide, responsively to a destination identifier in the packet, whether to deliver a payload of the data packet to the host processor via the host interface or to forward the data packet to the network via another one of the physical ports.

Abstract: Remote transactions using transactional memory are carried out over a data network between an initiator host and a remote target. The transaction comprises a plurality of input-output (IO) operations between an initiator network interface controller and a target network interface controller. The IO operations are controlled by the initiator network interface controller and the target network interface controller to cause the first process to perform accesses to the memory location atomically.
