US Classification:

709213, 709215, 711147, 711152, 711153, 711129

Abstract:

A computing device having partitions, and a method of communicating between partitions, are disclosed wherein each partition comprises at least one address area readable but not writable from the other of the at least two partitions. In one embodiment one partition sends to the other partition a request for information, which information is in the other partition in an address area not accessible to the one partition, the other partition copies the information to an address area accessible to the one partition, and the one partition reads the information from the accessible address area. In another embodiment the at least one accessible address area of each partition includes a data area and a consumer pointer indicating the position to which that partition has read the data area in another partition.

US Classification:

370218, 709212, 709215, 710 22, 710 23, 370215

Abstract:

A local RDMA (Remote Direct Memory Access) network adapter that comprises a simplex switchless connection with a counterpart QP on a remote RDMA network adapter in an example is selected for a Queue Pair (QP). An apparatus in an example comprises a requester RDMA (Remote Direct Memory Access) session fail-over coordinator on a coherency domain that adds a session fail-over header to a front of a data payload sent by an RDMA computer program from the coherency domain. Upon termination, of an RDMA adapter not coherent with the coherency domain and in a communication path of the data payload, before delivery to the RDMA computer program of a receive completion notification for the data payload, the session fail-over header is employable by a responder RDMA session fail-over coordinator to reconstruct the receive completion notification.

US Classification:

709212, 709213, 709214, 709215

Abstract:

An apparatus in an example comprises an RDMA (Remote Direct Memory Access) network adapter located at an interface of a requester node coherency domain that sends an RDMA read request to a responder node coherency domain to flush into the responder node coherency domain data previously sent by the RDMA network adapter.

International Classification:

H04L 12/56

US Classification:

370389000, 370252000

Abstract:

A method for processing inbound and/or outbound data wherein a processing policy is determined for a quantum of data. A quantum of inbound data is received and a data notification for the received data is prepared. The notification for the quantum of received inbound data is delivered to a processor according to the processing policy. When selecting a quantum of outbound data, an outbound data work request for the outbound data is prepared and delivered to an output unit according to the processing policy.

International Classification:

G06F 17/30

US Classification:

707610, 707E17005

Abstract:

Systems and methods of fast synchronization failure detection in distributed databases are disclosed. An example of a method includes receiving a digest of a database stored at a sending node in a network, the digest broadcast by the sending node to N number of nodes in the network. The method also includes generating a digest of a database stored at a receiving node in the network. The method also includes comparing the generated digest to the received digest. The method also includes issuing a lost synchronization signal by the receiving node when the comparison indicates a change in the database stored at the sending node.

G02B 6/26

Abstract:

Thermal control is provided for external light sources for silicon photonics based pluggable modules. In one embodiment, an apparatus comprises a first circuit board; a light source disposed upon the first circuit board; a silicon photonics modulator; a connector comprising a first portion and a second portion, wherein: the first and second portions are physically matable and separable; mating the first and second portions of the connector optically couples the first and second portions, the first portion is disposed upon the first circuit board, and is optically coupled to an output of the light source, and the second portion is optically coupled to an input of the silicon photonics modulator; and a thermal controller to control a temperature of the light source. Some embodiments disable the light source when the connector is separated.

International Classification:

G06F 12/1027
G06F 12/1009

Abstract:

An example implementation in accordance with an aspect of the present disclosure includes an address translation table of a transparent router. In response to an add service request to add a service to at least a portion of a memory system, a first address to be affected by the service is identified. An affected entry of an address translation table of the transparent router is also identified. The affected entry corresponds to a data path including the first address. The affected entry is modified to cause its corresponding data path to point to a second address associated with the service.
