An optimized communication technique is provided. A communication controller has a retransmission list and a destination control logic circuit. The retransmission list records an identification number of a communication transaction that failed to transmit from a source module to a destination module. The destination control logic circuit manages the retransmission list. When a tracker is released from a queue of the destination module, the destination control logic circuit requests the source module to retransmit the communication transaction to the destination module according to the identification number recorded in the retransmission list.

Implementations of the disclosure describe inferring social groups through patterns of communication. A method of the disclosure includes ascertaining, by a processing device, a proposed group of contacts from contacts of the user based on a correlation in geographic locations of communications between the user and the proposed group of contacts and a correlation in a type of medium of the communications, providing a recommendation that the user create a new list of contacts associated with the user from the proposed group of contacts, and responsive to the user indicating acceptance of the recommendation, creating the new list of contacts associated with the user from the proposed group.

A system and method for operating with profiles includes a head end associating a first account profile having first profile settings and a first identifier and a second account profile having second profile settings and a second identifier with a user account. A first user receiving device operates with the first profile settings. The head end communicates second profile settings to the first user receiving device and the first user receiving device operates with the second profile settings.

A receiver-directed congestion control system which provides receiver-directed apportioning by adding a bandwidth share indicator value to the acknowledgement messages sent by the receiver to the senders. In certain embodiments, bandwidth share indicator value comprises the number of senders seen by the receiver. In other embodiments, the bandwidth share indicator value may comprise a percentage bandwidth share allocated to the sender computer to allow for varying priorities between senders. In the acknowledgement message, each sender may also include the incast degree, which is programmed in the application, to the receiver. This strategy enables the receiver to send back the sender count to all the senders as soon the first sender's packets arrive, even before the rest of the senders' packets arrive. Thus, the sender count and the incast degree look-ahead enable the receiver-directed system to achieve accurate and faster convergence of sending rates, without any repeated adjustments.

Example embodiments provide a disaggregated memory appliance, comprising: a plurality of leaf memory switches that manage one or more memory channels of one or more of leaf memory modules; a low-latency memory switch that arbitrarily connects one or more external processors to the plurality of leaf memory modules over a host link; and a management processor that responds to requests from one or more external processors for management, maintenance, configuration and provisioning of the leaf memory modules within the memory appliance.

A communication configuration apparatus for constructing a communication topology structure based on a plurality of processing nodes may be included in a combined processing apparatus. The combined processing apparatus further includes an interconnection interface and other processing apparatus. The communication configuration apparatus interacts with other processing apparatus to jointly complete a computing operation specified by a user. The combined processing apparatus further includes a storage apparatus. The storage apparatus is connected to the communication configuration apparatus and other processing apparatuses, respectively. The storage apparatus is used for storing data of the communication configuration apparatus and other processing apparatus. A technical solution of the present disclosure may improve efficiency of inter-chip communication.

A device may include a processor system and an array of data processing engines (DPEs) communicatively coupled to the processor system. Each of the DPEs includes a core and a DPE interconnect. The processor system is configured to transmit configuration data to the array of DPEs, and each of the DPEs is independently configurable based on the configuration data received at the respective DPE via the DPE interconnect of the respective DPE. The array of DPEs enable, without modifying operation of a first kernel of a first subset of the DPEs of the array of DPEs, reconfiguration of a second subset of the DPEs of the array of DPEs.

Embodiments herein may present a multi-tile processor including a plurality of processor tiles, and a plurality of interconnects selectively coupling the plurality of processor tiles to each other. A first processor tile may include a memory to store a bulletin board to hold a message, an execution unit, and an encapsulated software module. The encapsulated software module may select a second processor tile coupled with the first processor tile by an interconnect to be a part of a signal pathway. The second processor tile may be selected based on a selection criterion of the signal pathway and the message held in the bulletin board. The encapsulated software module may post and read a message at the bulletin board stored in the memory, or read a message from a bulletin board stored in a memory of the second processor tile. Other embodiments may be described and/or claimed.

A global context object may be used to create context affinity between two or more commands executed at a remote computer. A local computer may access a connection pool to determine if a runspace exists for a particular context on the remote computer in which the command is to be executed. If the runspace does not exist in the connection pool, the local computer may create a runspace associated with a particular context and add the runspace to the connection pool. The local computer may receive result data of executed commands from a remote computer and store the result data for use by the global context object to create context affinity between two or more commands executed at the remote computer.

An information processing system includes: a processor in one information processing apparatus among information processing apparatuses coupled via a ring bus corresponding to a closed-loop bus; and a first memory, wherein the processor: generate a verification request for verification of completion of a write request after issuing the write request to a second memory in the information processing apparatuses; transmit the verification request to a subsequent information processing apparatus; transmit, when a request from a preceding information processing apparatus is not a verification request, the request to the subsequent information processing apparatus; transmit, when the request is a verification request to another information processing apparatus, the verification request and a request to the first memory to the subsequent information processing apparatus in order of receiving; and execute, when the request is a verification request to the one information processing apparatus, processing and generate a response of completion of the processing.
