Technologies for automatic processor core association management and communication using direct data placement in private caches

A method for data communication, the method comprising:

• receiving, by a host fabric interface of a computing device and via a communication interface connected to a network, a first message from another computing device connected to the network;
• determining, by the host fabric interface, whether an association table that associates network addresses and virtual memory addresses with each of a plurality of processor cores includes a first entry, wherein the first entry associates one or more parameters of the first message to a destination processor core of the plurality of processor cores of the computing device;
• causing, by the host fabric interface, a data transfer agent associated with the destination processor core to obtain message data of the first message in response to determining the association table includes the first entry;
• determining, by the data transfer agent, whether a private cache that is accessible by the destination processor core and inaccessible by the other processor cores of the plurality of processor cores includes modified data;
• and
• writing, in response to a determination that the private cache does not include modified data and by the data transfer agent, the message data from the other computing device to the private cache.

One or more non-transitory computer-readable storage media comprising a plurality of instructions that in response to being executed cause a computing device to:

• receive, by a host fabric interface of the computing device and via a communication interface connected to a network, a first message from another computing device connected to the network;
• determine, by the host fabric interface, whether an association table that associates network addresses and virtual memory addresses with each of a plurality of processor cores includes a first entry, wherein the first entry associates one or more parameters of the first message to a destination processor core of the plurality of processor cores of the computing device;
• cause, by the host fabric interface, a data transfer agent associated with the destination processor core to obtain message data of the first message in response to determining the association table includes the first entry;
• determine, by the data transfer agent, whether a private cache that is accessible by the destination processor core and inaccessible by the other processor cores of the plurality of processor cores includes modified data;
• and
• write, in response to a determination that the private cache does not include modified data and by the data transfer agent, the message data from the other computing device to the private cache.
