Technologies for accelerator interface

A method comprising:

• receiving, by a network interface controller, a data packet;
• encapsulating, by the network interface controller, the data packet in an encapsulating network packet, wherein a payload of the encapsulating network packet includes the data packet;
• sending, by the network interface controller, the encapsulating network packet to an accelerator device for processing;
• receiving, by the network interface controller and from the accelerator device, an encapsulating response network packet which includes a version of the data packet after processing;
• providing, by the network interface controller, the processed data packet to a processor;
• receiving, by the network interface controller, a second encapsulating network packet, wherein the second encapsulating network packet is to encapsulate transaction data;
• and
• providing, by the network interface controller, the transaction data to the accelerator device to perform a transaction based on the transaction data.

A compute device comprising:

• circuitry for receiving a data packet at a network interface controller;
• means for encapsulating the data packet in an encapsulating network packet, wherein a payload of the encapsulating network packet includes the received data packet;
• circuitry for sending the encapsulating network packet to an accelerator device for processing;
• circuitry for receiving, from the accelerator device, an encapsulating response network packet which includes the data packet after processing;
• means for providing the processed data packet to a processor of the compute device;
• means for receiving a second encapsulating network packet, wherein the second encapsulating network packet is to encapsulate transaction data;
• and
• means for providing the transaction data to the accelerator device to perform a transaction based on the transaction data.

An apparatus comprising:

• a network interface controller and
• circuitry to provide transaction data to the network interface controller, wherein the transaction data is to indicate a transaction to be performed on an accelerator device and wherein the network interface controller is to:
• encapsulate the transaction data in an encapsulating network packet;
• send the encapsulating network packet to the accelerator device;
• receive a second encapsulating network packet, wherein the second encapsulating network packet is to encapsulate second transaction data;
• and
• provide the second transaction data to the accelerator device, wherein the accelerator device is further to perform a transaction based on the second transaction data.

An apparatus comprising:

• a network interface controller comprising an interface and circuitry, the circuitry to:
• provide a processed data packet to a processor, wherein the network interface controller is to receive the processed data packet in at least one packet and the processed data packet was processed by an accelerator device based on a request from the network interface controller sent in a first encapsulating network packet;
• receive a second encapsulating network packet, wherein the second encapsulating network packet is to encapsulate transaction data;
• and
• provide the transaction data to the accelerator device to perform a transaction based on the transaction data.
