摘要
Technologies for Ethernet gateway congestion management in HPC architectures include a high-performance computing (HPC) switch with an Ethernet gateway that is configured to receive an HPC packet from an HPC fabric via a virtual lane (VL) of the Ethernet gateway. The Ethernet gateway is further configured to determine whether the HPC packet corresponds to a backward error correction notification (BECN), identify one or more priority code points (PCPs) of the HPC packet corresponding to a BECN as a function of the VL on which the HPC packet was received, and generate an Ethernet priority-based flow control (PFC) frame that includes the one or more identified PCPs in a header of the Ethernet PFC frame. Additionally, the Ethernet gateway is configured to transmit the Ethernet PFC frame to an Ethernet fabric as a function of the one or more identified PCPs. Other embodiments are described herein.
