TECHNOLOGIES FOR PERFORMANCE INSPECTION AT AN ENDPOINT NODE

摘要

Technologies for monitoring communication performance of a high performance computing (HPC) network include a performance probing engine of a source endpoint node of the HPC network. The performance probing engine is configured to generate a probe request that includes a timestamp of the probe request and transmit the probe request to a destination endpoint node of the HPC network communicatively coupled to the source endpoint node via the HPC network. The performance probing engine is additionally configured to receive a probe response from the destination endpoint node via the HPC network and to generate another timestamp that corresponds to the probe request having been received. Further, the performance probing engine is configured to determine a round-trip latency as a function of the probe request and probe response timestamps. Other embodiments are described and claimed.

1. A source endpoint node of a network to monitor communication performance of the network, the source endpoint node comprising:
one or more processors; and one or more memory or data storage devices having stored therein a plurality of instructions that, when executed by the one or more processors, cause the source endpoint node to:
generate a probe request;generate, using a clock of the source endpoint node, a first timestamp;transmit the probe request to a destination endpoint node of the network communicatively coupled to the source endpoint node via the network;receive, in response to having transmitted the probe request, a probe response from the destination endpoint node via the network;generate, using the clock and in response to having received the probe request, a second timestamp; anddetermine a round-trip latency as a function of the first and second timestamps.
