Hi, One of my colleagues has been trying to benchmark the maximum performance of Mellanox ConnectX-3 Infiniband cards using IP over IB. He was able to use smp_affinity to distribute Ethernet packet-receive interrupts across many cores, and specify on which cores the interrupts occurred. With IPoIB, smp_affinity successfully moved interrupts to a specific core, but he was unable to distribute the IPoIB interrupts onto multiple cores. Is there a design detail of how IPoIB works that prevents this? Does anyone know of a setting, configuration value, or feature that we're overlooking to allow this, or is it impossible? Thanks in advance for your feedback.
