Measuring minimum switch port metric retrieval time and impact for multi-layer infiniband fabrics
In this work, we seek to gain an understanding of the InfiniBand network processing limitations that might exist in gathering performance metric information from InfiniBand switches using our new LDMS ibfabric sampler. The limitations studied consist of delays in gathering InfiniBand metric information from a specific switch device due to the switch's processor response delays or RDMA contention for network bandwidth.
