[Mvapich] Announcing the Release of OSU InfiniBand Analysis and Monitoring (INAM) Tool v1.1

[Subramoni, Hari]

The MVAPICH team is pleased to announce the release of OSU InfiniBand Network Analysis and Monitoring (INAM) Tool v1.1.



OSU INAM monitors InfiniBand clusters in real time by querying various subnet management entities in the network. It is also capable of interacting with the MVAPICH2-X software stack to gain insights into the communication pattern of the application and classify the data transferred into Point-to-Point, Collective and Remote Memory Access (RMA). OSU INAM can also remotely monitor several parameters of MPI processes in conjunction with MVAPICH2-X.

    - Support for up to 64 parallel insertions for multiple sources of profiling data

    - Support for up to 64 concurrent users to access OSU INAM with sub-second latency by using ClickHouse
