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. OSU INAM v0.9.7 (03/07/2022) * Major Features & Enhancements (since 0.9.6): - Significantly improved page load performance for - Live switch page - Live jobs page - Live node page - Live link information page - Historic node pages - Historic jobs pages - Add support for refreshing charts when zooming in and out in historic switches page - Add support to show the number of data points found for an InfiniBand switch counters and time taken to fetch them for each port in the historic switch page - Enhanced debugging, error reporting, and logging capabilities on OSU INAM web-based user interface - Display "no data" for fields that have no data to display - Enhanced stability and performance in emulator mode - Add support to display historic job information while in emulator mode * Bug fixes - Fix issues when different time zones are used in the web UI and server - Fix issues with dates when collecting InfiniBand port counters - Fix issues on the web UI when date field is NULL or missing in database - Fix index out of bound exception when selecting a link between a cluster and switch - Fix index out of bound exception when phantomJS configuration is Invalid For downloading OSU INAM v0.9.7 and associated user guide, please visit the following URL: http://mvapich.cse.ohio-state.edu All questions, feedback, bug reports, hints for performance tuning, and enhancements are welcome.
