2018 Beta App Perf Snapshot memory stats

The new 2018 Beta Application Performance Snapshot is easy to use.  Question, for the "Memory Footprint" statistics for an MPI job how do I interpret this?  I ran a 16 rank job on 4 nodes, 4 ranks per node.  So is the Mean and Peak an average for 1 rank? Or an average footprint for 1 node? or what?

Hello Ron,

Currently APS shows Memory Footprint Average and Pick per rank. In html reports it you hover a mouse over "Peak" metric you can see a hint with the rank number with pick footprint.

I would highly recommend to use APS standalone package from IDZ that we have just posted. It is newer than what it inside Studio Beta and has particular fixes on memory footprint calculations. Standalone package installation should be simple - just unzip, source vars and it is ready.

Thanks & Regards, Dmitry
