[codes-ross-users] Replaying OTF2 traces

[Ghosh, Sayan]

Hi – I am trying to use CODES/ROSS to replay OTF2 traces  (generated using ScoreP) on network models, after consulting the latest CODES/ROSS tutorial: https://www.mcs.anl.gov/projects/codes/files/2017/08/codes-hoti-tutorial-v4.pdf

I had used 1024 processes to generate OTF2 traces of my application (assuming it will run in serial mode without mpiexec). Ideally I would like to run the replay on my local machine using 1024 logical processes, without using mpiexec. Perhaps my understanding is not right here, please help.
