To evaluate the trace size reduction of our MPI-aware prototype
we again applied the trace replay but this time with
enabled duration filtering and event reduction. We choose
a minimum duration of 1 µs for the duration filter, i.e., all
function calls shorter than 1 µs are filtered. This way, all
short-running functions are eliminated while important routines
remain in the trace. Furthermore, we choose a memory
buffer size of 50 MiB to trigger the MPI-aware event reduction.
To produce the results without event reduction we use
memory buffers up to 2 GiB for OTF2 and 1 GiB for OTFX.
