Output
The benchmark output includes the following information:
General information:
machine, system, release, and version are obtained by IMB_g_info.c.
The calling sequence (command-line flags) are repeated in the output chart
Results for the non-multiple mode
After a benchmark completes, three time values are available, extended over the group of active processes:
Tmax - the maximum time
Tmin - the minimum time
Tavg - the average time
The time unit is μ.
Single Transfer Benchmarks:
Display X = message size [bytes], T=Tmax[μsec], bandwidth = X / T
Parallel Transfer Benchmarks:
Display X = message; size, Tmax, Tmin and Tavg, bandwidth based on time = Tmax
Collective Benchmarks:
Display X = message size;(except for Barrier), Tmax, Tmin; and Tavg
Results for the multiple mode
-multi 0: the same as above, with min, avg over all groups.
-multi 1: the same for all groups, max, min, avg over single groups.
