Definition of columns

name
# of Cores	Number of used CPU cores
# of parallel FEM	Number of subdomain in meridional plane
# of parallel FFT	Number of parallelization for FFT
$N_{med}$	Number of nodes for fluid in a meridional plane
$N_{\phi}$	Number of nodes (modes) in longitudinal direction
Elapsed time	Elapsed (wall clock time) for one time step
Solver time	Elapsed (wall clock time) for linear solver (including communications)
Comm. time	Elapsed (wall clock time) for data communication
Efficiency	Parallel efficiency
SUs	Service unit for $10^{4}$ time steps (Core hours)

Elapsed time is evaluated by averaging over 100 steps and number of cores from “fort.702”
Solver time is evaluated by averaging over 100 steps and number of cores from “fort.705”
Comm. time is evaluated by averaging over 100 steps and number of cores from “fort.703”
