The file sizes output from "du -s" are quite different from "ls -la", but they are the same as those from "ls -las".
The file sizes from "du -s" and "ls -las" are in units of disc blocks and reflect the actual space taken by the files. A disc block is usually 512 bytes ... but it depends on the system.
The output from "ls -l" is how much data there is in each file up to the EOF marker. The EOF marker may be part-way through a disc block.
On one of my systems a single byte text file takes 8,192 bytes of disc space.

tau2profile
TAU2PROFILE(1) Tools TAU2PROFILE(1)
NAME
tau2profile - convert TAU tracefiles to TAU profile files
SYNOPSIS
tau2vprofile [-d directory] [-s snapshot_interval] {tau_tracefile} {tau_eventfile}
DESCRIPTION
This program is generated when TAU is configured with the -TRACE option.
The tau2profile converter takes a single tau_tracefile (*.trc) and tau_eventfile (*.edf) and produces a corresponding series of profile
files. The input files must be specified in that order, with optinal parameters coming afterward. Multi-file TAU traces must be merged
before conversion.
OPTIONS
-d Output profile files to the specified 'directory' rather than the current directory.
-s Output a profile snapshot showing the state of the profile data accumulated from the trace every 'snapshot_interval' time units. The
snapshot profiles are placed sequentially in directories labled 'snapshot_n' where 'n' is an integer ranging from 0 to to the total number
of snapshots -1.
EXAMPLES
The program must be run with the tau trace and tau event files specified in the command line in that order. Any additional arguments
follow. The following will produce a profile file array, from the TAU trace and event files merged.trc and tau.edf trace file:
tau2profile merged.trc tau.edf
The following will convert merged.trc and tau.edf to a series of profiles one directory higher. It will also produce a profile snapshot
every 250,000 time units:
tau2profile merged.trc tau.edf -d ./.. -s 250000
