Existing current workaround is using wall time for the whole ADDA run and
compare it with total processor time (first two times in log). So the true
matvec time is approximately equal to ( [Number of solutions (usually 1 or
2)]*[matvec products (for one solution)] + [Total wall time] - [Total time]
)/[Total number of matvecs] .
Marcus tested that this approach leads to consistent results for
moderate-to-large runs. There are, however, two drawbacks:
- the accuracy of [Total wall time] is 1 s, insufficient for smaller runs.
- there are a number of other reasons that may be causing the difference
between these two timings, including other tasks executed by the operation
system.

In addition to previous comment - the accuracy of wall time results should be
much better with r1350.
