bsf - benchmark stats on all floating point values in a (binary) structured
file
bsf [parameter=value]
bsf computes some numbers
for all the floating point values in a structured file, which can then
be used against previously obtained number in an effort to assert proper
regression.
The output will mean, rms, min, max and number of points.
This
program can be used by users who want to provide some regression in their
NEMO scripts. See EXAMPLES below.
The following parameters are
recognized in any order if the keyword is also given:
- in=
- input file name
[???]
- test=test-string
- If given, this is the resulting string that should
have been obtained. Default: none
- fmt=C-fmtP
- C-Format string for the 4 floating
point values output. [%g]
- eps=
- In some next version this accuracy parameter
can control if the regression numbers need to agree within some fraction.
Default: not used and not implemented.
- label=label-string
- By default the
input file name is reported, but with label= you can override this. Particularly
useful when unix pipes are used.
Here are some examples of the stats
of the masses and phase space coordinates of a plummer sphere with 10 particles
and seed=123. The last example is to show that the output of %g (the default)
and %f do differ.
mkplummer - 10 seed=123 | bsf -
0.0140845 0.896875 -4.6523 4.80925 71
mkplummer - 10 seed=123 | csf - - convert=d2f | bsf -
0.0140845 0.896875 -4.6523 4.80925 71
mkplummer - 10 seed=123 | csf - - convert=d2f | bsf - %f "0.0140845 0.896875
-4.6523 4.80925 71"
0.014085 0.896875 -4.652300 4.809249 71 FAIL
0.0140845 0.896875 -4.6523 4.80925 71 expected
When you run these with seed=0, you will see the first and last number
do not change, because mkplummer by default value centers the snapshot
(zerocm=t).!q
