bpcmp 1.1.0

Comparison tool for ADIOS2 bp output

bpcmp

Utility which allows for the comparison of two ADIOS2 bp output. The user must specify the location of the output and can use verbose output, set the absolute and relative tolerances for float type variables, and specify attributes and variables to ignore.

Inspired by this gist.

Floating point comparison done using numpy allclose.

Install from PyPi:

pip install bpcmp

Install from source:

git clone [e-mail]:PrincetonUniversity/bpcmp.git
cd bpcmp
pip install .   # include the -e option to make the installation editable

All of the arguments are optional.

Argument	Description
-v LEVEL	Use for verbose output level (0,1,2) = (nothing, errors only, everything)
-r RTOL	Set the relative tolerance when comparing float variables (default is zero)
-a ATOL	Set the absolute tolerance when comparing float variables (default is zero)
--ignore-atts IGNORE_ATTS	Provide list of attributes to ignore
--ignore-vars IGNORE_VARS	Provide list of variables to ignore

bpcmp out1.bp out.bp -v 1 -r 0.000001 -a 0.0001 --ignore-atts att1 att2 --ignore-vars var1 var2

Also included is a bpdump utility for dumping the contents of ADIOS2 bp output to the screen:
