The example input files in this directory calculate binding energies for actin dimers. This is an example of a large biomolecule binding energy calculation that often requires parallel focusing.

1 The discrepancy in values between versions 0.4.0 and 0.3.2 is most likely due to three factors:
2 The discrepancy in values between versions 0.5.0 and 0.4.0 is most likely due to the following factor(s):
3 The discrepancy in values between versions 0.5.1 and 0.5.0 is most likely due to the following factor(s):
4 The discrepancy in values between versions 0.5.1 and 1.0.0 was due to the execution of the previous APBS tests on a PowerPC platform with the XLC/XLF compilers. Running with binaries compiled with gcc/gfortran or the Intel compilers gives identical results between versions 0.5.1 and 1.0.0.
