Hello all,
I am trying to finish putting together my test case for pbsa membrane
routines.
I am having trouble getting one of the test cases to pass consistently on
both 32 and 64 bit machines.
Apparently, the norm of the residual vector and convergence reported
differ by enough to trigger a "possible FAILURE" to be reported.
Other than that the two output files are indistinguishable (except timing
of course since the 64 bit machine has a faster processor). E.g. all
energies, etc. match exactly
This error persists even if working off of a clean pull from the pbsa_dev
branch on both machines, so the code for the source files is identical on
both machines.
Has anyone else experienced this issue as well (or anything similar), and
if so, do you have any idea how to go about fixing it?
For reference, I've included the .dif file and the cpuinfo of the two
machines.

(output of the .dif file is below)
