The real definition of the $\text{pH}$ is not in terms of concentration but in terms of the activity of a proton,
\begin{equation}
\text{pH} = - \log a_{\ce{H+}} \ ,
\end{equation}
and the activity is a dimensionless quantity. You can think of the activity as a generalization of the mole frac...
I noticed that the exact same code took 50% more time to run on OpenMPI than Intel. I use the following syntax to compile and run:
Intel MPI Compiler: Redhat Fedora Core release 3 (Heidelberg), Kernel version: Linux 2.6.9-1.667smp x86_64
