  We present an updated version of the AFMPB package for fast calculation of
molecular solvation-free energy. The main feature of the new version is the
successful adoption of the DASHMM library, which enables AFMPB to operate on
distributed memory computers. As a result, the new version can easily handle
larger molecules or situations with higher accuracy requirements. To
demonstrate the updated code, we applied the new version to a dengue virus
system with more than one million atoms and a mesh with approximately 20
million triangles, and were able to reduce the time-to-solution from 10 hours
reported in the previous release on a shared memory computer to less than 30
seconds on a Cray XC30 cluster using 12, 288 cores.
